Summer Day Energy Flow

Energy flow diagram of Harmony during a Summer day

1) Wind blowing over aero cap causes negative pressure at top of wind tower drawing warm air out of home 2) Velux electrically operated opening skylight allows warm air to escape when cooling is required automatically closes if it rains 3) High insulation lelvels reduce solar heat gain through roof during summer 4) Sunlight falling on photovoltaic (solar electric) panels converted to eletricity and fed into the electrical grid
5) Sunlight falling on Thermo Dynamics solar thermal collectors heats working fluid which transfers heat to 454 liter 6) Cooler outdoor air drawn in through opening windows on second floor 7)Warm air drawn from room through internal opening skylight 8)Warm air rises by stack effect
9) SUnlight falling on photovoltaic (solar elctric) panels converted to electricity adn fed into the electrical grid 10) Overhangs over south facing windows reduce solar gain during summer 11) Air flow provides a cooling effect while introducing cooler air and removing warmer air from house 12)Cooler outdor air drawn in trhough opening windows on main floor and basement
13) 454 liter (120 gallo) super insulated solar hot water storage tank. Heat transfered from working fluid to tank by way of Thermo Dynamics Solar Boiler
