This study aims to propose appropriate evaluating method of noise emission from water supply and drain installations in apartment bathroom. Because KS(Korean Standard) about water installations noise in apartment bathroom only are establishing the measurement procedure of it, Evaluation and rating procedure is necessary to improve the sound insulation performance of the apartment and to reduce the apartment dweller's unsatisfaction with the noise. Thus, this study reviewed the standards and evaluating methods about the water supply and drain installations noise of many other country. We measured the noise emission from the installations in many apartment bathroom, and then we calculated the noises to dB(A), N, NC evaluated numbers. We analyze the coefficient of the corelation among the evaluated numbers to induce the appropriate method. As a result, the dB(A) method is most easy to evaluateing and very high corelated wth N and N index, So the dB(A) method is suitable to be adopted KS evaluating procedure of noise emission from water installations in apartment bathroom.

The main sources of the new house syndrome(sometimes it called sick building syndrome) are a concentration of formaldehyde (HCHO) and a concentration of total volatile organic compounds(TVOC). I had field measurements of indoor air quality in the apartment unit at medium-size cities(Y city, C city). I measured indoor air temperature, HCHO concentration in 16 units, TVOC concentration in 6 units and air tightness in 7 units. And I measured outdoor air quality, HCHO concentration and TVOC concentration. Mean concentration of HCHO was $357{\mu}g/m^3$(2006 standard=$120{\mu}g/m^3$), mean concentration of TVOC was $3,092{\mu}g/m^3$ and mean effective air leakage area was 193 cm2. There was a close relation between the indoor air temperature and HCHO concentration, between the indoor air temperature and TVOC concentration. Air tightness also had relation.

This study is to investigate the possibility of a quantitative analysis on sunshine right in apartment houses with a new evaluation index of shading area ratio(SAR) which represents seasonal average value of shaded portion of a window during definite period. SAR values of each apartment houses in a prototype building was calculated depending on apartment building arrangement types and orientations. Since the new method proposed in this research is able to measure the sunshine possibility of the each house in detail, which is more precise and descriptive than the existing method of sunshine judgment standard based on the sunshine hours only at winter solstice, it can be appropriately utilized as a highly qualified sunshine right judgment measures in apartment buildings.

The aim of this study was to develop the details of cross-laminated timber (CLT) envelops for satisfying the design standard for energy saving (DSEA) and passive standard in South Korea. When the same thickness of 180 mm concrete or CLT was used and the same materials for other layers were used for the roof, wall, and interlayer floor, the required insulation thickness for the different building envelopes in central, southern, and Jeju island was evaluated. As a result, compared to the concrete envelop, about 43 mm of insulation thickness was reduced for wall and roof with the CLT envelope. When the CLT envelopes were modified to protect the CLT from moisture based on FPInnovations (2011), the insulation thickness was further reduced by 12 mm. When the modified CLT building envelops satisfied with a passive standard are used for 10-story building, the required insulation was decreased by $40.89m^3$ for a floor ($105.27m^2{\times}2.3m$ in height) compared to concrete building. As the number of floors increases, about 3.58 m3 of insulation per floor was additionally saved.

Current interior lighting design way that is consisting uniformly by designer's experience or simple capacity calculation diversifies according to standard of living elevation and there is problem that do not reflect been individualising resident's change request in lighting plan, design properly. Therefore, because this resident's request, enough judgment data that is worth reflecting dissatisfaction item in design concretely or standard is not saved up in business post, had gotten into bottleneck at lighting design. Diagnose resident's consciousness and feedback degree about interior lighting to existent apartment complex in this research and examined improvement plan. As a result, in the case of illumination, wanted higher brightness and showed reason that is most Affirmativ about order way of lighting fixtures. The reason is because can select registration nine that want by oneself directly. Plan qualitative elevation of house lighting environment making lighting image which is coincided in our real condition, and is thought to reflect various resident's character, fondness in design and solved dissatis faction.

