Sustainable Home Design Features
Passive Heating and Cooling
Passive heating and cooling is a critical aspect of sustainable home design, but it can also be one of the more complex features to design and execute. Passive heating and cooling relies on the sun’s energy, insulation, air flow, and natural ventilation to maintain a comfortable temperature. This eliminates the need for direct energy consumption and therefore reduces greenhouse gas emissions.
Active Solar Heating is achieved through the use of solar panels, evacuated tubes and other active solar thermal collectors. This energy is then used to directly heat the home by transferring energy to a storage tank, where it can be released into the house. Active solar heating is ideal for climates with long, hot summers.
Passive Solar Heating is achieved by utilizing architectural elements such as large windows, strategically placed skylights, and reflective surfaces. These features absorb and store solar energy during the day, releasing it at night to help maintain a comfortable internal temperature – even in cooler climates.
Insulation is critical for both active and passive heating and cooling. Insulation helps to keep cold air out during the winter, and warm air out during the summer. Walls, roofs, basements and attics are all common areas for insulation installation.
Air Flow is another important element in passive heating and cooling. Intentionally designed air flows within a home can make use of natural cooling techniques such as convection, thermal chimneys and stack ventilation. This can reduce the need for air conditioning by providing natural ventilation within the home.
With careful planning and design, sustainable home design can provide safe and comfortable living conditions for your family while also lowering your energy bills and reducing your carbon footprint. The table below illustrates some of the typical energy savings associated with passive heating and cooling techniques.
| Technique | Typical Energy Savings (kWh/m2a) |
|---|---|
| Passive Solar Heating | 40-60 |
| Active Solar Heating | 40-150 |
| Insulation | 15-35 |
| Air Flow | 25-35 |
Renewable Energy Sources
When designing a sustainable home, the use of renewable energy sources is key. Renewable sources like solar, wind and geothermal power provide clean energy and help reduce air pollution and greenhouse gas emissions. Here are the basics of sustainable home design when it comes to renewable energy sources.
Solar Power
Solar energy is one of the most common and cost-effective renewable energy sources used in residential home designs. Solar panels installed on the roof or in the garden collect sunlight and convert it into electricity. The electricity generated is then used to power household appliances, lights and other electronic devices.
Wind Power
Wind turbines are becoming increasingly popular for generating electricity in residential homes. This renewable source of energy collects wind energy through turbines and converts it into electricity. Wind turbines need sufficient wind to operate, making them most suitable for rural areas.
Geothermal Power
Geothermal energy is a renewable resource that uses the heat of the Earth to generate electricity. Heat pumps are installed underground, drawing on the Earth’s internal temperature to produce hot water and heat homes. This clean energy source is gaining popularity due to its efficiency and low emissions.

Reusing and Redistributing Waste
Sustainable home design is about more than slapping a few solar panels on your roof. It’s about making conscious decisions to reduce, reuse, and recycle – especially when it comes to waste. Here are some ways to practice sustainable home design by reusing and redistributing waste.
Repurposing
Repurposing is one of the simplest and most effective ways to practice sustainable home design. This involves taking something that would otherwise be thrown away and using it for another purpose. It could be as simple as turning an old dresser into a planter or as complex as constructing a coffee table from scrap wood. Either way, repurposing helps reduce waste and often adds character to a home.
Channels of Distribution
As good as it feels to keep an item out of the landfill, reusing materials can be even more satisfying when it’s done on a larger scale. You can post items on freecycle.com or Freegle, local Facebook Marketplace or other social media sites and apps to redistribute things you’re no longer using but that are still usable. This is a great way to get rid of items that aren’t suitable for repurposing, without sending them to the landfill.
Donating
Donating unneeded items is also a great way to practice sustainable home design. If you have things that are still in good condition, but don’t have much extra use, research local charities that accept donations. For example, Habitat for Humanity ReStores accept donations of gently used furniture and building supplies, which are then sold in their stores for discounted prices.
