On 25 October 2012, the EU adopted the Directive 2012/27/EU on energy efficiency.
This Directive establishes a common framework of measures for the promotion of energy efficiency within the Union in order to ensure the achievement of the Union’s 2020 20 % headline target on energy efficiency and to pave the way for further energy efficiency improvements beyond that date. It lays down rules designed to remove barriers in the energy market and overcome market failures that impede efficiency in the supply and use of energy, and provides for the establishment of indicative national energy efficiency targets for 2020.
Energy audit can be considered as a means to evaluate the use of energy in a building. Energy auditor uses the technical data, on field measurements and surveillance, questioning of users and past energy consumption to conduct an energy audit. The received data will allow the auditor to perform calculations, based upon which he or she can offer renovation measures in order to reduce energy consumption. The heat losses are calculated for the building envelope and the data compared with the real energy consumption. Energy audit is basically an energy balance for the building, based upon which will be drawn conclusions about energy efficiency measures.
Energy audit may be performed for a variety of reasons:
– Evaluation of energy efficiency of building envelope and heating systems and planning of renovation measures.
– Planning of energy savings measures for a building if renovation of building envelope is planned and necessary.
– Applying a loan from the bank.
– Issuing an energy certificate.
– When improving the technical condition of building and improving energy efficiency at the same time, then the building’s certificate will be better and the value of real estate higher.
Conducting an energy audit:
– The auditor examines the filled questionnaire and technical drawings of the building and begins with calculations.
– Visiting a building that includes surveillance and measurements of the building envelope and heating systems, especially in problem areas. Simple walk-through auditing technique does not require additional measurements, but still, exact figures on temperatures and humidity in the rooms and of the building walls gives more precise information to evaluate the condition.
– The received information is used then to perform the necessary calculations and issuing the report.
– If necessary, the auditor will give additional explanations or clarifications to the building owner.
– When energy audit is conducted during summer period when measurements cannot be done, it is possible to divide the work so that the measurements are done later, during the heating season.
– When thermal surveillance, or thermography is included in the energy audit, then it is recommended to do it before issuing the energy audit. The energy auditor can include the data then in his or her report.
Activities after the energy audit:
– In order to ease the process of applying for a bank loan and organizing the construction work, it is possible to order a project management service. The service includes technical drawings, obtaining building permission, finding construction companies, identifying the best offer, obtaining a bank loan and construction surveillance.
– Energy Savings Bureau is not a one stop shop, but would like to identify itself as a long term partner for its clients in the field of energy efficiency. We are always grateful for feedback about the effect of energy efficiency measurements and would like to help in the future renovation process.
