Moving to a new home is an exciting adventure, but it also presents an excellent opportunity to make choices that can positively impact your budget and the environment. One crucial factor to consider is energy efficiency.
Whether you’re planning to renovate an old home, purchase a custom-built home, or your home was designed and built as a green home, there are opportunities all around to create an environment that is energy efficient.
What is an energy-efficient home?
An energy-efficient home is designed, built, or retrofitted to use less energy while maintaining a comfortable and healthy living environment. There are several characteristics and features that contribute to the designation of a home as energy-efficient.
- Efficient heating and cooling systems use energy-efficient HVAC (Heating, Ventilation, and Air Conditioning) systems that meet or exceed industry standards for efficiency. These systems are properly sized for the home’s needs and regularly maintained.
- Water-efficient fixtures, like low-flow toilets and faucets, help reduce water consumption and the energy needed to heat water.
- Energy-efficient lighting such as LED or CFL (Compact Fluorescent Lamp) consumes significantly less electricity.
- ENERGY STAR rated refrigerators, washing machines, and dishwashers use less energy while providing the same level of performance.
- Some energy-efficient homes incorporate renewable energy sources like solar panels or wind turbines to generate electricity and reduce reliance on non-renewable energy sources.
Energy-Efficient Home Designs
An ultra-efficient home design combines state-of-the-art, energy-efficient construction, appliances, and lighting with commercially available renewable energy systems, such as solar water heating and solar electricity (source). These home designs are leading the charge toward a greener, more environmentally friendly future and offer unique spaces to dwell. Example designs include:
Passive House: Homes built with high levels of insulation, airtight construction, and advanced ventilation systems. They rely on passive solar gain and heat recovery to maintain a comfortable temperature without traditional heating or cooling systems.
Net-Zero Energy Homes: Net-zero homes produce as much energy as they consume over the course of a year.
Zero Carbon Homes: Aim to minimize carbon footprint by using carbon-neutral or low-carbon construction materials, integrating renewable energy sources, and implementing energy-efficient systems.
Earthship Homes: These off-grid, self-sustaining homes are typically constructed with natural and recycled materials like tires, glass bottles, and adobe. They use passive solar heating and cooling, rainwater harvesting, and solar power to operate completely off the grid.
Green Roofs and Living Walls: Green roofs and living walls incorporate vegetation into the building envelope, providing natural insulation, reducing energy consumption, and improving air quality.
Prefabricated and Modular Homes: Prefabricated and modular homes can be designed with energy efficiency in mind. These homes are constructed in controlled environments, reducing waste and ensuring precise insulation and sealing.
Tips to make your current home energy efficient?
Transforming your current home into an energy-efficient oasis is a smart investment that pays dividends in multiple ways. Taking all or even a few of the following tips will improve your home’s energy efficiency, lower your utility bills, reduce your carbon footprint, and create a more comfortable living environment for you and your family.
Low-Cost Ways to Get Started
- Start with an energy audit to identify areas for improvement and optimize energy usage further.
- Seal gaps, cracks, and leaks
- Update existing windows with caulking and weatherstripping
- Close interior blinds, drapes, or shades to block the sun and heat during warm weather
- Change air filters
- Replace incandescent bulbs with LED
- Install Smart Thermostats and Home Automation
Higher-cost options for a bigger impact
- Energy-efficient building materials, such as insulated concrete forms (ICFs) or structural insulated panels (SIPs), can enhance a home’s energy performance.
- Update or replace insulation will help maintain a consistent indoor temperature, reducing the need for heating or cooling.
- Install new windows. Heat gain and heat loss through windows are responsible for 25%–30% of residential heating and cooling energy use (source).
- Replace old appliances with ENERGY-STAR appliances.
Energy-efficient landscaping for Texas homeowners
Energy efficiency isn’t just for inside your home. By incorporating these energy-efficient landscaping practices into your outdoor space, you can conserve water, reduce heating and cooling costs and add beauty to your home (source).
- Opt for plants native to Texas or well-adapted to the local climate. These plants require less water and maintenance, which can save you time and money on irrigation.
- Strategically plant trees and shrubs near windows to provide shade and block direct sunlight, reducing the cooling load on your home during hot Texas summers.
- Apply mulch around plants and trees to retain soil moisture, reduce weed growth, and maintain soil temperature. This conserves water and minimizes the need for frequent watering.
- Use drip irrigation or soaker hoses to water plants directly at the root zone, reducing water waste through evaporation or runoff.
- Install a rain sensor or smart irrigation controller to adjust watering schedules based on weather conditions, preventing overwatering.
- Consider ground covers like native grasses or low-growing plants that require minimal maintenance and water, reducing the need for mowing and irrigation.
- Install energy-efficient outdoor lighting fixtures that use LED bulbs, which consume less energy and have a longer lifespan than traditional incandescent bulbs.
Government Incentives for Energy-Efficient Homes
Renovations and improvements to make your home more energy-efficient can add up, but there are government incentives you can take advantage of to offset the costs. Here are some common incentives you might find in your area:
Tax Credits: Many governments offer tax credits for energy-efficient home improvements. These credits can be applied to expenses related to insulation, windows, doors, roofing, heating and cooling systems, solar panels, and more. The amount and eligibility criteria for these credits vary by region and can change from year to year.
Rebates: Utility companies and government agencies sometimes provide rebates for purchasing and installing energy-efficient appliances, HVAC systems, and insulation. These rebates can significantly reduce the upfront cost of upgrades.
Energy Star Rebates: Many countries have Energy Star programs that promote energy-efficient appliances and products. These programs may offer rebates for purchasing Energy Star-certified products.
Net Metering: For homeowners installing renewable energy systems like solar panels, net metering programs enable them to sell excess electricity back to the grid, reducing or eliminating their electricity bills.
To take advantage of these incentives, it’s essential to research the offerings specific to your region, consult with local government agencies, utility companies, and tax professionals, and ensure you meet the eligibility criteria. Additionally, keep in mind that incentive programs may evolve and change, so staying informed about updates and new opportunities is crucial when planning energy-efficient home improvements.
Whether you’re starting from scratch with a new home or looking to enhance the efficiency of your current abode, energy-efficient solutions are numerous and impactful. By embracing these principles and practices, you not only save money on utility bills but also reduce your carbon footprint, create a healthier living environment, and contribute to a more sustainable future.
As you embark on your journey towards an energy-efficient home, remember that every step counts, and together, we can make a significant difference for generations to come.
