Energy efficiency, building green, and reducing our carbon
footprint are all technical jargon we hear tossed around these days. We know
this overall concept is important, but do not always know where to start, or
how improving our homes in these ways benefits us. While substantial amounts of
information exist, the below will cover some of the basics of green energy, and
how to implement in a home.
From a technical standpoint, homes are given a HERS
score—which stands for Home Energy Rating. This rating is conducted by a
certified home energy RESNET (Residential Energy Services Network) rater. The index
is based on a score of 100—the lower the number, the more energy efficient the
home. The test compares a home to a similar-sized home for accurate comparison.
According to RESNET,
The U.S. Department of Energy has determined that
a typical resale home scores 130 on the HERS Index while a standard new home is
rated at 100.
- A home with a HERS Index Score of 70 is 30% more energy efficient than a standard new home.
- A home with a HERS Index Score of 130 is 30% less energy efficient than a standard new home.
So
what is the value in implementing these trends? From a resale perspective,
energy efficient features in a home appeal to buyers. The overall focus of the
next generation is to minimize our carbon footprint and be conscience of the
environment. The more energy-efficient a home, the more it is marketable to
potential buyers.
Additionally,
energy efficiency lowers costs. When a home owner strategically focuses on
lighting, heating, cooling, and any leaks of air in a home, the resulting
efficiency saves money. These improvements directly impact the bottom line of
home ownership expenses.
The
below areas are taken into consideration with a HERS test (from RESNET):
·
The
amount and location of air leaks in the building envelope
·
The
amount of leakage from HVAC distribution ducts
·
The
effectiveness of insulation inside walls and ceilings
·
Any
existing or potential combustion safety issues
Other variables that are taken into account
include:
·
Floors
over unconditioned spaces (like garages or cellars)
·
Attics,
foundations and crawlspaces
·
Windows
and doors, vents and ductwork
·
Water
heating system and thermostats
By
obtaining a HERS rating, homeowners may begin the process of improving their
homes and saving money. While not all of these improvements need to be made,
even minor changes will impact the current homeowner, as well as future resale
value of a home. This is a win-win situation: we can save money and reduce our
carbon footprint. These changes directly correlate to the resale value of a
home.
