This paper discusses the effect of various climatic conditions that pertain to passive design measurements and their relationships with building configurations to improve indoor thermal comfort based on the different climate zones in Egypt to support Egypt’s sustainability agenda 2030. We find the most appropriate design settings that can increase the indoor thermal comfort, such as building orientation and shape. These settings can be modeled using DesignBuilder software combined with Egyptian meteorological data. This software is used accompanied by computational fluid dynamics to numerically assess the outcomes of different changes, by simulating indoor climate condition factors such as wind speed and temperature. Natural ventilation simulations were performed for four different shapes to create comprehensive dataset scenarios covering a general range of shapes and orientations. Seven scenarios were optimized to put forward a series of building bioclimatic design approaches for the different characteristic regions. The results indicated that the temperature decreased by about 3.2%, and the air velocity increased within the study domain by 200% in the best and the worst cases, respectively, of the four different shapes. The results of the study gave evidence that the configuration of buildings, direction, and wind speed are very important factors for defining the natural ventilation within these domains to support the green building concept and the sustainable design for a better lifestyle.

Designing solar strategies is a powerful step forward to set up an adequate residential house in terms of energy. Many types of research have simulated the energy needs for residential buildings. Designing an improper installation can contribute to a growth in the overall energy expenditure in ensuring thermal comfort. The use of solar thermal processes in Slovakia is on a rise as compared to recent years. This study models twelve solar water heating systems created on the roof of the household. Solar energy techniques are carried out to comply with the demands of heating and domestic hot water. The analysis deals with the most efficient alternative for the arranged solar systems of the building. Considering these installations and the corresponding overall prices of machinery, the best workable alternative is selected. The potential energy performance of auxiliary heating and the energy output of the solar thermal installation are examined. The required amounts of the different energy contributions are modelled and simulated in specific software for a family house in Kosice, Slovakia. We determine the limits of the design for an apartment and analyse which procedure is used to provide the typical average water expenditure and heating need, covering a multi-criteria analysis considering costs, energy, and life cycle analysis of every installation. This approach can support professionals to decide the best scheme considering these criteria, and this method can be satisfactorily applied. In these conditions, converting a conventional gas boiler into a solar thermal system involves monthly economic savings of around EUR 140–250, with payback periods of 2.5–7 years. The energy requirements are fully covered by the solar thermal schemes and the life cycle assessment resulted in reasonable impacts on the environment.

This article analyzes in detail the impact of wooden houses on the environment using the life cycle assessment (LCA) methodology and at the same time evaluates the indoor environmental quality (IEQ) in these houses. The investigated detached family houses had a wooden structure. The first one had a bearing system made of a wooden frame; other materials were conventional. The second house was built entirely of log wood. Given the high risk of greenhouse gas emissions, the concentration of which in the atmosphere is causing global climate change, the global warming potential (GWP) indicator is crucial. According to results, the family house built entirely of wood and with a biomass boiler significantly reduces CO2 emissions and is therefore considered from the LCA point of view as a more suitable alternative compared to a house with a wooden frame structure. The building materials with the highest share involved in the creation of GWP include concrete structures (38–48%), ceramic roof tiles (33%) and plasterboard (15%). Plasterboard cladding (55%), concrete structures (17–19%), oriented strand board OSB (9–22%), impregnated wooden structures (31–52%) and plastic windows (9%) are the most involved in acidification potential (AP) and eutrophication potential (EP). Plasterboard structures (21%), impregnated wood materials (47.4%), reinforced concrete structures (12%) and mineral wool and roof tiles significantly contribute to the creation of photochemical ozone creation potential (POCP) and ozone depletion potential (ODP). The indoor environmental quality was evaluated through short-term measurements of basic physico-chemical parameters. Since both houses have different characteristics, the aim of this monitoring was to evaluate the actual state of IEQ in selected wooden houses under real conditions. Based on the recorded results, it can be stated that neither presented wooden house, in terms of thermal-humidity microclimate, concentration of CO2 and particulate matter, represents an environment with a negative impact on their occupants. With regards to volatile organic compounds (VOCs), the increased concentrations of xylenes and tetrachlorethylene in the log house were probably caused by the application of impregnation and protective coatings six months before monitoring. In this case, the concentration of tetrachloroethene, which is considered a potential carcinogen, was six times higher than the legislative limit. For VOCs, such as limonene, isobutylene and n-butylacetate, which were found in the wooden frame house, no limits are set. The legislative limits for xylenes and tetrachlorethylene in this house have not been exceeded, and therefore the IEQ cannot yet be considered harmful for health. The presence of all the mentioned VOCs in the interior air of the wooden frame house is more related to the activities of occupants, as this house has been inhabited for several years.

