Abstract
The topic of energy efficiency is currently under discussion. One of the areas of energy efficiency is the energy efficiency of buildings. The thermo-technical requirements for building envelope structures are gaining increasing importance due to new legislation and technical regulations regarding the reduction of heating and energy demands of buildings over time and because of continuously increasing energy prices. Building construction and the operational costs of buildings are among the largest consumers of material and energy resources and environmental pollutants. Ecological constructions are a response to the current state of the environment. A suitable solution that represents ecological construction, operation and comfortable living is the construction of low-energy and passive houses based on wood. Wood-based buildings have many benefits that are particularly timely in the context of sustainability today. The aim of this paper is to introduce selected aspects of wood-based buildings in the context of energy efficiency and thus to reduce the adverse effects of construction on the surrounding environment.
Highlights
The European Union is paying more attention to the issue of overall energy savings
In terms of operating costs, heating costs were analysed, which in general account for 58% - 67% of total operating costs on average [14, 15]
All the operating costs were sought from the respondents, most respondents reported only the heating costs
Summary
The European Union is paying more attention to the issue of overall energy savings. The reduction of energy consumption and the use of renewable energy [2] in the building sector are important measures needed to reduce energy dependency and greenhouse gas emissions. This creates the preconditions for achieving the set of energy efficiency targets. 2010/31 / EU on the energy performance of buildings in which new requirements for the construction of new buildings are stipulated to ensure that all new buildings constructed after 2020 are nearly zero-energy buildings. For new buildings which are owned and operated by public authorities, there has been a requirement for buildings to have almost zero energy consumption since 2018 [3]
