Industrial areas ZLKL s.r.o.
The Client
Our client for this project was engineering company ZLKL s.r.o., which in 2012 ranked 3rd place and in 2013 1st place position in the Company of the Olomouc region contest. It also won award Responsible Company of the Olomouc Region in 2013. Use the services of energy consulting was an inevitable step in the quest for the most efficient operation of an industrial enterprise.
The company operates 4 production facilities of various sizes and fitted with different production technologies (metal cutting, administration, development offices, paint, quality office - 3D measurement, ...). All of these areas, our experienced technicians mapped in detail and made them an energy audit with emphasis on measures with a payback within 5 years.
Assignments and Objectives
- Analysis of HVAC systems and manufacturing technologies
- Analysis of energy consumption in relation to the production of individual areas
- Energy management of the company - analysis of current situation and proposals for improvement
- Energy savings measurements proposals
Results
All of the heating systems of the individual objects (or their parts) have been shown to be very inefficient from the point of view of regulation. There were designed adjustments to ensure the possibility of effective regulation.
Using the matrix of energy management based on ISO 50001 methodology the current status of energy management of the company from the perspective of company management as wall as from the perspective of personnel responsible for company production. The result was the evaluation of energy management across the whole structure of company. Further, there were recommended specific steps to increase the level of energy management. One of these recommendations was the use of our software for energy management Enectiva.
Data on energy consumptions were analysed in comparison with production performance data. The results showed abnormalities that demonstrated the importance of energy management and the potential for further savings in its introduction and thorough compliance.
Our output also included a set of proposals for savings measures across all consumed energy including the recommendation to process tender for electricity supplier due to the favorable evolution of stock prices with the relatively high price of current supplier. The amount of savings was 470 000 CZK/year.
As the largest share of energy consumption in investigated areas has electricity, its delivery and quality was paid high attention. Therefore another measure suggestion was installing the electricity load controllers, reducers and active filters. The installation of these devices can reduce the annual cost of electricity by 400 000 CZK.
Summary of suggested measures and savings
| Measure category | Number of measures | Total yearly savings |
| Low-cost (0 - 100 000 CZK) | 3 | 500 115 CZK |
| Medium-cost (100 000 - 1 000 000 CZK) | 4 | 135 805 CZK |
| High-cost (1 000 000 - 10 000 000 CZK) | 1 | 308 000 CZK |
