Dallas Energy Data

Dallas, Texas

Elevation: 420 ft (130 m)

Location: 32° N, 96° W

Geography & Topography

This bustling city is located North of Texas and covers a whopping 385.8 square miles (that's almost as big as the entire state of Rhode Island!).

The topography of Dallas is pretty darn flat, with gentle rolling hills and sprawling prairies as far as the eye can see. The Trinity River runs right through the heart of the city, slicing it in half and providing a natural oasis for all sorts of critters, but also a natural oasis that's a relief from the heat.

Dallas is situated on a plateau that gradually slopes downward towards the Trinity River.

When discussing Dallas Energy Efficiency in relation to its geography and topography, there are two key things to keep in mind: rain and flooding, and urban heat sprawl.

Rain & Flooding

The city has taken various measures to mitigate the risk of flooding from the Trinity River. The most notable of these measures was the construction of the Trinity River Project, a massive undertaking that began in the early 2000s and involved the construction of levees, floodgates, and other infrastructure designed to protect the city from the river's wrath.

Despite these efforts, however, the risk of flooding from the Trinity River remains a concern, especially during periods of heavy rain or severe weather.

Urban Heat Island Effect

The urban heat island effect in Dallas is exacerbated by the large amounts of concrete and asphalt used in the city's buildings and infrastructure. These materials absorb and retain heat, causing temperatures to rise even higher, which is common in most cities. This can cause serious health threats. High temperatures can lead to heat exhaustion and heat stroke. It also causes challenges for cooling inside buildings.

To mitigate the effects of urban heat, the city of Dallas has implemented a number of strategies. One of the most important is the creation of green spaces, such as parks and gardens, which help to absorb heat and cool the surrounding area. Something that the Trinity River also provides. The city has also invested in programs to plant trees and other vegetation, which provide shade and help to reduce the amount of heat absorbed by buildings and surfaces.

To reduce the amount of urban heat on the exterior of a building, consider these energy efficiency improvements:

How Does Geography & Topography Effect Energy Efficiency?

Where you are located and the land around you can affect your buildings energy consumption in multiple ways:

Climate & Weather

Dallas has a humid subtropical climate, with hot and humid summers and mild winters. The city is prone to severe weather, including hurricanes and thunderstorms, which can cause flooding, damages to housing exteriors, and equipment.

The city experiences a lot of rainfall, particularly during the summer months.


Summer typically lasts from June to August and temperatures often exceed 100F. While there can be long stretches of hot and dry weather, thunderstorms are also common during the summer months, and these can bring heavy rainfall, hail, and even tornadoes.


Winter in Dallas typically lasts from December to February and are pretty mild. The average temps are in the 50s and 60s. However, it's not uncommon for temperatures to drop below freezing, especially at night. Snow is rare, but when it does occur, it tends to be light and doesn't last long.

Spring & Fall

Spring and fall are generally mild and pleasant in Dallas, with temperatures in the 70s and 80s. However, these seasons can also bring a fair amount of rainfall and thunderstorms.


Average humidity levels hover around 60-70%.

How does Climate Effect Energy Efficiency?

High temperatures and high humidity make air conditioning a challenge. Not only does your system have to cool the air but also removes the humidity. The added moisture in the air causes cooling systems to work harder which increases energy demand, consumption, and cost. This makes energy efficiency improvements more important for your location.

While humidity can make the summers feel even hotter, it can also contribute to the risk of mold growth and other moisture-related problems in homes and buildings.

Try incorporating shading and ventilation to reduce the need for air conditioning. Increased ventilation, moves air around reducing the risk of mold and moisture problems.

What are the Best Windows for Texas Weather?

Texas weather can be quite diverse, ranging from hot and humid summers to mild winters. The best windows for such conditions are those that offer superior energy efficiency, durability, and the ability to withstand extreme temperatures. Here are some top options:

Double-Pane Windows

Double-pane windows are a popular choice in Texas due to their excellent insulation properties. The two layers of glass with an air or gas-filled space in between help to reduce heat transfer, keeping homes cooler in the summer and warmer in the winter.

Low-E Glass Windows

Low-emissivity (Low-E) glass windows have a special coating that reflects infrared light, keeping heat inside during the winter and outside during the summer. This type of window is highly effective in improving energy efficiency.

Vinyl Frame Windows

Vinyl windows are known for their durability and low maintenance. They do not warp, rot, or fade, making them ideal for the fluctuating temperatures in Texas. Additionally, vinyl frames often come with built-in insulation, further enhancing their energy efficiency.

Impact-Resistant Windows

Given the potential for severe weather, including hurricanes and storms in some parts of Texas, impact-resistant windows are a smart choice. These windows are designed to withstand strong winds and flying debris, providing added protection to your home.

Composite Frame Windows

Composite windows combine the best features of different materials, such as wood and vinyl. They offer excellent thermal performance and are resistant to warping and moisture, making them suitable for Texas’s varied climate conditions.

Choosing the right windows for Texas weather can significantly improve your home's energy efficiency, comfort, and overall resilience against the elements.

Building Data and Efficiency

Benchmarking your building against relative averages is a great way to start. Determining where you stack up against your neighbors, will give you an idea of how much further you can cut costs on your energy bills.

Residential Averages

  • The average new home built in Dallas, Texas today is around 2,300sf.
  • The average residential energy consumed in Houston, Texas is about 1,094 kWh, per month. This is not exclusive to single resident homes.
  • The average utility rate is about $0.12/kWh.

Commercial Averages

What Are the Most Energy-Efficient Windows in Texas?

The most energy-efficient windows in Texas are those that provide superior insulation, reduce heat transfer, and are designed to handle the diverse climate conditions. Here are some top choices:

Low-E Glass Windows

Low-emissivity (Low-E) glass windows are among the most energy-efficient options. They have a special coating that reflects infrared light, keeping heat inside during the winter and outside during the summer. This helps to maintain a consistent indoor temperature, reducing the need for heating and cooling.

Triple-Pane Windows

Triple-pane windows offer excellent insulation by having three layers of glass with two air or gas-filled spaces in between. This design significantly reduces heat transfer, making these windows ideal for extreme temperatures. They also provide better noise reduction compared to double-pane windows.

Gas-Filled Windows

Windows filled with inert gases like argon or krypton between the panes are highly efficient. These gases are denser than air, providing better insulation and reducing heat transfer. This type of window helps to keep your home cooler in the summer and warmer in the winter.

Fiberglass Frame Windows

Fiberglass frame windows are known for their durability and energy efficiency. They do not expand or contract with temperature changes, maintaining a tight seal and reducing energy loss. Fiberglass frames also have excellent thermal performance, making them ideal for Texas weather.

Composite Frame Windows

Composite windows, made from a blend of materials like wood and vinyl, offer superior thermal performance and durability. They resist warping and moisture, providing a long-lasting, energy-efficient solution for Texas homes.

Investing in these energy-efficient windows can significantly reduce your energy bills, enhance your home's comfort, and contribute to a more sustainable environment.

Local Building Codes
