Energy modelling of houses and other buildings helps the designers to determine the energy performance of the building at an early stage. It furthermore gives the advantage of altering the building's design early in the planning phase to ensure that it fulfils requirements of increasing energy demands. Energy models also serve as a tool to predict the energy consumption and thereby energy cost of running the building. Energy modelling is becoming widely used but there are many uncertain
parameters associated with any energy model that should be validated for accuracy.
In this study a house was equipped with measuring equipment to verify the results from two different energy models, an excel model developed by Iceland Innovation Center and a 3D-model from Autodesk Revit using Autodesk Green Building Studio for Revit. It furthermore serves the purpose of testing the quality and usability of the measuring equipment used.
The report is conducted with a non-engineering approach which serves the purpose of considering the energy models and their complexity from a non-engineering angle.
This is important, with lawmakers dictating the use of energy calculations and simulation to some extent within the architecture profession.
