This document discusses barriers to using dynamic simulation techniques for building retrofits. It proposes a simplified energy modelling technique and evolutionary algorithms to provide optimal retrofit solutions. This new solution aims to remove barriers like the steep learning curve, time consumption, and high costs of current simulation software by offering online and licenced versions at competitive pricing. It expects to become commercially viable within 3 years through online sales and expanding to other countries.
