2Barevné Letňany is classified in band B – an energy efficient building.
What is the energy label?
The building’s energy label serves to simply and clearly assess a building in terms of its energy efficiency. It allows buildings to be easily compared in terms of the quality of the envelope construction, and the energy needed to heat the building, and so also the costs inherent in living there. They can be used by current owners and building users, as well as by real estate agencies and prospective buyers or tenants of the building as one of the tools for determining the purchase or rental price. The energy certificate and label is prepared for houses and apartments, as well as for buildings in the service and manufacturing sector.
The building envelope energy label is a graphic expression of the construction and energy properties of the building structure and is similar to the energy label used for electrical appliances. The building envelope energy label, in accordance with revised technical standard ĆSN 73 0541-2:2007, valid from May 2007, replaces the original Building energy label. In comparison to the original standard, the assessment of the construction and energy properties of the building are simplified to evaluate heat loss through the building envelope using an average coefficient of heat transmission.
The energy label classifies buildings within seven bands A–G from very energy efficient (A) to exceptionally inefficient (G). Buildings in bands A–C are considered satisfactory. Band A corresponds to passive houses (ultra-low energy buildings), Band B to low-energy houses. Band C is further divided into C1 (a building satisfying the recommended heat transmission coefficient value) and C2 (a building satisfying the required heat transmission coefficient value).
What are the advantages?
Energy efficient buildings are designed and constructed so that costs for using the building are lower than for buildings constructed according to current applicable standards and regulations.
These costs relate to costs for heating the house, ventilating the house, cooling the house in summer, hot water heating, electricity consumption, water consumption.
