Dynamic Simulation Modelling (DSM) sometimes also referred to as Thermal modelling is a more powerful tool than SBEM for the calculation of building energy assessments.
What is DSM?
DSM is an integrated process that performs a dynamic whole building analysis and hence assesses the thermal performance of a building. There are various software tools that provide DSM capability and at AYNAM Energy we use the Virtual Environment software provided by IES Ltd.
The building design and specification is translated into a 3-dimensional thermal model. The thermal model is a representation of the actual building within a virtual built environment with specific location and orientation. The thermal model can be used for multiple purposes, essentially to influence the design of the proposed building or to carry out an assessment of an existing building. The different analyses carried out using DSM software can be categorised as follows.
- Energy Compliance Calculations (Section 6/Part L2)
- EPCs for England, Wales, Scotland and Northern Ireland (Level 3 to 5)
- Thermal Comfort assessment for buildings (CIBSE TM52 or TM59)
- Thermal modelling assessment for naturally ventilated buildings (CIBSE Guide A and AM10)
- Passive Design and Building optimisation analysis
- BREEAM assessment with regards to energy, health and wellbeing, daylighting and renewable energy credits
- Building integrated LZC technologies assessment
There are many benefits with utilising DSM within a project – early in the design process and examples are:
- Assessment of building materials and fabric specification in relation to energy efficiency for the proposed building
- Predict the likelihood of overheating for the intended building design
- Present technical evidence in relation to energy requirements for sustainability or planning statements
- Present a predicted CO2 rating for the proposed design and investigate the impact of alternative measures upon this CO2 rating
- Daylight calculations can help designers investigate the impact of natural light and allow for maximum exposure
- Solar shading calculations can be used to assess cooling loads and also to investigate summer shading devices
At AYNAM Energy we have a highly skilled team of Thermal modellers that can help in meeting your project needs.
