Energy efficiency

Building energy efficient homes for the future

The Svenskhomes system uses fundamental thermal performance and air-tight construction principles to build highly energy efficient homes. This fabric first approach means our homes achieve optimal energy efficiency with minimal need to install expensive renewable technologies.

Our building system has been tried and tested to withstand the extremes of the Scandinavian climate. This provides the perfect building envelope by using a highly insulated wall design (minimum of 240mm insulation) along with a high performing sarked roof structure (minimum of 295mm insulation) and premium quality Scandinavian triple glazed windows and doors.

Performance U-Values

  • Walls – 0.16, 0.14 or 0.122 W/m²K (subject to chosen wall specification)
  • Roof – 0.13 W/m²K minimum.
  • Triple glazed windows inc fixed windows – 1.0 – 0.8W/m²K
  • Doors – 1.2 W/m²K minimum.

(U-Value is the measurement of the rate of heat loss through a material. Ideally in all aspects of home design you should strive for the lowest U Values possible because the lower the U Value, the less heat will be needlessly escaping).


Air-tight construction techniques are essential when building energy efficient homes to prevent unnecessary draughts and heat loss. Our homes typically achieve an air test performance of 2-3 mᶾ/(h.m²) @50 Pascal’s.

We also concentrate on eliminating thermal bridging in the design stage providing the best level of energy performance. Thermal bridges occur at junctions; for instance where walls meet, or where a wall meets a floor or a wall meets a roof, window or door.

Your Svenskhome can achieve an A-Rated EPC with the simple inclusion of:

3 kW of Solar Photo Voltaic (PV)

A wood burner

A 90% energy efficient gas or oil boiler
