data collection overview for an epc
Start
INTRODUCTION
When producing an EPC, the DEA carries out a non-intrusive property survey to collect the information required for the RdSAP software to calculate the energy efficiency rating. We'll take a deeper dive into this information as the course progresses, so here we'll just provide an overview of some of the key elements.

Property details
Dimensions and layout
Construction elements
Heating and hot water
Ventilation and lighting
Renewable technologies
Evidence
RdSAP Conventions impose specific rules about what constitutes acceptable documentary evidence. (Convention 9.02)
Assumptions
Where certain details are not visible, RdSAP makes assumptions about things like levels of insulation, based on the age of the property. It also assumes things like occupancy and heating patterns.
Activity completed
Property details
The DEA records general information about the dwelling, including address, property type (e.g. house, flat, bungalow), age, construction type, orientation, and whether it is a detached, semi-detached, or terraced property.
Renewable technologies
Any renewable technologies are identified, such as solar photovoltaic panels, solar thermal systems, heat pumps, or wind turbines.
Ventilation and lighting
Ventilation features include extract fans, chimneys, flues, open fireplaces, and any mechanical ventilation systems. Lighting consists of the number and type of light bulbs (e.g. LED, CFL)
Dimensions and layout
Measurements are taken to determine the total floor area, room heights, heat-loss perimeter and window areas. You'll identify the number of storeys, whether there is a roof room. The number of heated and unheated habitable rooms is required too.
Construction elements
Details of walls, roof, floors, windows, and doors are gathered, including construction type, insulation levels (where visible or evidenced), glazing type, frame material, and draught-proofing.
Heating and hot water systems
- Heating system(s) (e.g., boiler, heat pump, storage heaters),
- Fuel type (e.g., gas or electricity)
- Heating controls (e.g, thermostat)
- Heat distribution (radiators/ underfloor),
- Secondary heating
- Hot water production and storage.
