The winner of each of seven separate categories in this Europe-wide award will win a trip to Japan and there are prizes for other entries.
The judges will be looking for the projects which demonstrate the most flair and innovation, as well as showcasing sustainable design, efficiency, cost effectiveness and aesthetics.
There are seven categories covering both residential (single dwelling, multi-dwelling and social housing) and commercial projects (best air conditioning project and best hotel, retail and restaurant project).
The judging panel, including Angela Brady, president of the Royal Institute of British Architects, will be drawn from the fields of architecture, building services as well as the heating/cooling industry.
Projects from across Europe are eligible and must have been completed between January 1, 2012, and July 31, 2014. Deadline for entry is July 31, 2014 and winners will be announced in the Autumn.
