Comparison of new Slovene regulation "Thermal Protection and Efficient Use of Energy in Buildings" with EnEV

In the framework of harmonisation of the Slovene legislation with the European, in 1995 the Ministry of Environment and Physical Planning of the Republic of Slovenia began with the preparation of new Slovene standards and regulations. In the first phase adopting of a whole range of standards was planned. In the second phase, which is presently running, the preparation and adopting of regulations has to be completed. In the field of building physics the work on regulations for day-lighting in living and working environment, energy use in buildings, ventilation, waterproofing and glass is underway. This paper presents the proposal for a new Slovene regulation on "Thermal Protection and Efficient Use of Energy in Buildings". The Slovene regulation is in the preparative phase, thus certain points can still be discussed and changes can be made. The presentation is designed as a case study. The annual energy use is calculated according to two regulations: the new Slovene regulation proposal and the German "Energieeinsparung-Verordnung". The comparison is carried out on a case of a simple residential building of 196 m2. The building has a rectangular floor-plan with 8 m and 12 m sides. It is 6 m high (ground-floor and 1st floor). On the basis of both calculations comments on similarities and differences are presented.
