Permanent address of the item is
Study of energy efficiency has been very hot research topic in these days. Benefits from highly efficiency system are obvious. Greenhouse effect can be diminished, resources are protected and society development becomes sustainable. Development of information technology provides new solution to exiting problem from different fields. One of the application areas of information technology can be focused on monitoring energy performance of commercial building, which traditionally has been believed that this is one of main energy consumption sources. Main object of this thesis work is to design a web application that is used to monitor energy usage of commercial building and provides reference standard on that particular room. The recommend energy usage is computed from standard EN-15193, which is drafted by EU and targeted to reduce unnecessary energy waste. Wireless sensor work has been utilized in this work for collecting environment data from field devices deployed across Tampere University of Technology. Adapter collects data from various different sources and forward to database located in company through Ethernet. Transmission control protocol/internet protocol connection is built up between host computer and company database. Raw data pass through filter energy predefined by user. Unrelated data is filtered out and relevant data are grouped and trigger action as long as data has satisfied specific conditions. At the same time, qualified data are stored within database which is managed by Hibernate framework. The Web application is developed from Spring MVC framework and is responsible for interaction between database and user interface. It also provides user interface to enter value of required parameters and displays final result. In this case, users do not need to install client application on their own computer, rather they can access to whole application by using web browser. Interaction between user and application is communicated through internet. Moreover, upgrade application process can be avoided on user side. As long as application upgrade is performed on server side, all client terminals are synchronized all together. The result mainly shows functional web application from which information change between client and server is implemented. Energy usages from different control schemas are displayed on the Google chart. The energy analysis can be evaluated on hourly basis and daily basis. Finally, the optimal solution to particular room is derived from comparison.