The presented study is focused on the verification of a Building Environmental Assessment System (BEAS). A total of 13 detached family houses representing typical construction sites in Slovakia were chosen for analysis, evaluation and certification by using a BEAS which contains several main fields: A—Site Selection and Project Planning; B—Building Construction; C—Indoor Environment; D—Energy Performance; E—Water Management; and F—Waste Management. The results of this study show that the current construction method for family houses does not respect the criteria of sustainable construction as much as it possibly can. The reason for this is that investment costs for construction are prioritized over environmental and social aspects. Therefore, one house with a score of 1.10 is certified as BEAS BRONZE, ten family houses with scores of 1.56–2.88 are certified as BEAS SILVER and only two family houses with total scores of 3.59 and 3.87, respectively, are certified as BEAS GOLD. The overall results show that the weakest fields of sustainability are Waste management, Energy performance and Building construction. The best-rated fields are Site Selection and Project Planning, Indoor Environment and Water Management. In the future, it is essential to pay attention to those areas where the sustainability criteria have not been reached, as well as to raise project teams’ awareness of sustainability issues and subsequently to transfer them to building practices.

The presented research work is aimed at investigation of the influence of indoor environmental conditions on employees in office buildings. Monitoring of carbon dioxide, temperature, relative humidity and pulse, as well as subjective evaluation, was carried out in three office rooms where air conditioning systems ensured the required amount of fresh air. Investigation showed that in two offices (A and B), the amount of fresh air did not comply with EN 15251:2017. The concentration of CO2 in office A was above 1000 ppm for 72% of the total length of stay. Respondents confirmed fatigue and headaches. In offices A and B, where CO2 concentration was around 1000 ppm, people with a weight of up to 70 kg experienced a significant increase in air temperature as well as odor. Persons with weight higher than 75 kg experienced a slight decrease in air quality. In office C, where CO2 concentration was around 800 ppm, respondents reported a slight decrease in air quality. According to pulse monitoring, it can be stated that in an office where there is an insufficient supply of fresh air, the pulse of a person falls or only slightly rises. A decrease in pulses may indicate the attenuation or stunning of people caused by poor air quality.

This study presents a life cycle assessment (LCA) of ten single family houses located in Eastern Slovakia with the aim to compare them in terms of the materials and technologies used. The main goal is to investigate and emphasize the reduction rate of environmental impact resulting from using green materials and technologies. Environmental impacts are determined by using eToolLCD software. Life cycle impact assessment (LCIA) categories of global warming, ozone depletion, acidification, eutrophication and photochemical ozone creation potential, as well as abiotic depletion potential - elements, abiotic depletion potential - fossil fuels, use of renewable primary energy resources, net use of fresh water, components for reuse and materials for recycling are determined within the cradle-to-grave boundary. Assessed family houses are built as a combination of conventional materials such as aerated concrete blocks, expanded polystyrene (EPS), extruded polystyrene (XPS) and roofing mineral wool and natural materials such as wood, cellulose, clay, straw and extensive vegetation roofs. Multi-criteria decision analysis points out that material optimization of building structures as well as the application of green technologies can ensure a considerable reduction of environmental impacts.

Solar thermal power is nowadays one of the trendiest topics in the construction industry, and it represents a valuable energy source of heating that reduces energy consumption. As solar panels produce heating during the day and consumers demand calefaction during the whole day, we use standby tanks (for domestic hot water) and buffer tanks (for heating) for storage. The latest developments improved the efficiency and useful life while reducing the volume of tanks. So, the presented research work deals with analyzing the solar thermal power in a family house. This work presents a method to create a decision support system to compare solar energy systems in houses from economical, technical, availability, and environmental concerns. The weights of the criteria selected considering the analytical hierarchy process are computed. Parameters required for energy production calculations (location, temperature, etc.) and energy consumption (inhabitants, outdoor temperature, etc.) are summarized. It can be stated that a universal best solar thermal scheme does not exist, as energy consumption depends on the other features and limits as well as energy production, geographical latitude of the location, and so forth. According to results, Case 3 (a gas boiler and a combination tank) is the best alternative for reducing the energy required, CO2 emitted, the best energy efficiency of the installation, and the lowest transmission losses. In other scenarios when the economic criteria are not so relevant, this should be the best case in the prioritization scheme.

