Energy-saving for Arizona heat How Awnings Reduce Energy Use

Awnings Help Arizona Homes Save Energy and Stay Comfortable

In the U.S., homes account for about 20% of primary energy use. Much of that energy goes toward heating and cooling.
In Arizona, extreme heat and intense sunlight drive up demand for air conditioning, especially during long, hot summers.

As sunlight pours through windows, solar heat gain rapidly increases indoor temperatures. Consequently, air conditioners run longer and harder.
This leads to higher electric bills and more energy consumption.

However, shading solutions like awnings offer an effective way to block heat and reduce cooling costs.
Therefore, homeowners in Arizona can benefit greatly from using awnings to improve energy efficiency.

This page outlines findings from a study by Oak Ridge National Laboratory (ORNL) on how operable awnings improve residential energy performance.

Why This Study Was Conducted

To better understand energy savings, researchers focused on how awnings reduce solar heat gain in homes.
Specifically, the study had three main objectives:

First, evaluate how much cooling energy awnings can help save
Second, test performance across multiple U.S. climate zones
Third, estimate annual energy savings for average homeowners

Study Approach and Methods

To ensure accurate results, the study used both real-world testing and computer simulations.
As a result, the research combined direct measurement with broader modeling to confirm effectiveness.

Field Testing
Awnings were installed on a real house equipped with monitoring systems.
Throughout the hot months, sensors recorded temperature, humidity, and energy use—indoors and outdoors.

Computer Simulations
Next, simulations were performed using prototype homes in several U.S. climates.
These homes had an average conditioned space of 2,377 square feet.

Furthermore, the simulations confirmed how shading impacted homes of different sizes and designs.
This helped reinforce findings from the field data and broadened the study’s relevance.

What the Study Found: Key Benefits for Hot Climates Like Arizona

1. Awnings Significantly Lower Cooling Demand

The most impactful finding was that awnings dramatically reduce solar heat gain.
By blocking direct sunlight, awnings keep interior spaces cooler.

As a result, homes use less energy for air conditioning.
In the test home, keeping awnings closed led to a noticeable drop in cooling-related energy use.

Moreover, the reduced cooling load meant HVAC systems operated more efficiently, saving both energy and money.

2. Awnings Provide Year-Round Energy Savings

Annual energy savings ranged up to 15% for cooling.
Notably, the highest savings were seen in hot climates such as Arizona.

Even in regions with milder summers, awnings still reduced energy usage.
Thus, they’re effective in a wide range of environments—not just the hottest zones.

3. Arizona Homes See the Biggest Gains

According to the simulations, homes in Arizona and other hot climates saw the largest savings.
In fact, some homes saved over 1,000 kWh annually just by using awnings.

These savings translate into lower energy bills and reduced environmental impact.
Additionally, the study confirmed awnings are one of the most cost-effective upgrades for heat-prone areas.

4. Minor Impact on Winter Heating

Although the main focus was cooling, the study also considered winter energy use.
While awnings slightly help block cold winds, heating savings were minimal.

However, they may help maintain more stable indoor temperatures during temperature swings.
Still, the biggest benefit remains in the summer cooling season.

5. Awnings Align with Energy Efficiency Programs

This research supports goals set by Energy Star and similar programs.
Because awnings reduce the need for mechanical cooling, they promote sustainable energy use.

Moreover, as a passive solar strategy, awnings help lower your carbon footprint without increasing electric load.
Thus, they are ideal for eco-conscious homeowners across Arizona.

Key Benefits of Awnings in Arizona’s Desert Heat

Lower Cooling Bills: Block sunlight before it enters your home
Improved Indoor Comfort: Reduce temperature spikes from intense sun
Protect Furnishings: Prevent fading of flooring and furniture caused by UV rays
Affordable Upgrade: Deliver long-term savings with minimal maintenance
Eco-Friendly Solution: Cut electricity use and greenhouse gas emissions
Works Statewide: Ideal for homes in both urban and rural Arizona areas

What Arizona Homeowners Can Do Next

If you’re ready to lower your energy bills, consider adding awnings to your home.
Here’s how to begin:

Consult a Local Expert: Find a shading professional who understands Arizona’s climate
Select the Right Awnings: Choose durable, UV-resistant awnings for maximum impact
Install Correctly: Ensure awnings are properly placed for optimal shading
Combine with Other Solutions: Use awnings along with efficient windows and insulation for even better results

Final Takeaway: Awnings Are a Smart Investment in Arizona

Clearly, awnings offer powerful benefits for Arizona homeowners.
They reduce solar heat gain, lower energy bills, and make homes more comfortable year-round.

Most importantly, they offer a simple and affordable way to fight the desert heat.
Whether you live in Phoenix, Tucson, or a smaller Arizona town, awnings can help your home stay cooler.

By taking action now, you can enjoy immediate energy savings and long-term comfort.
