This study aims to present the energy efficiency of Zero Energy Building with PV, solar heat energy system by using RETScreen. The results are as follows; First, Zero Energy Building is consist of four factors. Passive factor(insulations, lighting facilities), Efficiency factor(high efficiency appliances), Eco factor(green technologies like rainwater reuse), Active factor(utilization of renewable energy). Senond, case study shows that an advanced countries like America, Germany have introduced the Zero Energy Building in variety of structures. On the other side, it is shown that the Zero Energy Building is not common in countries of Asia. Third, the analysis results of the Zero Energy Building technical factors in Korea and foreign country are as follows; we analyzed foreign and domestic technical factor and found that foreign cases applied large portion of active factor and small portion of eco factor. On the contrary to this case, domestic cases mainly applied passive factor and treated the introduction of the active factor as a trial factor. Fourth, energy efficiency evaluation results show that energy efficiency of 8.7% with PV, 6% with solar heat energy was deduced. And if value of variables are changed, the energy efficiency seems be more higher. Finally, Zero Energy Building is uncommon in Korea, it will be an ideal concept with goverment's investments on green building and development of renewable energy. |