We select an old mill building to illustrate the significance of its reconstruction into a residential building underline the architecture of the reconstructed building while retaining the original characters and to analyze its life cycle. Located in Humenné, east of Slovakia, the old mill was denoted as a brownfield. The reconstruction of the old building and the surrounding area is a major cause contributing to decrease in environmental impacts. The environmental effects of the building reconstruction are determined through the standard method of life cycle assessment (LCA) analysis for the system boundary of cradle-to-gate with options. Environmental impact categories, including global warming potential, ozone depletion potential, acidification potential, and some other categories are expressed in the equivalent amounts of emissions and release of carbon dioxide (CO2), trichlorofluoromethane (CFC-11), sulfur dioxide (SO2), phosphate ((PO4)3–), ethylene (C2H4), element antimony (Sb), and energy consumption. Analysis of LCA is performed using a computer software. The observations show that the reconstruction of old buildings is usually preferable to construction of new ones after demolition of the old building. This research work confirms new rational regarding the revitalization of territories in connection with the improvement of quality of life, increase in the value of the given locality and creation of new economic opportunities.

This study performs a life cycle assessment (LCA) of five new family houses in Eastern Slovakia to compare them in terms of the materials and technologies used. The main goal of the analysis is to investigate and highlight the expectable reduction rate of environmental impact resulting from using green materials and technologies. Their environmental impact is determined by using eToolLCD software. The life cycle impact assessment (LCIA) categories of global warming, ozone depletion, acidification, eutrophication and photochemical ozone creation potential are determined within the cradle-to-grave boundary. The examined family houses are built of conventional materials such as aerated concrete blocks, expanded polystyrene (EPS) for thermal insulation and roofing mineral wool, as well as natural materials such as clay, straw, wood, cellulose and vegetation for the roofs. Family houses built of natural materials are characterized by negative emissions of CO2eq in the product phase. Results show that especially the product phase contributes greatly to all environmental impact categories for houses built of conventional materials, such as aerated concrete blocks, mineral wool for thermal insulation, reinforcement concrete and ceramic or concrete tiles.

Sustainable construction and its architecture of buildings seeks to minimize the negative environmental impact of buildings by efficiency in the use of materials, energy, and development space and the ecosystem at large. Sustainable buildings use a conscious approach to energy and ecological conservation in the design of the built environment in cities. This article is devoted to the environmental assessment of three family houses which represent three different material and design solutions. The houses were evaluated through the Slovak building environmental assessment system (BEAS), which has been developed for Slovak conditions at the Faculty of Civil Engineering, TUKE. This study shows that the influence of green design, compared to traditional construction, is important and more beneficial for the practice of designing sustainable buildings. It creates the most comprehensive relationship between the building and its environment and significantly affects building sustainability.

This paper emphasizes the importance of environmental protection regarding the reduction of energy consumption while maintaining living standards. The aim of the research is to observe the effects of mechanical and natural ventilation on energy consumption and building operation as well as indoor environmental quality (IEQ). The results of indoor environmental quality testing show that the mean relative humidity (31%) is in the permissible range (30%-70%); the mean CO2 concentration (1050.5 ppm) is above the recommended value of 1000 ppm according to Pettenkofer; and the mean PM10 concentration (43.5 µg/m3) is under the limit value of 50 µg/m3. A very large positive correlation is found between relative humidity and concentration of CO2 as well as between the concentration of PM5 and the concentration of CO2. The most commonly occurring sick building syndrome (SBS) symptoms are found to be fatigue and the feeling of a heavy head.

