This enables a result for specific space heat demand to be calculated quickly using default values, potentially saving significant time. (designph.org)
For instance they make different assumptions about thermal comfort levels, and this profoundly effects the assumptions about space heating demand. (passivehouseplus.ie)
This involves ensuring the individual components of the building fabric and ventilation system are certified, rather than aiming for an overall space heating demand figure. (passivehouseplus.ie)
