How To Design An Eco-Friendly Home
How Do I Build an Eco-Friendly Home?
In this day and age, we all recognise the benefits of having a more eco-friendly home but not many realise they can actively take steps to build a home that reflects these needs. There are several elements that contribute to an eco-friendly home. The first we usually think of is energy efficient. Consumption of energy through heating, hot water and electricity are all things that can be addressed. When building your home, using the right materials is key. Sometimes the upfront costs may seem daunting, but in the long run, it will all be worth it to live in a cost-effective and eco-friendly home that provides a sustainable way of living. It may be worth noting that some people are using Passivhaus planning packages, that have extremely high standards of insulation to achieve this, alternatively, we have created a list of suggestions that you could incorporate into your own designs below:
1. Eco-Friendly Lighting
By optimising the use of windows to increase the amount of sunlight in the home you can reduce the need for artificial lighting. Combine this with the use of eco-friendly LED lightbulbs and you could save up to £80 a year and reduce your carbon footprint. An LED light bulb can reduce energy consumption by 80-90% and last around 100,000 hours.
2. Install Water Saving Fixtures
On average, more than 6,300 gallons of water are wasted per household every year. By installing a few handy devices around the home you can save money and protect the environment. Devices such as low flow high-efficiency faucet aerators and water-efficient shower heads can make such a difference.
You could also install a greywater diverter that recycles water from showering or rinsing laundry into a storage vessel. The water can then be used to flush the toilet or water the lawn or garden. Just be sure to use environmentally friendly products that will not leave any harmful chemicals in the water, such as those from products with micro-beads, stain lifters, bleach, and soaps.
3. Invest In Proper Insulation.
By investing in proper insulation, you can keep your home cooler during the hotter months and warmer during the cold months, reducing the need to run your heating and cooling systems.
Heat rises so it is important to make sure you have effective insulation in the roof. You should aim to incorporate 270mm of mineral wool tucked between the joists and don’t forget to insulate the loft hatch.
You may wish to consider using structural insulated panels (SIPs) which consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). SIPs are manufactured under factory controlled conditions and can be made to fit nearly any building design. These panels are used as an alternative to a wood frame construction. The result is a house that is extremely strong, energy-efficient and cost-effective. Building with SIPs can save you time and money.
Make sure your windows can efficiently hold in the heat. More energy is often lost through the gaps around the window frames than the glass itself. The newest double or triple glazed windows are important to ensure your house is efficient.
4. Use Recycled or Sustainably Sourced Materials.
For this it helps to think outside the box. You can use recycled materials such as plastic in your home or natural products such as straw bale, sheep’s wool and lime. Sustainably sourced materials such as certified timber and materials with a low carbon footprint (such as how much carbon dioxide was produced when making and transporting the item) are also important to consider. Bamboo is very appealing to use for an eco-friendly house as it’s highly renewable being one of the fastest growing plants on the planet. Other examples that are less traditional include; recycled cork panels for flooring, recycled glass tiles, Newspaper wood and denim for insulation but we’re sure there are many more great materials you could include.
Another notable material that you may wish to use is Enviboards. Enviboards is a UK based company that offers a product called Fireboad which is a fire-resistant board made of materials like magnesium, sawdust and fibre cloth that can be used instead of timber for things such as wall lining, internal partitions, roof lining and underlay systems.
Of course, when discussing how to make your house more eco-friendly we couldn’t miss out solar panels. Contrary to popular belief, you do not need full sunshine for solar panels to work, which is good news for those of us in the UK, rather just natural daylight can be enough to provide some energy, although the more sunshine there is the more you get out of them. Solar power doesn’t release any greenhouse gasses and except for needing a source of clean water to function, it uses absolutely no other resources. Installing solar panels may be expensive but in the long run, saves a lot of money and energy consumption. It is much better for the environment as it is a clean source of energy helping you reduce your carbon footprint.
“In January 2020, the Government introduced a new scheme to pay households that install solar panels. The scheme, known as the smart export guarantee (SEG), pays households for solar energy they 'export'. This is electricity you generate, but don't use yourself, that is then pumped back into the national energy grid. The scheme works by requiring certain energy suppliers to offer 'tariffs' that pay a set rate for each kilowatt hour (kWh) of electricity you export. The amount you get varies by supplier, and you're free to shop around to get the best rates.” – Money Saving Expert
6. Geothermal Heating
Geothermal heating and cooling systems work much differently than how a traditional furnace heats. A furnace burns fuel to create heat, whereas a geothermal heat pump exchanges heat between the ground or water source and the air to heat the home. Because the temperature below ground stays constant around 50 to 60 degrees year-round, it can be used as a heat source. The fluid within the ground loop absorbs the heat from the Earth, then cycles it to the heat pump where its heat exchanger transfers the heat from the fluid to the air.
The benefit of using this system is it offers lower operating costs with homeowners saving approximately 70% a month on energy bills versus conventional heating. It’s environmentally friendly as it doesn’t consume any fossil fuels and has a highly efficient use of electricity. It also has a long life as it lasts longer than conventional equipment.
7. Build Smaller
Being efficient about the size of your home will automatically make it more eco-friendly because fewer materials will be used for the build and more efficient because less power and heat is needed. Be creative and resourceful with your design. Smaller homes have a lower impact, reduced costs and maintenance and are more efficient because their square footage and layout are more compact, practical and functional than big, traditional homes. They do require more thought and planning, but if you build them around your green lifestyle, the result will be more functional and cost-effective.
