Out with the Old
and in with the New
Decreasing your Footprint whilst Increasing your Savings
Many companies want to reduce
their carbon emissions whilst also
keeping costs low. Energy expert,
Michael McNerney, explains how
the Energy Services team works
alongside their clients to achieve this.
At Aramark, our Energy Services team
assist our clients in reaching this goal by
tailoring a solution that is suitable for
them. In this edition, we delve into some
recent projects undertaken by our Energy
Services team, who look to innovation and
technology to reduce carbon footprint and
increase return of investment.
The Energy Services team continuously
aim to provide effective and efficient
solutions for our clients and have been
at the forefront in finding solutions
that can be offered to businesses who
want to reduce their carbon emissions
whilst making savings. One of the most
opportune times to do this is during an
end-of-life capital equipment replacement.
A spotlight on
how we work:
To give an example of how we can
achieve savings and how we work, we
take a look at the factors involved with
replacing refrigeration systems, or chillers.
When equipment reaches the end of its
economic life, it can become unreliable
and costly to maintain. The key areas our
Energy Services team looks at is value
for money and environmental impacts.
The team conducts extensive research to
source best-in-class green solutions with
the right technology spec for the client.
Some of the important items to consider
are cost of ownership, refrigerant gas type,
physical size, energy consumption and
carbon emissions reduction.
Why is it worthwhile replacing
an old model for a new one?
Operating refrigeration systems creates
a carbon footprint and many older
HFC refrigerants have medium-to-high
global warming potential. Consequently,
legislation and operational best practices
have increasingly looked towards reducing
the environmental impact of these gases.
A growing focus on the environmental
impact of refrigerants is fuelling demand
for solutions that can provide satisfactory
cooling performance with a lower impact
on global warming. There are also
indirect carbon emissions released when
the refrigeration system consumes grid
electrical energy generated from power
stations. The less energy consumption
a chiller makes then, the better for the
environment.
Smart Technology -
Hybrid Heat Pump
The same idea applies for boiler
equipment, with the introduction
of “Hybrid” heat pump technology.
Hybrid heat pump technology extracts
energy from the air and uses an optimal
combination of renewable and traditional
energy to heat a building. This ensures the
highest efficiency. Smart programming
of this technology helps to save more
energy and substantially reduce carbon
emissions compared to a traditional
boiler by automatically determining
the most economically and energy
efficient combination based on outdoor
temperatures and indoor heat capacity.
Undertaking and presenting a cost-benefit
analysis that demonstrates how to achieve
class-leading emissions reductions while
maintaining the lowest cost of ownership,
highlights opportunities to clients. Instead
of opting for standard replacement
equipment at a standard price, clients
see the benefits of investing in energy
efficiency equipment with environmental
credentials which also produces savings.
The payback to clients can also be quicker
than a standard machine investment. The
Energy Services team keep environmental
footprint at the forefront when proposing
new investments while also looking to
newly developed technology to extend the
equipment life-cycle and provide a quick
turnaround on ROI.
