| Abstract |
HVAC&R(Heating, Ventilation, Air Conditioning & Refrigeration) system consists of components and equipment arranged in sequential order to condition the air, to transport it to the conditioned space, and to control the indoor environmental parameters of a specified within required limits. It is the most energy consuming building services representing approximately 50% of the final energy use in the building sector. The purpose of this study is to provide the energy saving strategies and it is a main target in the development of HVAC&R system design guideline. Although there is a large number of building simulation tools available, these tools are mainly used for thermal load calculations in view of sizing of HVAC&R systems. This work is to research and enable useful applications of HVAC&R energy analysis tool for the integrated low-energy building design support. This paper discusses the results of system impact assessment for energy consumption characteristic of office buildings. A prototype commercial building, a 37,000㎡ office building, was selected for the energy simulation and for each HVAC&R set, total 960 variables could be identified. The results of the analysis are presented as percent changes in total cooling and heating energy consumption from an established baseline. |
