Good Homes Alliance and Woodknowledge Wales commissioned an energy modelling report to compare different low energy building standards. The paper seeks to illustrate how the choice of a building standard affects the amount of renewable energy generation that is required to comply with a net zero operational outcome. The report does not take into account embodied energy/carbon. All energy and carbon modelling is illustrative but based upon real archetypes.
The work was carried out by John Palmer of the Passivhaus Trust in August 2020.
The report can be down loaded here.
