Alternative Design Exploration using K - Nearest Neighbor Technique and Semantic Web Technology in an Energy Simulation Tool

An energy simulation tool is a tool that is used to calculate energy demand of a building. The existing energy simulation tools carry out alternative design exploration using optimization method. This method works by varying its parameters to obtain better energy performance. The method needs to calculate energy performance every time each parameter is changed. This practice causes the method is slow. Therefore, new techniques to carry out alternative design exploration are used, they are: K-Nearest Neighbor Technique and Semantic Web Technology. The advantage of the above techniques is that they do not need to calculate energy performance for any parameter combination. Instead they will select parameter combinations that will give better design. Experiment shows that, in an alternative design exploration, Semantic Web performs better than KNN in terms of speed. Another advantage of Semantic Web is that there is no need to preprocess data.
