Reducing the energy required for heating, cooling and air conditioning is a very important factor in reducing overall building energy. Efficient design of building energy, such as estimating the capacity of equipment suitable for the size and purpose of the building, is an important factor to reducing building energy. Accordingly, it is necessary to accurately calculate the heating and cooling load suitable for appropriate size in order to save energy for heating and cooling. However, in the case of small buildings, most of the equipment is selected by converting it into the capacity of the air conditioning equipment per unit area. As mentioned above, equipments are being installed without considering building characteristics such as location, orientation, window area ratio, and thermal transmittance. Therefore, it takes a lot of time to calculate the load, and it takes a lot of time to change the design. For these reasons, this study developed a Heating and Cooling load evaluation program that non-experts can use easily. To verify reliability, this document tried to review the adequacy of the heating and cooling load evaluation by comparing the error with the existing program and examining the error according to the difference in the heating and cooling load evaluation unit. Through the results of this study, it was confirmed that it is possible to induce the appropriate heating and cooling load calculation through developed program that reduces the input items of the building’s envelope. |
