Decreasing actual greenhouse gas will be difficult if it is not solved addressed in architectural fields. Zero emission building or zero energy building, maximize the efficiency of energy, which means the building can operate by their own renewable energy facility without any other supplying. To be a zero emission building, a building needs realization of high efficiency low energy consumption, construction of building its own energy production facilities and lastly a power grid connection. According to increasing of DC load about TV, LED lighting, computer, IT in building for living and business, it is expected the save of energy when the system of AC power distribution change into the system of DC power distribution. Renewable energy exists a big different rate produced by outside environment. When electrical power overproduce, it can supply for system. Otherwise, if electrical power produce less, it can receive supply from system. Send and receive power can lead to zero to annual standard. This paper shows the simulation about efficient control of power conversion which is related to DC power distribution of architecture and DC output of renewable energy by using L-type converter.

With the change in Earth's ecosystems due to climate change, a number of studies on zero energy buildings have been conducted globally, due to the depletion of energy and resources. However, most studies have concentrated on residential and office buildings and the performance predictions were made only in the design phase. This study verifies the zero-energy performance in the operational phase by acquiring and analyzing data after the completion of an exhibition building. This building was a retention building, in which a renewable energy system using a passive house building envelope, solar photovoltaic power generation panels, as well as fuel cells were adopted to minimize the maintenance cost for future energy-zero operations. In addition, the energy performance of the building was predicted through prior simulations, and this was compared with actual measured values to evaluate the energy performance of the actual operational records quantitatively. The energy independence rate during the measurement period of the target building was 123% and the carbon reduction due to the energy production on the site was 408.07 tons. The carbon reduction exceeded the carbon emission (331.5 tons), which verified the carbon zero and zero-energy performances.

Architectural market in the world is trying to develop Zero Carbon Buildng that doesn"t use fossil fuel. Residential building that thermal load such as heating and domestic hot water is over 70% in energy consumption is easy to make Zero Carbon Building compared with office building that is mainly electric load. So, As a preliminary for analyzing the effect of Solar thermal system in the building, an annual energy consumption of residential building and total heat loads are calculated. Based on this result, three alternatives of solar thermal system for hot water and heating are applied in the building while installation area is increasing. Solar thermal system is applied on balcony and roof of apartment building as the way to reduce thermal load. In the first case that solar thermal system for hot water is applied on the balcony, optimum installation area is $56m^2$. And you could install $40m^2$ of this system in the roof that angle is $30^{\circ}$. In the second case of solar thermal system for heating and hot water, you can install $40m^2$ on the roof. As a result of economic evaluation, the most economical application method is to install $40m^2$ of solar thermal system for only hot water on the roof of the building. At that time, you can payback the initial investing cost within 10 years. And carbon emission of this method can be reduced until about 4 ton per year.

The continuous development of science and technology since the Industrial Revolution and the development of human civilization are based on the use of fossil fuels. However, the use of fossil fuels is increasing the greenhouse gas, the main cause of global warming, and global warming is an extreme climate anomaly that is rapidly increasing human and material damage. Therefore, efforts are being made worldwide to return greenhouse gases to pre-industrial levels. In Korea, 2050 carbon neutrality has been set as a major policy and efforts are being made to curb carbon emissions in the overall industry. Carbon emission suppression is based on the minimization of fossil fuel use, and research and development are underway on building a zero-emission house that minimizes the energy used in buildings in the construction field. Therefore, in this study, as part of the zero-emissions water system construction, waste resources generated at industrial sites were utilized and an integrated lightweight concrete solar panel grafted with a concrete lightweight panel and solar panel was manufactured and the possibility of its use was evaluated.

국토교통부는 녹색건축물 조성을 촉진하기 위해 '17년 공동주택은 냉,난방 에너지 90%('90년 대비) 절감 목표를 수립하였으며, 2015년 UN 기후변화회의(2015 United Nations Climate Change Conference)에서 당국은 2030년 배출전망 (BAU)인 8억 5060만 ton $CO^2$ 대비 37%를 감축하겠다고 발표하였다. 이를 만족하기 위해서는 가장 많은 탄소 발생을 야기하는 건축물에서 탄소배출 최소화를 위한 조치가 시급하며, 이에 건물 사용 시 발생하는 탄소배출 감축을 위해 필요한 건물 성능 강화를 유도하는 커미셔닝에 대한 관심이 높아지고 있다. 그러나 현재 건설업계에서 커미셔닝은 법제화되어 있지 않고 건설 참여자의 수행의지 및 효과 홍보 부족으로 인해 활성화 되어있지 않다. 또한, 녹색건축으로의 인증을 획득하는 과정에서 조차 커미셔닝은 필수 수행 항목으로 지정되어 있지 않아 국내 커미셔닝은 그 효과 대비 저평가 받고 있는 실정이다. 이에, 본 연구에서는 커미셔닝의 효과에 대해 기술하고, 해외 녹색건축인증 LEED, BREEAM을 기준으로 커미셔닝이 녹색건축에 있어서 어떻게 평가받고 있는지 국내 G-SEED와 비교, 분석하여 국내 녹색건축인증에서의 커미셔닝 필수화를 제안하고 나아가 커미셔닝이 국내에서 활성화 될 수 있도록 건설 주체자의 인식 변화를 유도하고자 한다.
