Upgrade solution for external wall insulation
(EWI) retrofit.
EPC ALSO PROVIDES:
• Loft insulation
• Wall construction and insulation
• Age of construction
• Glazing
• Fuel type
• Boiler make and mode
Ordinarily insulation is the most cost-
effective way to target energy savings and
therefore offers users the quickest payback.
It is appropriate to mention that a
staggering 42% of energy input (for heating
or cooling) is lost through a roof or ceiling,
with 24% lost through external walls.
Even living conditions in properties
without outside energy source for
heating or cooling can be improved using
insulation, and by insulating a property
properly, you can slow down the rate at
which the sun heats your living
environment during the day and reduce
the rate at which the day’s residual heat
dissipates from your property in the evening.
It is of course advisable to plan and
design a comprehensive, whole-house
approach to energy efficiency, but while
it’s easier to install insulation during the
build phase, there are many methods to
retrospectively fit insulation to existing
or older buildings.
It’s another reason why choosing the
right insulation expert is essential to
your building project and helps to reduce
the reliance on appliances such as geyser
timers or blankets, gas heaters,
underfloor heating, air conditioning,
heat pumps and solar systems.
This is increasingly relevant especially
when you take into consideration the
likely introduction of Energy
Performance Certificates (EPCs) arriving
in South Africa in future.
Energy Performance
Certificates (EPCs)
What are EPCs and why are they
important to domestic or commercial
property owners?
EPCs tell you how energy efficient a
building is and provide you with a rating
from very efficient to inefficient. They
give an indication on how costly a
building will be to heat, cool and light
and what its carbon dioxide emissions
are likely to be.
For example, all domestic and
commercial buildings in the UK that are
on the market to buy or rent must have
an EPC. The energy performance survey
that is carried out for this purpose
highlights the ways building owners can
save money on their energy bills and
improve the comfort of their home or
commercial property. The EPC also
identifies what the energy efficiency
rating will be if improvements are made
and highlights cost-effective ways to
achieve a better rating.
