Event Details

This focus of this unit is techniques for assessing the energy efficiency of existing dwellings, and for identifying and evaluating improvement options. The range of energy use in dwellings is reviewed, emphasising that every dwelling is unique.

The theoretical basis and key features of the Standard Assessment Procedure (SAP) energy rating are explained. Derivatives such as Reduced Data SAP (RDSAP) which provides the basis of Energy Performance Certificates, and the supplementary occupancy assessment for Green Deal Assessments, are also explained.

The training, certification, registration and quality assurance arrangements for Domestic Energy Assessors and Green Deal Assessors are briefly reviewed. Going beyond SAP, the unit considers the other information needed for an assessment: the site constraints and planning context; the construction type; the condition and need for repairs; the occupants’ or landlord’s objectives, constraints and budget; and the opportunities for other improvements alongside retrofit.

Procedures for comparative evaluation of improvement options are reviewed, including simple-payback analyses, ECO scores (emissions savings) and ‘carbon cost effectiveness’. Examples are provided of how improvement option evaluations may be presented.
