Hosack Blog Index: 10.2.2010 to 6.6.2025

I recently published a list of essays. The list, however, was buried in another essay. I also didn’t make it clear that the essays posted to LinkedIn began in June 2016, but the first essay was posted in October 2010 on my blog at this location. The entire list has had quite a few additions since my last update and is indexed by date below.

The Relationship of Shelter and Space to Survival

 I asked Google for the essential elements of survival and got the following response:

“The fundamental requirements for survival include air, water, food, shelter, sanitation, sleep, space, and touch.”

I assume that “space” was chosen because “land” can be excessively occupied to threaten survival, but “adequate space on land” was too cumbersome in context. In fact, the unmentioned assumption throughout the sentence is “adequate quantity and quality”. Space on land, however, is my point of reference in this essay.

I expected to see “shelter” but was surprised by the presence of “space” in the Google sentence. Shelter and space are the building blocks of architecture and urban design. They have been associated with fine art rather than survival because we have been distracted by their final appearance. The importance of shelter and space to survival seems self-evident, but the fundamental issue is their quantity and quality on a planet that must share its space with the shelter we need and the environment our source of life requires.

SHELTER CONTEXT

Shelter mass combines with pavement and unpaved open space in quantities that produce a spectrum of physical intensity options. They range from “sprawl” to “excessive intensity” in defined project land areas. The issue of survival enters the picture because excessive shelter sprawl threatens to consume our source of life and excessive shelter intensity is a threat to our health, safety, and quality of life. The devil is in the definition of “excessive” and “intensity” because the terms have simply been undifferentiated ranges on the missing yardstick of “intensity”. We have been distracted from these measurements by the appearance of a shelter result that has always begun with these intuitive, unwritten intensity decisions for the land available. Google has reminded us that survival is at stake. Literature warns us to avoid judging a book by its cover. Architecture, urban design, city design, and city planning should judge both – in my opinion.

The relationship between shelter and space in the Built and Natural Domains is the least understood among the survival topics mentioned by Google. It involves a rather simple commandment, however. We must provide adequate shelter capacity for growing population activity within space that must be limited to coexist with that required by a Natural Domain that is its source of life.

The issue we face is the “quantity and quality” of space that must be provided for both the Built and Natural Domains, and the shelter capacity of the space allocated for the Built Domain, since it must also accommodate the arteries of movement, open space, and life support that serve its urban and rural phyla. The Natural Domain requires space to serve the ecology that is our source of life. The relationship is inherently unstable when human motivation remains growth without limits on limited land area.

SHELTER INTENSITY and CONTEXT

Shelter capacity options produce a spectrum of physical intensity results with “sprawl” at one end and “excessive intensity” at the other, but the spectrum of shelter capacity, intensity, and context has never been mathematically defined. These conclusions have remained matters of perception, intuition, and unsubstantiated opinion. In fact, sprawl is simply a degree of intensity, and the spectrum can be mathematically measured and predicted.

SHELTER CAPACITY

The “equations of shelter capacity evaluation” have been derived to produce intensity, intrusion, and context measurements from design specification values entered in their forecast models. The equations and models are included in a book of the same name. They represent the leadership vocabulary needed to mathematically measure, evaluate, predict, and lead the shelter capacity of land and the economic organization of activity for growing populations within geographic limits scientifically defined to protect their quality and source of life.

Shelter demand for activity has often been answered with unlimited sprawl or excessive intensity. One threatens our source of life and the other threatens our quality of life. Improvement will require the correlation of shelter capacity, intensity, and activity options to consistently produce economic stability and a desirable quality of life within limited geographic areas.

Shelter capacity is the amount of gross building area in square feet present, planned, or possible per buildable acre of designated project land area. It can be occupied by any activity permitted in a zoning district. It can be measured, predicted, and evaluated based on a building category forecast model and values entered in the category’s design specification template. The values entered can be measurements or design options correlated by the forecast model algorithm to produce consistent shelter capacity, intensity, intrusion, and context measurements. 

LEADERSHIP DECISIONS

Leadership decisions based on mathematical evaluation are the only way to emerge from the morass of undisciplined, emotional opinion that continues to promiscuously consume the land while overlooking the fundamental correlation and mathematical allocation required to achieve a desirable, economically sustainable quality of life– in my opinion.

