" "LEED-CI v2.0 uses ASHRAE 90.1-2004 as the baseline, which provides this exemption in addendum M. It should be noted that to qualify for this exemption, the task lighting itself must be furniture mounted, be controlled by automatic shutoff, and comply with ASHRAE 90.1-2004 Section 9.4.1.4 (d).

"None" "None" "X" "LEED Interpretation" "5718" "2004-09-20" "Commercial Interiors" "Our project is a 15,000 sq.ft. naturally ventilated building (no HVAC system) for assisted senior living, located in an amenable microclimate in Hawaii. For an EAp2 credit inquiry dated 12/21/2002, you have prescribed that the project assumes (for the purpose of energy modeling only) that both the baseline and the proposed project have identical air conditioning systems. Our question is this: If both buildings have identical systems that are being added only for modeling purposes, could we assume the HVAC loads to be unregulated, and subtract them out (for both cases) of our calculations? Perhaps more to the point: although ASHRAE 90.1 says it is not applicable to buildings that are not conditioned, can we still model the remaining regulated energy loads and use the results to achieve EAc1 points? " "The modeling protocol presented here is not valid for EAc1 compliance. Please see IDc1 Credit Interpretation Ruling dated 8/1/2003 for additional information and reasoning. The EA TAG continues to research appropriate modeling methodologies for rewarding the design and construction of naturally ventilated buildings. The TAG is looking closely at ASHRAE 90.1-2001 Appendix G as a possible starting point for development of this modeling methodology. Unfortunately, no final determination has been made which enables recognition of this building\'s natural ventilation strategy at this time. " "None" "None" "LEED Interpretation" "5739" "2004-05-26" "Commercial Interiors" "Our project is a small building under 20,000 ft2 in area, with a simple rectangular geometry. Is it acceptable to use Energy 10 to calculate the energy cost budget? We plan to use the energy numbers for cost & usage from Energy 10, and document it in the LEED required format." "Energy-10 is acceptable software to use for energy modeling to earn LEED credit points for appropriate projects only. The software does have some significant modeling limitations such as the ability to model only two zones with simple residential and small commercial HVAC equipment. Its accuracy declines as it is used for larger buildings with more complex HVAC requirements such as separate perimeter zones. As long as the project can be modeled within the limitations of Energy-10, it could be considered for energy modeling under EAc1. Energy-10 will be acceptable for use within the following boundaries. Version 1.5 or higher must be used. The project must have two or less zones or building functions. The project should be external load dominant as opposed to internal load dominant. Projects with separate perimeter zones cannot use Energy-10. The HVAC systems in the project are limited to the systems available for modeling by Energy-10. Work-arounds for other systems will not be accepted without proper documentation and comprehensive explanation. The energy efficiency measures included in the proposed design must be able to be modeled directly by Energy-10. In general, the project should be a low-rise residential or light commercial structure of 10,000 square feet of conditioned floor space or less. The use of Energy 10 on larger facilities will be considered on a case-by-case basis.
