Energy Modelling Basics
An introduction to the Focal Engineering Blog, and a “back to basics” reminder of what energy models are all about.
Complexity: Beginner
Introduction
When I first started working in this industry, the word “model” typically referred to a physical representation of a building built by the architects out of balsam and plastic that we would all “ooh” and “aah” over. These days, computer models are used to simulate lots of different aspects of the building. The energy model is used to evaluate the energy profile of a building, that is, how the building uses energy, how much it uses, when it is used, etc.
This article introduces the concept of the energy model and talks about the most common reasons why you might need one.
What’s the purpose of an energy model?
Energy models can be used for multiple purposes, which will have a big impact on its inputs, complexity and cost. Most often, models are requested for one of the following reasons:
Design Assistance,
Code Compliance,
Green Building Certification, or
Incentive Program.
(I know, I know, this is a super short list of energy modelling purposes- just think of it as the energy equivalent of a “top four-ty” chart!)