아파트시장의 환경변화와 소비자 특성의 변화로 인해 아파트 선택시 소비자의 구매의사결정도 과거와는 매우 다른 양상을 보이고 있다. 아파트 건설업체들은 고객만족도를 높이기 위해서는 주거환경을 이해하고, 차별화된 주거가치를 고객들에게 제공하여야 한다. 그러나 지금까지의 선행연구에서는 주거환경이 주거가치, 주거만족, 재구매의도간의 관계에 대한 통합적 연구가 거의 없었다. 따라서 본 연구에서는 부동산뿐만 아니라 마케팅 분야의 관련 선행연구들을 토대로 주거환경이 주거가치, 주거만족, 재구매의도에 어떠한 영향을 미치며, 이러한 주거가치와 주거만족은 재구매의도에 어떤 영향을 미치는지를 분석하여 향후 아파트 건설업체의 경쟁력 강화를 위한 유용한 전략적 시사점을 제공하고자 하였다.

Apartment Buildings have particularity to cluster together, especially, floor is close to resident, it is subject to dissatisfaction about impact noise between up and down floors. However, we require standard for counterplan to reduce the impact noise of floor. In point of fact, it difficult to objective evaluate for performance sound insulation that not physical sound volume but orignal form, means and effect of sound caused to complex noise in apartment house. Unique type of dwelling and structure pattern cause to noise of floor impact which is established by law for standard regulation. It is object to analysis and compare the result of performance sound insulation of upper floor impact and sample construct the subject resilient material of sound insulator

From 1998, the number of household who live in apartment house outnumber that of household live in detached dwelling by 0.3% in Korea. As walls and floors are shared with neighbourhood in apartment houses, percent complaints to the impact noise from the upper floor was so high that it represents an important factor in apartment indoor noise. And the rate is closely correlate with children's running, playing and jumping. In this study, comparisons of standard impact source, such as Tapping Machine and Bang Machine, with real life impact sources were made in order to investigate acoustical characteristics between them. Also reproducibility tests for impact sound sources were carried out.

공동주택의 양적인 팽창에 주력하는 과정에서 품질관리 미비로 발생하는 하자문제는 입주자에게 정신적${\cdot}$ 경제적 피해를 끼치고 건설업에 대한 불신을 가중시켜, 주택공급자와 주택소비자간에 분쟁을 빈번하게 발생시키고 있다. 공통주택 관리령에 명시된 하자의 범위와 책임보증기간은 정량적 개념이 부족하고, 하자보증의 개념도 포괄적으로 구성되어 있어서 하자여부와 보수범위에 대한 견해차가 크다. 이로 인해 하자보수 종료처리가 원활하게 이루어지지 못하고 사회적 소모비용만 증가시키고 있다. 이에 대해 본 연구에서는 주택공급자 측면과 주택소비자 측면에서 하자보수 종료에 대한 합리적인 방안을 제시하고자 하였다. 아울러 원활한 하자보수 종료를 위하여 각 주체별 업무와 역할을 제시함으로써 하자보수 종결후의 유지관리를 향상시키는데 기여하고자 하였다.

This study aims to evaluate noise emission from water supply and drain installations in apartment bathroom. These noise were one of the most annoying noise sources in apartment houses. Especially, drain plumbing system have used bellow bathroom ceiling, it was very discomfort to hear the noise in bellow apartment. Noise of closets and faucets were measured which were main noise source, then these noise were evaluate and analyzed the emitting characteristics varying the supplying water pressure. As increasing the water pressure, also total noise level of the water supplying stool noise and faucet noise were increased. Especially the water closet showed remarkably the increasing noise level in middle and high frequency bandwidth, while the noise level of faucets increased in $50\;Hz{\sim}250\;Hz$ of low frequency bandwidth. Vortex closet were favorable to syphon closet, and lever faucet were favorable to conventional lavatory faucet on reducing the noise. Above these results could be used in basic data establishing KS (Korean Standard) for evaluation and rating procedure and measures reducing these noise.
