Taking a typical rural building as an example, the paper compares various factors that affect the heat load of the building, studies related literature and the living habits of rural residents, and suggests that the calculated temperature of the heating room in rural residential buildings in cold areas in winter is 14~17?C. Analyze and compare the initial investment and the investment pay-back period after the thermal insulation measures are adopted for each envelope structure. With the dual goals of energy conservation and economy, it is recommended that rural households with different economic conditions adopt different thermal insulation measures to provide clean heating in rural areas in the cold north. Provide strong technical guidance for energy conservation and emission reduction.

The paper analyzes research, technologies, and equipment related to wastewater heat utilization systems. The main factors influencing the development of the industry and the implementation of such systems are given. Such factors include: social, political, economic, technological, legal and environmental. The classification of technologies and equipment for wastewater heat utilization according to the place of heat extraction is given. Namely, low potential wastewater heat can be collected at the treatment plants, in sewer collectors leading to treatment plants and directly in houses. The paper describes the available research in the scientific literature on these three categories The global scientific community is working to create efficient wastewater heat recovery systems. The environmental situation requires greater use of wastewater recovery systems. An important issue is to increase awareness and education of the population, as this approach will increase the degree of implementation of wastewater heat utilization systems in residential buildings.

Country Specific

Energy labeling of buildings is accepted and used in all European countries. Depending on the yearly specific primary energy consumption the energy quality of a building is expressed using a country specific method. Consequently primary energy is the basis of building energy class. Primary energy is obtained using different country specific transformation factors for gas, electricity, wood, biomass etc. However different quantities of warm water and steam can have the same energy content. Calculating the exergy content of used energy a better classification of buildings can be achieved. This paper presents a method to analyze residential buildings from exergy point of view. It was found a transformation factor between energy and exergy: 0.075.

Lightweight frame structures become increasingly popular in housing. They are used in single-, as well as multifamily, residential buildings. Such a tendency is in the line with sustainable development and the need for energy conservation. Lightweight frame partitions provide a certain comfort of life and remain environmentally friendly. However, they are tricky in terms of acoustics. Different factors and technical details influence their sound insulation. The paper presents the analysis of the acoustical effects resulting from different layers used on lightweight frame floors. Airborne, as well as impact sound insulation, have been considered, based on the results of laboratory measurements according to ISO 10140 standard.

The article considers the classification of both compact built-up development areas of cities and populated localities, and the objects included into the scope of these territories: buildings, urban structures, utilities, etc. At the 1st stage, we suggest to form clusters out of the urban environment areas, and also property items located on the territories considered with the following uniform characteristics used: depreciation, obsolescence, level of technical comfort of territories and objects determined as per the special methodological procedure. At the 2nd stage, we suggest to group the separate construction objects located at the territories considered: residential buildings, utilities, etc. into clusters based on space-planning, engineering, structural and other one-type characteristics. The set of territorial clusters, which are formed based on a number of uniform characteristics, will make it possible to assure sustainable planning of retrofitting and renovation of urban environment areas by using standard organizational and management solutions, construction machines, repair and reconstruction methods for uniform clusters.

Hot And Humid Climate

The use of Prismatic Skylights and its effects as a passive Energy Conservation Strategy in “Residential” and “Big Box Commercial Buildings” in hot and humid climate has been evaluated throughout this project. The potential benefits of using skylights reside in the fact that it reduces electrical lighting necessities but at the same time it contributes to an upsurge of the Cooling Loads of the conditioned space. Acknowledging the impact of skylights is fundamental to elaborate an optimized design of a building’s energy efficient mechanical system. To reach a sound conclusion, the evaluated buildings were modeled and their performance was simulated using the Department of Energy Simulation Program “Energy Plus”. To be able to compare the Energy Conservation Measure case (Using Skylights) with the Base Line (No Skylights), a photometric sensor was modeled to ensure that both cases sourced the same amount of light visible in the electromagnetic spectrum. Considering the Heating, Cooling and lighting energy consumption as variables, the variance between the ECM and the Base line for the residential case was 5% more energy consumption with skylights. For the Big Box Commercial Building there was a 5% deduction in energy consumption in the ECM case using 5% roof area covered with skylights. The results obtained from this investigation reveal a very promising effect in the implementation of skylights in “Big Box Commercial Buildings”, but not so optimistic in the case of “Residential Buildings” for hot and humid climate as shown by the simulation and monitoring data from the experimental case.
