Energy concepts, audits and feasibility studies
The processing of energy audits, concepts and feasibility studies is one of our services provided for many years. In this area, we have high-quality experts and long-term and extensive experience. Our energy audits, concepts and feasibility studies are always processed with the utmost regard to the benefits for the customer and, in particular, to the technical and economic viability of their outputs.
Energy audits are performed in compliance with Act No. 406/2000 Coll., and must be carried out by all entities with energy consumption higher than 35 000 GJ and for equipment in public ownership with consumption higher than 1 500 GJ/year.
SEVEn has been carrying out energy audits and concepts since 1991, both for industrial corporations as well as for other operators of buildings and technological equipment. SEVEn workers have the qualifications required for working on energy audits in accordance with the applicable legislation.
Apart from developing the methodological approaches and technical aspects of energy audits, SEVEn primarily monitors the strategic aspects, i.e. their long-term benefit for various companies’ economic results and the increase in their competitiveness.
SEVEn usually extends the legally required energy audits to include above-standard items, in particular risk analysis, pre-project preparation and a proposal on the method of financing.
SEVEn has a good overview of the commercial and subsidised financial resources available, thus ensuring that it can prepare a complete service for qualified decisions in the field of investment advice.
SEVEn offers evaluation of the options for financing projects by a third party, i.e. a contract for energy services such as EPC/EC, including the preparation of selection procedures for these services.
Energy concept for the Prague Zoo
The essence of the feasibility study was to verify the technical and economic prerequisites for constructing the educational Energy Centre, which will demonstrate practical ways of using alternative energy sources. After examining the different options, the best solution was found to be combining the operation of a biogas plant with composting facilities and a biomass boiler house. The solution proposes that the biogas station uses the energy of organic materials of non-wood origin. Co-generation would transform valuable biogas energy into electricity and heat, which would be later used for the zoo’s needs. Wood trimmings and chips would then be burnt in a special boiler used for heat production. The proposed thermal output could cover the heat consumption of the new pavilions, which are under construction in the northern part of the zoo. In addition, the aim is to make the Energy Centre complex accessible to the public, and to show the zoo’s visitors how materials of organic origin in the zoo can be used in an environmentally friendly way.
Study of the savings in the service buildings of the National Theatre in Prague
Following the example of the main theatre stages, the National Theatre’s management has decided to continue in reducing operating costs for energy in the other buildings it administers for support activities, those being the service facility of the former St. Ann’s Monastery in the Old Town and a group of buildings in Viničná ul. SEVEn compiled studies of potential savings for both locations in electricity, gas, heat and water usage, which were used as a basis for energy-saving projects carried out by the EPC method (i.e., an external supplier with a guaranteed result). The results of the analyses confirmed the significant economic potential of energy savings.
Energy audit of Písek Hospital
SEVEn compiled an energy audit for Písek Hospital, which became part of the application for support from the Operational Programme Environment for thermally insulating the hospital buildings. The potential savings of the recommended solution – thermal insulation of 7 hospital buildings – form about a tenth of the energy consumption in the hospital premises.
