Small building facilities can be combined with various systems, but other concepts that can be considered as alternatives to energy-saving facilities system composition through system application and instrument performance analysis are heat pump systems, hot water systems, and ventilation systems. Relative strengths and weaknesses were compared in terms of comfort, humidity control, energy efficiency, required space, and management control. In terms of the applicability of residential and non-residential applications, energy efficiency and comfortability, it is expected to be positively converted to an integrated air-conditioning and heating ventilation facility. It is believed that it will need to analyze the processing load mode for integrated facilities that are expected to be applied to small buildings in the future and evaluate the period energy efficiency of consumption energy compared to treatment energy.

The purpose of this study was to propose a synthetic envelope thermal performance for small-scale buildings to satisfy the building energy efficiency grade 1++, which is the standard for zero-energy building certification. It was found that the correlation between the average heat transmission rate by wall area and the heating energy demand was very low. And the correlation between the average heat transmission rate by floor area and the heating energy demand was very high. Therefore, it would be desirable to apply the average heat transmission rate by floor area as the synthetic envelope thermal performance. Design conditions for the primary energy consumption to be less than 140kWh/m² should satisfy the average heat transmission rate by floor area of 0.45W/m²K or less, and install renewable energy when it exceeds 0.45W/m²K in the Jungbu 2 area

Energy loss from windows accounts for large scores of heating and cooling loads also in energy saving apartments that is reduced over 30% of total energy consumption. Movable reflective insulations, insulation shutters, blinds, insulated shades are used to reduce energy loads from windows. In this study, energy saving performance of insulated shades was simulated by control methods. According to installation of insulated shades, heating loads were decreased about 10.5∼11.3%, and cooling loads are decreased about 29.1∼38.3% on an energy saving apartment. The heating peak load was reduced about 9.5% by insulated shades and the cooling peak load was reduced about 25.7∼31.5%. In the case of insulated shades with automatic control system, simple time schedule control system would be more efficient than outdoor detection control system that should use several sensors.
