Domestic and non-domestic energy performance certificates: review

BEIS

Business, Energy and Industrial Strategy (a UK government Department)

BREDEM

Building Research Establishment’s Domestic Energy Model (underpinning methodology of SAP and RdSAP)

DEA

Domestic Energy Assessors (approved assessors in England and Wales for carrying out EPC assessments for existing dwellings)

DECs

Display Energy Certificates (operational ratings required on some non-domestic buildings)

ECO

Energy Company Obligation that ran from 2013 to 2015

ECO2

Energy Company Obligation that ran from 2015 to 2017

EES

Energy Efficienct Scotland (the long term Scottish Government strategy launched in 2018 to raise the energy efficiency standards of Scotland)

EESSH

Energy Efficiency Standard for Social Housing (the Scottish registered social landlord obligation to meet specified energy efficiency standards within their respective dwelling stocks by 2020)

EPBD

Energy Performance of Building Directive (the initial directive under this banner in 2002 initiated the requirement for EPCs on buildings when they were constructed, sold or rented. Subsequently updated and revised.)

EPCs

Energy Performance Certificates

EST

Energy Saving Trust (amongst many other activities, responsible for managing the Scottish EPC register)

EU

European Union (responsible for introducing the EPBD)

HEED

Home Energy Efficiency Database (a database owned and managed by the EST of energy efficiency installations and other housing-related data they have collated through their activities)

HEEPS ABS

Home Energy Efficiency Programme for Scotland: Area Based Scheme

LHEES

Heat and Energy Efficiency Strategies, and Regulation of District Heating consultation document (published by the Scottish Government in 2017, the published responses to which were one of the three source data sets used for this report)

MHCLG

Ministry of Housing, Communities and Local Government (a UK government ministry)

NCM

the National Calculation Methodology (the underpinning methodology for assessing the energy performance of new and existing non-domestic buildings in the UK)

PCDB

Product Characteristic Database (the database of a wide variety of energy performance related factors that underpin the SAP and RdSAP calculation models)

PRS

Energy Efficiency and Condition Standards in Private Rented Housing consultation (published by the Scottish Government in 2017, the published responses to which were one of the three sources of data sets used for this report)

RdSAP

Reduced Data Standard Assessment Procedure (the UK approved methodology for assessing the energy performance of existing dwellings for the production of EPCs. In effect, it is a subset of SAP)

RHI

Renewable Heat Incentive (a grant for funding renewable heating, available for both domestic and non-domestic buildings)

SAP

Standard Assessment Procedure (the approved UK methodology for assessing the energy performance of buildings for EPCs and Building Regulations)

SBEM

Simplified Building Energy Model (a calculation model that uses the NCM to assess the energy performance of non-domestic buildings for the production of EPCs). This includes Dynamic Simulation Modelling (DSM) software tools

SEEP

Scotland’s Energy Efficiency Programme consultation document (published by the Scottish Government in 2017, the published responses to which were one of the three source data sets used for this report). SEEP was the precursor to EES (see above).

SERT

Scottish Energy Rating Tool (the initial model proposed for the production of EPCs in dwellings in Scotland. Superceded by RdSAP)
