Public building in Prague gets bespoke ventilation and heat recovery

• Well-ventilated indoor environment considered worth the premium for an office refit
• Energy consumption reduced by ~600 GJ per year
• Annual energy cost savings estimated at ~€ 9 000

An administrative building in Prague, the Czech Republic was fitted with a bespoke ventilation and heat-recovery system implemented during a recent refurbishment. The aim was to optimise air circulation  in the building and minimise heat losses during ventilation.

Measuring and control systems (MCS) are used to automatically control both manufacturing and non-manufacturing processes, including monitoring, visualisation and evaluation.

Ageing induction motor got an overdue upgrade

• Upgrading VSH’s 45-year-old electric induction motors yielded results
• Reduced energy consumption of ~388 GJ, saving € 34 567 yearly
• Investment in motor efficiency controllers will pay for itself within 3 years   

The Czech company VSH produces and sells building materials, including a cement plant which was built in 1973.

Why not be more ambitious? 

• New pump with frequency inverter delivered energy cost savings of nealry € 20 000 annually
• Return on investment was 2.1 years

The company Paramo, Czech Republic, which produces and sells fuels, motor and process oils, asphalt and coatings for the construction industry, implemented an ambitious energy-saving project to replace its cooling-circuit pump.

Traditional accounting systems are not routinely designed to provide companies with information about total costs related to the use of resources and generation of waste and emissions. When a company is able to calculate and allocate costs on so-called non-product outputs, it can better monitor the real efficiency of materials and energy use that leads to better management of resources and financial savings.

The right balance makes a difference

• Top 20 analysis highlights where immediate energy and materials savings can be made 
• Optimising the software on a heat pump saves about 20 000 kWh of electricity per year

HAASE Gesellschaft m.b.H. is a producer of high-temperature, low-sag energy cables and rope and lifting systems from Graz, Austria. The company carried out a Top 20 input-output analysis, which revealed potential areas of improvement in processes, products and the whole product life cycle.

Positive experience inspires continued effort

Look closely and all kinds of savings can be found

Beware the unknown costs!

• Textile business discovers inefficiencies in production and important cost-management gaps
• TOP 20 follow-up helps the company reduce energy consumption by over 5 %

Oritex is a small dyeing and knitting house based in Lodz, Central Poland. As part of the company's broader mission to lower its impact on the environment and improve production, its management requested a TOP 20 input-output analysis.

Open the door to resource efficiency!

• Analysis spots outdated machinery and poor energy- and water-management practices
• Measures help to cut the company's energy consumption by over 5 %