In this discussion, “space” has meant land used for the construction of shelter, movement, open space, and life support in the Built Domain. It has also meant land in the Natural Domain that is our source of life. Defining the relationship between these two spatial domains, and the adequate quantities needed to serve each, will demand far more accurate attention, evaluation, and leadership than presently committed. Fortunately, the foundation for leadership opinion can be mathematical evaluation.

A FORECAST MODEL

I’ve discussed the building design categories, forecast models, design specification topics/values, and master equations related to shelter capacity measurement, evaluation, prediction, allocation, and land consumption in many essays. The discussions have focused on mathematical values entered to define topic quantities in the design specification module of a building design category forecast model. These project value options are correlated by the model’s algorithm to calculate their combined planning and design implications. These shelter capacity, intensity, and context implications can then be evaluated for their potential to establish correlated physical, social, psychological, environmental, and economic stability within neighborhoods, districts, cities, and regions. The caveat for the process is that the shelter capacity of the Built Domain cannot be permitted to consume its source of life.

Forecast Model G1.L1 in Table 1 illustrates the primary mathematical terms and equations associated with shelter capacity evaluation for the G1 Building Design Category when gross land area is given. The forecast model, given information, forecast objective, and design premise are explained in the first four lines of the model.

Optional design specification values have been entered into the 26 gray cells of Table 1 to illustrate the operation of the model. The equations in cells H3-H33 convert these percentage values to their equivalent sq. ft. values in cells G3-G33. The objective is to find the CORE value in cell G33 for use in the master equation located in cell B39. The master equation combines this value with the parking quantity (s), parking area (a), and floor quantity (f) values entered in cells A35, A36, and A44-A53 to find the gross building area (GBA) options listed in cells B44-B53. These gross building area options are key to the forecast and are a function of the floor quantity options (f) entered in cells A44-A53. All remaining planning and design implications predicted in cells C44-J53 are a function of the gross building area options predicted in cells B44-B53.

The measurement predictions in the Implications Panel of Table 1 have physical, social, psychological, environmental, and economic implications that can be organized and evaluated in relation to these measurements to build knowledge and leadership direction. This can assist in forming the knowledge needed to consistently improve context results without dictating appearance.

CONCLUSION

I was gratified to see “shelter” and “space” mentioned as essential elements of survival, but these elements are topic titles. They do not indicate the essential quantities and intensity levels required for the survival of growing populations on a limited planet with a desirable, sustainable quality of life.

The building design category classification system, specification topics, and equations supporting Shelter Capacity Evaluation are also topic names that require quantity and quality evaluation. The results can be used to build leadership knowledge. Knowledge itself will remain a mystery until consistent measurement, evaluation, correlation, and prediction produce desirable shelter capacity and activity allocation within sustainable geographic limits. This is the foundation needed to support the fine art and quality of life that can emerge - in my opinion.

The Nine Phases of Architecture

 

Ruskin’s seven lamps of architecture, “Sacrifice, Truth, Power, Beauty, Life, Memory, and Obedience”, describe a romantic response to its purpose.

I have read many comments regarding architectural education and practice over the years. A few seem to be generated by a misunderstanding of the scope involved. Others seem to be unaware of the complete path because the image may be fine art, but it is only one of many objectives. In my opinion, a great deal of disappointment stems from a misunderstanding of the path and priorities involved.

PATH

The architectural path, as I remember it, involves education over a 4–6-year period; apprenticeship over a 2-3-year period; licensing in one or more years; employment; and partnership. In fact, employment does not require a degree or a license and does not necessarily lead to a partnership. A partnership, however, requires a license but can be elusive.

PROFICIENCY

All aspiring students of architecture should be aware that the path is intended to produce proficiency in at least nine phases of architectural practice, but a lack of proficiency in the first two can make it difficult to escape specialization in one or more of the last seven.

