Leaders in Energy EfficiencyGuided by Passive House principles, Cosgrave houses are designed to use less energ y, the team’s commitment to energy efficiency and sustainable design is recognised at the highest national level.
Pioneers of the green agenda, Cosgraves continue to develop homes that exceed the requirements of regulations. The energy efficiency of a Cosgrave home cannot be measured just by a BER Rating, it is deeper than that, it is in every detail of the fabric of the building and is validated through a series of quality control measures that ensure every Cosgrave built house really is a superior energy efficient home.
Guided by Passive House Principles the Team at Cosgraves invest in the fabric of the house to ensure it delivers sustainable living in terms of lower energy usage, improved comfort and reduced life time running costs.
In 2013, Cosgraves were recognised as the best of the best when the Sustainable Energy Authority of Ireland awarded them the Overall Environment Award for outstanding leadership in the field of energy efficiency. This is a very significant achievement as the award is open to all sectors and has never before been awarded to a house builder and is a highly valued endorsement of Cosgrave’s higher standards in energy efficiency.
The Four Pillars of Cosgrave Energy Efficiency
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.
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 some features to more efficiently supply the reduced need, including an “A-Rated” condensing boiler unit and Photovoltaic Solar Panel system which is fitted with a Warik EnergyMiser unit to ensure the energy that is created in the house is used in the house and not lost to the grid.
