Building an energy-efficient home is a long-term win for your wallet, your comfort, and your future.
At Dunn & Stone Builders, we design semi-custom homes across the greater Houston area that feel good to live in and cost less to run.
That means thoughtful orientation on your homesite, insulation that actually pulls its weight, tight air sealing, high-efficiency HVAC systems, and materials that work as hard as you do. Add in energy-wise lighting, water-saving systems, and solar-ready planning, and you get a home that performs beautifully from day one.
This guide walks you through the building principles we use every day to help families create homes that stay comfortable, durable, and efficient for years.
Building an energy efficient house starts with thoughtful planning. Smart layouts, passive solar design, and careful modeling help lower a home's energy consumption long before the construction process begins.
(If you're living in Houston and looking to build a home, here is a helpful list of the best builders in the Houston area.)
When the home's structure, insulation, and other systems are designed to be energy-efficient, homeowners can save money and enjoy a more comfortable home.
Energy modeling gives homeowners a clear picture of projected energy use, helping build energy efficient homes that outperform code and often lower utility bills.
Fewer drafts. Less heat loss. Steadier temperatures. More sunlight and natural light where you want it. These early decisions lead to a high performance home that costs less energy to heat and cool.
Proper orientation uses the sun’s energy to your advantage. South facing windows capture natural heat in cooler months and reduce energy consumed by the heating system.
In the summer, shade trees and strategic overhangs help block infrared light, lowering air conditioning demand. Thoughtful placement creates natural cooling, reduces energy loss, and strengthens the home's energy efficiency in our local climate.
Passive solar design brings in natural light while reducing dependence on fossil fuels and mechanical systems. South-facing windows, skylights, and well-planned overhangs let your home absorb heat when needed and shed it when temperatures rise.
With less work required from the HVAC system and cooling systems, homeowners gain measurable energy savings and a more energy efficient home.
Well-placed windows and skylights brighten living spaces throughout the day, lowering the need for artificial lighting. More sunlight equals less energy use — and it makes rooms feel bigger, cleaner, and more inviting.
This is one of the simplest ways to save energy cost effectively while elevating the look and feel of the home.
Choosing the right type of insulation is one of the most powerful ways to boost a home's energy efficiency.
A well-insulated home holds conditioned air longer and reduces air leakage, which means less strain on heating and cooling equipment. High-performance insulation is key to building an energy efficient house that performs year-round.
Spray foam delivers a high R value and doubles as an air sealing method. It also expands to fill gaps, reducing air leakage and helping the home use less energy. Plant-based polyurethane foams and systems like insulated concrete forms support ultra efficient homes and offer dependable thermal protection in both warm and cold climates.
Continuous insulation wraps the home in a thermal blanket, reducing thermal bridging and creating a more airtight building envelope. This approach strengthens home energy efficiency, stabilizes indoor temperatures, and reduces space heating and cooling demands.
Insulating the foundation stops energy loss through the ground. It also helps maintain stable temperatures inside the home, an important feature for high performance homes designed to save energy year-round.
Air sealing plays an outsized role in reducing energy loss. Minimizing air leakage keeps conditioned air inside and humid outdoor air out. This is essential in Houston’s climate and supports a home energy efficient enough to rival net zero home performance.
An airtight building envelope is one of the most effective ways to improve energy efficiency. Caulking, gaskets, spray foam, and construction tapes reduce gaps that drive up heating and cooling costs.
High performance windows and properly sealed doors stop air leakage, protect against moisture control issues, and help maintain fresh air through controlled ventilation.
Energy recovery ventilators keep fresh air circulating while wasting less energy. Proper installation matters: poorly installed windows or air conditioners can undermine home energy and increase electric bills.
Moisture control prevents mold, protects indoor air quality, and preserves structural integrity. In airtight homes, balanced ventilation — often with an ERV — keeps humidity levels in check and reduces greenhouse gas emissions tied to excessive energy use.
Blower door testing identifies leaks early, helping energy efficient builders correct issues quickly. This step supports long-term durability, lower utility bills, and a more energy efficient house overall.
Energy efficient windows and insulated doors strengthen the thermal envelope, reduce energy loss, and keep indoor temperatures consistent. These upgrades improve comfort, protect finishes from UV exposure, and help homeowners save money over time.
