Renewal of the technical centre - more efficiency and more comfort for the operations building.

The goal:

• Largely dispenses with fossil fuels with a low-temperature system by employing air source heat pumps
• Renewal of the air compressors 
• Heat recovery from the compressors 
• Utilisation of the waste heat for heating and hot water
• More comfort thanks to the supply of fresh air in the production halls

Our solution:

• New heating system with gas condensing boilers to cover peak loads
• Supply and exhaust air systems with heat recovery in the production halls
• Use of waste heat from the air compressors
• Integrated refrigerant dryer in the compressors
• Generation of heat and cold through the use of several heat pumps
• The installation meets the eligibility criteria of Kommunalkredit Public Consulting (KPC). KPC will subsidise up to 30% of the investment costs of energy efficiency measures in production plants
• Storage of waste heat in the heating buffer, which is also used for the air source heat pump

The data:

• The heating load is reduced by half
• Replacing the compressors amortises within 9.08 years - followed by 64% savings in compressor operating costs
• The heating system amortises within 5.34 years - followed by 79% savings in operating costs for heating
• CO₂savings of 36 tonnes/year as a result of compressor replacement
• CO₂savings of 892 tonnes/year as a result of the new heating
• CO₂overall savings of 928 tonnes/year
