Abstract
There is a great interest in building information modeling (BIM) and energy saving worldwide. In reality, however, insufficient studies have been conducted on the development of design methods to perform energy performance analysis. Thus, there is a problem that it is difficult to objectively obtain reliability in energy performance assessment of architectural designs such as scale and size of buildings. In addition, the energy performance analysis is considered as a different field from eco-friendly design methods, and there is another problem that low-carbon design methods more dependent on thermal insulation performance and heating ventilation and air-conditioning (HVAC) system than on original design methods are mainly developed. In order to solve this problem, this study aims to develop design methods capable of considering energy performance from the early design stage. Designers are required to intuitively understand the results through energy performance analysis using BIM tools and to reflect them in design. To this end, this study analyzed the correlation with energy performance using only basic architectural design elements with mass buildings. This has the advantage of establishing more free mass design mass design considering energy performance even if design and main structure are yet to be determined.
Highlights
There is a growing awareness of environmental pollution in the whole field of architecture, and there is a continuously increasing interest in green building and lowcarbon design methods
According to the Korean Statistical Information Service (KOSIS) in Statistics Korea, buildings account for approximately 9.5% of the overall energy consumption
Many studies related to the development of design methods for energy saving have been carried out, little research has been conducted on design elements such as building form, and most studies focus on exterior design elements such as awnings and electrical and mechanical equipment [3]
Summary
There is a growing awareness of environmental pollution in the whole field of architecture, and there is a continuously increasing interest in green building and lowcarbon design methods. The increase in energy consumption showed a decreasing trend from 2010 to 2015, the total energy consumption has continuously increased. It is considered that the total energy consumption will continuously increase in proportion to the progress of energy efficiency in buildings through the system as demands and expectations for comfort and convenience of buildings increase according to changes in residents’ life patterns and awareness. Apartments account for the largest proportion of the energy consumption, 17.2% in 2015. The energy consumption in apartment houses and business facilities showed a continuously increasing trend accounting for 32.9%, and there is a need for a system plan for energy saving of buildings because they account for one third of the overall energy consumption [1]