Unfortunately, formal education must rely on apprenticeship and employment to teach proficiency in Phases 1-3 and 5-9. The educational focus on Phase 4 trains students to think like strategists without the proficiency needed to lead the effort. Apprenticeship opportunities cannot always be found, however, and tend to focus on specialization in phase 5, in my opinion, because this is where manpower is needed. This emphasis may be a misunderstanding of the path that has led to some of the comments I’ve read.

The following is my impression of the phases involved, and a lack of proficiency in the first two can make independent practice illusory.

1- BUSINESS ORGANIZATION and administration of architectural practice

2-CLIENT DISCOVERY and retention

3- SCOPE ASSESSMENT- the definition and evaluation of a client’s aspirations, spatial requirements, and related engineering services

PROGRAMMING - the definition of a client’s aspirations and spatial requirements

EVALUATION – assembly and evaluation of all project-related information. The investigation of survey limitations, deed provisions, environmental restrictions, utility service availability, soil bearing parameters, zoning regulations, building code requirements, the shelter capacity of land available or required, and so on are a few of the topics that are often involved.

4-STRATEGIC PLANNING and DESIGN correlation of the physical planning and engineering objectives required to shelter client aspirations and activity. creation of a strategic plan using logic to correlate the plans, spaces, services, materials, appearance, and engineering systems required to serve the shelter requirements and aspirations of an owner defined in the programming and evaluation phases of a strategic planning effort.

PLANNING EXHIBITS: Site plans, Floor plans, Engineering Correlation, Elevations, Sections, Details, Renderings/ Models, Cost Estimate

 

5- CONTRACTUAL DEFINITION and CORRELATION of OBJECTIVES

DESIGN DEVELOPMENT CORRELATION- involves refinement of schematic design concepts with a definition of the primary architectural and engineering objectives required to support a strategic shelter design goal and includes a cost estimate update.

WORKING DRAWING and SPECIFICATIONS CORRELATION– This phase of architectural effort defines in detail the strategic direction, primary decisions, and construction objectives implied by the earlier schematic design and design development phases of architectural contract preparation.

Site Package Correlation – defines all survey, grading, landscape, and utility features surrounding and serving the building(s)

Surveys/utility locations

Geophysical analysis/soil borings

Environmental analysis

 

Architectural Package Correlation – defines the plans, volumes, envelope, materials, finishes, specialties, and details of assembly required to shelter the functions of one or more owner activities.

Site plans

Floor plans

Elevations

Sections

Details

Schedules

Specialty Topics

 

Engineering Package Correlation– defines the engineering systems supporting the shelter objective 

Civil Package

Structural Package

Mechanical Package

Electrical Package

Plumbing Package

Specialty Packages

 

Specification Correlation –written descriptions of the materials and methods that must be used to complete each package objective. When complete, the definition becomes part of a contract that is submitted for building permit approval and offered to contractors for examination and bid submittal.

Cost Estimate Correlation - An estimate of design development construction cost is provided at the end of a design development to evaluate the strategic cost of the proposal presented.

6-CONTRACT ASSEMBLY and BIDDING

Contract Assembly

Building Permit Submission

Bidding

Advertisement for Bids

Addenda Preparation

Bidding Management/ Administration/ Award

 

7-CONTRACT AWARD

8- VERIFICATION OF TACTICAL PROGRESS involving periodic observation

Shop drawing review

Change/field orders

Construction observation

Pay Application Review/Approval

Substantial Completion Certification

 

9-VERIFICATION OF COMPLETION and FINAL OCCUPANCY

Architectural Approval

Final Payment Authorization

Public Occupancy Permit

 

I have always believed in the leadership promise of architectural education, evaluation, and correlation; but the logic, knowledge, and creative response required to produce a shelter solution for the activities of a client does not include the time or proficiency required to contractually define the objectives that must be completed. This contractual definition is bid and guides the tactics required to achieve the shelter goal. The definition demands the greatest number of manhours but does not appear as a priority until apprenticeship.

The difference between strategic planning, evaluation, and contractual definition should be understood by every aspiring architect. The transition from dream to reality, the contractual definition required, and the time required to gain proficiency may be a surprise for many whose comments I have read. I won’t even mention an unstable economy and lack of apprenticeship opportunities that can become roadblocks.

