Using EDSL Tas we can provide the evidence for several of significant BREEAM credits including:

ENE01 – Carbon Emissions
HEA 01 – Visual Comfort Daylighting,
HEA03 – Thermal Comfort (including Summertime Overheating Assessments),
ENE04 – Low Carbon Feasibility Studies

Our consultants can also advise as to the best methods of improving credits.


Providing calculations demonstrating compliance with Part L2 BERvTER. Latest Regulations have made the requirement for early assessments more critical.

We also provide EPCs up to level 5 using DSM (Dynamic Simulation) methodology.


With considerable experience in advising on methodologies for gaining BREEAM and Code for Sustainable Home CfSH energy credits.

We are also well equipped to advise design teams on acceptable technology to achieve Local Authority targets for renewable energy.


Using EDSL Tas a fully accredited (CIBSE AM11) software we can provide assessments of summertime overheating risks for BREEAM credits.

We also produce BB101 reports for schools and CIBSE TM52 Adaptive Overheating Reports. Thermal Models can be generated to deliver building peak heating and cooling loads which engineers can use as part of the design process.
