Upgrading of the non-residential building stock towards nZEB standard: Recommendations to authorities and construction industry

A few exemplary non-residential renovation projects have demonstrated that total primary energy consumption can be drastically reduced, together with improvements to indoor environment quality through renovation of a building’s passive and active systems. Because most property owners are not even aware that such savings are possible, they tend to set less ambitious targets. Buildings that are renovated to mediocre performance can be a lost opportunity for decades.
The objectives of IEA SHC Task 47 are to develop a solid knowledge-base including: how to renovate non-residential buildings towards the Net Zero Energy Building standards NZEB in a sustainable and cost efficient way; ways to identify important market and policy issues; and effective marketing strategies for such renovations.
This report describes the work of Subtask B, which covers market and policy issues and marketing strategies for deep renovation of non-residential buildings.
