Regulation 25A

Regulation 25A is a new regulation that has been introduced concerning the construction of new buildings and is needed in 2017. Before the construction of a new building starts, the developer should carry out an in depth analysis in order to determine the environmental, technical and economic feasability of using high efficiency alternative systems.

A report should be produced to show whether any of the following could be included, while still being able to make the project cost effective, environmentally sound and technically feasible:

  • Cogeneration (combined heat and power)
  • District heating or cooling
  • Heat Pumps
  • Decentralised energy supply systems based on energy from renewable sources

The developer must give the building control body (BCB) a notice to confirm that it has been undertaken and well documented. Furthermore, there is no requirement to install these systems once the report has been completed, if the target emission rates can be achieved in another way.

Regulation 25A came into effect on 9th July 2013. It is important to note that this regulation applies to all work submitted after that date. However, projects are exempt from the regulation if they: Commenced work before 9th July 2013 – Served an initial notice on or before 8th July 2013 and work commenced onsite on or before 9th.
