New and renewable energy systems(solar thermal system, photovoltaic system, geothermal system, wind power system) are environmentally friendly technologies and these in South Korea are very important measures to reduce greenhouse-gas(GHG) and to push ahead with Green Growth. The purpose of this paper is to analyze GHG mitigation potential by distribution of solar thermal system in housing sector with bottom-up model called 'Long-range Energy Alternative Planning system'. Business as usual(BAU) was based on energy consumption characteristic with the trend of social-economic prospects and the volume of housing. The total amount of GHG emission of BAU was expected to continuous increase from 66.0 million-ton $CO_{2e}$ in 2007 to 73.1 million-ton $CO_{2e}$ in 2030 because of the increase of energy consumption in housing. The alternative scenario, distribution of solar thermal system in housing sector had GHG mitigation potential 1.54 million-ton $CO_{2e}$ in 2030. The results of this study showed that new and renewable energy systems made a contribution of reducing the use of fossil fuel and the emission of greenhouse-gas in building.

Considering the present development situation of rental apartment since 1982, the supply of homeless housing for low-income dwellers has contributed a amount of quantities, but has been deficient qualities in housing policy. To propose the energy policy for low-income dwellers, this study investigated the energy consumption and the degree of heating satisfaction by heating system through questionaries in permanent rental apartment and 50 year period rental apartment complexes. The results of this study were as follows; The annual energy consumption of heating and hot water supply is 267.2 Mca1/$\textrm{m}^2$ㆍyr in central heating system, is 163.9 Mca1/$\textrm{m}^2$ㆍyr in unit heating system. But from the view of annual energy cost and the degree of heating satisfaction, central heating system were better than unit heating system in rental apartment.

The increase rate of total population slows down and the ratio of the elderly population & single-household in our country is growing rapidly. Korean's housing penetration has already exceeded 100%. So people focus on the qualitative aspects of housing, namely housing welfare than the quantitative supply of housing The purpose of the study proposes the desirable direction for housing welfare policy based on the housing welfare regulations. The data for the analysis was collected through the regulations of 8 cities and 9 provinces. So housing welfare contents like housing welfare business, housing welfare center, etc. were extracted from 4 Housing Welfare Support Regulations, 5 Housing Basic Regulations and 8 Housing Regulations. The results were as follows: To stabilize housing and improve housing, the contents of housing welfare contained in related ordinance are still insufficient. Continue to be effective and housing welfare work, it shall be presented in detail in the regulations with respect to the financing plan. To those who need the housing welfare will have to be built an effective delivery system that can be delivered in a timely manner. For housing welfare for the elderly, housing welfare business information is detailed and broken down, it should be codified.

The National Housing Bond Information Relay System is a representative financial information relay system in which institutions are connected with center system. A centralized structure is expensive to construct and operate center, and there is a problem that all networks are disconnected when a failure occurs in the center system. In this paper, we propose the national housing bond information relay system model based on Blockchain technology that can process information safely and efficiently. The proposed model constructs a Blockchain network so that each institution that processes the national housing bond information can transmit information safely, and each institution manages the same distributed ledge by a smart contract. The proposed model can reduce the cost because it can process complicated national housing bond transaction information without a relay center, and a network usage and disk usage decreased by 1.7% and 8.53%.

Since 1950s, the Korean housing market has continually experienced the chronicle lack of housing stock because of lower housing investment in comparison with a population explosion, prompt urbanization and rapid restructuring of family. The Korean housing market have thus been driven not by the pricing model by housing demand-supply chain but by the Korean housing policies focusing on the increase of housing supply and the living stability of the middle or low-income bracket. After all, repetitive economic vicious circle of housing price and the increase of unsold apartments aggravated the malfunction of the Korean housing market. Meanwhile, the Korean construction firms have exacerbated their profitability. Such terrible situations are mainly triggered by the Korean construction firms that weighed on the short-term profits and quick response of the government policy alterations rather than the prospect of housing market Therefore, this research focusing on the dynamics of housing market identified and classified the demand and supply elements that consist not only of housing system structures but also of the environmental elements that affect the structures. Based on the system thinking and traditional theory of consumer's choice, the interactions of these elements were constructed as a causal loop diagram that explains the mutual influences among housing subsystems with feedback loops. This paper describes and discusses about the causes of the dynamic changes in the Korean housing market. This study would help housing suppliers, including housing developers, construction firms, etc., to form a more comprehensive understanding on the fundamental issues that constitute the Korean housing market and thereby increasing their long term as well as minimizing the risk involved in the housing supply businesses.

This study aims to suggest 'an eco-friendly residential housing design guideline as an elderly housing alternative' by mixing the concept of a 'senior citizen community' housing environment with the concept of an 'eco-friendly' housing environment, based on the directivity of an elderly housing alternative for surviving in a super-aged society and the directivity of a sustainable housing environment for providing against global warming. Basically, this study considered the directivity of 'an eco-friendly residential building as an elderly housing alternative' by analyzing housing environment elements and elements to be considered in an elderly housing environment and setting the directivity of an elderly housing environment, which reflects the change in the design paradigm. In relation to the concept of universal design, for considering the perspective of elderly users, existing elements were compared and major planning elements were applied to the scope of complex planning, communal space and housing unit space. In relation to the concept of eco-friendly design, also, a guideline was re-organized and planning elements were applied to each category by comparing domestic and foreign green building certification systems. Based on domestic and foreign authorized guidelines of universal design and green building certification systems, this study was focused on suggesting an eco-friendly residential housing design guideline as an elderly housing alternative to make users perceive the need for a specific indoor environment design guideline and system.
