Calculation tools for Part L 2013Paul DavidsonDirector, Sustainable Energy8th October 2013
– Changes to calculation engines
– Implementation of compliance rules
– SAP
– SBEM
– New technologies and products
SAP and SBEM
SAP 2012
– Updated from SAP 2009
– Consultation completed in 2012
– Published May 2013
– Minor improvements to calculations and assumptions
– Changes to emission factors
– Details at www.bre.co.uk/sap2012
SAP 2012 – key changes from 2009
– Updated fuel prices, primary energy and CO2 factors
– Use of regional weather for wind speed and solar radiation
– Updated calculation for solar radiation
– Controls for heating and hot water systems with boilers
– Options for party wall heat loss
– Insulation of primary pipework
– Additional options for storage heaters
– Default seasonal performance of heat pumps (and MCS credit)
– Low temperature heat emitters
– Full specification, plus detailed technical papers, at www.bre.co.uk/sap2012
SAP Appendix R
– Contains parameters required to model Notional Building
– For CO2 target (TER)
– And target fabric energy efficiency (TFEE)
– To be published shortly, as an updated full SAP document
– Applies to England only for now
– Other country versions to follow
Temporary SAP software– Based on cSAP (produced for consultation)
– Implements SAP 2012– Pending development and approval of commercial tools
– Derives the TER and TFEE according to new Appendix R and ADL1A
– Will allow housebuilders and industry to explore new requirements and test new designs and products
– CANNOT be used to demonstrate compliance
– Available in November from www.2013ncm.bre.co.uk
– Pilot version to be demonstrated at lunchtime
cSAP for 2013 trials
Part L compliance report (BRUKL) - extract
SBEM – current ‘live’ version v4.1.e
SBEM – recent changes
– Default lighting efficacies for temporary buildings
– Minor changes to Activity data
– Enhanced Output Report
– Modified auxiliary energy
– Enhancements to iSBEM interface
– Requirements of EPBD recast– Primary energy report– Consideration of ‘alternative energy systems’
– Revised treatment of metal clad construction (‘sheds’)
– Green Deal tool also available at www.gdtool.bre.co.uk
‘Alternative energy systems’
SBEM 2013 – v5.2.a– Based on v 4.1.e , with improvements
– Improved treatment of shading devices– Improved handling of PV systems– Non-transpired solar collectors– Enhanced reporting on Criterion 2 compliance
– New category of Notional Building, based on daylight– Side-lit, heated only– Side-lit, heated and cooled– Top-lit– Un-lit
– New concurrent Notional Building definitions as per NCM and ADL2A
– CANNOT yet be used to demonstrate compliance
– Available shortly, from www.2013ncm.bre.co.uk
SBEM outputs
Other SBEM issues
– Updated NCM Modelling Guide to be released soon
– Specifications for DSM and alternative interface software
– New version will include Green Deal tool
– And live EPCs for Scotland
– Final, full version for April 2014
