    To develope concrete panels suitable for the snow melting system based on renewable energy or unused temperature difference energy, highly thermal conductive concrete panels using silica stones were made. Through the comparative small-scale experiment between the general concrete panel and the highly thermal conductive concrete panel using the low temperature heat source device simulating the unused temperature difference energy, we verified the possibility of the highly thermal conductive concrete panel to maximize efficiency of snow melting system using low temperature heat source. - COLLAPSE

    We built a database of high-performance buildings and energy-saving technologies of the domestic and foreign countries. Futhermore, we selected major energy-saving technology from high-performance building and technologies DB. Energy-saving technologies comprising 15 cases were categorized into passive, active, and renewable energy systems. We analyzed the contribution of each technology in reducing the primary energy consumptions by using EnergyPlus v9.1.0 dynamic simulation tool. The structuring of the high-performance buildings and energy-saving technologies database, part of the “Development of building energy integrated support system for the spread of low-energy building”, will facilitate web-based database searches and help users increase their understanding of high-performance buildings and energy-saving technologies as well as improve their knowledge level. It will also contribute to the Korean government's reduction of greenhouse gas emissions in the building sector and the improvement of building energy performance in Korea through the analysis of the effects of building energy such as primary energy consumption and energy savings strategies. - COLLAPSE

    A model for predicting the supply air flow rate in the fan, which plays a important role in HVAC system, is to be developed using artificial neural network. A predictive model has been developed to study with the Levenbarg-Marquardt algorithm through 8760 sets of one-hour resolution. The model of three cases was constructed according to the combination of the input variables constituting the input data of the neural network, and the accuracy of each case model was evaluated through statistical approach using Coefficient of Variation of Root Mean Square Error and the best performance model was determined. The input parameters includes flow rate, pressure, fan power consumption, outdoor air temperature, outdoor air humidity, supply air temperature and zone air temperature. The suggested model including seven input data shows the best performance. The results show that the developed model can provide results sufficiently accurate. - COLLAPSE

    Based on policy for the energy saving of the building sector, the energy performance index for the building envelope and the results according to the standardized test method are evaluated based on performance criteria. The energy-related performance evaluation method of the building envelope utilizes the performance index such as the thermal conductivity. Considering the time and the cost, the influence factors to evaluate energy performance are extremely limited. Therefore, we propose a calorie calculation methodology to evaluate the heating and cooling energy performance of a building envelope using an outdoor laboratory that can simulate buildings exposed to actual environmental conditions (radiation, temperature, humidity, wind speed, etc.). Energy performance evaluation of the exterior of the building using the outdoor space unit. This paper presents energy performance evaluation method of building envelope using outdoor space unit test room and evaluation of heating energy performance of glass specimen. The energy performance of the building envelope can be compared by calculating the input heat quantity according to the temperature difference range of the inside and outside of the test room. - COLLAPSE
