Energy Efficient Building

Energy efficiency of buildings, of course, is now a major issue in the construction industry. It is being widely examined both among construction professionals and amateurs. There is no doubt that energy efficiency as a key factor in ensuring environmental sustainability will become the main driving force of the construction in the future. Buildings have to become more energy-efficient. This opinion is supported by the existing energy-use balance in Europe, indicating that the housing sector spends almost half of total energy consumption and building sector forms more than a third of total CO2 emissions (Bradley 2010). While discussing the subject of building energy efficiency, mostly different technical characteristics of buildings and engineering solutions are talked over. However, it has been relatively little examined how energy-efficient design affects the building’s architecturally-aesthetic side, styles of expression and trends in the architect’s profession. We learn that the essence for an energy-efficient building lies in smart modesty (Bokalders, Block 2010) and the rational utilization of materials (aim high – go low). And still – can energy efficient building be expressive, extravagant, and perhaps – even ambitious? There are many ideas implemented in projects which show that energy efficiency is not an obstacle to large scale architectural ideas. However, in order to combine architectural and artistic ambitions with the principles of sustainability, architects should search for an entirely new approach to architectural expression based on a detailed assessment of solutions applied from environmental point of view. It requires a complex understanding of building shape, applied technologies, energetic benefits and cost parameters. This article identifies the realised and experimental projects of the world and presents an analysis of classification of buildings according to typology. This publication gives general impression of the amplitude and topicality of the study issue, as well as the diversity applied to the architectural techniques. The article concludes that even creating a building’s shape in a smart way makes it possible to use substantial part of the renewable energy offered by nature.

The Impact

Energy demand reduction in buildings is an important measure to achieve climate change mitigation. It is essential to minimize heat losses in designing phase in accordance of building energy efficiency. For building energy efficiency in a mild climate zone, a large part of the heating demand is caused by transmission losses through the building envelope. Building envelopes with high thermal resistance are typical for low-energy buildings in general. In this sense thermal bridges impact increases by using of greater thickness of thermal insulation. This paper is focused on thermal bridges minimizing through typical system details in buildings. The impact of thermal bridges was studied by comparative calculations for a case study of building with different amounts of thermal insulation. The calculated results represent a percentage distribution of heat loss through typical building components in correlation of various thicknesses of their thermal insulations.

Energy Efficient Building

In the present study a GUI tool for the prediction of building energy performance based on a three-layered BP neural network and MATLAB was developed. The inputs for this tool are the 18 building envelope parameters. The outputs are building heating, cooling and total energy consumptions and the energy saving rate. Compared with the complicated mathematical equations, this tool provides a very easy and effective method for students to learn the effects of building envelope performance parameters on the building energy performance. Thus, this tool can be used in building physics and building energy efficiency courses for the design of energy efficient building.

Energy efficiency in the building sector is a priority of the EU Commission to achieve carbon neutrality by 2050. Renovation of the existing buildings, which are currently responsible for approximately 40% of EU energy consumption and 36% of the greenhouse gas emissions can lead to significant energy savings. This paper presents the EEnvest calculation method for evaluating the financial impacts of technical risks related to energy-efficient renovation of commercial office buildings. The evaluation method aims to increase investors’ confidence and boost investments in the renovation of the existing building. Through a series of Key Performance Indicators (KPI), the technical and financial risks impact is evaluated. The results are strictly connected to building features, climatic conditions, solution sets and mitigation measures specific to the building energy efficiency project.
