Energy efficiency

During the energy crises and since the first oil crisis in 1973, and then following crises of 1979 and of 2008, energy efficiency has become a major issue of the construction sector, industry, and to a lesser extent, of infrastructure.
As for the construction sector, BETEN carries out diagnostics and audits, provides innovative solutions, as for building envelope, so for internal flow management, air conditioning, heating / ventilation, and local renewable energy generation.
Under the influence of the permanent increase in the energy price, control of energy consumption under the project is a major challenge for the coming years. Often there is also a large potential for possible reduction of consumption in both industrial and service sectors (which can come up from 20% to 40%), driven by production costs reduction as for the individual housing, so for public housing sector, or in the field of electricity production and distribution.
As for the energy efficiency, BETEN develops its know-how internationally and mainly in the CIS counties, in particular in Ukraine, Kazakhstan and Moldova. Among our activities there are energy audits, performance analysis, development of plans of action for improving energy efficiency, as well as awareness campaign elaboration and training for prescribers and consumers.
Our services cover all kinds of electricity consumption (lighting, ventilation, office equipment, processing lines, electric motors, compressed air, air conditioning systems and industrial refrigeration systems), but also gas and fossil energy consumption (boiler heat production and processing lines). BETEN is also active in the field of biomass and the hot water production by solar water-heater.
The audit establishes an overview of the situation of an enterprise or a building and assesses the prospects for its consumption reduction and the possible level of its energy efficiency.
It is based on a collection of technical data (consumption, output, etc.) and economic data (energy consumption, operating costs, value added, etc.). These data are used to produce general indicators under the form of technical or techno-economic ratios, such as kWh /m²/year for buildings, kWh/unit of production or kWh/turnover for companies, but also more targeted technical ratios for such processes as kWh/m3 for example for the production of compressed air or energy efficiency for boilers.
These indicators are compared to the reference or specific benchmarks which are adapted to every application: standardized scales of buildings’ thermal performances, specific technical references for industrial processes.
In accordance to the results of the audit a report is delivered to the Client, so that he can choose its investment policy being aware of the situation thereby.
Energy study is a further more detailed analysis which includes a feasability study, followed by corrective actions to achieve significant savings.
It comprises detailed data collection, complemented by a measurement campaign, and in-depth critical analysis that evaluates the technical aspects of the operation and energy efficiency of equipment in terms of regulatory requirements that are applied.
After finishing all these studies we propose an action plan and a program, including project planning and its budget.
BETEN is also involved in supporting its clients for:
  • Entertainment programs and awareness campaign for personal,
  • General design with adaptation of faisability studies to ukrainian standards (stage P) with customer support aiming to obtain all the necessary authorization until the issue of Notice of Commencement.