High performance windows use low-E coatings to filter infrared light and reduce heat gain while still letting in natural light. They play a major role in lowering energy consumed by heating and cooling systems and are a core part of any net zero home strategy.
Insulated fiberglass or composite doors absorb heat less readily than metal options and increase the home’s energy efficiency. They work alongside energy efficient windows to reduce overall energy use.
Even the best products require proper installation. A tight seal prevents air leakage and strengthens the airtight building envelope — one of the biggest contributors to home energy savings.
Heating and cooling make up a large portion of a home's energy use — often close to 50%, according to the Energy Information Administration. Choosing efficient systems is essential for an energy efficient home.
It's a good idea to first make sure your heater or furnace is working properly. Here are some common furnace problems to look for. Fixing these will ensure your HVAC system is working at top efficiency.
Air source heat pumps move heat instead of creating it, making them far more energy efficient than traditional heating and cooling equipment. A modern heat pump can significantly reduce greenhouse gas emissions, limit reliance on fossil fuels, and improve comfort in every season.
Smart thermostats optimize HVAC system performance and reduce unnecessary energy use. Set schedules, remote control, and temperature zoning all help lower energy bills throughout the year.
Zoned systems cool or heat rooms individually. This reduces energy consumed in unused spaces and delivers more comfort with less energy.
Lighting is a simple, high-impact way to save energy and improve the look of your home. There are some great options for energy-efficient lighting.
LED lights use far less energy and last much longer than traditional bulbs. They also give off less heat, easing the demand on cooling systems during hot months.
Open layouts, strategic window placement, and thoughtful design let more natural light flow through the home. This reduces dependence on artificial lighting and creates a brighter, more inviting space.
Timers, dimmers, and smart switches reduce unnecessary energy use and support homeowners who want more control over their home energy.
Sustainable building materials help reduce environmental impact, minimize maintenance, and improve long-term durability. They also boost resale value and reduce the energy consumed during the construction process.
Products containing recycled content help conserve natural resources and reduce waste. These materials often require less energy to produce and support more energy efficient construction overall.
Thermal mass materials — such as concrete and masonry — absorb heat during the day and release it slowly at night. This maintains steady temperatures and reduces strain on heating and cooling systems.
Cool roof reflects light and absorbs less heat, reducing attic temperatures and lowering air conditioning demand. This upgrade increases comfort and lowers a home's energy consumption during long Texas summers.
Adding renewable energy sources is a major step toward building an energy efficient home and lowering reliance on fossil fuels.
Installing solar panels reduces electric bill costs, increases energy independence, and supports net zero home performance. Homeowners may qualify for tax credits, including the residential clean energy credit, which can significantly lower out-of-pocket expenses.
Battery systems store excess solar energy for nighttime use or outages. They increase stability, reduce dependence on the grid, and work especially well in homes with a heat pump or air source heat pumps.
If a roof isn’t suitable for solar, community solar programs provide a way to benefit from renewable energy without onsite installation.
Water heating accounts for nearly 20% of a home’s energy use. Upgrading to efficient systems significantly improves a home's energy efficiency.
A heat pump water heater uses surrounding air to heat water, consuming far less energy than traditional models. These systems help homeowners save money year after year.
Tankless systems heat water on demand. This reduces energy loss and provides unlimited hot water without maintaining a full tank around the clock.
WaterSense fixtures, low-flow showerheads, and efficient toilets reduce water use and lower utility bills without compromising performance.
Another way to improve energy performance is to make some changes to your yard. There are a few simple landscaping tricks you can use.
Well-placed shade trees block harsh summer sun, lowering cooling loads and helping reduce the home's energy consumption.
Trees and shrubs protect the home from winter winds, reducing energy loss and supporting more stable indoor temperatures.
Drought-tolerant plants reduce water use, require less maintenance, and support sustainable landscaping.
Tax credits and incentives make it easier for homeowners to invest in energy efficient upgrades that save energy long-term.
This federal credit helps offset the cost of renewable energy upgrades like solar panels and heat pumps. It also plays a meaningful role in making renewable energy more accessible.
Texas programs, including ones influenced by the Inflation Reduction Act, support energy efficient upgrades. Dunn & Stone Builders helps families explore these resources and select upgrades that deliver meaningful energy savings.
