This research assessed the economic impact and construction costs of buildings with solar chimneys in Thailand, called bioclimatic houses. A solar chimney uses a combination of air gaps between walls ...and roof, and effective ventilation to lower the indoor temperature and reduce the need for air conditioning. The study looked at small, medium, and large size houses and studied construction techniques, the materials used, and the time needed to build a residential structure. It also polled owners of bioclimatic houses about their satisfaction. The techniques employed in building bioclimatic houses take slightly longer and cost slightly more than those used in standard construction. However, the study found that bioclimatic houses use approximately 10-20% less electricity for air conditioning require less maintenance and have a payback period of 6-13 years, depending on the size. The lifespan of insulation material used in standard houses is about 20-25 years, while the lifespan of a solar chimney is about 40-50 years. The solar chimney concept can also be applied to standard houses with minimal renovation. The study found that this type of house was suitable for use in Thailand, and with increased consumer awareness, had a high probability for adoption.

SII issues a subsidy for a person realizing ZEH and inspects an energy-saving effect to be provided by the introduction and performs activity to plan the further energy saving spread by announcing ...the result. In "net zero energy house support project investigation presentation 2014", SII announced the analysis that compared the results data with the plan level of the ZEH owner after the residence for one year. I describe ZEH and ZEH support project mainly on our country's first ZEH summary which SII announced.
The article covers development of energy performance and energy saving in Russia, relevant issues of development of energy-saving construction, as well as pilot projects of construction of ...energy-saving (“smart”) houses implemented with participation of State Corporation — Housing and Utility Reform Foundation. A separate emphasis is made on perspectives of development of “green” (environmentally friendly) construction, the main task of which is reduction of total influence of constriction site on environment and human health, what is reached on account of efficient consumption of energy, water and other resources, as well as reduction of waste and emissions.
This paper studies on the design principles of energy-saving house in Xi'an city, and aims to put forward measures for constructing ecological residential communities in this city. There are four ...parts of this paper. The first part points out the necessity of such research based on the climatic characters of Xi'an and the problems in housing development projects that overlook energy conservation; the second part proposes several design principles for energy-saving house, including using natural daylight, optimizing natural ventilation, arranging planting, water and pavement reasonably, using regenerative energy, improving quality of exterior construction, etc.; the third part uses a completed housing project in Xi'an to analyze the advantages of applying the above principles for energy conservation; and the last part draws a conclusion about design principles for energy-saving house in Xi'an.
The main purpose of this research is to assess the impact of four types of energy-saving houses on environment in terms of CO2 emission. In the tropical climate, House 1 is designed as an integration ...of modified Trombe wall and roof solar collector using concrete block and concrete tiles, House 2 is normally built by concrete blocks and concrete tiles, House 3 is built as usually found in Thailand by red clay bricks and concrete tiles, and House 4 is built with lightweight autoclave concrete blocks and well-insulated roof. All house model dimensions are 1.3 × 1.3 × 2.5 m3. The collection of inventory data is associated with the construction stage, average household electricity consumption, maintenance in the using stage, and energy usage in the demolition stage. Electricity for residential consumption is based on the temperature collected through the experimental data in each house in 1 year. Subsequently, the environmental performance is assessed by Impact 2002+ life cycle impact assessment methods. The result shows that House1 has the highest score in terms of energy and environmental performance which can reduce the amount of CO2 emission contributing to global warming even from the first year of operation.
