DSM - Commercial Buildings Energy Assessment

DSM - Dynamic Simulation Model is an energy assessment method which has been developed to calculate energy ratings for complex commercial buildings. Typically DSM consultants would be contracted to calculate energy ratings for new and existing buildings using specialised DSM software. The software has been approved for use by CLG (Communities and Local Government).

DSM Ratings can be calculated usually by submitting the relevant information to the assessor, by submitting drawing plans, and the materials used in the construction of the building for new units. Energy efficiency calculations are made by using 3D modelling software for complex buildings. Some buildings will require the use of SBEM

Buildings in the Commercial Sector

Buy-to-let private investor properties will mostly be covered by EPC's issued by Domestic Energy Assessors. for further information please see Rented Property EPC & Social Housing EPC.
Commercial Buildings will be assessed using SBEM energy assessment methods. New Houses can be assessed using Standard Assessment Procedure (SAP) by inspection of building plans and the materials used in the construction prior to being built. Property Developers can provide this information to a SAP Assessor.
