Dynamic Thermal Modelling of an Office BuildingExecutive Summary Virtual Environment (IES) was used to help improving the design of the building performance by developing several properties of different materials within the building. This report looked into changing materials of a certain building such as glazing area, construction data and infiltration in order to demonstrate the building peak heating and cooling loads. The model was built on the base case analysis and allocated to be in Heathrow, London. In addition, it is used as offices building. Numerous changes in the buildings properties materials were carried out in order to decrease the peak heating and cooling loads of this building. The changes were then taken into consideration in the overall design so that it can aid to achieve the buildings thermal performance.Table of Contents1. Introduction1.1. Aims and Objectives1.2.
