Advanced Building Energy Data Visualization is a way to detect performance problems in commercial buildings. By placing sensors in a building that collects data from example, air temperature and electrical power, then makes it possible to calculate the data in Data Visualization software. This software generates visual diagrams so the building manager or building operator can see if for example the power consumption is to high. A first step (before sensors are installed in a building) to see how the energy consumption is in a building can be to use a Benchmarking Tool. There is a number of Benchmarking Tools that is available for free on the Internet. Each tool have a bit different approach, but they all show how much energy consumption there is in a building compared to other similar buildings. In this study a new web design for the benchmarking tool CalARCH has been developed. CalARCH is developed at the Berkeley Lab in Berkeley, California, USA. CalARCH uses data collected only from buildings in California, and is only for comparing buildings in California with other similar buildings in the state. Five different versions of the web site were made. Then a web survey was done to determine which version would be the best for CalARCH. The results showed that Version 5 and Version 3 was the best. Then a new version was made, based on these two versions. This study was made at the Lawrence Berkeley Laboratory.
