Dynamic Simulation Modelling

At Mainer Associates we look to use the latest methods and technologies in order to ensure the most appropriate solutions are specified on all our projects. The use of Dynamic Simulation Modelling (DSM) has been a key tool for both new build and refurbishment projects.


As a level 5 accredited piece of software, TAS (DSM) allows us to dynamically model complex buildings where a simple SBEM would not suffice.

Typically we now use TAS even for simple buildings as it is more cost-effective for our clients given the flexibility of the software to generate a number of different outputs.

Outputs for new build developments:

  • Level 5 EPCs
  • Part L compliance documents
  • Thermal Comfort Studies
  • Renewable Technology Studies
  • Daylighting calculations
  • Various reports required for BREEAM


The TAS tool allows us to appraise a number of different solutions and quickly compare the benefits from both carbon reduction and economic perspectives for refurbishment projects. Using TAS we are able to model the current performance of our client’s buildings in order that we can recommend the most appropriate refurbishment or retrofit solutions to ensure the long-term sustainability of our clients’ stock.

Part L2 A & B

Part L2A is an Approved Document dealing with the Building Regulations for the conservation of fuel and power in new buildings (non-dwellings). The latest addition is 2013 with 2016 amendments.

Broadly the document covers the content of the Building Regulation in England for the energy performance requirements of new buildings. This includes fabric efficiency standards, U Value requirements, building services performance requirements and other performance and calculation standards that new buildings must adhere to.

Part L2B is another Approved Document dealing with the Building Regulations, as above, but in existing buildings.

The document deals with consequential improvements required when properties are refurbished or the thermal envelope of the building are amended significantly.
