Indian Hills Residence – Net Zero Home, Solar Thermal, Variable Volume Heat Recovery, Radiant heat, and Air Coils
Mechanical design for a new net zero energy residence. Systems include solar thermal heating (domestic hot water, space heat), interface with PV solar, energy recovery, variable speed main fan system, radiant floor heating, sun-space heat transfer. Low-energy fan system distributes solar heat and heat transferred from the sun space through variable volume, multiple zone system. Selected areas have radiant floor heat. Spread sheet-based energy analyses used to optimize thermal mass (double 5/8 drywall) and solar hot water storage. Computer modeling of solar thermal. Solar thermal system uses evacuated tube solar collectors for high efficiency. Detailed computerized load calculations optimize heat distribution.
