Introduction

This guide provides instructions on how to model windows using HOT2000 Version 15 for an energy simulation and what to expect in terms of the calculated thermal performance specifications.

The intention of this guide is not to replace existing NRCan publications but rather to outline key aspects related to the modeling of windows under the EnerGuide Rating System. Modelers who are looking for a more accurate representation of window performance in their simulations, for example, in work being done for building code compliance will find this technical content of interest.
