Sustainable Home Design Tips

US-based real estate company RedFin recently looked at how you can make your home more sustainable and environmentally friendly. From interior design and gardening to energy-saving techniques and general green building techniques, they considered various eco-friendly tips and ideas from experts in the field.

Here’s what we learnt:

1 Begin Small

A common misconception is that creating a sustainable home is expensive. Even though some sustainable techniques may be more costly than conventional ones, this need not always be the case.

Small changes like switching to LED light bulbs could be the first step in a sustainable design strategy.

Another straightforward approach to creating a more environmentally friendly environment in your house is adding some plants.

Minor, daily adjustments you make to your environment and way of life over time can make a big difference. This method can assist in giving you the ideal start on the road to an environmentally friendly home.

2 Reuse outdated items

Repurposing existing items is one of the most sustainable things you can do. And it’s also cheaper.

Antique furniture can add an incredible vintage feel to your house while extending its life. Check out the Bajan antique group on Facebook for some unique furniture or other Barbados-based resale groups on the platform. Or pop along to Andy Tempro auctions and pick up a bargain.

The advantages of buying fewer new items include using less energy and, consequently, lower carbon emissions and financial savings.

If you are using the services of an interior designer, explain that you want to utilise items that you already own or are keen to incorporate older items into the design.

When making your home more sustainable, keep three things in mind:

  • less is more
  • quality over quantity
  • all the products deserve a second life.

3 Employ Natural Resources

As part of a sustainable design project, try to incorporate as many natural resources and materials as feasible. Not only is this beneficial to the environment, but your health is also improved. Speak with your architect and contractor to see what is available and possible in Barbados.

Materials that cause more significant environmental harm are those whose complex manufacturing processes require considerable energy.

For example, concrete, glass, and steel are significantly less natural than wood, stone, and bamboo.

Rattan, cane, raffia, and other comparable materials are good sustainable options for furniture, lighting fixtures, and other home furnishings. They also enhance your tropical home design with natural textures, finishes, and tones.

4 Locate Regional Resources

The transportation of materials and goods worldwide accounts for a sizeable portion of the world’s carbon emissions. So it makes sense to use materials from regional or local sources.

Not only does this shorten the route resources take to reach your location, but local stone, timber, and other building materials can be more tolerant of your climate and environment.

Additionally, you are working with regional manufacturers, suppliers, and craftspeople, contributing to the regional economy and trade.

5 Build what you need

Many of us want to build a large house, reflecting our wealth, status, and desire for space. However, rooms are built serve the same purpose. For example, many modern homes include a formal dining room, breakfast nook, bar counter, and outdoor dining terrace or gazebo.

Real sustainability is creating a home that is effective in meeting your needs. A compact, efficient home consumes fewer resources and materials and requires less energy to run daily.

6 Bring Nature Inside

Discover ways to apply passive strategies to your home, like natural ventilation and daylight and sun-shielding techniques, which are particularly helpful in tropical regions such as Barbados.

Re-establish your connection to nature using biophilic design. Biophilic design is an intentional design approach that incorporates nature into a building. The word biophilic relates to a more intentional connection with natural elements.

7 Include A Rain Garden

When designing your new home, consider the garden area too.

Landscaped gardens around your home are better than hardscaping, like concrete paving. In addition, trees and shrubs will make your home cooler as they encourage cooler air in and around your house.

Additionally, gardens offer more opportunities to collect rainwater. Rainfall on hard surfaces drains into stormwater management systems, which may eventually reach the ocean. However, this stormwater should go into the ground, replenishing groundwater reserves.

Ask your contractor about adding a rain garden to your plot. Native plants are typically placed in a slight depression on a property to create a rain garden. It needs to be close to one of your property’s low points, allowing water to flow towards this dip.

Typically, the soil’s composition encourages water to drain quickly into the ground. As a result, it stops rainwater from collecting and turning into a mosquito breeding ground.

During the rainy season in Barbados, ensure your rain garden is large enough to handle the amount and intensity of the rain and can drain adequately.

8 Use indigenous plants

One excellent technique to make your home more environmentally friendly is to use native plants in your garden.

They are suitable for the local climate and habitat and often do not require much upkeep and care. As a result, there is no need for additional fertilisers, insecticides and supplementary irrigation. They are also more sustainable and eco-friendlier than a lawn.

Native plants grow quickly and adapt to the environment in the area. Additionally, they offer homes for the local birds, insects, and other indigenous wildlife species.

9 Keep the Natural Site

Minimising your influence on the construction site is a great place to start when building a new house.

Find any established plants and natural water features and make an effort to preserve them. The home and garden should ideally have as little impact on the site’s natural topography.

10 Utilise solar power

Using renewable energy sources is an excellent method to lessen our reliance on fossil fuels.

Solar energy is one of the most widely available renewable energy sources in residential applications. It is widespread in tropical areas and becoming more popular in Barbados.

Adding photovoltaic (PV) panels is an excellent approach to reducing your carbon footprint and electricity usage. Compared to fossil fuel sources, the price of solar energy also tends to fluctuate far less. Consequently, there are also financial advantages there.

National Renewable Energy Laboratory report states that each household that switches to solar energy could stop up to 7.7 tons of toxic greenhouse gasses from being released into the atmosphere.

Solar thermal water heating is another option.

Whether you are building something new or renovating something old, focus on sustainability, using recovered materials and working with nature provides exciting environmental and economic benefits that will improve the quality of your home and its inhabitants.

