The purpose of the study was to set up reference buildings based on the apartments design status and the National Statistical data, and to calculate the energy consumption of the reference building by simulation program. In addition, the energy consumption of apartments including the energy consumption by appliances consumption behavior was calculated. We surveyed the design data of 174 apartments which were granted building permission from 2010 to 2014. The energy consumption of the reference building was divided into heating, hot water, lighting and was calculated using the ECO2 simulation program. Home appliances calculated energy consumption by heating, cooling, hot water, cooking, lighting, and white & brown goods. The results show that the total annual energy consumption of reference building is 18,266.8㎾h/y. The composition percentages are 58.4%(10,659.2㎾h/y) for heating, 16.5%(3,018.1㎾h/y) for hot water, 13.1%(2,397.6㎾h/y) for cooking, 7.2%(1,318.7㎾h/y) for lighting, 3.4%(622.4㎾h/y) for home appliances and 1.4%(250.8㎾h/y) for cooling. The annual energy consumption unit of the reference building was estimated as 214.93 ㎾h/㎡·y.

In this study, we will review the EPIs of the office buildings that are both approved for construction and rated by the building energy efficiency rating system, compare and analyze them in terms of items and means with those that are approved but not rated, and eventually define their characteristics. We targeted office buildings that are rated at 1st degree in efficiency and collected building energy-saving proposals and the EPI review reports that are approved in general to analyze the scores the buildings achieved in the four EPI categories: architectural, mechanical, electrical, and renewable energy. Data on 67 office buildings led to the following results: 22 approved in 2011 and 45 not rated by the efficiency rating system. The EPI scores in the four categories were added to produce the means in each category: the approved buildings scored 82.3, which is 18.5 higher than 63.8 for the disapproved buildings. The 1<SUP>st</SUP> evaluation of the rated buildings’ energy consumption resulted in 140.4~299.8 kWh/m2 year with a mean value of 243.2 kWh/m2 year. For the buildings approved (77%), high-efficiency appliances and renewable energy products were applied. The lighting density ranged from 11?14 W/m2, with a mean value of 2.4 for both the approved and disapproved buildings. In the architectural approval stage, when one writes energy-saving proposals and EPIs of office buildings, we expect the results of this study to provide base data to help in reviewing the design alternatives for energy saving.

The evaluation items of the rated buildings were as follows (the values for each class are given after the item): basic household window and balcony window performance ? 1st class: 2.4W/㎡?K, 3.3W/㎡?K, 2nd class: 3.01W/㎡?K, 3.22W/㎡?K, 3rd class: 3.26W/㎡?K, 3.55W/㎡?K; expansion type household window, balcony window, and expansion-type window performance ? 1st class: 2.79W/㎡?K, 2.75W/㎡?K, 1.87W/㎡?K, 2nd class: 3.13W/㎡?K, 3.16W/㎡?K, 2.01W/㎡?K, 3rd class: 3.2W/㎡?K, 3.3W/㎡?K, 1.96W/㎡?K. The results from the analysis of thermal conductivity and thickness, both factors in evaluating wall insulation are as follows - 1st class: exterior wall 0.031W/m?K, 74㎜, sidewall 0.031W/m?K, 102㎜, core wall 0.031W/m?K, 55㎜, 2nd class: exterior wall 0.034W/m?K, 66㎜, sidewall 0.034W/m?K, 96㎜, core wall 0.034W/m?K, 48㎜, 3rd class: exterior wall 0.034W/m?K, 66㎜, sidewall 0.033W/m?K, 93㎜, core wall 0.035W/m?K, 48㎜. The third item for added saving in unit households (installation of automatic thermal controller per room or per zone) was evaluated that the system were applied to 197 blocks.

This study aims to evaluate the heat transfer characteristics and energy consumption in the wet and dry ondol systems. Conditions of the continued heating mode set the indoor temperature at 20℃ and hot water supply temperature at 60℃ and 70℃ for 3 days. The scheduled heating mode operates heating at 6~9am (room temperature at 20℃), suspends heating at 9~18pm (out mode), and runs heating at 18~24am (room temperature at 20℃) and 24~6am (room temperature at 17℃) for 2 days. The results from the continuous heating mode in the dry/wet ondol systems confirmed that the dry and wet systems had the same average indoor air temperature (18.9℃) and similar energy consumption. In addition, the results from the scheduled heating mode in the dry/wet ondol systems confirmed that the dry ondol system had lower energy consumption than the wet ondol system. Therefore, the scheduled heating mode in the dry ondol system is expected to reduce energy consumption.

N,N'-dimethylethylenediamine-N,N'-di-${\alpha}$-butyric acid(dmedba)와 세자리 아미노산과의 코발트(III) 착물인 [Co(dmedba)(L-aa)] (L-aa = S-methyl-L-cysteine, L-methionine, L-glutamic acid, L-aspartic acid)는$ s-cis-[Co(dmedba)Cl_2]-^ 착물과 아미노산과의 반응으로부터 얻었다. 아미노산들은 [Co(dmedda)(L-dd)] 착물과 같이 아민과 카르복실그룹을 통하여 배위되었다. 이 착물들의 구조는 ^1H-NMR, IR, UV$ 스펙트럼 데이타와 원소분석으로 확인하였다. Cobalt(III) complexes of N,N'-dimethylethylenediamine-N,N'-di-${\alpha}$-butyric acid(dmedba) and trifunctional aminoacids, [Co(dmedba)(L-aa)] (L-aa = S-methyl-L-cysteine, L-methionine, L-glutamic acid, L-aspartic acid) have been prepared from the reaction between the $ s-cis-[Co(dmedba)Cl_2]-^$ complex and the amino acid. The amino acids have been found to coordinate through the amine and carboxylate groups just like [Co(dmedda)(L-aa)]. The complexes obtained in this work were characterized by their proton magnetic resonance, infrared and visible absorption spectral data along with the elemental analyses.