Those who wish to remain strategists should consider urban design and city planning in my opinion. These are fields that can benefit from the research, measurement, correlation, and knowledge needed to credibly provide shelter for the activities of growing populations within geographic limits scientifically defined to protect their quality and source of life. An architectural education, the equations of shelter capacity evaluation, relational database software, and G.I.S. software are some of the data science tools available to support the creative, strategic journey.

The Public Leadership Potential of Architecture

 

An architect’s planning, design, and correlation education represents an unrecognized leadership and research asset of public value in my opinion. Unfortunately, this formal education is diverted along an apprenticeship, licensing, and employment path focused on the correlation and contract assembly required to define the shelter investment goals of private interest. This puts the public interest at risk because architecture, urban design, and city planning are currently lacking a mathematical vocabulary and language capable of leadership evaluation and consistent direction toward shelter for the activities of growing populations within geographic limits scientifically defined to protect their source of life and their physical, social, psychological, environmental, and economic quality of life. “The Equations of Urban Design” has been written and self-published on Amazon to provide the vocabulary. The values evaluated and adopted for use in these equations represent a potential language that can be used to lead the future.

Tailoring Shelter Capacity to Meet Physical, Social, and Economic Context Objectives

 Shelter construction on a single parcel accumulates in cellular fashion and combines with movement, open space, and life support systems to form a Built Domain anatomy that is not divinely created. It will continue until we have mathematical standards for shelter capacity evaluation that can mathematically measure, evaluate, predict, provide, limit, and lead the performance of all who plan, design, provide, invest, and consume land for shelter, profit, and revenue. Without a vocabulary and language capable of producing leadership knowledge and direction, shelter design, and real estate investment will continue following growth objectives with inadequate anticipation.

Architecture creates a shelter strategy called schematic design to protect and serve a client’s activity. It then works to complete a precise graphic and written contractual definition of the objectives that must be constructed with tactical effort to achieve the strategic goal. The result can be thought of as a cell within an urban anatomy, but there has been no mathematical ability to limit its growth, measure the intensity introduced, or the economic potential implied by occupant alternatives.

Cellular projects aggregate to form neighborhoods, districts, cities, and regions served by movement, life support and public open space arteries that add intensity, but its definition has remained a matter of opinion, political perception, and leadership confusion prompted by unreliable and inconsistent density and floor area measurements. (I won’t bother to defend this statement since I have written many previous essays on the topic.) This has made physical, social, and economic leadership by architecture, urban design, and city planning a hope without a language.

A mathematical language of intensity measurement and evaluation is needed to establish consistent leadership direction. The term can be defined in architectural terms as a spectrum of shelter capacity alternatives measured in gross building area potential per buildable acre. This capacity can be occupied by any eligible activity. It is formed by choices among building design categories, design specification values, floor quantity options, and a category master equation that produces gross building area predictions per buildable acre given the information measured and/or entered in a category forecast model.

I have written about this correlation and the context implications of shelter capacity, intensity, and intrusion measurements/predictions on many occasions, but have only provided the equations in a book entitled, “The Equations of Urban Design” available on Amazon. If you’re interested, you’ll have to build the forecast models from the information provided. I have never been convinced that there will be enough interest to warrant the expense of a web site devoted to the interactive use of these models, even though I have always believed there is a global need for more accurate shelter capacity leadership on a planet with limits that are no longer debatable.

I self-published the book mentioned and regret that I didn’t think of the title, “Shelter Capacity Evaluation”, at the time. The word “equations” in the title is misleading since each chapter is about a building design category and its mathematical capacity, intensity, and activity potential on a given land area. The correlation of shelter capacity, intensity, and activity to achieve economic stability and desirable context within limited geographic areas is the opportunity implied by the mathematical approach to design measurement, evaluation, and leadership presented. Derivation of chapter category master equations is presented at the end of each chapter for those who wish to verify the journey to each.

I would also like to amend the Table of Contents in my book, for those interested, with the version I’m attaching to this brief note. It does a better job of indicating the relationship between a building design category and its master equation.

