CREWS 9: Prismetrix – Space, Value & Costs

OVERVIEW

PRISMETRIX: SPACE, VALUE & COSTS
Prismetrix is a comprehensive system of measurements and metrics based on recognized and accepted standards in Corporate Real Estate, Workplace and Services. Using these standards ensures that impartial, “apples-to-apples” comparisons are possible among a large group of diverse firms and facilities. They contain factors which can be normalized to adjust for differences outside the control of the participating organizations. Factors can include climate, local labor & material costs, locally available fuel types and costs, etc.

One of the most critical factors affecting Total Costs of Occupancy is space utilization. Once a building’s footprint is established, changes in the workplace are limited to a fraction of the total square footage. This is why early analysis is critical to achieving high-value design.

The Guerin Prism is the “capstone” of Prismetrix. It is a graphic algorithm that enables detailed analysis of the major elements of building design that drive space utilization. It is a powerful tool for Space Benchmarking and can be applied to a wide range of different building designs to compare their overall efficiency.

This chapter presents the following information:
• Brief overview of Guerin Prism methodology
• Prism Space, Value & Cost Applications
• Importance of the Perimeter Area Ratio
• “Apples-to-Apples” Space Benchmarking
• Potential Savings in CapEx and OpEx
• Case Studies from Guerin Associates

Prism

WHY A PRISM?
The Prism is a near-magical shape with unique features. Its transparent solid volume affects the speed of light passing through, refracting (separating and bending) the light according to its different wavelengths. Long, low-energy red wavelengths are least affected by the material, and pass through with the least angular change. High-energy violet and blue are most affected, and come through with the greatest deflection.

The passage of light is analogous to the hierarchy of space, value & costs in a building. White light represents Net Assignable space or “Building Muscle,” with the highest value and lowest cost. Red (Secondary Circulation) is next, followed by yellow (Support Space) and green (Common Area). Violet and blue light, with higher energy, represent costly Vertical Penetrations, such as exterior walls, columns, stairs, elevators, etc. Building “Skin & Bones” are most expensive to design and build, yet offer the lowest return in terms of business value.

The Prism offers a visual approach to analyzing, understanding, and illustrating how various designs affect the labor, materials, time and money that go into a building, and the actual value that results. High-value design provides the highest return of profitable, business-critical space with the lowest cost-intensive investment.

The Guerin Prism examines each level of architectural design, to identify gaps with optimal ratios at each level as early as possible. This avoids the need for costly redesign later in design stages, during construction or even after occupancy, when costs of change are prohibitive.

Comparison

1. 27,000 SF less new construction required to satisfy a specific building program and occupancy.
2. 27,000 SF more space within a new facility, available to accommodate additional occupants or uses.
3. Higher levels of occupiable area within an existing building planned for reconfiguration.

The floor plans below show revisions made to the physical model above with minimal impact on office layout. The plan on the left side contains redundant secondary circulation. Removing the excess circulation improves valuable Net Assignable SF by nearly ten percent.

Building Plan

Potential improvements in space utilization exist in many areas, and most can be identified early in the design process. Once a building’s footprint has been established, however, improvements are limited largely to Net Assignable Workspace and Secondary Circulation, which represent a fraction of the building’s total area.

This is why early analysis is critical to achieving high-value design. One example of an early diagnostic is the Perimeter Area Ratio (PAR), the relationship between a building’s perimeter and its internal floor area, which affects the Gross SF to Net Assignable Workspace Ratio. Here are examples of three different plans and PARs.

Perimeter = 400 LF
Area = 10,000 SF
PAR = 4.0

Basic Office Building Plan

Perimeter = 600 LF
Area = 20,000 SF
PAR = 4.2

Second Basic Office Building Plan

Perimeter = 1,200 LF
Area = 50,000 SF
PAR = 5.4

In addition to the greater inefficiencies of Gross to Net ratios, resulting in less Net Workspace, higher PAR ratios increase the complex, costly exterior walls, glass, stairs,  elevators and structural features.

Higher PARs call for higher justification.

CONCLUSION

WHY IT’S IMPORTANT
It’s essential to establish measurable goals and achievements. In order to accomplish this, CREWS managers need the most up-to-date tools, techniques and data to guide decisions. This is especially true in benchmarking costs against peer organizations. Prismetrix ensures that Total Costs of Occupancy are based on similar, applesto-apples criteria, equivalent scope and equal depth of analysis.

Objective, impartial data based on consistent definitions is even more important in Space Benchmarking. The Guerin Prism enables this, using definitions based on standards published by ANSI, ASTM, BOMA and IFMA. The case studies cited above illustrate the significant potential financial benefits of applying this methodology.
