Among world's effort to take action to the effect of climate change, a district in Korea with a progressive mind took its first step in realizing a net-zero energy ecological center. The concept of net-zero energy building design can only be stated as a fact if the simulated energy demand and the actual monitored usage can be reflected upon its variances. Hence, in this research, the quantitative data sets of simulated and monitored usages were analyzed by comparison and to determine its specific occurrence of variances. From the simulation report, energy demand and the consumption were compared and analyzed based on the data collected from March 2012 to February 2013, through the monitoring system in the subject building. The comparison between the demand and consumption was made in following categories: heating and cooling energy consumption and the energy production from geo-thermal heat pump, lighting energy demand and electricity consumption for lighting, and hot water demand and the energy gained by solar heating. The original programming had changed during actual residence and increased the energy demand, which became the source of error between the simulated data and the monitored consumption. Since this research is based on monitoring of the project building per annum, there could be error occurring form the profile change, weather patterns, or the energy usage patterns by the occupants. Therefore, the further research must be followed with the accumulated data in long-run. |