The Third Dimension of City Planning, Zoning, and Urban Design

 

We can no longer depend on city planning master plans; zoning maps based on compatibility assumptions; and the belief that there is an unlimited Natural Domain available for annexation and consumption by the Built Domain. Weak assumptions and conflicting, uncorrelated regulations will remain a function of inertia until shelter sprawl, annexation, and excessive intensity are recognized as physical threats to our survival. It is not enough to recognize a threat, however. It must be met with an urban design strategy of equal magnitude involving the new tools and leadership correlation required to protect growing population activity with symbiotic shelter solutions in geographic areas scientifically limited to protect their quality and source of life, the Natural Domain.

Expanding the scope of attention to ensure that shelter remains an essential element and not a threat to survival will require a new strategy to achieve greater political credibility. This will depend on an expanded vision of the information-sharing, data science, relational databases, and geographic information analysis required for shelter capacity prediction, measurement, evaluation, and collaborative correlation in the search for knowledge that can help us learn to live within geographic limits.

(Shelter capacity is gross building area in sq. ft. (GBA) divided by the project buildable land area in acres. Gross building area potential on a given buildable land area, for the building design category (G1), is:

GBA = ((af) / (a+(fs))) * CORE

The G1 design category includes all buildings served by adjacent surface parking on the same lot, parcel, or land area. The square feet of gross building area planned or permitted per parking space is represented in the equation by (a). The square feet of parking area planned or permitted per parking space is represented by (s). Floor quantity (f) in the equation is the third dimension of city planning and zoning. I have discussed the derivation of CORE area from a standard set of design specification topics and value choices in numerous essays and will not repeat myself here. For the purposes of this discussion, CORE area is the project area remaining for primary building cover and parking cover after all other site improvement and open space areas are subtracted from the total project area.)

Urban design tools, and the information they provide, are needed to build convincing knowledge and arguments regarding land consumption, shelter capacity, spatial context; and the social, psychological, environmental, and economic implications of shelter aggregation choices. These choices involve building design categories, design specification values, floor quantity choices, and category master equations. They produce shelter options that are served by a city’s movement, open space, and life support systems. These are the four divisions that combine to form the currently parasitic urban and rural phyla of the Built Domain.

Architectural education teaches the formation of shelter space, form, function, and appearance needed to organize spaces that serve client activity and accommodate the essential engineering systems required on a given land area. This is the mental process of information-gathering, logical evaluation, and creative correlation that produces strategic options requiring leadership choices. It is the first milestone in architectural education, but the appropriate consumption of land is rarely considered. It is simply included as part of the problem to be solved, and the quantity is not tailored to either demand or capacity. Waste and/or excessive intensity is inevitable as the architectural strategy focuses on the internal success and external appearance of shelter while site planning deals with the land remaining.

We live with land surveys that do not accurately calculate the spectrum of shelter capacity alternatives available. They define an area, or quantity, that is considered a commodity for sale and use. The concept of shelter capacity evaluation considers a defined land area to be a unit in a city’s investment portfolio whose shelter capacity, intensity and activity options have revenue and investment potential that can be calculated. This unit potential combines to establish a city’s financial stability and affordable quality of life, but the ability to measure, forecast, evaluate, and adjust unit potential throughout a city’s land portfolio awaits the introduction of information-sharing systems and shelter capacity evaluation algorithms that are currently academic proposals.

The lack of mathematical urban/city design evaluation has led to city budgets based on history and future projections unable to accurately evaluate the total average annual revenue per acre that can be produced to balance the total average annual expense per acre needed to maintain and improve its desired quality of life.

Urban design expands the architectural universe of strategic evaluation. It is concerned with the formation, impact, impression and spatial context of places formed by the aggregation of shelter mass, shelter capacity, intensity, activity, movement, open space, and life support because these compositions affect a population’s physical, social, psychological, environmental, and economic quality of life. The goal is to limit the consumption of land for these places within a scientifically prescribed Built Domain defined to protect our quality and source of life. The political implications of the challenge are obvious, and the credibility required to lead will be no less than that needed to establish city planning, zoning, and building regulations in the 20^th century.

The relationship between land consumption and shelter capacity, intensity, and activity options has public revenue potential per acre that can be calculated. It may be the strongest argument for increasing research and knowledge regarding shelter capacity relationships that produce desirable places for people; since they can also produce revenue, financial stability, and an affordable quality of life within limited areas when consciously and mathematically organized.

