Warwick Buildings and Energy Committee Draft Meeting Minutes: March 25, 2011 Location: Warwick Town Hall Meeting called to order 6:36 Attending: Janice Kurkoski, Steve Kurkoski, Jim Toth, Jack Cadwell, Dan Dibble, Les Goodman, Keith Abbott Minutes for February have been accepted. TOWN HALL Window restoration - David has awarded the Phase 2 contract to install storm windows at the Town Hall to Carbone of Keene. WARWICK COMMUNITY SCHOOL Keith Abbott explaining the Audit Report - Doing estimations with an existing structure can be tricky because when the building is taken apart for work some unforeseen issues may arise. Warwick should be careful of contractors that submit bids for the work that are extremely low. The job cannot be done by a small contractor. They do not have the type of equipment that is needed. The audit should be given to contractors without the cost estimates. A good place to look for contractors in this area can be found at BPI.org. A BPI accredited company will have all of its work accredited. A certified BPI contractor may only have one individual certified. In the future when we are selecting a contractor we can share the proposed envelope improvement information with Keith and he will let us know what the payback period will be. The energy modeling programs that were used were the best available at this time. The programs give an estimate of savings. Savings and payback periods were calculated at $2.80 per gallon oil. The existing heat exchanger units can heat or cool the building. The school does not use this system to cool the building. There are three units that deliver fresh air but according to the modeling only one is needed. The problem is that these same three units also deliver the heat and run all the time. When the building is improved with air sealing and insulation these units will run less than 24 hours a day. The boiler runs in the summer for hot water, but this is a very small issue compared to others. The envelope improvements are a standalone issue. Do the envelope improvements first and if a new heating and distribution systems are installed they should be sized on the BTU required not on the building size. The stack pipe for the boilers that goes through the ceiling needs to have the clearance-to-wood members addressed. This is a safety issue. Unless the boilers are configured in a "B-vent" pattern, then there should be 6" clearance to the nearest flammable material. The office equipment and the computer room phantom loads need to be addressed right away. A master switch or "smart strips" should be used for all items in the computer lab, library, and offices. The 'power options' settings on all computers should be set to go off (or to sleep) after a short period of disuse. The gym roof probably gets too hot and may be attributing to the premature failure of the shingles. While we are putting on a new roof this is the time to put on extra insulation over the existing sheathing. Venting would be built under the new sheathing if shingles are used, or directly under metal. A metal roof on the gym and stage may be a good option, but may drop dangerous amounts of snow and ice. This situation can be addressed with roof ice cleats. If option A is used in the main building, the sprayed foam that is specified to be installed against the "Accu-Vents" may need to be covered with a fire retardant. In the attic, the upper corridor ceiling corners do not touch the rafters. The Gill school is in the process of having energy conservation work done. They have worked out an agreement with the Montague School District addressing what the financial arrangement will be. Janice will make a spread sheet about the report options.
