The present study has been conducted to find the critical factors of energy saving for 「2030 green design code for buildings in Seoul」. To save energy use in buildings and reduce greenhouse gas emission rate, Architecture Planning Division of Seoul Metropolitan Government is preparing to enforce 「Total energy use restriction for building s」. This study is an initial analysis to find the critical factors in saving energy used by buildings. Energy simulation for an apartment and an office was conducted, and the critical energy saving factors were extracted. For apartment the direction of the building, conduction rate of the wall and window were important, for the office lighting, window/wall ratio, HVAC system, and equipment efficiencies were significance in saving energy.

Korean traditional palaces were built with big budget by the best craftsman of the time. Also the best architecture environment control technology was applied. Since many studies are done on Indoor Air Quality in and out of Korea, it is possible to adapt traditional technologies from the past to modem buildings. The purpose of this paper is to measure the indoor air environment control technologies of the palaces and do the background study to modernize traditional technology. Air flow performance was measured by tracer gas method, and natural ventilation was measured by the indoor air velocity and the surface temperature of the frontside and backside temperature. The air flow performance of 'MeanGa' and 'ChimJun' type buildings were 1.65~2.96n/h and 0.63~2.14n/h compared with 0.13~0.32n/h of modem apartments, which shows controlling air flow performance was more flexible in traditional palaces than In modem buildings. Natural ventilation occurred fluently with different wind directions. The surface temperature difference was 10~14℃, which means gravity ventilation is possible. I purposed ideas to modernize traditional architecture environment control technology based on the study.

The demand for renewable energy systems in buildings are increasing to save energy, to satisfy the renewable factor regulation, and to build a sustainable building. Each building has a distinct load profile and renewable energy resources, so the optimized portion of using renewable energy is each building is always different. To find the optimized renewable energy system, the engineer uses building energy simulation tools which are not good at comparing many systems, and hard to learn. In this study MORE-B(Model for Optimizing Renewable Energies in Buildings) is developed to analyze many renewable energy system cases on energy, renewable factor, net cost, and CO2.. To analyze many cases, the study suggests fast and efficient formulas and algorithm for MORE-B. Then it will be compared with EnergyPlus and HOMER for verify the corectness of MORE-B. Finally some examples of case studies done by MORE-B will be shown.

The purpose of this study is to investigate the characteristic of energy consumption in apartments equipped with ventilation system and to analyze the energy consumption of households using ventilation system. As a result of investigation, the number of households using ventilation system is 47, and the number of households not using ventilation system is 99 out of 146 households. And households was classified by the number of residents, as a result, the energy consumption of households using ventilation system is higher than households not using ventilation system. (P<0.05) And households was classified by the area of the residence, as a result, the energy consumption of households using ventilation system is higher than households not using ventilation system only in 92㎡ house. (P<0.05) And energy consumption was classified by the heating and cooling, as a result, there are no difference the energy consumption of households using ventilation system between households not using ventilation system.

Many studies were researched by indoor environment, such thermal environment and subjective responses, airtightness, a traditional house in korea. However these studies are not enough to evaluated characteristic of indoor air environment in traditional house. The purpose of study are to investigate Airtightness of different build years, material and floor plan located four Royal-palaces in seoul. The airtightness in royal palaces were measured in during a day and these were measured by tracer gas method. we measured airtightness of total 7 building. As a result, royal palaces of airtightness are researched 0.6~2.96. And recently builded Gandnyeongjeon of airtightness is 0.6 in An-bang.

HVAC&R(Heating, Ventilation, Air Conditioning & Refrigeration) system consists of components and equipment arranged in sequential order to condition the air, to transport it to the conditioned space, and to control the indoor environmental parameters of a specified within required limits. It is the most energy consuming building services representing approximately 50% of the final energy use in the building sector. The purpose of this study is to provide the energy saving strategies and it is a main target in the development of HVAC&R system design guideline. Although there is a large number of building simulation tools available, these tools are mainly used for thermal load calculations in view of sizing of HVAC&R systems. This work is to research and enable useful applications of HVAC&R energy analysis tool for the integrated low-energy building design support. This paper discusses the results of system impact assessment for energy consumption characteristic of office buildings. A prototype commercial building, a 37,000㎡ office building, was selected for the energy simulation and for each HVAC&R set, total 960 variables could be identified. The results of the analysis are presented as percent changes in total cooling and heating energy consumption from an established baseline.
