Energy reporting requires an understanding of both the building envelope and the building services within the envelope. It is therefore fundamental to any energy survey or reporting that the buildings services are considered.

The relevant scope and detail required in each of the above reports may vary dependent on building or development type, the stage of the project, planning policy requirements and client needs.

Mechanical and electrical services design and assessment can therefore be included in any project brief as required. Mechanical and electrical services can therefore include the following:

• Outline building services strategy
• District Energy network assessment and design planning
• Design feasibility and spatial strategy requirements
• Renewable technology integration
• Building services performance specification
• Building services detail design and specification
• Building energy simulation modelling using approved software
• Site survey and inspection reports

It is important to establish the client requirements at the outset to ensure the correct brief is agreed to ensure the correct service level is provided to meet the client goals at the appropriate project stage.
