Design to use less energy
Cosgraves first priority is to create homes that require less energy to operate. Investing in improvements to the fabric of the house the energy requirement is minimised, products and systems are installed to reduce energy waste and finally energy is recycled, particularly from the warm air leaving the house. The Photovoltaic Solar Panels then supply some of the reduced energy need decreasing even further the draw on the grid.
Highly insulated air-tight design
The passive house principles adopted by Cosgraves improve comfort while reducing the energy demand of the house. Superior insulation, increased levels of air-tightness, improved Low E argon filled windows and careful detailing to cut out thermal bridging combine to contribute to both reduced heat loss and solar gain.
Using a Heat Recovery Ventilation system Cosgraves use 90% of the heat energy that would otherwise be lost to the home while maintaining a constant flow of fresh air to the house and significantly reducing utility costs.
Reduced draw on grid
Having primarily reduced the energy requirement by maximising energy efficiencies and minimising wasted energy, Cosgraves then introduce features to more efficiently supply the reduced need, including an “A-Rated” condensing boiler unit and Photovoltaic Solar Panel system.
