CLIENT QUOTES
How well do we work within a design team? “Ed (Rimmel of Turner and Townsend) and Steve (Saxton) were a pleasure to work with and they worked well with Craig Pugh of MMS... I will gladly work with T&T and JPA again, and want to thank everyone involved for putting it all together.”

Thermal Modelling

Our in-house specialists can carry out detailed dynamic predictive modelling of a proposed scheme to ‘test-drive’ the design before detailed design commences. These tools are useful in demonstrating:

  • The appropriateness of the natural ventilation strategy
  • The true benefit of passive design measures
  • Services requirements for Mechanical Engineering Design
  • How to improve the energy efficiency of the building
  • The impact of the proposed development on existing buildings
  • Materials selection
  • Carbon emissions of the building
  • Potential for renewable energy

We use Thermal Modelling techniques that enable us to determine the thermal performance of a building at the design stage.

The internal conditions of a building are a result of the thermal response of the building to external weather conditions; therefore the design of heating and cooling systems for the building are critical. Using thermal modelling software enables the simulation of realistic conditions to determine the thermal performance of a building and enables us to design the systems accordingly.

Our IES Virtual Environment software uses calculations that are based on dynamic conditions rather than steady state calculations and takes into account many different factors such as the form, fabric, orientation, services and use of the building. This leads to a much more realistic and accurate prediction of performance.

Filled Velocity

Thermal Modelling can encompass:

  • Daylighting Assessments*; in order to optimise the amount of natural daylight in the building design.
  • Lifecycle Analysis; simulation software predicts the annual energy consumption of the building; therefore the running costs of the building can be calculated.
  • Part L compliance; The modelling software can also provide Part L compliance calculations and certification for submission to Building Control.
  • Energy Performance Certificates; JPA can now offer an EPC Assessment Service; the asset ratings of buildings are calculated using IES VE software, which is also used for assessing compliance with Part L of the Building Regulations.
