The most important challenge that companies in our country will face in the coming years will be that of reducing their operating costs through energy savings and successful energy management.
The first step for a successful energy management starts with the energy review and the energy classification of the building facilities in a specific category based on the legislation.
The purpose of the energy review is to identify those points of the building that cause the highest energy consumption. Such points may concern either the installed electromechanical equipment or the building shell.
The energy review begins with the collection of the necessary technical data such as architectural and E / M plans, consumption of electricity, water, gas or LPG and heating oil, car fleet recording (if it contributes significantly) with fuel consumption data, etc. Additionally, experienced engineers conduct reviews of the facilities for identification of points of interest and recording of the equipment that will be checked. In several cases targeted installation of smart meters and sensors is suggested, as well as the utilization of existing building automation systems (if any), which in combination with the Moralius platform, can provide us with useful information about the energy flows of the buildings under consideration. The data collected from the above actions are processed and analyzed in the context of the energy study that follows, calculating the total energy footprint of the facility that contains energy consumption per facility, operation and usage.
At the same time, a techno-economic study is being prepared for the energy upgrade of the facility with proposals regarding the optimization of the operation of the electromechanical systems or their replacement with new technology systems – of lower energy consumption- the structural interventions in the building shell (insulation, frames), the proposal for e-mobiliy sytems with charging stations for electric cars, the installation of building automation and optical fibers and finally a case-by-case proposal for energy cogeneration systems using renewable sources (RES). The study is completed with an estimate of the investment budget as well as its return and amortization, through the expected savings from the reduction of energy consumption.
Thus, in the context of an energy review, a thorough study of the energy performance of buildings and their energy footprint takes place and technical solutions are proposed to address energy costs and savings, which are always accompanied by the complete financial plan.
Along with the energy review, an energy inspection is conducted, that follows specific procedures in accordance with the Legislation and leads to the Energy Performance Certificate. The Energy Performance Certificate (EPC) is a recognized certificate that depicts and ranks the energy performance of a building facility on a scale from A to H, where category A represents the buildings with the highest energy performance (i.e., the lowest possible consumption).
Also, the EPC records the estimated annual energy consumption as well as the annual CO2 emissions and is always accompanied by recommendations for the improvement of energy efficiency. These proposals may refer to either structural interventions in the outer shell of the building (thermal insulation, frames, etc.) or replacement of the electromechanical equipment of the facility or the proposal for installation of renewable energy sources (RES).
The energy inspection and the issuing of an Energy Performance Certificate is mandatory by law for all large companies, is expected to be applied for all companies and is carried out by certified energy inspectors.
