Architectural market in the world is trying to develop Zero Carbon Buildng that doesn"t use fossil fuel. Residential building that thermal load such as heating and domestic hot water is over 70% in energy consumption is easy to make Zero Carbon Building compared with office building that is mainly electric load. So, As a preliminary for analyzing the effect of Solar thermal system in the building, an annual energy consumption of residential building and total heat loads are calculated. Based on this result, three alternatives of solar thermal system for hot water and heating are applied in the building while installation area is increasing. Solar thermal system is applied on balcony and roof of apartment building as the way to reduce thermal load. In the first case that solar thermal system for hot water is applied on the balcony, optimum installation area is $56m^2$. And you could install $40m^2$ of this system in the roof that angle is $30^{\circ}$. In the second case of solar thermal system for heating and hot water, you can install $40m^2$ on the roof. As a result of economic evaluation, the most economical application method is to install $40m^2$ of solar thermal system for only hot water on the roof of the building. At that time, you can payback the initial investing cost within 10 years. And carbon emission of this method can be reduced until about 4 ton per year.

This research suggests the most effective way for improving energy efficiency in tall buildings is a "fabric-first" approach. This involves optimizing the performance of the building form and envelope as a first priority, with additional technologies a secondary consideration. The paper explores a specific fabric-first energy standard known as "Passivhaus". Buildings that meet this standard typically use 75% less heating and cooling. The results show tall buildings have an intrinsic advantage in achieving Passivhaus performance, as compared to low-rise buildings, due to their compact form, minimizing heat loss. This means high-rises can meet Passivhaus energy standards with double-glazing and moderate levels of insulation, as compared to other typologies where triple-glazing and super-insulation are commonplace. However, the author also suggests that designers need to develop strategies to minimize overheating in Passivhaus high-rises, and reduce the quantity of glazing typical in high-rise residential buildings, to improve their energy efficiency.

The purpose of this study was to carry out land use suitability analysis of Seoul Metropolitan City based on ecopolis planning concept or environmentally sound and sustainable development. Objectives of the analyses were to save energy by increasing urban density and allocating urban land use types near to public transportation system, to increase food producing capacity by restoring fertile agricultural lands, and to enhance urban ecosystem by expanding and networking parks and green spaces. This study has two phases. First, the land use suitability analyses for commercial, industrial, residential, agricultural, and green spaces were carried out. Second, required urban land use .types were allocated based on ESSD concept. Two alternative land use plans were developed based on two population sizes:existing population of 11million and 4.4million derived by the application of ermergy theory of T. Odum.

Purpose: The energy consumption of apartment units is affected by the lifestyle of the residents rather than system technology. In this study the numerical analysis of assumed energy consumption correlation factors with arbitrary value due to uncertainty. It is intended to be used as a simulation correction value which can be utilized as a predicted value of actual energy usage. The correction value of the simulation is set in the developed form of the existing process that derives the actual usage amount. The simulation results used in the existing evaluation system are used to maintain the useful value as the current system evaluation scale and predict the actual capacity. Method: The method of the study is to statistically analyze the data frames of all complexes capable of collecting the annual energy usage and to reconstruct the population by adding the variables that are expected to be correlated. Repeat the data frame configuration with variables that are assumed to be highly correlated with energy use levels. Determine whether there is correlation or not. The intensity of the external characteristics of the building equipment related to the energy consumption is presented as the quantitative value. Result: The correlation between electricity consumption and trading price since 2010 is analyzed as (Correlation coefficient 0.82). These results are higher than (Correlation coefficient 0.79), which is the correlation between residential area and trading price. This paper signifies the starting point of the methodology that broadens the field of view of verification of simulation feasibility limited to the prediction technique focused on the simulation tool and the element technology scope.The diversified phenomenon reproduction method develops the existing energy simulation method.It can be completed with a simulation methodology that can infer actual energy consumption.

In order to overtake a quantitative analysis of effect of anthropogenic heat and different land-use on urban thermal environment numerical simulation of surface energy budget was carried out under typical summer synoptic condition. It is beneficial to understand surface temperature of complex urban surace. The different land-use types are classified of rice field farm fruit garden residential region forest water and swamp by using map scaled 1/25000 of Pusan metropolitan. The model predicts that maximum heat island intensity in the central part of Pusan is 7$^{\circ}C$ at 2000 LST in summertime. The surface temperature is propotional to the density of constructions. The effect of anthropogenic heat generation on surface temperature is the increase of 0.3$^{\circ}C$ at 1400LST in the central part of Pusan during summertime.

In this paper, traditional residential architecture in South Korea appear to approach environmental regulation as part of ecological architecture of regional climate controlled environment, according to the characteristics and spatial arrangement, and material to the environment was described as a controlled manner. The scope of this study was not large scale housing construction from traditional chusagotaek, yunjeunggotaek, yangjindang, dokrakdang target was the case. Focusing on examples extracted from Korea first eco-friendly characteristics of traditional residential architecture is an extension of nature to explore space and yard space, and South Korea by way of environmental control that appears in traditional architecture, waterproof, moisture, solar radiation, sunlight, ventilation and air Attributes such as environmental regulation and environmental regulation of space, place and manner of materials were described. Korea's research through more traditional residential architecture of the environmental control and a wide range of environmentally friendly eco-construction was that appeared natural to use energy efficiently, it had been available. Later appeared on the Korea traditional architecture through research on environmental control of environmentally friendly ways to navigate and take advantage of the elements, through continuous research and eco-friendly construction to realize the traditional South Korea could provide a prototype of the modern, I thought I'd had.
