Using energy modelling for calculations of energy savings, payback and return on investment for a typical commercial office building with IBT systems

This paper describes and focuses on the applications of a new range of smart building products, particularly Integrated Building Technology (IBT) systems, with the aim to demonstrate savings for improving energy efficiency and indoor environments in buildings. A typical commercial office space has been modelled via dynamic computer simulation software, considering scenarios of before and after the installation of IBT systems. This has then been compared against different building regulations and standards e.g. UK Building Regulation 2006 and ASHRAE 90.1. The study revealed 35% of energy savings per year, a payback period of nearly 1 year, and the return on investment (ROI) of approximately 65% using the IBT systems.
