Structural Insulated Panel Systems - SIPs are per-fabricated panels which sandwich a thick layer of foam insulation between sheets of OSB (oriented strand board). Not only do SIPs have a high R-value, but, because they are glued together, they create a seamless insulation enveplope. The Meadow has 6" -thick, R-23 wall panels, and 10" -thick, R-38 ceiling panels. SIPs buildings are extremely quiet and air-tight. Because they are engineered for structural strength, SIPs eliminate wall studs and roof rafters. Roof panels have the strength to span greater lengths than comparable roof rafters.
Solar Photovoltaic Energy - A 2.244 Kilowatt solar panel array, located on the south side of the garage roof, will produce almost as much electricity as each home consumes. Using a net-metering system, when more electricity is produced than is consumed, the electricity is fed back into the grid. The meter actually runs backwards, so the homeowner is only billed for their net electricity consumption.
Maintaining Air Quality in a Tight Home - in an airtight, highly insulated building, it is crucial to have good air treatment and circulation without losing valuable warm or cool air. An air-exchanger is a vital component of the HVAC system which brings fresh air in from the outside of the thermal envelope, and exchanges the heat from the outgoing air into the inoming fresh air. The HVAC system also includes special air filtration and ultra-violet treatment for dust, bacteria, pollen, and spores.
Comprehensive Insulation Techniques - Exterior foundation rigid insulation, foam insulation around sill plates and building openings, and continuous ceiling insulation combine to create a virtually leak-free thermal envelope.
Low VOCs - VOCs (Volatile Organic Chemicals) are used as litle as possible in an an almost airtight, green home. Cabinets, paint, sealers, and adhesives are either no or low VOC content.
Renewable Materials - Renewable Materials are used throughout the home including bamboo floors and recycled content carpet.
Testing for LEED Certification - Extensive plan review, product and process documentation, inspections, and testing are required for LEED certification. Duct air-blast tests insure that air ducting is as efficient as possible, and a whole-house blower test insures that the home is virtually airtight.
Super Efficient Heating and Air-Conditioning - The HVAC system includes energy efficiency blowers, furnace, and cooling. Using a 95% efficient furnace and a centrally located tankless hot water heater reduces natural gas consumption to a minimum. While the high efficiency AC (14 SEER) and blowers, combind with the photovoltaic solar collection will result in extremely small net electric usage and cost.