How to keep your Barbados home cool

When planning your new home in the Caribbean, your priority might be the design and aesthetics. You want your property to have the “wow factor”, with cutting-edge architecture that makes it stands out from the neighbours. 

You might want to incorporate your environmental credentials and build with sustainability in mind at every step. Or your property could be all about the view!

Whatever your design motivation, when building in the Caribbean, your final design must solve the problem of how to keep cool. 

During the summer months especially, the heat can become overwhelming. If you don’t want a huge electricity bill each month, you need to create a design responsive to the Caribbean climate with the maximum amount of shade and ventilation.

Many older colonial properties built in the Tropics tackled the issue with some clever design decisions we can still learn from today:

Courtyards: many houses were laid out around a courtyard, with arcades enabling residents to move from room to room in the shade.

Doors: typically very tall with small windows or postigos (blind doors) that could be opened to provide light and ventilation without disturbing the residents’ privacy by opening the whole door.

Ceilings: vaulted ceilings were not easy to build but were higher than flat ones and kept rooms cooler.

Mamparas: these swing doors, with decorative glass panels and fancy woodwork, were popular in the 1800s and allowed air to circulate between rooms.

So, if you’re considering building a home in Barbados or anywhere in the Caribbean, what principles should you consider? Here are our top suggestions to make your Barbados house cool throughout the year without relying too much on air conditioning.

1 Orientation

Where you place your home on your plot of land will determine how well you can maximise the prevailing winds and protect against sun exposure.

Architropics explains that the prevailing winds generally come from the east in the Caribbean, with the sun path passing primarily to the south for most of the year. The reason for this sun pattern is because the Caribbean islands are north of the equator. 

If your design is rectangular, they recommend considering orienting the length of your building east to west. This orientation minimises exposure to the morning and evening sun. 

However, the wish to minimise sun exposure needs to be weighed with taking advantage of the all-important prevailing breeze. Therefore, determine which rooms need the most ventilation and locate them towards prevailing winds.

Don’t forget to ask your architect about openings, roof overhangs, and where to locate trees and vegetation to create as much shade as possible.

2 Shade

Ask your architect for a shading strategy. Not only will this limit the sun heating walls and surfaced, which then transfers to interior spaces. Direct sunlight through windows, for example, can significantly increase the internal temperature of your home. 

In Barbados, as the sun’s path tracks to the south for most of the year, horizontal shading is ideal for north and south-facing walls and openings. 

A small roof overhang might protect the north-facing wall of a single storey home. At the same time, you will require a much larger overhang to shade an entire southern wall.

As with older home styles, verandas and patios can shade northern and southern facing walls when the sun is at its highest during the middle of the day.

Architropics recommends that walls facing east and west have vertical shading such as screens or vegetation to protect them from solar heat gain.

Large trees can also provide general, creating cooler air temperatures entering the house.

3 Ventilation

To create a comfortable indoor temperature without resorting to air conditioning, you need to have a constant, unobstructed flow of cool air passing from one side to the other. 

This process is called cross ventilation and should be incorporated into the design process. You require a minimum of two openings on different sides of each room. This encourages air movement in the entire room and not just the corner. 

For example, large casement and louvre windows and doors allow air to pass through almost 100 per cent of their opening. On the other hand, sash or sliding windows permit less than 50 per cent of its opening. 

And make sure windows are protected in some way so they can remain open during rainfall or overnight without compromising your security. 

It is also recommended that you include vents at or near roof level to let hot air escape and draw cooler air through lower-level windows. This technique is called the stack effect.

4 Materials and Construction

Concrete blocks, in-situ (cast-in-place) concrete, or masonry bricks are the preferred choice throughout the Caribbean. However, they absorb heat during the day and release this into the room at night. Lightweight materials do not store heat and are better for their thermal qualities. 

Discuss the options with your architect but remember that concrete walls offer other benefits such as their resistance to hurricanes, flooding and mould. And if you use a mass wall system, shade them with roof overhangs, screens or shady trees.

5 Roof Design

As the most exposed area in your house to the sun’s rays, your roof is responsible for radiating considerable heat into a home. 

Architropics recommends using light-coloured, reflective roofing materials to reduce the amount of heat passing through the interior.

They explain: “A double roof system also has benefits in reducing the heat that enters your home. Double roofs comprise two layers of roof. An air space typically separates the two layers. Hence, the upper roof layer protects the lower roof from direct sun exposure. This system significantly reduces the heat gain on a roof”.

Other solutions to keep your home cool include high roofs and steep pitches, which allow the heat to be safe from people in the space below.

6 Exterior Spaces

Within your new home, you’ll want to include plenty of outside spaces such as patios, verandas, and courtyards. These will be usable throughout the year and can provide shade to interior areas of the house.

Ensure that you partially or entirely cover exterior areas to provide both shade and protection when it rains.

7 Energy Efficiency

Shockingly, over 20 per cent of the world’s energy usage goes towards construction and maintaining houses, apartments and other residential buildings. 

So, when building your new home in Barbados, ask your architect to use more energy-efficient strategies and practices such as:

  • Solar thermal panels for heating water
  • Solar/photovoltaic for electricity generation
  • Low wattage lighting
  • Water-saving devices
  • Rain-water storage

If your house is well designed, you should avoid or limit your use of air conditioning systems to keep your home cool throughout the year.
