What 1are Nearly Zero Energy Buildings?

Nearly Zero Energy Buildings are defined in the Energy Performance in Buildings Directive (EPBD) as “a very high energy performance… The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby”. 

How is it being implemented?

Nearly Zero Energy Buildings is being implemented through Part L of the Building Regulations.

Part L for Buildings Other than Dwellings was published in December 2017, and applies to all new buildings commencing after the 1st January 2019. The regulations require a 60% energy performance improvement on the previous building regulations. This typically corresponds to an A3 Building Energy Rating. This means an improved energy performance for the fabric, services and lighting specification. It also introduces a mandatory requirement for renewable sources, which must in general provide 20% of the primary energy use. However, there is flexibility where the building is more energy efficient than the regulations.
