Ecodesign and Energy Labelling
The energy efficiency improvement target of the European climate and energy package for 2030 strongly influences the heating, ventilation and air conditioning (HVAC) market.
Indeed buildings are the largest consumers of energy today and, of that consumption, HVAC systems account for considerably more than any other equipment. Providing its customers with energy efficient solutions is therefore now a key sustainable development opportunity for the HVAC industry.
Ecodesign is an approach to product design that encourages manufacturers to consider the environmental impact of the product over its entire lifecycle. In the European Union, the Ecodesign Directive 2009/125/EC establishes a framework for the setting of mandatory energy efficiency requirements for all energy-related products (ERPs).

Ecodesign and Energy Labelling for heat pumps
Since September 26, 2015, heat pumps are the first HVAC commercial products to be covered by the Ecodesign (heat pumps up to 400 kW ) and Energy Labelling (heat pumps up to 70 kW) regulations. Products placed on the market before this date will not be affected. Conformity is mandatory for a product to obtain the CE marking.
New energy efficiency metric: SCOP
The Seasonal Coefficient of Performance (SCOP) is a new European parameter to evaluate the energy efficiency of heat pumps. It replaces the Coefficient of Performance (COP), which measured the ratio of power consumed to power produced in the heating mode on a single operating point. Unlike its predecessor, the SCOP is representative of operation during the heating season as it includes seasonal variations by defining several realistic measurement points. Together, these contribute to classification in the correct energy efficiency class. Carrier heat pumps are all in the classes A to A ++.
SCOP versus COP efficiency
1 temperature condition: 7°C
AUXILIARY MODES (KWH)
No auxiliary power modes taken into consideration
Several rating temperatures: -10°C to 16°C (average climate)
Partial load + Full load
Includes consumption auxiliary modes: - Standby mode - Off mode - Thermostat off…
Number of hours occuring at each air temperature (bin hours)
ANNUAL HEATING DEMAND
SCOP is the ratio between annual heating demand and annual energy input over an entire heating season.
