Accredited Construction Details (ACD’s) have been developed to assist the construction industry achieve the performance standards required to demonstrate compliance with the energy efficiency requirements (Part F Northern Ireland / Part L England) of the Building Regulations.
They focus on the issues of insulation continuity (minimising cold bridging) and airtightness. They are not intended to provide any detailed guidance on other performance aspects such as vapour control, ventilation, etc which must also be considered by the design and construction team.
The details contain checklists which should be used by the Designer, Constructor and Building Control Body to demonstrate compliance.
