Does the roof meet the ASHRAE 90.1 standard, making it eligible for federal tax deductions?
The American Society of Heating, Refrigeration, and Air Conditioning Engineers established standard 90.1 to set minimum requirements for energy efficient building design. Adopted by the federal government in 1994, it sets the roof reflectance minimum for government facilities at 70% and the minimum emittance level at 75%. 3. Is a system LCA available? LCA, or life cycle assessment, is a science-based measurement of the environmental impact of a product through its entire life cycle, including material extraction costs, manufacturing waste, embedded energy, and potential for recycling and reuse. (See BD+C ‘s White Paper on LCA at: www.bdcnetwork.com/contents/pdfs/bd&clcawhitepaper.pdf .) 4. Is a roof tear-off required? In re-roof projects, an important environmental consideration is minimizing waste. Certain roofing systems can be installed over existing roofs, thereby speeding construction time, lowering costs, and reducing the number of runs to the local landfill. 5. Does the manufact
