Building Green? Here's some tips.

Building Green? Here's some tips.




In South Africa we have had 2 years of unusually warm weather and a drought.  The coal reserves are set to run out by 2020.  It is now vitally important to be environmentally aware and active.  

According to the Zero Energy Project, the construction and operation of buildings accounts for 40% of all energy used in the USA.  Fortunately more and more building professionals have noted the harmful effects and have developed strategies for creating greener buildings.

In order to have a green home you need to cut costs when needed.  This means using less electricity and trying to eliminate products that have a negative impact on the environment. Often many cost-effective ways of going green are forgotten.


 Here are some of the top reasons why you should choose to go green in your household for the sake of your budget.

1. You eliminate the stress that comes when you pay high utility bills every month.

2. You can use the money saved for holidays or special occasions.

3. You will reduce your carbon footprint.

4. You will be living in a much healthier environment.

The first step is to hire a green contractor to build your house.  Be careful to check their credentials, many people are 'au fait' with green building jargon, but are not qualified to build a sustainable, energy efficient house.

There are certain elements and home features that contractors use to construct eco-friendly homes. Here are some excellent home building ideas to consider:

1. Location, Location, Location :  When choosing a plot or buying a property take note of the house / plot orientation - avoid building/buying a West facing home.  I've lived in West facing house and even in the winter it got unbearably hot.  Avoid building a house in an environmentally sensitive area such as earthquake or hurricane prone areas or near a flood plain.  Check if public transport is easily available and that schools and local shops are not far away.  This means that you will not need to drive everywhere and travel time will be reduced.

2. Size Matters : A small house built with eco-friendly techniques is going to have a much lower environmental impact than a large home.  A big house is going to cost a lot more to heat and cool.

3. Insulation :  Insulation is the most important factor to consider when building a green home.  Heating and Cooling account for about 50% of your home's energy bills.  40% of all heat lost is through your homes walls, so it's worth looking at building cavity walls (if you are building with brick) or installing insulation under plaster boards.  Be careful about air leaks around windows, doors and ducts - air leaks are responsible for a lot of heat loss.  Properly installed insulation will not only reduce your energy consumption, but will reduce your electricity bills substantially.

4. Choose Sustainable Materials : Some materials have a much lower impact on the environment than others based on such aspects as how they’re harvested, their amenability to recycling or decomposition in landfills. 

Some of the top sustainable building materials include :

· Bamboo, Linoleum or cork flooring

· Wool bricks

· Solar tiles

· Paper or cellulose insulation

&  Triple-glazed windows

5. Choose Materials & Appliances that Boost Efficiency : It's vital to keep an eye on the environmental impact of your house after it's been built. Many Appliances and materials will make your home more energy efficient.  They include :

· Programmable thermostats, which significantly reduce heating and cooling consumption

· A high-efficiency, Energy Star-rated HVAC system

· Energy Star-labeled appliances and fixtures

6. Reduce, Reuse, Recycle:  Try and reuse old material such as windows, wood floors and doors in your new home.  Recycled materials like glass, aluminium, recycled tiles, reclaimed timber and recycled plastic can be used in Green Building.  It's also worth checking out Architectural / Building Salvage yards.  You can often get great bargains and contribute to saving the planet at the same time!

7. Install Solar Panels:  Solar Energy is a clean and renewable source of energy.  Solar Panels may be expensive at first, but the long-term savings you will make are an amazing example of the benefits of going black to green.

8. Rainwater Harvesting Systems and Tankless Water Heaters:  It's worth installing a rainwater harvesting system.  The water can be used for flushing toilets, washing your car and watering your garden.

With tankless water heaters you don't have to wait for your geyser to heat the water you need. Tankless water heaters only use the water that is required - it passes through an electric coil. This means that excess energy costs are eliminated as you don't have to keep a tank of water constantly hot and you get more attic space from eliminating your geyser.

10. Water Conserving Fixtures: Low flow taps, toilets and shower heads are a few of the ways you can cut your water consumption.  Also buy washing machines and dishwashers that are water and energy efficient.  It's also worth looking at installing a grey-water recycling system. The Grey Water can be used to flush toilets and for irrigation.

11. Eco-Friendly Lighting:  Both LED and CFL Lights cost more initially, but use considerably less energy and last a lot longer than the traditional incandescent light bulbs.

12. Efficient Landscaping: Shady landscaping can protect your home from direct sunlight during the summer.  Planting trees on the Northern (Southern in the Northern Hemisphere) and Western side of your home will keep your house cooler.  In the Winter when trees shed their leaves they will allow more sunlight to reach your home.

And finally : 

How to Become Greener in your Household :

Some people think that going green is going to be difficult and expensive.  However there are some very simple ways of saving energy such as :

Turn off any lights and appliances when you don't use them.

Remember to unplug appliances or switch them off at the wall.  Leaving appliances such as TVs and Computers in hibernation mode will eat energy.  Also make sure that you do not leave your cell phone charger plugged in when you have finished with it. 

Only buy recyclable containers and re use plastic containers for food storage.

Initially building a green home can be more expensive, however in the long term it will save you a lot of money.  In addition there are many health benefits to living in a green home, you will sleep better and cognitive performance is greatly enhanced.  By creating a green home you will be passing on the importance of environmental issues to your children and the rest of your family.

Preston \ud83d\udc1d Vander Ven - even small changes like not leaving your T.V. etc. on standby can make a huge difference. My Dad once told me that leaving devices on standby and phone chargers plugged in all the time can add at least 15% to your energy bill a month!

Hi Lisa \ud83d\udc1d Gallagher - these aren't my photos - I will post some soon, they are taken with a small digital camera - I was using film up until I couldn't get it anymore.... I am saving up for a 'back' that will fit on my long lens. I get most of my images that I use in my posts from Free As far as A/C is concerned I used to live in Singapore with my parents when I was a teenager. We lived in an old colonial house with deep eaves, very high ceilings and a really v. good cross flow of air. The Lounge was open on three sides. The living rooms were also quite large. However it was a different story at night - the bedrooms were small and only had one window, so we couldn't just rely on a ceiling fan. The trouble is that most houses today are not designed that way and get uncomfortably hot in the summer months. All I can suggest is that you get good insulation in your roof....

Thanks Devesh Bhatt - v. pleased you enjoyed my article. It makes commercial sense to build green and in many cases now it costs the same (or can be even cheaper) to construct an environmentally friendly building. There are many health benefits for the people living & working in green buildings - check out

Thanks ! Glad you enjoyed the article. There have been studies recently that demonstrate that there are many benefits to a green building, apart from the energy saving aspect, "Studies into 69,000 buildings − homes, offices and factories − in 150 countries show that there are fewer illnesses among residents and workers, who report they are more comfortable and happier. Employers also find they are more productive. Companies that opt for “green” buildings gain because workers stay longer in their jobs and have fewer absences, while recruitment is easier because new employees are attracted to environmentally-friendly buildings."
