Overview

Part O is concerned with reducing overheating risk in new residential buildings. The appropriate assessment route depends on the project. Early review is valuable because glazing, orientation, shading, purge ventilation, openings and constraints such as security or noise are architectural decisions, not late-stage calculation inputs.

Good to know

Project requirements vary by building type, location and timing. Send us the project information and we will confirm the right assessment route before providing a quotation.

Particularly useful for

  • New dwellings at concept or developed-design stage
  • Projects with large or concentrated glazing
  • Sites where open windows may be constrained
  • Design teams comparing shading or ventilation options
