Existing European energy efficiency standards impose high requirements on yearly consumption of heat energy in buildings and on heat-protective qualities of cladding. One of the options of energy efficient buildings is the “passive house” with low energy consumption. As shown in this article, designs of “passive houses” have not always considered the requirements for preventing condensation in the cladding. Humidity conditions of the cladding of the “passive house” in the city Niš have been analyzed. It was found that for designing a heating system in the outer wall, with a specified outdoor air temperature, formation of condensation exists. To eliminate condensation we conceived vapor barrier layer technology from the inner surface of outer wall. Humidity conditions in the assembly of the vapor barrier layer have been calculated

Today, energy conservation is more and more stressed as great amounts of energy are being consumed for varying applications. This study aimed to evaluate the application of two robust evolutionary algorithms, namely genetic algorithm (GA) and imperialist competition algorithm (ICA) for optimizing the weights and biases of the artificial neural network (ANN) in the estimation of heating load (HL) and cooling load (CL) of the energy-efficient residential buildings. To this end, a proper dataset was provided composed of relative compactness, surface area, wall area, roof area, overall height, orientation, glazing area, glazing area distribution, as the HL and CL influential factors. The optimal structure of each model was achieved through a trial and error process and to evaluate the accuracy of the designed networks, we used three well-known accuracy criterions. As the result of applying GA and ICA, the performance error of ANN decreased respectively by 17.92% and 23.22% for the HL, and 21.13% and 24.53% for CL in the training phase, and 20.84% and 23.74% for HL, and 27.57% and 29.10% for CL in the testing phase. The mentioned results demonstrate the superiority of the ICA-ANN model compared to GA-ANN and ANN.

Energy efficient houses consume less energy while maintaining or improving the comfort conditions of occupants. Energy efficient buildings result in less environmental impact and are economically and environmentally sustainable. Residential buildings account for the majority of electricity consumption in Nigeria. Because of the poor state of energy generation and transmission in Nigeria energy efficiency measures are necessary to reduce the energy required in houses. This would substantially reduce the dependence on the grid electricity supply. Energy efficient buildings have tremendous benefits in social, economic, and environmental terms. In economic terms the production of energy-efficient buildings result in growing market demand with higher quality and innovative buildings, and in social terms it leads to improved urban space and local climate, and liveable buildings. Energy efficient buildings also ensure resource efficiency, and reduction of Green House Gas emissions. Energy efficiency in buildings starts from the design of buildings, and through to construction and operation. The objective of this paper is the examination of energy efficiency in housing in Nigeria and its impact upon socio-economic development in the country. The paper focuses on energy-efficient design strategies, and initiatives to achieve low carbon emission in housing in Nigeria The paper examines the housing situation in Nigeria and the phenomenon of urbanisation which has led to unplanned urban growth, grievous housing poverty, slum formation, and near collapse of urban services and infrastructure particularly electricity supply. It affirms the need to adopt energy efficiency in housing and it examines passive design strategies and low carbon initiatives in housing construction. It takes a critical look at the adoption of sustainability practices in housing. The paper asserts that energy efficiency would enhance the growth of electricity consumption and boost the socio-economic development of the country. The paper concludes that energy efficiency is capable of engendering socio-economic development of the country particularly productivity and income growth.

Radon Concentrations

A comparative analysis of the radon concentrations in modern multi-storey residential buildings of high energy efficiency class and buildings typical for urban areas of the twentieth century was carried out. The study was conducted in Russian cities located in various climatic zones – Ekaterinburg, Krasnodar, St. Petersburg, Salekhard, Chelyabinsk. The radon concentration in samples of buildings was measured using integrated radon radiometers based on nuclear track detectors according to a single method. The surveyed sample included 498 apartments in multi-apartment buildings. Among all the examined building types, the highest average radon concentration is observed in modern energy-efficient houses – 43 Bq/m3. In other types of buildings, the following average radon concentrations were obtained: brick 2–5 floors – 35 Bq/m3; panel 5 floors – 32 Bq/m3; panel 7–12 floors 1970-1990 years of construction – 22 Bq/m3; brick> 5 floors 1970–1980 years of construction – 20 Bq m3; panel, built since 1990 – 24 Bq/m3. The results of the study confirm the assumption that radon concentration in modern multi-storey energy-efficient houses is on average higher than in typical residential buildings of the Soviet period. The increased accumulation of radon in energy-efficient buildings is associated with a decrease in the building envelope permeability and the contribution of fresh air to the general air exchange. Despite the fact that there were no cases of exceeding hygienic standards for the indoor radon concentration in the framework of this study, the higher radon concentration in buildings of increased energy efficiency requires attention from the point of view of implementing the principle of optimization of radiation protection. In the future, extensive construction of energy-efficient buildings may increase the average and collective doses to the urban population in the Russian Federation.

Energy Efficient Buildings

Buildings are significant consumers of energy and producer of greenhouse gases worldwide, and serious efforts have been put into designing energy-efficient buildings. Significant technological advances have been achieved in developed countries; however, advances have rarely been adopted in developing countries like Afghanistan. Such trends emerge from the lack of research in designing energy-efficient buildings to local conditions, practices and materials. This research focused on building energy modelling and simulation to evaluate the energy performance impact of different shading and orientation. The research design follows a case study over an actual seven-storey multi-apartment residential building in the city of Mazar-I-Sharif, Afghanistan, using primary field data and dynamic simulation. Findings demonstrated that neighbouring structures have a positive correlation with a cooling demand. Meanwhile, south is the optimal orientation to face the building's glazed façade, saving up to 7.4% of cooling and 9.7% of heating energy. Moreover, movable shading devices installed on the building's openings in the summer season reduce the building energy load up to 19%, with a total energy cost reduction of AFN. 188,448 ($2447.37 US) annually. The study underlines the vast research scope in customizing building designs to Afghanistan's climatic conditions and other developing countries, thus contributing to buildings’ sustainability.

The relevance of this work lies primarily in the importance of this issue in the construction field. According to statistics, construction projects consume 40% of world energy. Industrial and residential buildings are becoming one of the main sources of thermal emissions of carbon dioxide into the atmosphere. The second argument in favor of relevance is the use of basalt composite reinforcement for brickwork. And the third argument can be the use of CAD to simulate the energy consumption of the building. The practical value of the work is to use the recommendations for the construction and reconstruction of energy efficient buildings located in the Arctic zone. The theoretical value of the developed model and the proposed technology for determining energy efficiency indicators will allow it to be used for further calculations.

Purpose The aim of this study is to propose solutions to ensure comfort conditions for users by taking advantage of the bioclimatic architecture. This could serve as a solution to the energy shortage problem. Design/methodology/approach In this context, 40 bioclimatic buildings located in Greece were analyzed. These bioclimatic buildings were classified according to their climatic zones, functions, parameters pertaining to the physical and built environment, and the passive methods used for heating, cooling and lighting. Findings The high share of residential buildings in the distribution of Greece’s bioclimatic buildings according to climatic zones can be attributed to the large number of users that residential buildings have when compared to other types of buildings. Among the physical environmental parameters, climatic parameters were found to be highly influential. Other parameters had less significant effects, depending on land conditions. Originality value This study revealed the importance of bioclimatic applications in creating energy-efficient buildings. It is also important in terms of setting an example for creating bioclimatic architectural profiles of other countries.
