LONG-TERM ENERGY SAVING SOLUTIONS
REQUIRING INVESTMENTS
Many tips can be implemented in daily operations at no or little costs to deliver significant energy savings
on the short term. However, major additional energy savings can be further realised on the medium to
long-term through an intelligent use of technologies. In order to achieve significant reductions on CO2
emission on the long-term, as induced by Paris Climate agreement signed by 195 countries around the
world, hospitality businesses will also need to contemplate, and prioritise, further investments in energy
savings solutions.
This chapter provides a non-exhaustive overview of the key aspects that can be considered in a medium
to long-term strategy to raise energy efficiency, maximise energy and financial savings and reduce overall
CO2 emissions.
1. Upgrade the building’s thermal performances
The first element to consider to further raise energy efficiency and decrease overall energy consumption
on the long term is to invest in solutions that will increase the building’s overall thermal performances.
This is all about raising insulation, decreasing thermal shocks and avoiding infiltrations.
Windows insulation
Windows insulation is a key aspect that can easily generate savings which will rapidly offset initial
investments. A hospitality business that has simple glazing windows can save 20% on heating bills by
replacing the windows with doubled glazed units with high insulation properties.
Wall insulations
Wall insulations is an important element of the building’s thermal
performances, especially in older buildings. A hospitality business
with cavity walls can improve the wall’s insulation by filling the cavity
with insulation, generating up to 35% energy savings on space heating.
Several technical solutions exist in this case.
External walls insulation is another alternative to raise the building’s
thermal performances. In this case, an additional layer of insulation
is placed on the exterior of the wall. It helps reducing temperature
variations and eliminate cold bridges at the junction of walls, floors
and openings. This solution is often more costly, but deliver excellent
results in terms of energy savings.
Additional insulation can also be placed on the interior of the walls,
but such a solution reduces the space available inside the building
and is not always achievable, because of thermal bridging issues.
