Explaining RdSAP

Stroma Software’s EPC & OA module is based on RdSAP methodology, for compliance with Governmental requirements.

The Reduced Data Standard Assessment Procedure (RdSAP) was developed by the Government for use in assessing existing dwellings. RdSAP is a system of property data collection, together with defaults and inference procedures, that generates a complete set of input data for calculation. To enable the energy ratings of properties to be fairly compared, RdSAP has been designed to assess the building rather than its occupants. This means that individual household behaviour is irrelevant and an Occupancy Assessment (OA) is required to assess behavioural factors for a full Green Deal Assessment.

RdSAP makes the following behavioural assumptions:

  • Standard occupancy – the size of the dwelling determines the number of occupants and therefore the hot water requirement.
  • Standard heating pattern – the heating requirement is based on the volume of the dwelling, following standard heating patterns of 9 hours heating a day during the week and 16 hours a day at the weekend. The living area is heated to 21°C and the rest of the house to 18°C.

The EPC Module additionally draws information from databases within the Product Characteristic Data File (PCDF), a regularly-maintained database through which certified Energy Assessors can locate appropriately-calculated seasonal efficiencies and characteristics for heating and related products; this therefore reduces the risk of miscalculation and confusion with data.

OA calculations

The software simplifies the assessment, calculation and lodgement process for Occupancy Assessments. The Occupancy Assessment (OA) software module within Tracker Mobile will cover all calculation requirements required for a domestic Green Deal assessment:

  • Predict the energy demands of the household, based on the occupants' behavioural patterns and the energy appliances used. These energy demands are then adjusted to account for the actual bill history. Some forms of bill history are more accurate than others, and therefore the software makes a further adjustment based on the type of bill history provided.
  • Calculate the predicted cost of installation, and household energy savings, for each measure identified in the EPC. A regularly updated Product Characteristic Data File (PCDF) is used to determine the key factors for these calculations. In-Use Factors are then applied for each measure, effectively reducing the amount of Green Deal finance that can be offered for each measure, by a set percentage. Their purpose is to account for likely differences between the measure's performance in-situ and under controlled conditions (for example, due to imperfect installation or inappropriate use). In-Use Factors are determined by the Department of Energy and Climate Change (DECC) and revised every 6 months; the OA software accounts for this.
  • Determine which energy efficiency measures will qualify for Green Deal finance, in full or in part. To qualify, the financial savings of the measure must be greater than the loan repayment. This is known as the Golden Rule.
  • The OA provides a fully comprehensive set of calculations, which are able to specify, which energy efficiency measures are suitable for any given home in the UK.

The Occupancy Assessment is lodged alongside the EPC, together forming a Green Deal Advisory Report for the property.
