We deal with the first third by way of extra insulation in the external walls, the ground floor, the roof and superior A rated double glazed windows.
We deal with the second third, which is of equal importance as the first third, by making the house much more airtight and then delivering fresh air by way of an efficient Heat Recovery Ventilation system. With the unique NuTech Integrated system we also feed energy from the solar collectors into the HRV system thereby delivering warmed air to the house. This reduces the Energy Demand of the house even further. It also increases the amount of Renewable Energy delivered to the house which means that the Renewable Energy Demand of 10kWh/m2 per year, as demanded by the Building Regulations, can be met by this system.