Construction and using of buildings for many years produce long-lasting impacts on human health and the environment. Life cycle assessment (LCA) is the rapidly evolving science of clarifying these impacts in terms of their quality, severity, and duration. LCA of three selected new family houses located in Eastern Slovakia is performed with the aim to compare them in terms of built-in materials as well as used technologies. The main goal of the analysis is to investigate and underline the foreseeable reduction rate of environmental impacts resulting from applied green materials and green technologies. LCA impact categories of global warming potential (GWP), ozone depletion potential (ODP), acidification potential (AP), eutrophication potential (EP), and photochemical ozone creation potential (POCP) are selected for this analysis. Investigated family houses are built from conventional materials, such as aerated concrete blocks, reinforced concrete, thermal insulation of silicate mineral slabs, and roofing mineral wool, as well as natural materials, such as clay, straw, wood, cellulose, and vegetation roofs. Product phase contributes greatly to the GWP for houses built of conventional materials. AP, EP, ODP, and POCP impact categories are considerable also in the product phase. Even an operational energy phase contributes a large share of the negative impact on the environment. Adoption of green design and technology in buildings, which can mitigate negative impacts on the environment, has been recognized as a key step towards global sustainable development. The main goal of this article is to make the case that green buildings are important for reducing negative effects on the environment and resources, while simultaneously enhancing positive effects throughout the building life cycle.

Measurements of indoor air quality (IAQ) factors in Macedonian homes were aimed at the determination of indoor air temperature, relative humidity, sound pressure level, particulate matters (PMs) and total volatile organic compounds (TVOC). IAQ monitoring were performed in 25 houses during summer period. Results pointed out that sound pressure level were high in most of the houses with mean values of 66.60 dB (A) - 55.30 dB (A). Limit value of 40 dB (A) was exceeded in 72% of houses. Mean values of indoor air temperature and relative humidity ranged from 21.6°C to 28.6°C and from 35.8% to 60.2%, respectively. Mean concentrations of particulate matter concentrations ranged between 9.75 μg/m3 - 71.73 μg/m3 and 23.63 μg/m3 - 145.10 μg/m3 for PM2.5 and PM10, respectively. Level of PM10 were high in 30% of the monitored houses. 56% of houses achieved higher concentration of PM2.5 than permissible value of 25 μg/m3. Excessive presence of TVOC was recorded in monitored homes with mean values from 260 ppm to 791 ppm. Results show that high exposure by noise, concentrations of TVOC and PMs in indoor air can affect family house users. Therefore, the indoor air quality needs to be investigated and people need to be informed about possible health consequences.

This paper compares the sustainability aspects of three family houses according to the Slovak building environmental assessment system (BEAS). Various categories of family houses were evaluated, including site selection, project planning, building construction, indoor environment, energy performance, and water and waste management. Based on the results, Family Houses 3 and 2 are certified as BEAS SILVER, with scores of 2.46 and 2.01, respectively. Family House 1 is certified as BEAS BRONZE, with an overall score of 1.44. The results show, not only the importance of the site in terms of availability, connectivity to the network and the potential to use renewable energy sources, but also the importance of the design and construction of the building, including the application of environmentally friendly building materials, ensuring the quality of the indoor environment and the energy efficiency of the building. The aims of this study were to highlight the current trend in the design and construction of low-rise residential family houses in Slovakia and to identify gaps in the design and construction of key sustainability aspects through the existing building environmental assessment system. In the future, many low-rise residential family houses will be assessed to modify and validate BEAS.

A significant number of building sustainability assessment methods and tools have been developed over the past two decades. Sustainability assessment of buildings means an evaluation of environmental, social and economic aspects and indicators respecting technical and functional characteristics of buildings to design and construction of sustainable buildings. There are many tools for sustainability assessment of buildings used over the world such as LEED, BREEAM, Green Globes, SBTool, CASBEE, etc. This chapter is aimed at introducing the building environmental assessment system (BEAS) which has been developed at the Technical University of Košice. The Slovak system was developed on the base of existing systems and methods used in many countries. The BEAS includes a number of environmental, social and cultural factors. The indicators were proposed according to the analysis of building performance as well as on the base of experimental experiences. The primary fields are building site and project planning, building construction, indoor environment, energy performance, water management and waste management. Water management in buildings is presented here as a critical issue for achieving the sustainable buildings. Indicators of water management are reduction and regulation of water flow in water systems with the weight of 42.3%, surface water run-off with the weight of 12.2%, drinking water supply with the weight of 22.7% and using filtration of grey water (GW) with the weight of 22.7%.

