도시에서의 에너지는 주로 인력에 의해 관리되고 소비된다. 전력이나 물, 가스 등 살아가는데 필요한 에너지는 화석연료로 생산되거나 만들어진다. 따라서 전력 등과 같은 에너지의 소비가 많을수록 이산화탄소 배출이나 지구온난화가 심화된다. 도시의 건축물에 대한 에너지의 공급체계는 건축물과 별도로 구성되어 있어 통합적 관리를 통해 사용량을 최적화하여야 한다. 본 논문에서는 스마트그리드 스테이션을 기반으로 한 스마트그리드 시티를 구축하는 방안을 제시하고자 한다. 이를 통해 홈, 타운, 시티를 거쳐 최종적으로 스마트 에너지 국가를 완성하게 된다.

A smart window is a new building material that can realize energy savings in a building. Smart windows can freely adjust Visible Light Transmittance (VLT) and solar gain coefficient (g-value) according to the situation. Smart windows include such technologies as Electrochromic (EC), Suspended Particle Device (SPD), and Polymer Dispersed Liquid Crystal (PDLC). Recent research on building energy savings through the VLT and g-value control functions of smart windows is being actively conducted and meaningful results are being drawn. However, since most of the research is focused on energy savings, research on the indoor environment is somewhat lacking. A building is a space where people live and the comfort of life should be prioritized before energy savings. Therefore, in this study, analysis on the daylight performance of an office space was carried out. Through green building standards such as LEED, BREEAM, CASBEE, and G-SEED, the daylight performance was reviewed according to VLT value changes of the smart window. In addition, a study was conducted on the VLT range of the electrochromic façade that can maintain a comfortable indoor environment. The smart window used electrochromic control with a wide range of VLT. The study showed that the minimum VLT of a smart window that can satisfy G-SEED is 25% or more. In addition, it was found that the VLT change of the electrochromic smart window did not significantly affect the uniformity of the room. When the LEED standard was applied, the minimum VLT value of the electrochromic smart window that must be maintained according to each orientation of the building was derived.

This study used Bacillus licheniformis generating glycocalyx as a provective membrane to enhance the salt-damage resistance of cement mortars. The mortar specimens with Bacillus licheniformis exhibited a comparable compressive strength development and 1.1~1.3 times higher dynamic modulus of elasticity under 300 freezing and thawing cycyles when compared with the counterpart control mortar.

This study aims to build VR using BIM at our actual site, simulate it in a realistic background, and simulate new safety-related technologies being developed by our company rather than safety education contents to review optimal use plans for each field type so that the new technology can be effectively applied in the field.
