Abstract
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.
Highlights
Reducing the impact of buildings on the natural environment and people is a key factor when planning the sustainable zones and towns in the world
The findings reveal fourteen themes that are considered for assessment: management, sustainable site, transport, indoor environmental quality (IEQ), water, waste, material, energy, pollution, innovation, economy, society, culture and the quality of services
The points obtained are higher for the case study located in Orvieto (LEED 43, ITACA 61.94) than for the case study located in Foligno (LEED 41, ITACA 57.91), which shows that both methods assign scores in similar proportions
Summary
Reducing the impact of buildings on the natural environment and people is a key factor when planning the sustainable zones and towns in the world. An integrated LCAeLEED model, presented in study [11], incorporates LCA into LEED and assigns corresponding LEED scores to achieve a high level of sustainability assessment for the structure and envelope systems of Canadian school buildings. In this model, the selection of the most sustainable structure and envelope type for school buildings is conducted through the evaluation of three categories of the LEED rating system: energy and atmosphere, materials and resources, and LCA. Plant materials largely conserve carbon within their mass and contribute to the elimination of global warming
