Building energy efficiency and life cycle cost is important considerations when designing a building. The early design phase provides more opportunities and flexibility as there are fewer constraints. In typical practice, design teams use energy simulation tools to estimate energy consumption/cost using consider several parameters and their combinations. Many tools consider only a small set of combinations of parameters for energy efficiency/life cycle cost. Furthermore, building professionals lack an easy-to-use tool that is available to all related professions and facilitates the discussion between architects and engineers. To fill this gap, a tool called early Design Optimization Tool (eDOT) has been developed to help the design team visualize the spectrum of building design solutions for energy efficiency. eDOT performs annual energy simulation of a five zones simplified model using EnergyPlus. eDOT performs a sensitivity analysis that helps a designer understand the impact of key parameters on energy performance.Parameters such as Azimuth, Aspect Ratio, Overhang, Window to Wall Ratio (WWR), Roof Insulation thickness, Wall Insulation thickness and Glass Type are considered in the tool. The tool uses cloud computing and machine learning algorithms to speedup the simulation process.
