Buildings are responsible for 30~40% of energy consumption and CO2 emissions. Energy performance of buildings is key to achieve the energy saving objectives, namely the reduction of a 20% of the greenhouse gases emissions. In Korea, building energy efficiency rating has been issued and is considered as an important way to achieve the agenda of the green growth. Experts such as energy assessors in EU are essential in order to improve the energy performance of buildings and the professional accreditation system is a cost-effective way of fighting against climate change and improving energy security, while also creating job opportunities, particularly in the building sector. In this paper, we conducted the online survey to investigate the need for professional accreditation system of building energy efficiency rating.

Recently, we know that stack effect in high-rise buildings causes various problems in winter such as elevator malfunctions, difficulties in opening and closing. Many studies have been done on the problems caused by the stack effect in office buildings, and several guidelines and solutions have been proposed by drawings reviews and airtight constructions. However, stack effect problems have occurred in existing buildings because they were not applied at the design stage and the construction one. To reduce the problems caused by stack effect after construction, we need to understand the overall airflows in the buildings through the pressure profile analysis. This paper deals with field measurement of pressure distributions and analysis of stack-induced problems in the existing high-rise office building.

It is often assumed that the characteristics of airtightness of high-rise residential buildings are similar to those of typical detached houses. In high-rise residential buildings, however, air leakage happens not only by the exterior windows but also by the interior walls between dwellings. Moreover, there is many factors that have influences upon the air leakage in high-rise building. Therefore, it is important to know the air leakage data or the criteria of leakage of residential units to estimate the energy loads. This paper presents the airtightness characteristics of dwelling units in two high-rise residential buildings and the limited conclusions that can be drawn from these data. Based on the measurement data, the main cause of the airtightness distinction between two residential buildings is due to the different envelope types.

This study sought to consider the abstract of sport for all and draw the practical plan and logic for the participation of persons with disabilities in sport for all by comparing sport for all for persons with disabilities with sports for normal people. In particular, this study examined the concept of sport for all and what it means to persons with disabilities as well as the realities of sport for all for persons with disabilities and the basis of problems such as sports organization, budget, circles, institutions, instructors, programs, sports competitions, etc. Based on the results, a main activating plan was suggested as follows: 1. There should be a specific organization that will be fully responsible for sport for all. 2. The budget from the government should be expanded. Likewise, a very special financial plan such as donations, financial support, etc., should be considered. 3. The government should lead efforts to organize circle activities and try to activate local circle activities. 4. Persons with disabilities should use common facilities freely together with normal people. At the same time, local facilities should be built especially for persons with disabilities. 5. Instructors who have majored in adapted physical education should be arranged for persons with disabilities. In addition, a new qualification system should be established for them. More opportunities should also be given to special athletes. 6. A program especially designed for persons with disabilities should be developed. 7. The government should consider expanding its support for sports competitions for persons with disabilities. It should also devise ways and means to enable persons with disabilities to participate in athletic meets for normal people.

Recently, complex commercial buildings(ex, department store) experienced stack effect problems during the winter such as excessive indoor upward flow around escalator areas. The main objective of this paper is to investigate the problems of indoor airflow caused by stack effect in retail facility and to propose solutions for stack effect problems during the cold season. Building manager interview, drawings review, and walk-thru audits were conducted in existing department store. After several meeting, possible solutions and countermeasures in terms of architectural and mechanical views were proposed for reducing problems due to the stack effect. Air-tightness constructions and separation method such as installing an 'air-lock door' around the escalator area on the top floor where problems associated with airflow speed occur, are suggested and evaluated using network simulation program.
