Combining construction experience with scientific knowledge

Thermal imaging

We use a thermal imaging camera to assess the thermal anomalies of the building envelope. The scan exhibits temperature variations converting data into a visual image that colorizes heat, making it quick and easy to identify thermal variance.

Bioclimatic architecture

Bioclimatic architecture is a way of designing buildings based on the local climate, to ensure thermal comfort using environmental resources. They must also blend into their natural surroundings. The orientation, size, height, layout, and even the colour of these houses are planned before they are built to make the best use of energy.

Mechanical services

A low energy mechanical heat recovery system fitted with air filters ensures the constant renewal of high quality airflow throughout the building. From a health point of view, the quality of the circulating air and the ventilation system eliminates all internal dampness and ensures a healthier environment for anyone suffering from asthmatic conditions.

EnerPHit renovation

The challenge in step by step energy renovation is to reach an optimal energy efficiency standard for the whole building after completion of all individual retrofit steps. To reach this aim, all steps need to follow a common master plan. A well thought out master plan is not only indispensable for a good final result, but it also helps keep the overall cost low. Costly alteration works because of a shirt sighted earlier measure can be avoided and energy costs are gradually reduced to a minimum.


To achieve Passive House certification the building must pass an airtightness test, which is designed to check for air leaks in walls, attics, and mechanical penetrations. While a blower door test does not evaluate how well a structure is insulated, it can reveal drafty walls and air-bypass situations that could undermine otherwise well insulated wall assemblies. Passive House has the most stringent blower door test requirements, allowing a maximum air infiltration of 0.6 changes per hour at 50 Pa pressure difference.


To achieve Passive House certification, a building must demonstrate:

  • Heating and cooling demand <15kWh/m2 per year.
  • Primary energy demand <120kWh/m2.
  • Electricity demand <0.45Wh/m3.
  • Building airtightness <0.6/h
  • Ventilation with >75% heat recovery
  • Excess temperature frequency (25oC) <10% of hours in the year above 25oC.
