Smith Group: Analysis of Alternative Integrated Building Systems
At the Energy 2001 Conference, Smith Group presented an energy cost study of alternative building systems.

Clayco Inc.: Raised Floor Workplace
Lawrence J. Chapman, Jr., principal of Clayco Inc., has compiled a cost comparison between a raised floor office building and a conventional office building. According to Clayco Inc., their experience with raised floor systems has been more economical in both initial construction and operating costs.
RTKL Associates: Analysis of Raised Access Floor vs. Conventional Distribution: Command & Control Center, Fort Stewart, Georgia
At the briefing at Ft. Stewart on 10/7/03 RTKL described the benefits of a raised access floor with underfloor air distribution, communications and power distribution as an integrated sustainable design solution. These benefits include flexibility in reconfiguration of workstation layouts, easy connectivity of power and data, increased ceiling heights and improved daylighting.
Davis Langdon: Costing Green: A Comprehensive Cost Database & Budgeting Methodology
This paper uses extensive data on building costs to compare the cost of green buildings with buildings housing comparable programs, which do not have sustainable goals. The foundations are also laid to analyze incremental costs over starting budgets, and to compare the costs for different specific measures and technologies.

Greg Kats : The Costs and Financial Benefits of Green Buildings
This report was developed for the Sustainable Buildings Task Force, a group of over 40 California state government agencies. It demonstrates conclusively that sustainable building is a cost-effective investment, and its finding should encourage communities across the country to "build green".

Ellerbe Becket: GSA Access Floor Study
The purpose of this report is to perform a Twenty-Five Year Present Value Analysis and study the use of access floor systems in GSA office facilities to determine the best value to the taxpayer and the government for open office plans. Three access floor systems were studied and compared to base building scenarios using a full blend ceullular floor in a steel framed building and a header duct system in a concrete framed building.
Sustainable Development Alternatives for Speculative Office Buildings:
A Case Study of the Soffer Tech Office Building

This report documents the analysis of sustainable design alternatives for the Tech Office Building - a two-story, 64,000 sq.ft. speculative office building developed by the Soffer Organization in Pittsburgh, PA (figure 1). The architects are Garder+Pope, and the mechanical/electrical consultant is RAY Engineering. The attached drawings show the plans, sections, elevations and system details of the building. The purpose of this study was to assess alternative enclosure, HVAC and lighting design options in terms of their environmental performance and cost-benefit justifications.
Massachusetts Institute of Technology: HVAC Systems Analysis
Over the past year, Vanderweil Engineers and the Stata Center Design Team have explored various options for the HVAC system in the Stata Center. Based on the results of this exploration, the Design Team proposed an HVAC system based on the displacement ventilation concept, which distributes conditioned air to occupied spaces through an accessible raised floor.