Shelter capacity is a function of a given buildable land area, building design category decision, master equation, and choices regarding design specification values and floor quantity options. These decisions produce levels of measurable capacity, intensity and context that are occupied by activity. Shelter capacity, intensity, activity, and context decisions have mathematical relationships that can be used to balance the revenue potential of parcels across larger municipal land areas. These are the predictions that can establish the credibility of urban design recommendations. Their social, psychological, and environmental implications will require longer term research correlated with the conclusions from many related professions.

The Journey from Architecture to Urban Design

 

Architecture interprets client aspirations by outlining a shelter strategy to protect the client’s activity on a given land area. The outline leads to a precise graphic and written contractual definition of the tactical objectives that must be reached to achieve the strategic goal.

My guess is that the journey from shelter aspiration to strategic solution began long before recorded history. It began with a desire for refuge. The solution became a tree or cave. The need for improvement grew with recognition of the challenges represented by increasing demand. This eventually led to the evolution of engineering spin-offs as opinion began to recognize that observation, measurement, calculation, evaluation, and prediction were needed to build knowledge that could address architectural components with mathematical precision such as, but certainly not limited to, building structure, heating, ventilation, air conditioning, plumbing, lighting, electrical systems, sanitation services, and so on. The effort to improve opinion with knowledge to meet aspirations, however, was focused on individual projects until ignorance and abuse began to multiply and threaten the public health, safety, and welfare (quality of life). Ignorance claimed freedom to abuse, and the public eventually responded with minimum standards of conduct. The public emphasis on land use compatibility, however, did not prevent excessive intensity, annexation, pollution, and sprawl that may already be a threat to our source of life and occupants of the Natural Domain.

ARCHITECTURE

Architectural focus is dictated by client priorities that rarely have the public interest in mind. The strategic architectural planning emphasized by formal education, however, is one step away from the attention required to ensure that shelter remains an essential element of survival and not a threat. The step requires an expanded vision, however, that includes the information sharing, data science, relational databases, shelter capacity equations, economic evaluation, and geographic information systems needed to establish the credibility required to defend urban design recommendations in the public arena.

Architecture and urban design share the thought process required to form physical design strategy, but architecture continues from strategy assessment to focus on the contract definitions required to lead tactical decisions toward a client’s shelter objective. The limited cellular scope indicates to me that another architectural spin-off is required to address a shelter anatomy that is presently growing with limited restraint and direction.

URBAN DESIGN

We may now recognize that we need to shelter the activities of expanding populations within geographic limits scientifically defined to protect both their quality and source of life. In other words, we must share the land with the Natural Domain and build symbiotic shelter, movement, open space and life support systems in a scientifically limited Built Domain.

Architects have intuitively referred to this as urban design. It considers the shelter capacity, building mass, movement, open space, and life support implications of occupant activity within an urban composition containing the divisions of the Built Domain. It has had little attention because it has been unable to accurately correlate the shelter capacity, occupant activity, and revenue potential of land area with a city’s average expense per acre for its quality-of-life aspirations.

I should pause to explain that the term “shelter capacity” means the gross building area options in sq. ft. per buildable acre available. It is a mathematical function of the building design category chosen; the design specification values assigned; the floor quantity options considered; and the master equation involved.

The inability to accurately measure and predict shelter capacity options has made it impossible for a city to quickly and accurately correlate urban design alternatives with their economic potential and quality of life implications based on consistent measurement and evaluation of existing conditions. This has often left a city considering budget reductions and agricultural annexation for revenue that often proves inadequate over time; or stagnation and decline when land is unavailable and taxation, redevelopment, and eminent domain are unacceptable. This will continue until the shelter capacity, activity, intensity, context, and revenue potential of land can be mathematically measured, predicted, and correlated with the municipal budget required to maintain a desirable quality of life within geographic limits.

