~r The first aspect to be addressed, accurate cataloguing of baseline conditions, is presumed to be obtained using a computer-based simulation. Participation in the PGE Earth Smart Program would provide access to the DOE2 energy efficiency study, which would furnish the necessary information. If the decision is made not to participate in the PGE Earth Smart Program the results of a similar simulation must be obtained. The second aspect can be met by conducting formal building commissioning. At this point, it is unclear what level of effort is required to compty with the third aspect, which is to confirm the quantity of energy saved during a period of analysis. I am seeking clarification from the LEED Committee on this issue. Language from the Department of Energy's Infernational Performance Measurement and Verification Protocol pertaining to this credit is attached. ENHANCING INDOOR AIR QUALITY Credit 1: Basic Construction IAQ Management Plan After completion of construction and prior to occupancy, provision of cleaning requirements for ventilation system components and pathways exposed to contamination during construction. Section 15010-1.7 - Temporary Heating requires that if the permanent HVAC system is used for temporary heating of the facility during construction that the coils are pressure cleaned and the ductwork is vacuumed prior to occupancy. Section 15010- 3.9 - Cleaning requires that exposed portions of equipment be cleaned upon completion. To comply with the intent of this credit it is suggested that the contractor be required to do the following. Other strategies that are consistent with the intent of the credit can also be considered: 1. Develop an IAQ Management Plan for the construction process (add to section ~ 01520, Environmental Practices). The plan should include construction-related IAQ procedures in the pre-construction and construction progress meeting agendas. 2. Protect the ventilation system components during construction or clean them after completion of construction including the inside air contact surfaces. 3. Implement construction sequencing to reduce adsorption of VOCs by materials that act as "sinks." Sequence construction as follows: The application of wet and/or odor-emitting materials such as paints, sealants, coatings, etc. shall be made before dry/sink materials such as ceiling tiles, carpets, fabric-covered furnishings, etc. are installed. Credit 1: Advanced Construction IAQ Management Plan Reduce construction contaminants in the building prior to occupancy (e.g. du~t, particulates, water infiltration-related contamination, VOC's). Provide a minimum of 85% filtration, as determined by ASHRAE Standard 52.1 -1992, on return-side system components during construction and replace all filtration media prior to occupancy if the return air side of a system is used during construction. • The following is a suggested strategy to comply with the intent of this credit. Other strategies that comply with the intent of the credit can also be considered: 1. Comply with the intent of the Basic Construction IAQ Management Plan 2. Reduce construction contaminants in the building prior to occupancy. Make temporary ventilation a requirement in the General Conditions of the construction contract. Check for possible damage to the system from high humidity. Use 100% outside air ventilation (depending on climate) with air exhausted directly to the outside during installation of finishes and other VOC emitting materials. 3. Check that the maximum outside air ventilation rate does not exceed heating, cooling, and humidity levels.
