Nearly Zero-Energy Buildings and Offsite Renewables | Leonardo ENERGY

The facts and thoughts presented in this position paper reveal the complexity but also the potential organisational, financial and environmental benefits of integrating off-site electricity into the nearly-zero energy building concept. A thorough analysis of the EPBD's definition, existing concepts for nZEBs, aspects that influence the share of renewable energy and key issues around off-site renewables in nZEBs like energy cost, the advent of grid parity, metering schemes, ownership schemes of electricity generation, standardisation, monitoring, verification and enforcement has been done as a first contribution for starting a broader discussion around this topic.

Duane Tilden's insight:

Although nearly-zero energy building standards will be mandatory only for new buildings by 2020 the next and even more important question is how to transform the building stock to that level until 2050. The sheer magnitude of this challenge requires that in principle every building owner must be given a sufficient set of options to have a fair and equal chance to transform his property to nearly-zero energy standard. Thus electricity from on-site, nearby and off-site sources must be a natural part of the set of options.

The potential contribution from solar shading has been underestimated, despite the widely recognised fact that avoiding overheating reduces cooling demand.
Undoubtedly, much of the work starts at design stage. BUILD UP has a wealth of resources on this subject.
