emergency calls for solutions that reduce
greenhouse gas emissions and support decarbonisation.
O… en, the spotlight is aimed at
renewable energy as the solution, but in fact,
we can achieve 44 per cent of the required
global reductions by capturing the potential of
energy e iciency according to World Economic
Forum.
Investing in existing technologies enables us to
become carbon-neutral significantly more coste
ectively and at a higher pace than if we solely
focus on expanding renewable energy.
Imagine if we could achieve the majority of the
carbon-emission reduction targets with solutions
already at hand. The socio-economic savings
by investing in energy e iciency is a route that
deserves more attention. If we invest in already
known technologies, we can introduce renewables
at a higher pace and in a more cost-e icient way in
our endeavours for carbon neutrality because when
the use of renewables increases, it reduces the
pressure on the growth of clean energy. All fingers
point at scaling up sustainability and developing
green cities, sustainable products and product
life cycle assessments and both renewables and
improved energy-e iciency is a prerequisite
for this development.
Energy-guzzling old equipment
Urban areas account for two-thirds of global energy
demand and 70% of carbon dioxide emissions. One
of the obvious ways to bring down urban energy
consumption levels is to invest in energy-e icient
heating and cooling in buildings and to electrify
transport. If all urban areas and cities in Europe,
China and the US invested in energy-e icient
buildings, they would contribute 20% to the 1.5°C
target of the Paris Agreement.
Ine icient centrifugal and axial fans with
non-optimised aerodynamic design are some
of the worst energy-guzzlers. But new solutions
are available. NOVENCO® ZerAx® axial fans have
e iciency levels of 92%, where older fans hit
somewhere between 50 to 80%. Cities need a vast
number of fans to provide fresh and clean air in
tunnels and parking basements, as fire protection
fans and for heating and cooling in buildings.
Replacing old existing fans with new high-e iciency
alternatives, with favourable ROI periods, is a
practical and cost-e ective solution.
The NOVENCO EC+ solution combines our ZerAx
fans, PM motors and Danfoss VLT variable speed
drives, enabling intelligent building ventilation with
the highest possible levels of e iciency and reduced
energy, emission, heat gain and sound levels.
Abundance of good-will but lack of action
To bring about this change, we have to embed
the good intentions into the specific product
specifications driven by ambitious EU legislation
and by companies taking on the responsibility. This
is the only way we can ensure that the goals for high
energy e iciency levels are put into practice in the
production and supply chain. If green legislation
is not ambitious enough and is not embedded in
the processes and procedures at a company, city or
country level, we will not reach the global climate
targets set out.
In conclusion, the potential of investing in energye
icient and sustainable solutions is evident, but
there is a need for legislation to overcome the
barrier which the higher cost for raw and recycled
materials poses. The legislation should support
green initiatives and products, so the cost di erence
is only minimal – because, in the end, the initial cost
drives the decision to buy for the majority of owners
and developers.
