Development of nearly zero energy buildings and application of cost optimum

Abstract

The article deals with the topic of nearly Zero Energy Buildings (nZEB) and cost-optimal level. The definition of nZEB comes from the European and national legislation. A model was established to compare the costs of construction and operation of nZEB. The share of the new low-energy construction market is approximately 4% per annum in the Czech Republic.
