How to Improve Energy Efficiency in Buildings

As energy efficiency in buildings becomes accessible, more people will be looking to make their businesses, places of residence and any other location green. 

These seven steps highlight key areas where making a
change to energy efficiency can help save money as well as improve the


The best place to take proactive steps is during the
planning stages. If you want to improve energy efficiency, you will need to
take into consideration your bottom line and your return on investment (ROI).
These two things will give you insight into how much you will spend and profit
from switching to energy-efficient systems and devices. 

Sustainable appliances and designs will save you money in
the long-run. Planning helps you budget to enhance your building’s

Energy Consumption

Another proactive step you’ll want to take is measuring your energy consumption as you make improvements. Measuring use alone will give you a better idea of how much power a building uses and what it uses it for. Some big data platforms help users track energy consumption over time.

After changes in energy resources and appliances, the
measurements of consumption should decrease. A tool like Energy Star’s Portfolio Manager can compare
buildings’ energy use. This resource will tell you what path to follow to
improve efficiency. 

Certified Appliances

Certified equipment and appliances are beneficial
alternatives to current, wasteful products. For instance, a refrigerator that
doesn’t have energy certifications will most likely be not as efficient as one
that does. Energy Star certifications will ensure better sustainability
for businesses. 

On average, an Energy Star certification will entail 30%
to 60% less energy use than a non-certified product. This decrease in usage
will lead to an improved ROI. You will want to keep an eye out for these
certified products, as they can cover a range of appliances. 


An HVAC system is beneficial to have in any building, but
it can come with unnecessary energy consumption. Leaks and damage can lead to
heating or cold air escaping, wasting money in the process.

A high-quality HVAC system is airtight. Energy-efficient
ones use outgoing air to heat or cool incoming air depending on the season.
This setup can significantly reduce the environmental impact of a building
while still providing the best ventilation for residents or employees. 


Similarly, insulation can improve heating and cooling too.
The outside design of a building can lessen the need for an HVAC system. If
this improvement isn’t currently possible, you can opt for keeping insulation

Leaks, again, can be a source of lost heating or AC, which can waste
money and worsen energy usage. Replacing any doors or windows that lead to
leakage is an easy fix that keeps the building insulated and using energy


Lighting is a major source of energy waste. Light bulbs
can use significant amounts of power, especially when they stay on for prolonged
periods. As an alternative, LED lights reduce energy usage and last up to 10,000 hours longer than
incandescents. Moreover, having sensors that automatically turn lights on and
off will save more electricity.

If you can, use natural lighting as much as possible. Some
buildings work well enough with natural lighting that they reduce the need for
artificial lights. Conversely, though, if your building faces the sun, you’ll
want to get awnings or solar screens to keep inside temperatures cool. 

Renewable Energy

The goal of energy efficiency in buildings is to help the
environment, and renewable energy can be a push in the right direction. Solar
and wind are the leading renewable sources at the moment, with solar becoming
more popular and less expensive.

When a building can make the switch to sustainable energy,
it will greatly improve the environment. This step could be small, like using
solar heaters instead of electric-powered ones. It could be a big step, too,
like switching entirely to geothermal. 

Improve Energy Efficiency In Your Buildings 

From ventilation to renewables, there’s plenty you can do to improve the efficiency of your building. When you make a move toward sustainability, you set yourself up toward a lifetime of cost savings and eco-consciousness.
