The LEA - as a company accredited by the province of Styria - issues energy performance certificates for residential and non-residential buildings and carries out the data collection in the case of missing building data (e.g. in the case of missing planning documents, the natural dimension survey, building physics survey, etc.). The energy certificate and the associated expert advice from a competent energy consultant are used for both new construction and refurbishment projects. In addition, the energy certificate is the prerequisite for access to federal and state funding opportunities. With the energy certificate for your building, you benefit in the form of: - savings in operating costs during operation due to energy optimisation recommendations - securing the market value of your property - subsidies through presentation of the energy certificate
