When it comes to the green home, ratings matter. There are a number of eco certification for home based appliances and white goods. Plus you can get your home professionally assessed for energy efficiency.

Residential homes can be given a rating based on the National House Energy Rating (NatHERS) which is an index of the home’s thermal performance. It is done through a professional analysis by a qualified assessor working in conjunction with the builder of the home. NatHERS provides a baseline for assessment software to rate a home’s energy efficiency potential. Most homes in Australia currently fall below a 5 star rating, but the current tool has now been adapted to allow for a potential 10 star rating (which would be equivalent to zero conditioning energy). This system is based purely on the home’s infrastructure and does not include appliances or hot water systems. Find out more about energy ratings for your home.

Good insulation is a key feature in any energy efficient home. And homeowners are keen to take advantage of Kevin Rudd’s important announcement last week, with funds for ceiling insulation becoming available from the federal government. The Federal Government will be providing eligible homes wiht free ceiling insulation worth $1600. Landlords and renters can benefit too with rental properties being included in the package.

Yet with all the available insulation out there, which one should we consider?

Eco Home Tip #16 – Ask about the R value – the measure for insulation materials is the R value. A high R value means better insulation potential. For example, Pink Batts offers a range ceiling insulation products that have an R value of up to 6.0.

Eco Home Tip #17 – Natural insulation – Take your insulation innovation even further and look for ceiling insulation made from sustainable materials, such as Goldenfleece wool insulation. All natural wool fibre has great insulating properties, with the CSIRO claiming, “wool insulation performs better because of it’s ability to rapidly absorb and desorb moisture from the air.” And you’ll be helping out the rural farmers!

Eco Home Tip #18 – DIY insulation – there are lots of simple insulating ideas homeowners can adapt to protect their homes against the elements. Seal draughts with door snakes or hang some thick curtains on your windows to keep out the coming cold.

Insulation is the first step to a great energy efficient home that will save you money. Well designed homes that incorporate insulation, thermal mass design and sustainable energy alternatives, such as solar panels, can save some homeowners up to 50% on their annual energy consumption. Plus you get to enjoy the comfort of having a pleasant living environment year round.

There are as many definitions of  “green” as there are shades of color. Wikipedia defines a green building, also known as a sustainable building as “ a structure that is designed, built, renovated, operated, or reused in an ecological and resource-efficient manner.”

Dade County Florida’s Website reads that, “Sustainable building practices go beyond energy and water conservation to incorporate environmentally sensitive site planning, resource efficient building materials and superior indoor environmental quality.” The website lists five key benefits of sustainable construction that seems to concisely capture the “spirit” of the green building concept.

- Lower electric and water utility costs

- Environmentally effective use of building materials

- Enhanced health and productivity

- Long-term economic returns

- Reduced environmental impact

The need to reduce costs associated with energy production and  importing building materials,  the importance of conserving water and natural resources and minimizing environmental impact are challenges that are even more paramount within our island communities. Green  initiatives provide excellent benefits but carry a pricetag asociated with implementation. We’ve looked at the benefits and the challenges, but what are the affordable solutions?

Lower Eletric and Water Utility costs

Thin-film solar and Atmospheric Water Generation are two affordable technolgies that fit expectioannly well in the Caribbean region. With the abundance of sunshine we receive intermingled with overcast days, it is still estimated that a solar radiation of 4-5 hours per day is typical for the region. Using lighweight thin-film solar, with a capacity of an estimated 5 watts/sq ft. a typical 1,200 sq ft home could easily support a roof laminted 3,000 Watt solar power system. A system of this size would generate an estimated 12-15kWh per day.  By reducing electiical lighintg, cooling, and appliance loads to less than 4k the solar system can also be recued in size.

How do we reduce our electrical load calculations? Design and retrofit with L.E.D. Lighting,  A typical home using high efficiency L.E.D. lighting would use just under 250 Watts for the entire lighting circuit and provide equal or higher lumen output than convenienal incandescent or CFL lighting systems. Heat pump water heating technologies provide an estimates 7,000 btu output and a max water temp of 135 while using less than 800 watts nominal. Air Conditioning units using proven ductless-split DC Inverter technologies provide remote controlled zoned cooling while using as little as 1,200 watts for a 11,000btu system. Energy efficient appliances are readily available and help to reduce overall electrical loads

A very natural solution for clean water production in the Caribbean has been around since the beginning of time. Atmospheric Water Generation (AWG) systems use the natural humidity in the air to produce up to 6gallons per day of pure filtered drinking water without the need for any plumbing or realated  infrastructure. Dispensing 99.9% pure water, the AWG system can be operated directly from solar power or plugs into a standard household outlet.  With a built in water heating element the units dispense hot or cold water on demand without the need for maintaining an inventory of bottled water. Production costs are estimated between $0.06 -0.14 per gallon of water.

