최근에는 '빈집 및 소규모 주택정비에 관한 특례법'을 제정하여 정부정책사업으로 가로주택정비사업을 활성화하기 위해 노력하고 있다. 그라나 이 정책은 원도심의 노후 불량 건축물이 밀집한 가로구역에서 소규모 정비사업보다 대규모정비사업 이 더 적용돼서 실적이 매우 미흡하고 제도개선이 필요한 실정이다. 그래서 본 연구에서는 전문가 간담회와 설문조사를 통해 대규모 정비사업과 차별화된 법적인 공공지원 방안을 도출한다. 연구결과는 '층 면적 비율'과 '건축물의 높이제한 기준 완화'가 가장 효과적인 반면 '지자체에서 주민공동시설 유상매입 후 운영'은 미미한 것으로 나타났다. 이러한 결과는 그 지역의 사회환경을 파괴하지 않고 노후한 주택 지역을 정비사업을 하는 동시에 취약계층에 임대 주택을 제공함으로 공공기관에 큰 이익이 될 수 있다는 전망이다. 그리고 소규모 정비사업인 가로주택사업을 활성화하기 위해 효과적으로 도입하여 적용 가능한 특례항목을 제시함으로서, 도심지내 임대주택건설을 유도하고 세입자 우선공급을 통한 둥지내몰림 현상을 방지하며 신혼부부나 청년 등의 젊은 층 입주를 통해 노후주거지에 새로운 활력을 도모하는데 도움이 될 것으로 기대한다.

This study was to assess the lifetime cancer and non-cancer risk of exposure of worker and user at public facilities in Korea to volatile organic compounds (VOCs). We measured the concentrations of two aldehydes and five VOCs in indoor air at 424 public buildings that 8 kinds of public facilities (70 movie theaters, 86 offices, 86 restaurants, 70 academies, 22 auditoriums, 30 PC-rooms, 30 singing-rooms and 30 bars) all over the country. There were estimated the human exposure dose and risks with averages of the using-time and frequency for facility users and office workers, respectively. Carcinogens (formaldehyde, acetaldehyde, and benzene) were estimated the lifetime excess cancer risks (ECRs). non-carcinogens (toluene, ethylbenzene, xylene, and styrene) were estimated the hazard quotients (HQs). The average ECRs of formaldehyde and benzene for facility worker and user were $1{\times}10^{-3}{\sim}1{\times}10^{-4}\;and\;1{\times}10^{-4}{\sim}1{\times}10^{-5}$ level, respectively, in all facilities. HQs of four non-carcinogens did not exceed 1.0 for all subjects in all facilities. The estimated ECRs for restaurant and auditorium were the highest, and the PC-room and bar were the next higher facilities. Furthermore, people in a smoking facility had the highest cancer risk. Higher ECRs of formaldehyde and benzene were observed in indoor smoking facilities such as restaurant and auditorium. Higher HQs of toluene and xylene were observed at the restaurant and office building.

Due to reinforcement of international environment regulation and high oil prices, interest in renewable energy is growing. Countries participating in UNFCCC are continuously putting efforts in reducing greenhouse gas after enforcing Kyoto Protocol into effect on Feb, 2005. Energy used in buildings, which relies heavily on fossil fuel accounts for about 24% of total energy consumption. In this study, air, geothermal and water source heat pump systems for an 322 $m^2$ auditorium in an office building is simulated using TRNSYS version 17 for comparing energy consumptions. The results show that energy consumptions of air, geothermal and water source heat pumps are 14,485, 10,249, and 10,405 kWh, respectively. Annual equal payments which consider both initial and running costs become 5,734,521, 6,403,257 and 5,596,058 Won. Thus, water source heat pump is the best economical choice.
