The article deals with the issue of environmental certification of buildings, which was emerged in the 1990s to make it easier to compare buildings and their impact on the environment. The environmental certification of buildings mainly assesses how the building affects its surroundings and the quality of the indoor environment. Environmental certification currently represents a trend that has extended from office buildings to commercial, logistics or hotel facilities. However, a large number of certification tools is currently used all over the world and almost every country uses a different evaluation methodology. Moreover, in some countries, more certification methodologies that compete with each other are used, as is the case in the Czech Republic. This results in a confusing situation in the field of environmental certification which prevents more extensive development of environmentally friendly construction, where the energy efficiency of buildings and their environmental impacts constitute up to a third of the total project evaluation in the preparatory phase. For this reason, the research described in the article compares six environmental certification systems, namely BREEAM (Building Research Establishment Environmental Assessment Method), LEED (Leadership in Energy and Environmental Design), SBToolCZ (Sustainable Building Tool CZ), WELL (Well Building Standard), DGNB (German Sustainable Building Council) and HQE (High Environmental Quality). At the same time, the environmental certification impact on the amount of selected operating costs used for calculating the operating costs per m2 of useful floor area has been assessed on a model example and then compared. The research assessed the costs of electricity consumption, water and sewage and heating. [ABSTRACT FROM AUTHOR] |
