Can a project team earn an Innovation credit for increasing the efficiency of necessary energy use during construction?
Project teams may pursue an ID credit for reductions in construction energy use related to lighting and temporary heat if the following conditions are met:For tables, see https://www.usgbc.org/resources/temporary-lighting-and-heat-leed-interpr.... Must show construction energy savings over duration of project exceeds 2% of predicted annual building energy use (EA1 design case energy model or CBECS if no energy model).2. No credit given for adjusting schedules or shutting down lighting and equipment during non-construction hours. It is assumed that standard practice is to turn lights and temporary heat off when not in use. 3. No credit given for permanent building systems used for lighting or temporary heat. 4. For temporary lighting: a. Calculate savings based on actual run times for all lamps compared to the same run times assuming lamps with an efficacy of 40 lumens per watt.i. Example: If a project uses 100 LED lamps of 12 watts, 800 lumens each, for 10 hours per day for 100 days, they would use 1,200 watts (1,200 kWh) to produce 80,000 lumens. A base case with 40 lumens per watt would use 2,000 watts (2,000 kWh).b. Security and life safety lighting must be on separate circuits from general lighting and only security and safety lighting can be on during unoccupied hours.5. For temporary heat:a. Demonstrate that temporary heating is required.b. Calculate savings based on actual run times for all heating compared to the same run times assuming a baseline system with a thermal efficiency of 78%.6. For all other conservation measures demonstrate that proposed measure is not standard practice by referencing the construction practices of three similar projects in the same location of the project building within the past 2 years.7. The submittal documentation shall include:a. A holistic, construction energy management plan including descriptions of all energy conservation measures.b. Quantitative performance analysis for each measure comparing the implemented energy conservation measure versus a standard baseline (typical construction practices) to demonstrate how the project team arrived at savings calculations.c. Product data for installed equipment.NOTES:The 2009 IECC requires that 50% of all permanent lamps be high efficacy lighting. The 2009 IECC, chapter 2 defines high efficacy lamps as compact fluorescent lamps, T-8 or smaller diameter linear fluorescent lamps, or lamps with a minimum efficacy of: 60 lumens per watt for lamps > 40 watts, 50 lumens per watt for lamps > 15 watts and ? 40 watts, and 40 lumens per watt for lamps < 15 wattsApplicable Internationally.
