The aim of the guideline is to support, in a practical way, a design process for realizing Nearly-Zero Energy Buildings (NZEB) in the context of Mediterranean-climate, focusing more on the mechanical systems than on the building envelope, which has previously been treated in Part 1 (REHVA Guidebook No. 28).
This guidebook shows three nZEB buildings of different uses: office, locker room and single-family house. The three real cases are analyzed for different climatic zones, where different alternatives for the design of the building and its facilities are presented.
This guidebook aims to build a bridge between the real estate community and the engineering community. It explains the challenges of property valuation based on real data and how the sustainability and HVAC-technology can have an impact on value.