Environmentally Effective use of Building Materials

What’s needed is a building system that can resist high winds, is versatile, structural, provides a high level of insulation, minimim waste and is affordable. Concrete Structural Insulated Panels (CSIP) provide an excellent alternative to conventional concrete block construction in the Caribbean. Proven and accepted throughout the United States, CSIP’s are pre-designed, pre-cut, professionally engineered, insulated, provide a strucural frame and exterior and interior concrete fire resistant surfaces for finishing. These lighweight concrete panels are produced by manufacturers that are members of the Unites States Green Building Council (USGBC) such as T.Clear Corp of Hamilton  Ohio. Their ProTec® CSIP building system  provides less skilled labor, reduces wall construction time to a matter days verses months and is competitively afforadble when compared to block or conventioanl construction techniques. The company literature states the panels are “framing, sheathing, insulation and interior wall surface all in one. This equates to building more homes in les time with fewer associated costs and waste.

Enhanced Health and Productivity

Clean water, fresh air, low VOC and no off-gasing products should be the benchmark for homes built under the “green” design concept. Energy conservation and eco-friendly homes do not happen by accident, it takes planning and design guidelines to ensure homes provide comfort, style and are also affordable. Choosing off the shelf products that are eco-friendly minimize costs and help descrease the time required to source specialized products that add time and expense to the construction process. Despite the misconception, “green homes” can be stylish, affordable and built on a reduced timeline.

The Protec® Building System is currently used by HDC Development Corp  within the Bahamas to build as it describes, “Net Zero Energy Homes”. Recently receing apporavel from The Bahamas Ministry of Works, the Protec Building System®  is meticuoslesy engineered to design loads of up to 150 mile per winds. According to the information from the company’s website, these “Net Zero Energy Homes” gerernate more energy than they consume, have minimal environmental impact, resist high winds and are very compatiable to developers seeking higher construction productivity rates.

Long-term Economic Returns

Unfortunately, when green initiatives are initially introduced into some regions for the first time, typically there exists an entense amount of resistance  as traditional stakeholders, with  entrenched concepts and methods are challenged by the new technology. However, for the greater good of the entire Caribbean  region, traditional beauracratis “red tape” needs to be pierced so that a new generation may benefit from the advances in proven  technology and ensure our regions continued success in the renewable energy amd sustainable development sectors.

Openminded acceptance of proven “green technologies” will bring investment, trainig, jobs and prosperity to the Caribbean region. The region is ideal to capture the full potential of clean solar and wind power generation. Long-term economic growth is the fruit that’s harvested when we plant the seeds of green initiavtes today.

Reduced environmental impact

Waste reduction, resource conservation and matinainting pure water inventories are important issues that face any region, but even more so here in the Caribbean islands. As our population grow so does the need to pay more strict attention to the subject of  waste management and recycling. Education and acceptance of recycling is the key. Conservation is an adopted lifestyle and the population must see it as a benefit in order to embrace it. Tangible incentives such as reductions in Waste Collection rates for househgolds that recycle, reduced utility rates for homes with  Solar  or wind Power Generation systems and reduced municipal water rates for households with Atmospheric Water Generators would go a long way to helping the large public adopt and embrace “going green”. 

Lets hope the islands of the Caribbean region can by careful and wise use of our startegic natural  resources become the worldwide leader in the adoption and implemntation of proven green technologies. It is clear we have the most to gain and success will equate to increased toursim, investment, training, jobs and prosperity for our region.

Looking to buy or rent a green home? These days, lots of green homes are going on the market as sellers and landlords recognise they’re in demand. But how is one to know which homes are truly green?

Here’s a checklist of features to look out for and questions to ask to determine the green quality of your next home.

Eco Home Tip #7 Location Location Location – pick a location that’s convenient and easy to get to. Close to shops, amenities and public transport will reduce the amount of emissions that come from getting around. Inquire about the council’s recycling program.

Eco Home Tip #8 Orient yourself with the right orientation – if a house is to have good eco principles, it will designed with the right orientation. This means that the living areas will face due north, to make the most of the winter sun while allowing the hotter summer sun to pass overhead. Sleeping rooms, meanwhile, will be oriented towards to the South to capture cool summer breezes.

