In this study, we survey the 2 buildings at the Central 1 and 8 buildings at the Central 2, which are divided by each climate region in the rural regions. Major heat loss factors are 47% loss of the outer shell including outer wall, roof , and bottom, 30% loss through window, and 23% loss through crevice wind. We analyze the energy simulation of ECO2 program to construct a zero energy building regarding village hall located in Jung Juk 4-le at Centeral 2. We simulate the primary energy requirement regarding village hall and the simulated results show the 265.3 kWh/m²･a and it may estimate `2` energy efficiency grade. The energy requirement regarding village hall is the 183.2 kWh/m²･a when the passive technology are applied in village hall. We research total amount of energy requirement in village hall when the passive and active technologies such as solar cell with 3kW and solar thermal with 20m², geothermal power with 17.5kW. The simulated results show the improved energy efficiency certification grade with 1+++ due to the reduced primary energy requirement with 73% when passive technology including 3kW of solar panel is applied and the energy independence rate is 54%, which is estimated to be 4th grade of zero energy buildings. The order of energy consumption are solar panel, solar thermal, and geothermal power under applied passive technology in the building. In order to expand the zero energy building, it is necessary to introduce the zero energy evaluation system in the rural region.

본 연구는 농촌주택의 에너지효율평가 등급을 산정하고 에너지요구량 및 소요량을 분석하여 에너지의 관점에서 합리적인 설계 및 에너지절감방안을 도출하는 것이다. 농촌주택 표준설계도 중 구조형식(목조, 조적, 철근콘리트조)과 규모(40～85㎡)를 기준으로 3종을 선정하여 ECO2, ENERGY# 프로그램으로 건축물에너지 효율등급, 부위별 손실량을 산출하였다. 농촌주택표준설계도 3개 유형에 대한 에너지 성능에 대한 평가는 등급용 1차 에너지 소요량이 189.3～238.7 kWh/㎡․a로 2등급에서 4등급으로 예상된다. 표준설계도 주택의 부위별 에너지손실은 환기 39%, 창호 33%, 외벽 14%, 지붕 9%, 바닥 5%순으로 발생하여 환기와 창호를 통한 에너지 손실이 70%이상 발생한다. 국토교통부 고시 제2015-1108호 건축물의 에너지절약설계기준 별표1의 외벽 등 구조체의 열관류율을 기준으로 환기를 위한 열회수형 환기장치 적용, 창 및 문의 열관류율, 조명밀도의 세 개의 분류에 따라 에너지효율등급에 미치는 영향을 분석하였다. 에너지효율등급에 가장 유리하게 작용하는 것은 창 및 문의 열관류율을 낮추고 조명밀도를 작게 하며, 열회수형 환기장치를 설치하지 않았을 때 3개 유형 모두 2등급으로 가장 낮은 등급을 확보하였다. 농촌주택 표준설계도에서 에너지 요구량은 난방 > 급탕 > 조명순으로 비중을 차지하고 있으며, 에너지소요량은 난방 > 급탕 > 조명 > 환기 순으로 비율을 차지하고 있다. 등급용 1차에너지 소요량에서는 난방 > 조명> 환기 > 급탕 순으로 비중의 순서가 바뀌게 된다. 농촌주택 에너지성능 및 품질확보를 위하여 농촌지역 에너지효율평가제도 도입 등 지원 정책이 필요하다.

The study analyzed the heat losses and the building energy efficiency grade by the energy simulation using the ENERGY# and ECO2 programs for the three types of Standard design of rural houses. It was calculated the energy efficiency rating by the ECO2 program for the rural housing standard design, and the energy demand and the energy consumption by each factor were compared and analyzed. And it analyzed energy consumption by element of each house by ENERGY # program. As a result, first in the evaluation of the energy efficiency grade of buildings by the ECO2 program, the rating for primary energy requirement for the housing newly built by the standard design of rural house is expected to range from 2 to 4 with 189.3 to 238.7 kWh / ㎡.a. Second, the energy loss of each part of standard design of rural housing occurs in the order of ventilation 39%, window 33%, outer wall 14%, roof 9%, bottom 5%, and energy loss through ventilation and window occurs more than 70%. Third, the most beneficial effects on the energy efficiency grade is obtained the lowest grade of all three types by 2 when the lowering of the window and door heat transmission rate and the lowering of the light density, and the heat exchange ventilation device is not installed. Fourth, in the standard design of rural housing, the energy demand is occupied by heating > hot water > lighting order, and the order of the weight is changed in order of heating > lighting > ventilation > hot water. Fifth, building energy efficiency assessment system needs to establish policy for fixing rural housing energy as a practical device to ensure energy performance and quality.

수자원 개발 및 관광자원 확보를 위해 플로팅 건축물 등의 기법 도입과 관광단지로의 접근 편의성, 해상교통 등을 고려한 지리적 입지조건으로 수상건축물의 필요성이 대두되여 새로운 건축유형으로 부상하고 있는 실정이다. 이에 본 연구는 새로운 건축유형의 플로팅 건축물을 설비 대안별로 에너지소비량 분석을 통하여 에너지 절감효과를 제시함으로써 플로팅 건축물 에너지 제로화를 위한 기초자료를 제공하고자 한다.
