Predicting how much energy to use is an important issue in society. However, it is more difficult to capture the usage characteristics of residential buildings than other buildings. This paper provides time series analysis methods for electricity consumption in a residential building. Temperature is closely related to electricity demand. An error correction model, which is a method of adjusting the error with time, is applied when a cointegration relation is established between variables. Therefore, we analyze data via ECMs with consideration of the temperature effect.

The demand of urban land in the Capital Region will be increased by the national economic growth of Korea. However, the available land for residential, commercial, and industrial should be limited in Capital Region, and the system of land supply for the urban land doesn't work effectively in the Capital Region. This research aims to forecast land demand in Capital Region based on the analysis of number of residents as well as housing units, and to suggest desirable land supply directions based on the analysis of land supply regulations and controls. This research concludes that it is demanded $293km^2$ of residential site for the construction of 1.27 million housing units by the year of 2010, and the change of land use from agricultural to residential is very restricted so that it may not supply urban land flexibly and appropriately. Thus, it is necessary to improve not only the system of land use controls but also cooperation among public agencies for the rational operation of land supply system.

Purpose - Considering the importance of housing needs to real estate market, domestic studies on real estate prices from the perspective of demand are basically based on macro-data, but relatively few are associated with micro-data of urban real estate demand. We try to find a reliable relation of elasticity of demand and commercial housing market. Research design, data, and methodology - In this paper, we have derived housing demand theoretic method and have utilized micro-data of residential family housing survey of downtown area in Kunming City in October, 2015 to estimate income elasticity and price elasticity of housing demand respectively and make a comparative analysis. Results - The results indicate that income elasticity and price elasticity of families with owner-occupied housing are both larger than those of families with rental housing. Income elasticity of housing demand of urban residential families in Kunming is far below the foreign average and eastern coastal cities level, however, the corresponding price elasticity is far higher. Conclusions - We suggest that housing affordability of urban families in western China are constrained by the level of economic development, and the current housing price level has exceeded the economic affordability and psychological expectation of ordinary residents. Furthermore, noticing the great rigidity of housing demand, the expansion space of housing market for improvement and for commodity is limited.

This paper investigates whether the use of Rainwater Harvesting Systems (RWHSs) to provide water for washing machines in Hong Kong residential buildings would be financially attractive. In such systems, rainwater is accumulated and reused for doing laundry, garden irrigation, flushing toilets, and even drinking. Thus, the analysis of RWHSs' financial feasibility is essential for construction projects. RainCycle is used to validate financial feasibility, considering particular circumstances and data relevant to the Hong Kong context. A range of different scenarios by adjusting three factors are evaluated: catchment area, water demand, and discount rate. It is suggested that $2,000m^2$ would be a suitable catchment area in a typical Hong Kong residential building and it is demonstrated how water demand and discount rate influence the financial performance of RWHSs. In particular, the financial performance of RWHSs is sensitive to discount rates. The results suggest that the RWH system would be worthwhile for buildings with a lower number of floors, but would barely achieve financial validation in Hong Kong's super high-rise residential buildings.

Electricity contributes to the development of the economy. Therefore, forecasting electricity demand plays an important role in the development of the electricity industry in particular and the economy in general. This study aims to provide a precise model for long-term electricity demand forecast in the residential sector by using three independent variables include: Population, Electricity price, Average annual income per capita; and the dependent variable is yearly electricity consumption. Based on the support of Multiple variable regression, the proposed method established a model with variables that relate to the forecast by ignoring variables that do not affect lead to forecasting errors. The proposed forecasting model was validated using historical data from Vietnam in the period 2013 and 2020. To illustrate the application of the proposed methodology, we presents a five-year demand forecast for the residential sector in Vietnam. When demand forecasts are performed using the predicted variables, the R square value measures model fit is up to 99.6% and overall accuracy (MAPE) of around 0.92% is obtained over the period 2018-2020. The proposed model indicates the population's impact on total national electricity demand.

Recently international marriage has been increasing steadfastly in Korea and its diversity of nationality has been expanding also. Korean government and academic circles are actively studying on such trends in population to find out proper measures to cope with such social changes. But their studies on improving the residential environment that is the base of the essential three factors of life, clothing, food and housing are not sufficient enough. Therefore it is necessary to study in depth and diversity about the residential environments of multi-culture families that are the base of their life. It is necessary to comparatively study the residential status and demands of these immigrants by marriage. The purpose of this study is to comparatively study the residential status and demand of immigrant women by marriage according to their nationalities. The objects of this study are the immigrant women by marriage from China, Vietnam and Cambodia who take the high portion of immigrant women in Jeonju-si and survey was used as study method. The result of this study revealed that the general characteristics, residential status and demands of immigrant women showed certain differences and the direction of residential plans for them in future based on these differences was proposed. This study is meaningful as basic information to improve the residential conditions of the multi-culture families in order to enhance their quality of life in preparation for the coming society of multi-culture.

The municipal water is directly related to the people's quality of life. To examine and implement reasonable water policies including management of the water demand and economically sound investment decisions, it is essential to estimate the conceptually correct and empirically valid economic value of water. This study attempts to estimate the consumer surplus and economic value of municipal water which is supplied to 16 cities in Korea using demand curve approach. The results indicate that the consumer surplus and economic value of municipal water in 2009 are estimated as KRW 1,180.7 per $m^3$ and KRW 1,812.8 per $m^3$, respectively. The economic values of municipal water in 16 cities range from KRW 1,082.7 per $m^3$ to KRW 3,268.6 per $m^3$. Moreover, the economic value of non-residential water is higher than that of residential water in all cities, and the economic value of water is higher than the present price of water. This study is expected to provide policy-makers with useful information to assess a policy and to evaluate the price of water.

Like other artificial architectures, the residence is also hard to be changed after once it has ever been built because its life is approximately estimated up to 20years. Furthermore, it may give big effect to residents as the life Quality. Because of these specificities, it seems to be important to forecast how demand of residential market will be changed and what kind of residential environment should be built in the future. First of all, we should consider about what is a current situation of residential environment in this country before beginning researching resident preferences. In addition, we will also research current and new residential style in other country, which should be concerned in. Finally, this study is researched by domestic male and female residents in their twenties and four ties on purpose to gain information what type of resident style they want and to suggest new ways of future residential environment.

A cross sectional analysis for residential water demand was conducted to help understand and explain the spatial and temporal variations in per capita water use in the rapidly growing city of Riyadh, Saudi Arabia. The analysis was based on data previously collected from May 1983 to June 1984. 195 randomly selected households were distributed to three groups according to house condition, household income level, and social and cultural factors. The generated models using stepwise multiple regression indicated that plot size and number of males, females and children are the most significant independent variables. Although, coefficients of determination achieved for most of the developed models were low (0.2-0.5), the independent variables could still explain a part of the variations fur such a complex social and cultural structure.
