Energy Modelling

Building Energy Modelling

Building Energy Modelling (BEM) is the practice of creating digital representations of a building’s energy flows, based on the principles of building physics and thermodynamics. Through BEM, we characterise the energy needs of an existing or future building and predict its consumption patterns. We run software simulations on our custom-built parametric models to study the effects of design alternatives on engineering projects, for both renovation and new constructions. We also provide financial guidance to manage the related investment project.

Guiding Principles

Our environmentally-sensitive recommendations are backed by our broad research base and follow a few essential guiding principles:

  • Life Cycle Assessment (LCA)
  • ASHRAE comfort standards
  • Human health, well-being and salutogenesis
  • Passive and active measures
  • nearly-Zero Energy Building (nZEB)
  • Future climate
  • Occupancy schedules and human behaviour
  • Analytics
  • Vernacular knowledge

Methodology: 7-Axis Modelling

  • Our 7-Axis method provides a framework that streamlines the modelling process and makes sure all relevant parameters are accounted for.
  • We co-design with the project architects and engineers, jumping in during schematic design so decisions are taken with energy efficiency in mind, avoiding costly changes in the final stages.
  • Multi-objective optimisation allows us to recognise the complexity of construction decisions and balance the essential variables: environmental impact, human comfort, and monetary cost.
