The Nordic Built “Active Roofs and Facades” project, coordinated byCenergia, has received support from Nordic Innovation, EUDP (DK),Energimyndigheten (SE) and Rannis (IS) allowing strong developmentof leading Nordic competences in the area of building renovation.
This is achieved by the creation of transnational Public PrivatePartnership models to support the development of nearly zero energybuilding solutions and associated performance documentation – whichis required in the EU building directive.
The proposed cooperation with the building industry on developingmodels and the demonstration of “Active House” based sustainablerenovation is creating a strong Nordic alliance.
The project runs from 2014 to 2017 and involves companies which arerepresented in the Nordic countries and companies from theinternational Active House Alliance (www.activehouse.info). Thedevelopment will use the best transnational competences and networks,creating greater possibilities to export technology.

UnifilterAs an option, EcoVent RT300 can be supplied by our patented Unifilterwhere there is a plug & play module.
M5 is the standard filter class, but other filter classes are available on request.
UNIFILTER consist of two coils between which the filter medium passes overthe smooth rollers, forming a bag filter with 15 in the bags. One reel containsnew filters while the other coil is used to roll up the used filters – enough for10 to 15 years of operation.
The coils are placed in closed cylinders which separates the pure and theused filter from the air stream. When the control system informs the coilmotor a new filter will be fed.
The control system also notifies the user of the remaining life of the filter.
