Measurement and simulation of energy use in a school building

Abstract

This paper presents the development of a wireless temperature monitoring system and the application of measurement data for computer model validation, and its application to the simulation of energy use in a school building in Cacak, Serbia. The system for temperature monitoring was realized with a GPS/GPRS (Global Positioning System/General Packet Radio Service) system for low power data acquisition, using an MSP430 Texas Instruments microcontroller. With respect to heat loss analysis, the continual measurement of ambient and inside temperatures with a sampling time of one hour has been performed. For the simulation, DesignBuilder software is used. The simulation model, which reproduces the temperature measurement of school buildings, was developed and tested for energy analysis. Results are used to develop generalized guidelines for the determination of the efficiency of energy saving measures and the evaluation of low-energy buildings.
