7 nzeb Definition DEFINITION Nearly Zero Energy Building Means a building that has a very high energy performance Nearly or very low energy amount should be covered to a very significant extent by energy from renewable sources, including renewable energy produced on-site or nearby Presently no common definition of nzeb, neither in policy nor in the market Timeline ofepbd recastfornzebs source: Atanasiu

8 State oftheart-nzeb Definition Principle of Nearly Zero Energy Buildings (NZEBs) renewable energy generation weighted energy supply energy efficiency passive approaches weighted energy consumption modified from Sartori et al. Items for a consistent definition Building system boundary Physical boundary Balance boundary Weighting system Metrics Symmetry Time dependent weighting Net ZEB Balance Balancing period Type of balance Energy efficiency Energy supply Temporal energy match characteristic Load mismatch Grid interaction Measurement and verification 8

9 nzeb definition and rating by CEN CEN draft standard for nzeb rating on-site energy production refers to on the building or building parcel => unique and strong link to the building nearby energy source refers to a dedicated connection to the building requiring specific equipment Renewable energy ratio (RER) is the ratio of renewable to non renewable primary energy CEN nzeb rating procedure source: Zirngibl

10 NZEB Definition and policy strategies North-America Definition Net Zero Energy Building No one universally accepted definition in US Working definition widely used is building that generates as much energy on site as it buys from utilities on annual basis DOE Buildings Technology Office Strategic Focus Maximize energy efficiency of US buildings Reduce building energy consumption by 50% vs levels by 2030 Sub goal for HVAC 20% reduction by 2030 Sub goal for WH 60% reduction by 2030 No specific NZEB goal but maximizing building performance will minimize on-site renewable energy resource needed to achieve NZE (or plus energy) performance level Canada ASHRAE Target: All new buildings NZEB by 2030 source: Payne Annex 40 workshop, IEA HPC
