Technology Management
(10 pts. total) A 6-story (10 feet per story) rectangular commercial building with a footprint of 6000 ft2 is being built by a developer on a previously developed 0.8 acre site on Long Island. The project is slated to cost $15 million. 1) Answer the following about the building with regard to LEED scoring in the Energy and Atmosphere category (base the energy usage on the included CBECS data below):
a. Estimate the following values: (2 pts.)
• Total baseline energy usage
• Reduction/generation in usage to earn 4 points:
o under EA Credit: Optimize Energy Performance, Option 1
o using on-site renewable energy generation
o using captured bio-methane from a nearby landfill
b. Based on at least three references (one for each bullet), discuss the feasibility of
meeting the reduction/generation in usage outlined in part.
(a). (2 pts.) c. Determine if a 40-ton HVAC system can earn points under Option 2 of EA Credit:
Enhanced Refrigerant Management if the system uses HFC-410a as a refrigerant.
(Assume 10 years of life, 150 total lb of refrigerant used, and default values for all others.) If not, propose two ways to allow the HVAC system meet the requirement
(may state this last part; no calculations are necessary).
2) Address the ability of the project to earn 3 points under Option 2 of MR Credit: Building Life
Cycle Impact Reduction. Use one reference to address how it can be done for each of the 3 impact areas you select, and what the benefits in terms of the 3 E’s are.
