• Dynamic Simulation Modelling

    Whole building energy performance simulation

What is Dynamic Simulation Modelling (DSM)?

DSM is accurate whole building performance simulation. DSM is commonly known as a Thermal Model which can be used to carry out building compliance assessments under the SBEM (Simplified Building Energy Model) approach to satisfy UK/ROI Regulations Part L and NI Part F. The advantage of progressing your SBEM into a Thermal Model / DSM is down to the increased accuracy achieved from 3D modelling a building.

DSM models are used by sustainable design experts around the globe to produce an accurate, sub-hourly, thermal simulation of new and existing buildings of any size and complexity. This model incorporates air flow from ventilation and openings to reflect the impact it has throughout the building. The model uses actual weather / solar data specific to site location.

Dynamic Simulation Modelling Thermal Model DSM

What is DSM Model used for?

  • Design / As Built SBEM – Part L and Part F compliance

  • EPCs

  • Plant Sizing – working alongside M + E contractors to size building HVAC

  • Daylighting Analysis

  • Thermal Comfort Analysis

  • Overheating Issues

  • BREEAM reports – We offer a range of DSM reports

Dynamic Simulation Modelling

Software

At 360 Energy we carry out dynamic simulation models using IES VE software, this world leading software is the software of choice from many multi-national companies when designing new buildings. 360 Energy are fully trained in IES software and with over 12 years’ experience in the field.

  • TM52 – The Limits of Thermal Comfort: Avoiding Overheating in European Buildings

    Overheating has become a key problem for building design. The need to reduce energy consumption whilst dealing with global climate change has reduced the options available for building comfortable, low-energy buildings. Research has been directed towards methods for increasing indoor winter temperatures but this can lead to lightweight, highly insulated buildings that respond poorly in the summer. (Source: CIBSE) CIBSE has responded by forming the CIBSE Overheating Task Force. DSM is used to model buildings against CIBSE TM52 targets, mechanical and natural ventilation strategies can be modelled to achieve compliance.

  • TM59 - Design methodology for the assessment of overheating risk in homes

    Generally SAP (Standard Assessment Procedure) is used to calculate the energy demand in homes, however due to building regulations having no requirement to calculate overheating in homes it has become a complex issue in new houses due to modern design. TM59 is an adaptation of TM52 for homes. DSM can also be used to model domestic properties to assess against overheating and thermal comfort.

  • HEA 04 - Thermal comfort

    BREEAM projects have 3 available credits to show compliance with HEA 04, this credit is achieved through DSM of the proposed building against the end users thermal comfort. Thermal comfort is assessed against CIBSE TM52 standards. The building is assessed against its capabilities of providing a comfortable environment in each zone through building HVAC / Natural ventilation strategies. The building is also assessed against climate change, IES VE ability to incorporate predicted weather files provide the design team the ability to future proof the building in relation to human comfort.

  • HEA 01 – Visual Comfort

    BREEAM project are assessed against HEA 01 to ensure daylighting, artificial lighting and occupant controls are considered at the design stage to ensure best practice in visual performance and comfort for building occupants. DSM models the proposed building with surrounding buildings to give a true reflection of zone lighting.

  • ENE 01 - Reduction of emissions

    BREEAM assess buildings against their reduction in c02 emissions against the target emissions outlined to achieve building control compliance. As DSM models buildings more accurately, this provides the best case scenario to achieve up to 5 credits.

  • BB101 - Ventilation, thermal comfort, and indoor air quality in schools

    All UK schools are assessed against BB101 standards, these standards run along the CIBSE standards as outlined above. DSM is required to produce compliance reports.
