At the time when zero energy building is expected to be generalized, this study examines whether the investment in the passive element or the active element is more effective in terms of energy in the construction process of zero energy building. In other words, the effect of energy demand by passive element and the change of energy generation by active element are examined in terms of the same investment cost. The purpose of this study is to examine the change of energy demand by passive element and the change of energy generation by active element in zero energy building and to make reasonable investment decision by comparing energy with cost aspect. For this purpose, we selected the buildings to be subjected to energy simulation and derive the required energy amount and energy generation amount by using meteorological data of four regions in Korea. The change of energy demand and energy generation according to the change of application condition was derived. In order to compare and analyze the changes in energy demand and generation at the same cost standard through price survey and quotation of window and photovoltaic power generation equipment.

The purpose of this study was to consider the energy generation of the building as well as the energy demand of the building in terms of zero energy building design. The reason why the zero energy building viewpoint should be discussed is that direction of the building, heat transfer rate of the building, and the S/V ratio of the building are variables related to energy demand and solar panels installed on the building roof and building envelope are variables related to energy generation. This study proceeded as follows; Firstly, the simulation model of large office and elementary school has the same mutual volume and total floor area, and the each floor area and number of floors are adjusted so that the S/V ratio is different. To the next, the energy demand and energy generation of the simulation model were derived based on the meteorological data of Seoul, Daejeon, Busan. Finally, energy demand, energy generation, and final energy demand were compared with heat transfer rate, S/V ratio, building type, region, and orientation. The results of this study is that consideration of solar power generation in terms of energy generation should be taken into consideration at the same time in consideration of the heat transfer rate, the shape, the region and the direction of the zero energy building design.

Building energy savings has been selected as a major goal of achieving national greenhouse gas reductions. The Zero energy building minimizes the energy load of buildings by maximizing insulation performance and minimizes energy consumption by utilizing renewable energy such as solar power. However, it is possible to manage the construction of newly constructed buildings as zero energy buildings, but it is true that the improvement of the energy performance of the existing buildings is insufficient. And there are many difficulties in the refurbishing passive elements and active elements of existing buildings. Therefore, in this paper, we tried to compare the effects obtained by replacing HVAC facilities and renewable energy facilities that are easy to apply to existing buildings. In the process, we connected the renewable energy with the battery energy storage and implemented the DC distribution by applying the appliances using the DC power.

Thermal performance tests of solar thermal collectors include determination of coefficient parameters in an efficiency equation. The parameters can be estimated using regression method to minimize an objective function as sum of differences between measured efficiency data and regressed efficiency equation. However, this conventional approach doesn't consider measurement uncertainties. In this presentation, a method to determine regression parameters in the efficiency equation and uncertainties of the parameters is described with mainly mathematical expressions based on literature reviews. In the method, parameters in the equation for collector efficiency can be determined using regression analysis with a weighting factor in the objective function. The weighting factor can be uncertainties of the differences between measured and fitted efficiencies. To evaluate the approach, performance estimation of a solar collector using the efficiency equation with uncertainties is compared to the result using the conventional efficiency equation by a simulated way for a case in one of previous studies.

The building ages after the completion of its service life after completion, and its usability gradually decreases. Therefore, it is necessary to diagnose a building that accurately grasps the deterioration of usability and causes and problems. In this study, in order to minimize the inconvenience of building users and to prepare an improvement plan to maintain the initial performance of the building, a method for evaluating building diagnostics in the aspect of the building environment was established and the process was conducted for pilot buildings. To secure the validity of the evaluation method, the improvement plan derived from the building diagnosis was applied to the building and the improvement results were analyzed. As a result of applying the improvement plan, the thermal and light environment of the building was improved and the usability of the building could be improved.
