Consider a new passive or energy-efficient property

Passive construction: helping you to plan your works

Designing and building a passive construction or property with a high energy performance require meticulous planning. The shape of the building, its orientation, sealing the envelope and calculating energy requirements are key points which should be studied closely.

energieagence, a subsidiary of Enovos, will provide effective support in the construction of your future passive or HEP home as regards compliance with the latest ecological construction standards.

Financial and technical aid for passive construction

Enovos and energieagence want to guide you through every stage of your passive construction: from planning the works through to obtaining state aid and creating your energy passport to obtain a building permit.

This is why Enovos and energieagence will guide you in your choices, especially with regard to the building envelope. Thermal insulation is the key component in the design of a passive construction or high energy performance building. The higher the quality of the insulation, the more simple and economical the technical installations.

In low-energy and passive houses, it is vital to install a controlled ventilation system with heat recovery (at least 80%). This system guarantees a pleasant indoor climate and significantly reduces heat loss compared to window ventilation.

Calculation of thermal bridges and the "blower-door" test

energieagence will help you to calculate thermal bridges according to the type of wall construction. This approach can reduce the influence of the thermal bridges taken into consideration (3% fixed since 2017) in calculating the energy passport.

A "blower-door" test should be carried out to ensure that the building envelope is air-tight. Air leaks can be detected and rectified using a thermal camera and a blower system. The degree of sealing achieved will be certified.
