This study aims to analyze community support methods and specific attainments of UR rental housing complex S in Japan and examine the present state of community formation.. UR rental housing S is part of the community revitalization support project launched by UR Urban Agency for creating exchanges among residents in the rental housing complex and in this study, the community support project from February to November 2013 was considered. As community revitalization support tasks, five types of events and exchange meetings were held. While the events and exchange meetings continued, even the residents who did not join the residents' association began to make an exchange with each other and their identity as residents enhanced, which means there was a change in the sense of community. Moreover, it is thought that a good solution to maintaining the chance for the events and exchange meetings after the support project is that residents of the younger generation actively cooperate in management as the residents' association members. 5 years after the support project, the present condition of activities of complex residents was examined, but the Residents' Association was disbanded due to the aging of residents, a growth in residents and low participation rates of the younger generation. Besides, there is a complete absence of community activities in the complex now.

This study intends to investigate the characteristics of the foul smell of sewer pipes near large apartment complexes as complaints about offensive odors have drastically increased in urban residential areas. Targeting apartments where people actually complained about foul orders, the study result revealed that components in the smell of the water-purifier tank of the target apartment were very similar to those of sewage treatment plants and night soil treatment plants. Measuring components of odors inside the management layer of tank showed that the concentration of hydrogen sulfide was 10ppm, which is approximately 160 times the safety standard of 0.06ppm; the concentration of mercaptan was 0.9ppm, which is about 220 times the safety standard of 0.004ppm. The source materials of foul odors were discharged outside through ducts, and those households living near outlets producing bad smell complain that it gets worse depending on the air pressure or wind direction and strength, and they could not even open windows. As well, these source materials were transferred by discharge pumps to public sewer pipes outside the apartment complex. While discharge pumps starts operating, they remain on the sewer pipe and then begin to spread over to roads through small openings of manholes on the road. Then, the smell offends passers-by and residents near the road, leading to a lot of complaints. The study results suggest that, among the sources of foul odors in sewer pipes of residential areas, especially those from the water-purifier tank of large apartments, hydrogen sulfide should be the main target for follow-up treatment.

A model of apartment heating load in a district heating system could be useful in the management and utilization of energy resources, since it could predict energy usage and so could assist in the efficient use of energy resources. The heating load in a district heating system varies in a highly nonlinear manner and is subject to many different factors, such as heating area, number of people living in that complex, and ambient temperature. Thus there are few published papers with accurate models of heating load, especially in domestic literature. This work is concerned with the modeling of apartment heating load in a district heating system in winter, using the reduced least square support vector machine (LS-SVM), and with the purpose of using the model to predict heating energy usage in domestic city area. We collected 23,856 pieces of data on heating energy usage over a 12-week period in winter, from 12 heat exchangers in five apartments. Half of the collected data were used to construct the heating load model, and the other half were used to test the model's accuracy. The model was able to predict the heating energy usage pattern rather accurately. It could also estimate the usage of heating energy within of mean absolute percentage error. This implies that the model prediction accuracy needs to be improved further, but it still could be considered as an acceptable model if we consider the nonlinearity and uncertainty of apartment heating energy usage in a district heating system.

PM10, NOx, and $O_3$ were measured at six locations, of which each three is horizontally and vertically distributed respectively, in an apartment complex around the heavily traffic road. Those were measured seven times a day with two hours interval starting from 8 o'clock in the morning for 15 days during May 2005 $\sim$ September 2005. PM10 and NOx showed high concentrations in rush hours while low concentrations in midday due to the direct emissions from automobiles in operation. Temporal variations of 01 showed very much similar trend appeared in normal urban atmospheres. The spatial distributions of PM10, NOx and $O_3$ showed that almost all of concentrations were higher in a row of Roadside > Surface at 130 m apart from the road > Surface at 230 m apart from the road > 3rd floor of apartment building > 15th floor of apartment building > 27th floor of apartment building. Model equations, which can project spatial concentration distributions, were constructed by combining the horizontal and the vertical linear regression equations derived from six mean values corresponding to six measuring locations. According to inter-comparison of PM10, NOx, and $O_3$ with the constructed model equations, concentration gradients were higher in a row of Vertical direction of NOx > Vertical direction of PM10 > Horizontal direction of NOx > Horizontal direction of PMIO > Vertical direction of $O_3$ > Horizontal direction of $O_3$. Why concentration gradient of particulate PM10 is lower than that of gaseous NOx is in question, and should be studied.

최근 몇 년 사이 공동주택 리모델링을 둘러싼 여건의 변화는 리모델링의 활성화라는 입장에서 볼 때 매우 고무적이라 할 수 있다. 리모델링의 추진에 대한 단지 내 다른 주민들의 반발을 어떻게 조정할 것인가가 주요한 과제로 대두되었고, 리모델링을 위한 재원 조달과 리모델링 이후의 자산가치 변화가 핵심적인 쟁점으로 부각되었다. 특히 많은 언론의 보도에도 불구하고 리모델링에 의한 자산가치 즉 부동산 가격의 상승효과가 뚜렷하게 입증되지 못하고 있으며, 금융기관 역시 리모델링 이후의 자산가치 상승에 대해 상당히 보수적인 평가를 하고 있기 때문에, 입주자들은 리모델링을 위한 재원의 조달에 상당한 어려움을 겪고 있을 뿐만 아니라 리모델링 사업의 성공여부도 확신하지 못하고 있다. 제도개선은 동 단위 리모델링을 보다 효율적이면서도 도시와 단지 전체의 관리 방향과 조화되는 방향으로 추진되어야 하며, 또한 공공지출을 최소화하면서도 리모델링을 실질적으로 지원할 수 있는 제도적 방안이 강구되어야 한다.

During the initial design stage of apartment complex, the photovoltaic(PV) system has been considered as an alternative of renewable energy system and planned to install at the rooftop floor level in general. The electric power generation characteristics can be influenced by the block layout, building orientation and roof top structure because of azimuth angle, tilt angle, and partial shading. This study aims to investigate power generation characteristics of photovoltaic system in apartment buildings by considering the partial shading conditions due to the block layout, building orientation and roof-top structures. For the photovoltaic module arrangement planning in rooftop floor level, shading areas were firstly analyzed due to the adjacent building structure. And the annual and seasonal power generation of PV system were analyzed through the PVsyst simulation results. The results show that shading period at the roof top surface can be increased due to the parapet and water tank. Initial design power capacity can be decreased by considering the daily insolation period and distance between PV modules through the shading simulation. As the number of PV modules decreases, the annual power generation can be decreased. However annual power generation per unit area of PV modules can be increased and performance ratio can be increased above 80%. Also the power generation of PV system can be critically affected by building orientation and the performance ratio can be drastically decreased in east-oriented buildings due to the shading problems caused by adjacent structures at roof top level such as parapet and water tank.
