Clean Energy Technology

Prefabrication refers to the assembly of structural building components in a controlled environment outside of the construction site. The assembled structure is then transported on site to be finalised.

Window with R-values of R-5/7 achievable thanks to low emissivity coating, multi-panel, well insulated and sealed glazing assemblies, and low conductivity frames.

Systematic sealing of air leakages throughout the building surface (and particularly around cracks, small holes, plumbing, wiring, lighting and ductwork) to reduce heat loss and better control humidity. This needs to be coupled with appropriate ventilation. Technologies: foam, caulk, tape or gaskets.

Multi-functional energy facade that receives the solar irradiation and converts it into heat energy for the heating/cooling circuits.

Passive modification of properties in terms of thermal transmittance, solar heat gains coefficient and visible transmittance due to a change in temperature.

Low emissivity film directly applied in the interior side of windows or to the external window frame to allow or prevent heat gains depending on building energy needs.

Achieving a thermal and humidity transfer in heat recovery ventilators by preconditioning the ventilation air in a modular system (while state-of-the art energy recovery ventilators offer low humidity exchange).

Multiple layers of air and glazing where the air cavity is ventilated (naturally or mechanically).

Window able to change transmittance, solar heat gain coefficient and visible transmittance, energised by electrical current.

Insulation made with synthetic porous material in which the liquid component of the gel is replaced with gas (aerogel). They can also be used as transparent insulation materials.

Phase-change materials provide latent heat storage (i.e. at a constant temperature, by changing the material's phase) and are integrated into different building components. They enhance the building's thermal performance as heat losses are reduced. Integration: in concrete, glazing, between structural elements, using insulation wallboards or even combined with building-integrated photovoltaic (BIPV).

Changing envelope functionality in response to the variation of climate conditions and occupant behaviour, using controllable thermal mass, ventilation, shading, heat exchanges, humidity control, etc.
