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.
Ecodesign
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).
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 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 Calculation
SCOP is the ratio between annual heating demand and annual
energy input over an entire heating season.