Urban design implies a public role leading to the formation of shelter capacity, occupant activity, building mass, pavement, open space, movement, and life support policies intended to produce an economically stable quality of life within geographically limited areas. Its recommendations will be contested by many until it can prove that they have social, psychological, environmental, and economic benefits. I’ve discussed this challenge and the mathematical approach to shelter capacity evaluation in many essays and will simply refer to the index of essays included in my essay, “Limited Land – Unlimited Growth”, published on my blog at www.wmhosack.blogspot.com and on LinkedIn.

CONCLUSION

The scope of client influence had to be limited by planning, zoning, and building regulations introduced in the 20^th century to protect the public health, safety, and welfare; but the scope of client influence is still too great, and the regulations too weak and mathematically uncorrelated, to meet the challenge. If you agree that shelter is required to survive on an unstable planet, and that it must be provided for the activities of growing populations in geographic areas scientifically limited to protect their source of life, then our quality of life will depend on our ability to mathematically define and correlate shelter capacity, intensity, activity, intrusion, and context options on a limited number of acres that are self-imposed in a new age of awareness.

Limited Land - Unlimited Growth + Latest Index of Essays

 

It seems obvious that land on a finite planet is limited and that our need for shelter must be balanced against our need to preserve land as a source of life for ourselves and all other species. All physical design disciplines related to shelter capacity evaluation will become more essential to survival as it becomes a more significant issue.

It is now possible to mathematically measure, evaluate, predict, adjust, and guide the shelter capacity, intensity, intrusion, and dominance implications associated with a chosen building design category and related template of design specification decisions. The result is a mathematical forecast of implication options based on the specifications and a range of floor quantity choices. It is also possible to measure the design specification decisions related to an existing building and enter them in a related building category template to measure the implications and evaluate the results to improve our knowledge regarding shelter design decisions.

The combination of shelter capacity, intensity, and activity on land determines its revenue and investment potential per buildable acre occupied. These considerations take their place next to our historic concerns for compatibility of adjacent activity to protect our health and safety because they determine the revenue and investment potential of a buildable acre. In municipal terms the allocation of shelter capacity, intensity, and activity per buildable acre within its total land area determines the annual yield it receives to support its operations, maintenance, improvements, and debt service.

Cities have not been prepared to monitor, evaluate, or plan the economic performance of land use, shelter capacity, and intensity allocation relationships at the parcel level of their incorporated area. They have had to rely on annual budget estimates based on experience. This is one reason why cities attempt to maintain unincorporated corridors of land for annexation that can provide new revenue to meet existing expenses that often prove inadequate over time as age, maintenance, and demand for service expense increases.

If this topic is of interest, I have written the following essays on my blog at www.wmhosack.blogspot.com to address various topics associated with the shelter capacity of land and the design decisions that face our growing demand for shelter and quality of life on a limited planet. Essays written after December 2020 are also included in LinkedIn. The first was written in September 2010.

FACING the REALITY of OUR DEPENDENCE on SHELTER and DESIGN

 

Quantities of building mass combine with quantities of parking, pavement, unpaved open space, and movement to produce measurable levels of physical intensity that affect our social, psychological, environmental, and economic health, safety, and welfare. Residential buildings produce density that is an inaccurate measure of the intensity levels produced by all building compositions. Floor area ratios are equally inaccurate. Without consistent measurement and evaluation of the shelter capacity, intensity, and intrusion quantities that combine to form the physical context levels we encounter, we will continue to debate philosophy and opinion without building the knowledge needed to form a consistent, credible, and convincing leadership language. We cannot overcome sprawl, excessive intensity, and unlimited consumption of the Natural Domain until we agree upon the goal and accept a mathematical language, consistent measurement discipline, and evaluation standards to define a leadership strategy that can lead the tactical efforts of many toward shelter for the activities of growing populations within geographic limits that protect their quality and source of life – the Natural Domain.

The Relationship of Shelter Capacity and Quality of Life to a Limited Built Domain

 

Until the political success of city planning and zoning in the 20^th century, we believed that the ownership of land came with sovereign authority over its use. This freedom came into question when public health, safety, and welfare were threatened by decisions that created incompatible adjacent activity, and shelter was constructed for human activity without adequate light, air, ventilation, and fire protection. The need to protect public health, safety, and welfare was accepted by the majority, but the concept of welfare protection has always been vague, open to interpretation, and limited by the concept of minimum standards.

