What is an Energy Efficient Home?

An energy-efficient home is a house design and construction that focuses on reducing energy consumption and minimising environmental impact. It aims to use electricity sourced from renewable energy sources, optimises heating and cooling systems, and incorporate sustainable materials for long-term sustainability.


An energy-efficient home is a house that uses less energy. It can do this in many ways. One way is by having good insulation to keep the heat in or out. Another way is using solar panels and other renewable energy sources for power.

These homes are not just great for the planet, but they also help save money on power bills.

Why is it Important?

Having an energy-efficient home is a big deal. Increased building standard require homes to perform well in terms of thermal comfort, which helps to cut down your power bills. You also help the Earth by making less carbon go into the air. Plus, you get to live in a comfortable house that does not get too hot or cold.

Making sure your home seals are tight is vital for this! Using suitable materials when building can make your home green and budget-friendly simultaneously!

Designing an Energy-Efficient Home

Designing an energy-efficient home involves knowing your local climate, utilising passive design techniques, incorporating renewable energy sources, and effectively managing heating and cooling systems.

Utilising Passive Design

Passive design is an intelligent way to make a house energy efficient. This design uses natural ways to light, heat and cool your house. It also helps keep the inside air fresh and lowers the need for artificial heating or cooling systems.

In the design stage, it is vital to position your home to suit the path of the sun. This allows your home's windows, walls, and floors to store heat from the sun in winter. Eaves also help block out heat when it's hot outside in summer. You might use shading devices like screens on your windows for even better results.

You save a lot of money on energy bills with passive design. Also, because it mainly uses natural light, it helps reduce electricity usage during the daytime.

Incorporating Renewable Energy

Using clean power saves cash and the Earth. Solar panels are a great solution for this. You set them on your roof. They capture sunlight and turn it into energy for your home.

Another choice is to buy green energy from the power grid. This helps cut down on the reliance on fossil fuels that contribute to greenhouse emissions. Plus, these methods ensure you always have power even if there's an outage.

Managing Heating and Cooling

Managing heating and cooling is a key part of creating an energy-efficient home.

  1. Choose an energy-efficient heating system. Avoid old systems, as they use more power.

  2. Look for appliances that save energy. These are often called "Energy Star" products.

  3. Install insulation in walls and roofs to trap heat inside. This can keep your house warm in winter and cool in summer.

  4. Use good curtains or blinds to stop heat from the sun burning up the house during summer days, but let it in during winter days.

  5. Set up fans around your house to create air movement in the home..

  6. Look at getting a smart thermostat. It lets you control when heating or cooling turns on and off, even when you're not home.

  7. Keep doors inside your house open so air can flow freely.

  8. Be an active inhabitant in the home and open windows to allow natural breezes to cool the home.

  9. You could also look into landscaping solutions, which can help shade external walls in Summer.

  10. Make sure windows and doors have seals that prevent air from sneaking through.

  11. Use thermal insulation to protect against too much heat during summer or cold during winter.

Building an Energy-Efficient Home

For an energy-efficient home, it is crucial to use eco-friendly materials, ensure proper insulation and sealing, and opt for energy-efficient lighting and appliances.

Using Eco-Friendly Materials

Eco-friendly materials help build a green home. They are good for you and the earth, too. You can use materials such as timber frames, that are a renewable and sustainable building material.

Proper Insulation and Sealing

Insulating and sealing your home well makes it more energy efficient.

  1. Choose insulation suited to your climate. Colder climates need materials with high insulation value and thermal mass.

  2. Use caulking and weather stripping. These methods keep out cold air and hold warm air in.

  3. Air sealing is key. A tight house saves energy and money.

  4. Go for energy-efficient doors and windows. They help control the temperature inside your home.

Energy-Efficient Lighting and Appliances

Choosing energy-efficient lighting and appliances is an essential step in designing and building an energy-efficient home. You can save a significant amount of electricity by selecting LED lights instead of traditional incandescent bulbs.

LED lights are long-lasting and use less energy while providing the same brightness level. When it comes to appliances, look for those with a high ENERGY STAR rating, as they are designed to be more efficient in energy usage.

This will help reduce your electricity bill and lower your carbon footprint.


Designing and building an energy-efficient home is crucial for the environment and can save you money on your energy bills. By incorporating passive design strategies, utilising renewable energy sources, and adequately managing heating and cooling systems, you can create a home that is both eco-friendly and cost-effective.

Choose sustainable building materials, ensure proper insulation and sealing, and opt for energy-efficient lighting and appliances to further enhance the efficiency of your home. With careful planning and consideration, anyone can achieve an energy-efficient home that benefits their wallet and the planet.


1. What are the benefits of designing and building an energy-efficient home?

Designing and building an energy-efficient home can help reduce your energy consumption, lower utility bills, and decrease your carbon footprint.

2. How do I design an energy-efficient home?

To design an energy-efficient home, consider factors such as insulation, window placement for natural light and ventilation, efficient appliances, and renewable energy sources like solar panels.

3. Can I build an energy-efficient home on a budget?

Yes, you can build an energy-efficient home on a budget by making intelligent choices in materials and appliances with high-efficiency ratings. A well designed energy efficient home will save you money in the long run with lower running costs.

4. What is the payback period for investing in an energy-efficient home?

The payback period for investing in an energy-efficient home varies depending on location, house size, local utility rates, and chosen improvements. Generally, it is estimated to range from 5 to 15 years.

5. Are there any certifications or standards for energy-efficient homes?

Yes, the National Construction Code prescribes a minimum thermal performance and BASIX standard for all new homes. An alternative pathway - NatHERS has also been created to provide a way to quantify the thermal performance of home designs. The minimum star rating is 6 Stars.