Eco Home tip #9 Cosy is not a four letter word – consider how the space is used as much as the size of it. Oversized houses utilises more resources in both construction and maintenance, while smaller dwellings are cleverly conceived can feel quite spacious.

Eco Home Tip #10 Inquire about insulation – ask about the insulation. Higher R values means the house will better protected against extreme weather elements. See if the windows are double glazed. While you’re at it, ask about other green home features such as solar panels and solar hot water. Make your message loud and clear!

Eco Home Tip #11 Good green help – there are a few Australian green realtors, such as ecoproperty, who specialise in green listings. Check the Green Pages green directory for real estate agents who will help you find the perfect green home.

The important thing is to ask before you buy. Even if the real estate agent can’t tell you upfront, it’s important to let the market know that buyers and renters are looking for this bit of information. While no single home will have all of the sustainable features listed, at least you can get a clear picture of what the potential home has to offer.

Autumn is approaching and that means colder days ahead. However, Australia is blessed with an amazingly moderate climate where even our chilliest days are nothing compared to other regions in the world. This means that Australian residents can take advantage of all natural low emissions heating in their green home.

As well as insulation and energy efficiency, there are other innovative heating ideas to keep your home toasty warm for the winter.

Eco Home Tip #31 – Seal up draughts – Put snakes under door jambs, get weather stripping for your windows. Heavy curtains also help keep in the heat and keep out the cold. You’ll be amazed at how cosy a room can be without any heating at all.

Eco Home Tip #32 – Look beneath your feet – the soil beneath you home acts as a natural insulator, keeping the ground warm all year round. By employing a geothermal heat pump, your home can be take advantage of this natural heat during the colder months. In a geothermal system, liquid is circulated in pupes that run beneath your home. As the liquid gets warmer, it is pumped up to a heat condensor where the heat is released into your central heating system.

Eco Home Tip #33 – Keep it low – Switch your thermostat down a single degree. When we come in from the cold, we’re very likely to crank the termostat up much higher than necessary. Remember that every degree lower on your thermostat can potentially save up to 10 per cent on your heating. Throw on a jumper instead.

Eco Home Tip #34 – Cut your system down to size – as with air conditioning, don’t go overboard with your heating. You’ll be amazed at what a single space heater will do.

Eco Home Tip #35 – Look for the Energy Star – As with all appliances, energy star ratings give a good indication of the energy efficiency of the appliance. Energy star rates furnaces, boilers and heat pumps for central heating in your home.

Setting up a good green home starts with energy efficiency. Traditional incandescent light globes lose almost 90 per cent of their energy in generating heat – only 10 per cent of the electricity used is actually going into lighting your room. And because of their various filaments and parts, incandescent bulbs generally have a much shorter life span than their more energy efficient counter parts.

Installing energy efficient globes is one of the most cost effective and easiest options available for a good green home. Some companies had even traditionally given out energy and water saving “packs” for people to try out. Nowadays, these energy saving globes are available everywhere – so the question becomes, which light fitting is right for you?

Eco Home Tip # 36 – The lowdown on CFL – Compact Fluorescent (CFLs) are the most common energy saving fitting. CFLs use just about 20 percent of the energy required for the same amount of light from an incandescent globe and last 10 times as as long. All in all, a CFL will help reduce the cost of lighting your home by as much as 60 %.



Eco Home Tip # 37 – Keep your CFLs close, if shaded – a British study last year revealed that CFLs produced a small amount of UV radiation when used unshaded and in close proximity. Open globes were of note, which “encapsulated” globes were considered safe. So if you’re using a work lamp with a CFL, keep it shaded of opt for an encapsulated globe instead.

Eco Home Tip # 38 – Recycling your CFLs – The typical CFL contains a minute 4 mg of mercury sealed in its glass tubing. Some manufacturers have lowered its CFL mercury content to as little as 1 – 2.5 mg. Handle your CFLs with care and take advantage of recycling programs for CFLs to keep mercury from ending up in landfill.

Eco Home Tip # 39 – Leading by example with LEDs – Light emitting diodes (LEDs) are another popular energy efficient lighting option, especially to replace halogen globes and downlights in your home. The small cluster of diodes can be arranged in a number of configurations and sizes to suit your home. LEDs have been traditionally found in electronics including clocks, and have a variety of uses in terms of producing a broad spectrum of bright coloured light. LEDs are the perfect substitute to the more heat intensive halogen globes and last for over 50,000 – 60,000 hours and uses 70 percent less energy than standard halogen globes. LEDs are also mercury free.

Lighting a home can account for as much as 20 percent of a home’s energy use. Energy saving lights are simply a bright idea for your green home.