The protection of social welfare has been associated with housing and human service programs serving qualified segments of the population. The protection of physical welfare has been associated with building regulation, land use planning, and the limitation of shelter density, intensity, activity, and appearance at specified locations. The protection of economic welfare has been associated with the scope of public revenue needed to support a city’s desired quality of life, or “welfare”.

Our success in leading cities toward physical, social, and economic stability has been symbolized by the shelter, movement, open space, and life support sprawl we have constructed; and the blight that has followed within land use patterns and textures (building height composition) that have not been balanced with the public revenue potential required to maintain their stability over extended periods of time.

There are several policy issues associated with an urban population’s “welfare” or ”quality of life” that may be too much for us to handle, but whose answers are inevitably reflected in the shelter, movement, open space, and life support we build.

The first issue is unlimited population growth and shelter demand on a limited planet. The second is geographic limits for a Built Domain that must be constrained to protect its source of life, the Natural Domain; the third is prevention of environmental and ecological degradation; and the fourth is economic instability produced by the mathematically uncorrelated relationship of shelter capacity, intensity, activity, and revenue potential on the land consumed.

Shelter capacity within a limited Built Domain that meets minimum acceptable standards will require a conscious correlation of population growth and activity with the shelter capacity, intensity, and revenue potential of every acre within the city. The nascent anticipation of the correlation required has been referred to as urban design within city districts and city design within larger urban areas. Unfortunately, we have not had the correlated information sharing, data science, geographic systems analysis, and mathematical shelter capacity evaluation needed to advance beyond observation and opinion.

Our response to population growth, land use misallocation, shelter capacity deficiency, inadequate public revenue, and blight has been an annexation of agriculture and the Natural Domain to expand the Built Domain with something new. Annexation permits a city to expand with political approval when land is available. When it has been available, cities have expanded for new revenue that can prove inadequate over time, and with little concern for the land consumed. The new revenue seeds the budget and solves any immediate deficit for currently elected officials. If increasing public maintenance cost per acre exceeds the public revenue produced per acre by the annexed area as it ages, the political/financial solution becomes a problem for others in the future.

When land is not available for annexation, an encircled city can be strangled by a land use pattern and permitted texture (building height composition) that no longer delivers the average revenue per acre required to meet a city’s total annual expense per acre for all desired services. Rezoning, redevelopment, and increased taxation are immediate reactions that occur on a difficult journey to adjust a city’s land use pattern, shelter capacity, and permitted activity toward an improved average revenue yield per acre that meets a city’s total annual and projected expense per acre. Eminent domain is rarely considered a viable political solution when city services can be reduced as an alternative. At this point, decline can become
a visitor without an invitation.

Annexation of land for new revenue has often been an inadequate solution producing sprawl and consumption of agriculture, not to mention the Natural Domain. This occurs because many, if not all, cities do not have the data science, information sharing, geographic information, and shelter capacity evaluation technology needed to evaluate the total average revenue produced per acre on every block and zone within its boundaries; or the mathematical ability to predict the revenue that could be produced by a revised collection of shelter capacity, intensity, and activity alternatives within these boundaries. They may not even know their total average expense per acre to operate, maintain, and improve their community. This means that annexation will consume land in a limited incorporated area but its ability to offset a city’s total annual expense per acre will be a guess masquerading as an estimate that directly affects a city’s economic stability.

This will continue to be a political challenge until anticipation, funding, technology, research, measurement, and evaluation produces the knowledge needed to consistently correlate population growth and activity with the shelter capacity, intensity, and economic potential needed to sustain quality of life in a limited Built Domain on a planet with unwritten laws of survival.

Think back and consider that science began as contentious opinion based on anticipation that required proof to establish credibility. Anticipation has never been our strong suit, but it is a prerequisite for creative design. Design decisions remain fine art opinion, however, until research, measurement, mathematics, and evaluation produce accepted conclusions that enable others to replicate performance and success over generations. This is the effort needed to step from individual anticipation and talent to the leadership language needed to guide our performance addressing sprawl, environmental degradation, economic instability, and quality of life. Our success will be symbolized by the scope and quality of shelter we provide within the limited areas of a Built Domain.
