Carpenter Davies Partnership have the necessary experience and knowledge, particularly with respect to building services elements and BREEAM certification, to carry out full dynamic thermal simulations. We use CIBSE AM11 approved software and can therefore meet the required BREEAM criteria.

Dynamic Thermal Simulation takes a holistic view of the building and simulates how it reacts dynamically with the external conditions. Using detailed real climatic data for the building’s location, this detailed analysis allows calculation not only of what the peak loads on the building may be, but also at what time of the day they will occur.

This provides design teams with the information required to assess the performance of natural ventilation and other passive design techniques, make glazing/fabric/solar shading decisions, prove compliance with Building Regulations and size and select HVAC systems correctly.

Details of the energy and environmental performance of the building such as annual energy consumption and running costs, heating/cooling loads, thermal comfort of occupants and carbon emissions can be reviewed and the design can then be modified in order to optimise the energy and environmental performance of the building. The simulation results can also be used to fine-tune the heating and cooling systems and avoid any over-design of plant.

Dynamic Thermal Simulation can determine which mode of ventilation is best suited to your building in terms of design, location and end-use; be it natural, mixed-mode or mechanical ventilation. The simulation takes full account of building height and location, fenestration openings, stack effect and wind forces.
Dynamic Thermal Simulation can test ventilation strategies such as natural ventilation, the use of atria, sizing of vents/openings, night-time cooling and automatically opening vents.

Dynamic Thermal Simulation also provides design teams with the information required to size and select HVAC systems correctly. Dynamic Building Simulation takes into account the effect of any other aspects of the design included to control internal temperature such as the use of thermal mass and solar shading.

One of the key design challenges with natural ventilation strategies is predicting internal summertime temperatures. Dynamic Thermal Simulation can address this issue by calculating air flows and internal summertime temperatures.
