  • Recently available heat pump system by using air heat-source is not efficient. Because the mean temperature of korean winter season is low, economy of air heat-source heat pump descend, and COP is below 3.0. This paper was practiced the simulation on evaluation criteria for heat pump heating and cooling systems to resident building. As a result, heating and cooling composition heat pump system apply to the building needed to be provided heat source for 24 hours.

  • This study analyzed the energy consumption of a building pump system that was originally equipped with a primary-secondary zone pump system. Using the HYSYS program the energy consumption of the primary pump system was compared with the primary-secondary zone pump system. The primary-secondary zone pump system consumes less energy than the originally designed primary pump system. When the distance between the machine room and each building is assumed to be equal, the primary pump system can be more efficient than the primary-secondary zone pump system with decreasing the distance. When the distance is 120 m, the primary system consumes less total annual energy than the primary-secondary zone pump system and saves 2,773 kWh. The suggested energy evaluation program can be useful if the designer seeks a more efficient pump system.

  • In the present study, the simulation on the annual performance evaluation of a renewable energy systems with fuel cell driven compound source hybrid heat pump systems is applied to the heating and cooling of large community building. The large community building has the economical advantage to apply heat pump cooling and heating systems the long period operation. If air and ground source hybrid heat pump systems are combined, COP of the system can be increased largely. Fuel cell driven compound source hybrid heat pump system can reduced the fuel cost as well as thermal storage tank sharply.

  • There are so many related policies to design and construct building mechanical system. Therefore, preferentially in this study, purposes and major contents of related laws are summarized briefly. Subsequently, some points at issue and ways to improve laws and codes for energy conservation are suggested. From the results of this study, some points at issue are as follows : (1) Inconvenience in the application due to dispersion of similar codes. (2) Lack of systems and tools to verify and to evaluate the effect of energy conservation by any policy (3) Lack of the incentive Policy for Participator to conserve of energy.

  • Increasing wages and decreasing skilled labors are problems awaiting solution. The development of automatic technologies contributes to accelerating the one of construction automation. Thus, this study is to suggest the way to develop the automated building construction system base on one performed in Japan in order to solve urgent problems of construction industry in Korea. Therefore interviews and questionnaires were performed based on experts who work for the automated building construction system field and analyzed through analytic hierarchy process. In doing so, it was the most important factor to develop a branch of automatic, mechanical or machine technologies for the automated building construction system. Especially the study indicated the importance of the technologies to substitute skilled labors such as a robot. This research could contribute to developing the automated building construction which is very unique and suitable for construction industry in Korea.

  • This study derives quality checking items in Building Mechanical Systems Design Criteria, and suggests quality criteria to review BIM models in the duct system of an air conditioning system for rule-based automatic checking. First, components for the duct system of an air conditioning system were reviewed, and the quality checking items were drawn from Building Mechanical Systems Design Criteria, through assessment according to object, attribute and relationship composing the BIM model. Second, quality checking types were derived, by analyzing the quality checking items and Rule set of the Solibri Model Checker. Finally, methods of algorithm functioning for checking the BIM models for mechanical systems in computers were drawn, and Elements to comprise the quality checking criteria (rule) were suggested. This study means that that checking items are derived from domestic criteria, and a way for the development process of determining quality checking criteria (rules) is suggested.