At the end of the day, sustainable home design is about reducing our impact on the planet. Reusing and redistributing waste is a great way to reduce our footprint and practice sustainability that goes beyond the walls of our homes.
Sustainable Landscaping
Low-Maintenance Landscaping
When it comes to creating a sustainable outdoor space, sustainable landscaping is key. Low-maintenance landscaping is a great way to create a beautiful garden while being environmentally friendly.
Three key elements to consider when designing your sustainable landscaping:
- Choosing the right plants for your climate and soil conditions
- Limiting water consumption
- Reducing or eliminating the use of pesticides and chemicals
When selecting plants, look for native species that can withstand the climate and soil conditions of your area. Consider the spacing between plants to create a balanced, efficient water cycle. Reduce water consumption with water-wise plants, such as cacti and succulents, that require minimal maintenance. To limit the need for chemical pesticides, use natural predators like ladybugs or wasps.
Aside from plants, you can also make your space more sustainable through the use of sustainable materials. For example, using locally-sourced materials for building retaining walls, decks, and pathways.
Sustainable landscaping is an important part of creating a healthy outdoor environment; with a few simple guidelines and careful selection of plants and materials, you can create a beautiful and sustainable outdoor space.
Organic Gardening
Sustainable landscaping and organic gardening are core principles of any sustainable home. Not only do they minimize reliance on herbicides and synthetic fertilizers, they also create gorgeous outdoor spaces with easy maintenance. Here are a few tips for getting started.
Choose native plants. Native plants are adapted to the local climate, so they’re well suited for local ecosystems. They also tend to be hardier and require less water, fertilization, and pest control.
Compost. Composting helps turn kitchen and yard waste into nutrient-rich soil. It’s also a more efficient way to dispose of organic waste. And you can use your own homemade compost as a fertilizer for your garden.
Grow food. Growing your own food is one of the most sustainable things you can do. Not only does it provide delicious and nutritious homegrown produce, it also prevents food waste and reduces the need to buy packaged items which often have unsustainable packaging.
Choose sustainable materials. If you’re landscaping with hardscaping materials, like walls, pathways, and patios, make sure they are made of sustainable materials like recycled concrete or reclaimed wood.
Limit your lawn size. If you can, opt for smaller lawns and more native greenscaping. Having a large lawn requires more maintenance and uses more water and fertilizer.
| Item | Comparison |
|---|---|
| Native Plants | Require less water/fertilizer |
| Composting | Nutrient-rich soil/no waste |
| Growing Food | Delicious/nutritious/reduces waste |
| Choose Sustainable Materials | Eco-friendly/recycled/reclaimed |
| Smaller Lawns | Less maintenance/less water |
Native Plant Species
Sustainable landscaping is one of the most important features of sustainable home design. The focus is on using native plants and species that are compatible with the local environment and ecosystems, minimizing the carbon footprint and preserving biodiversity.
Native plants are those that have been growing in a certain area naturally, and not been introduced by humans. They are particularly adapted to their environment and they provide food and shelter for wildlife, while also improving soil stability and nutrient cycling.
Benefits of Native Plant Species
- Drought-tolerant: Many native plants are extremely resilient to hot, dry and fluctuating temperatures.
- Low maintenance: Native plants require less water, fertilizer and pruning than non-native species.
- Pest/Disease resistance: Native plants are naturally resistant to pests and diseases.
- Long bloom period: Native plants often bloom for longer periods than non-invasive varieties.
Native plant species can also create a beautiful garden while providing a variety of habitats for wildlife, such as birds, butterflies and other pollinators.
When your garden is designed with native species you are helping to create a healthy and sustainable ecosystem, making your garden an important part of the biosphere.
The best way to create a sustainable garden is to mix native species with other plants to create a varied landscape. This will provide more stability and resilience against climate change in the future.
For example, planting a mixture of tall trees, shrubs, groundcovers, ferns and grasses can increase your garden’s biodiversity and create an interesting and vibrant space.
