Researches and developments on BEMS, which are the cutting edge technology for energy saving in buildings, are performed world-widely through sustainable management in various conditions. However, there are many obstacles to adapt the system in existing buildings because it needs not only the extra administrator who manages the energy, but also needs highly expensive equipments, which are designed for newly built buildings, to install. Therefore, there are numerous limits exist when applying the BEMS in established buildings. The purpose of this study is to evaluate the possibility of energy saving according to user's participation through related case study and to propose PEMS(Portable Environment Monitoring System) that could overcome the weakness of previous system. In addition, this study will assess the optimization of WSN(Wireless Sensor Networks), which is the essential technology to develop PEMS. Lastly, this study has performed field measurements as well as basic tests to evaluate the adaptability of PEMS in buildings. The result of this study is as follows ; 1) Energy saving of 10~20% in buildings can be achieved through energy feedback. 2) As the RF output power decreases from 0dbm to -25dbm, maximum reception distance of sensor node was reduced as well. 3) Maximum reception distance can be different depending on the RF output power differences and different types of materials. 4) As RF output power increases, the number of relay node reduced, therefore, the WSN showed more stability.