Paper is focused on the assessment of two alternatives of family house from environmental performance. Environmental impact categories such as Global warming potential (GWP), Acidification potential (AP) and Eutrophication potential (EP) expressed as CO2eq, SO2eq and PO43−eq using the LCA assessment method are presented. Alternative solutions of building materials are also compared from phase shift of thermal oscillation. Results show that natural building materials are characterized by lower environmental impacts expressed as equivalent emissions of CO2 (6%), SO2 (24%) and PO43− (44%). The wood fiber board can store nearly 24 times more heat than the mineral wool. The wood fiber boards have a phase shift of thermal oscillation of 7–13 h, while other insulation materials only about 3–4 h.

This paper aims to assess the environmental impact of family houses designed as a building with green technologies and green materials. These family houses are located in villages of Velky Folkmar and Jedlinka, which are situated in eastern Slovakia. The analysis investigates the role of application of these technologies on impact categories such as: global warming potential (GWP), acidification potential (AP), eutrophication potential (EP), photochemical ozone creation potential (POCP), abiotic depletion potential fossil fuels (ADPF) expressed as CO2eq, SO2eq, PO43−eq, kg ethylene and MJ, respectively within “Cradle to Grave” boundary by using the LCA assessment method. The main contribution of the study is to highlight the significance of green technologies in reduction of environmental impacts. The presented results show that house with built-in green materials and technologies causes significantly lower environmental impacts compared to house where both green technologies and conventional materials are built. The operation phase (B6) is characterized by greater environmental impacts compared to the product and construction phases, as well as deconstruction phase due to the use of green materials and technologies.

Thirty five Slovak households were selected for an investigation of indoor environmental quality. Measuring of indoor air physical and chemical factors and a questionnaire survey was performed during May 2017. The range of permissible operative temperature was not met in 11% of objects. Relative humidity met the legislative requirements in all monitored homes. Concentrations of total volatile organic compounds (TVOCs) were significantly higher in the apartments than in the family houses. The average TVOC levels in the apartments and family houses were 519.7 µg/m3 and 330.2 µg/m3, respectively. Statistical analysis confirmed the effect of indoor air temperature, relative humidity and particulate matter (PM0.5 and PM1) on the levels of TVOCs. Higher TVOC levels were observed also in homes where it is not a common practice to open windows during cleaning activities. Other factors that had a statistically significant effect on concentrations of volatile organic compounds were heating type, attached garage, location of the apartment within residential building (the floor), as well as number of occupants. Higher TVOC concentrations were observed in indoor than outdoor environment, while further analysis showed the significant impact of indoor emission sources on the level of these compounds in buildings. The questionnaire study showed a discrepancy between objective measurement and subjective assessment in the household environment, and pointed to insufficient public awareness about volatile organic compounds (VOCs).

Transition to environmentally friendly technologies provides a comprehensive solution to problem of creating an economic value without destroying the nature. Buildings using green technologies lead to lower operating costs, healthier living and working environment and protect the environment more. The aim of this paper is to assess the environmental impact of two alternatives of family house designed as conventional building and building with green technologies. Evaluated family house are located in village Kokšov Bakša, which is situated 12 km south-east from city of Košice, a metropolis of eastern Slovakia. This analysis investigates the role of applied green technologies in single family houses for impact categories: global warming potential (GWP), acidification potential (AP) and eutrophication potential (EP) expressed as CO2eq, SO2eq and PO43-eq within "Cradle to Grave" boundary by using the LCA assessment method. The main contribution of the study is a proof that green technologies have significant part in the reduction of environmental impacts. Results show that alternative of family house designed as green one contributes to CO2eq, SO2eq and PO43-eq emissions by 81%, 73% and 35% less than alternative of conventional family house, respectively.

The fundamental role of environmental engineering is to protect human population and environment from impacts of human activities and to ensure environmental quality. It relates to achieving the environmental sustainability goals through advanced technologies for pollutants removing from air, water and soil in order to minimize risk in ecosystem and ensuring favourable conditions for life of humans and organisms. Nowadays, a critical analysis of the environment quality and innovative approaches to problem solving in order to achieve sustainability in environmental engineering, are necessary. This article presents an overview of the quality of the environment and progress in environmental engineering in Slovakia and gives information regarding the environmental engineering education at Faculty of Civil Engineering at Technical University in Kosice.
