Windows – making it clear: energy, daylight and thermal comfort (NF78)

Share this Post:

This guide, released by the National House Building Council (NHBC) Foundation, presents the impact of window choice on energy performance for a range of typical home types (mid-floor apartment, mid-terrace house, semi-detached house, detached house). The guidance is developed from modelling results using the Passivhaus Planning Package (PHPP).

 

The document shows how glazing type, frame width, overall window area and orientation affect performance and provides graphics and design aids to help housing designers address particular objectives and to identify quickly and economically where the most promising solutions lie. The guide aims to help housing designers to understand the implications of their design decisions, and to make informed choices based on whether the objective is to achieve lower space heating costs, reduced overheating risk or maximum daylighting.
