Abstract
According to the European Green Deal, climate change and environmental degradation pose an existential threat to Europe and the world. Therefore, Europe needs a new “green” strategy to transform the EU into a modern and competitive, resource-intensive economy, with zero net greenhouse gas emissions by 2050. As a result, economic growth will be decoupled from resource use. The ever-increasing requirements for the urban environment to be carbon neutral lead to the rising needs for buildings from three dimensions of sustainability. It is well known that the construction and operation of buildings are the primary consumers of energy and material resources and significant polluters of the environment during all stages of their life cycle. This paper deals with analysing environmental impacts and life cycle cost of two family houses located in Kosice, eastern Slovakia. The total greenhouse gas emissions for family house 1 generates 45.89% more CO2 emissions during its life cycle. Discounted life cycle cost of a family house 1 is 74.33% higher and nominal even 77.22% higher than the nominal life cycle cost of a family house 2.
