Performance modelling & analysis

Performance modelling and analysis involves developing a model that usefully represents a complex system.

We use these models to predict, assess and analyse the dynamic and complex interactions that influence environmental performance. This informs policy-makers and supports the decision-making process for building design and operation.

We have led and contributed to the development of a number of built environment performance modelling and analysis tools. These tools encompass a diverse range of environmental parameters, such as:

  • thermal comfort;
  • overheating;
  • pollution;
  • thermal bridging;
  • indoor air quality;
  • energy demand; and
  • hygrothermal patterns.

Our modelling portfolio includes the following tools:

Belgrade Domestic Energy Model (BEDEM)

A city scale semi-empirical building stock model.

DOMEUS-Energy

A housing stock energy-use model that uses localised urban temperature data from the LUCID project to assess the impact of the London heat island on variations in domestic heat demand.

EPG2

A bespoke batch EnergyPlus file generator for building stock models.

ETI CRaB Model

A systematic modelling framework based around a multi-zonal physics-based simulation model. It allows ‘what if?’ questions around the interaction of people, buildings and heating systems to be explored in single case study buildings.

ETI-Thermal Efficiency Model

A bespoke stock-level model based around the BREDEM methodology for the analysis of mass retrofit options for the UK existing housing stock.

HIDEEM

A model to monetise the health impact associated with energy efficiency changes in dwellings in the UK.

PolyPol

An in-house post-processing tool for EnergyPlus that models contaminant transport, accounting for multiple pollutants and the influence of indoor environmental conditions on pollutant decay.

UCL-HAMT

The Combined Heat and Moisture Transfer model simulates the movement and storage of heat and moisture in surfaces simultaneously from and to both the internal and external environments.

The HAMT model is incorporated into the EnergyPlus.
