I can’t build green can I? I’m renovating, not building a new house.

Many of our clients, who are planning to renovate, are often confused as to what they can or can’t do or should or shouldn’t do when it comes to building green.

Because most of the media and general information available is focused on informing people about new houses, we are finding people who want to renovate are left feeling that there is nothing that they can do.

“We are only renovating, not building a new house. What can we do?” is a common comment we hear from people.

In response to this, we are regularly asking clients, “if you had the choice to renovate greener or not to, which would you choose”. They always choose to renovate greener.

So what can you do and how far should you go?

Both of those questions are tied in together. In short, the answer is as far as you feel comfortable.

By making your renovation more energy or water efficient or healthier than what is standard practice, you are building greener.

Using painting as an example, a greener building choice would be to choose a low VOC paint over a standard paint. By choosing a low VOC paint you are making a decision to create a healthier indoor environment for your family.

So if you think you would like to renovate greener, here are our top ten tips to consider:

1.    Design your renovation to take best advantage of any Northern orientation, design in good cross ventilation and provide sun shading to the Eastern, Northern and Western elevations.
2.    Insulate your renovation well. Ensure you provide, as a minimum, the recommended insulation rating for your climate and location. For a natural insulation choice, why not consider wool?
3.    Install water efficient tap ware and toilets. Also, consider putting in a rainwater tank and connecting it to your toilets. Flushing of toilets uses around 10% of the water consumed in your house; this translates into around 9000-13,000 litres per year.
4.    If you have an electric hot water heater, why not replace it with a solar hot water system?
5.    Install compact fluorescent light fittings instead of standard light fittings. Compact fluorescent fittings are around 4 times more energy efficient than standard fittings.
6.    Install energy and water efficient appliances such as dishwashers and washing machines.
7.    Improve the insulating performance of your windows by installing an efficient glass such as a Low E glass. Standard glass provides absolutely no insulating value when it comes to preventing heat loss in winter or heat gain in summer. Anything you can do to improve this is a bonus.
8.    Use low VOC paints and floor finishes. Normal paints and floor finishes have high solvent content which has been proven to be bad for our health.
9.    Use low formaldehyde MDF and particle boards for your kitchen cupboards. Formaldehyde is a known carcinogen that is released from standard MDF and particle boards over time.
10.    Use sustainably sourced timber. When using timber in your renovation, look for timber that comes from sustainably managed sources with the FSC mark, not from illegally logged rainforests.

 All of the above items are very easy to include as part of the planning for your renovation. The minimal additional cost associated with them will repay itself, not just in lower running costs but you will also have a healthier and more enjoyable house to live in.

Building Green - An Overview PDF Print E-mail

Eco friendly homes are best for the planet and your health.

Having an eco-friendly house is about the way your home is designed, contructed and  operates to reduce its impact on the overall environment while creating a healthy and enjoyable environment to live in. Key green building strategies include water and energy efficiency, sourcing sustainable products and materials and using renewable energy.

The buildings we live and work in have a profound impact on the natural environment, the economy and our health. The built environment accounts for:

- 40 per cent of our total carbon emissions;
- 33 per cent of all product and material resources consumed;
- 42 per cent of our total energy consumed;
- 12 per cent of water use.

In the past, the building industry has been inherently wasteful, lagging behind other industries when it comes to sustainability. The statistics should be impetus enough for everyone involved in the building industry to accept a greater responsibility in adopting more sustainable practices.

But, for green building to succeed, it has to be mutually beneficial: there has to be something in it for consumers as well as for the environment.

And there is. The win for consumers is a more modern, healthier home with lower energy and water bills. A well-designed home can, without any change in occupant behaviour, reduce energy use by about 60 per cent and water use by about 30 per cent.

Research indicates homes that incorporate environmental initiatives now sell more quickly and command higher prices than those that don’t. The objection that building green is too costly has been overstated for far too long. Achieving the energy and water savings cited above need add no more than 5 per cent to the cost of construction.

An eco friendly home is simply a better house to live in. Studies show that indoor air quality is usually about five times worse than outdoor air due to the pollutants given off by everyday household furnishings and products. By using eco-friendly materials you create a healthier indoor environment for you and your family.

Recycled Timber Doors & Windows
Recycled Hardwood Bi-fold Folding Doors and Folding Windows

Timber bi-fold folding doors and windows offer beauty and the great open-air lifestyle that many people are looking for today. However, if you are concerned about where the wood is coming from for the doors and windows you’re considering, ask the business exactly where they source their timber from and how.

If you have thought about putting timber bi-folds into your home or commercial project but have had concerns about them, here are some answers to some common questions to help clear up a few misconceptions:

* Some people think that Timber doesn’t hold up as well as Aluminium does.
This is not true.  When timber is properly kiln dried & finished, it will hold its beauty for years to come. Recycled timber is a great choice for bi-folds because it is already seasoned, which makes for extremely stable doors and windows with no warping, cupping, expansion or shrinkage.
      
* Timber bi-folds take a lot of maintenance.
The tight grain of recycled hardwood finishes beautifully. A small amount of touch-up may be required every so often if doors or windows are in direct sun or are affected by harsh weather conditions. Aluminium doors and windows have been known to pit in areas of salt air or harsh weather. This is harder to fix.
      
* What are the insulation properties of timber?
Timber doors and windows offer better insulation than either PVC or Aluminium and are more environmentally friendly. From a thermal point of view, timber-framed windows perform extremely well. In fact, due to the excellent thermal properties of timber, timber windows rate better than aluminium in reducing winter heat loss.
      
* Using timber is bad for the environment.
Wood uses a fraction of the energy required in producing than non-natural alternatives.  Recycled wood uses zero energy in terms of its production!
      
* Timber is old-fashioned.
Recycled timbers often possess an unsurpassed beauty and pleasing character that you won’t find in any other building material. Combining the old woods with modern amenities can create attractive innovative looks. Adding recycled hardwood bi-fold folding doors or folding windows is like adding a fine piece of handcrafted furniture to a setting.

Our lifestyle is more and more about the great outdoors, both enjoying it and preserving it.

Building Biology

Why should the buildings in which we live and work be greener and healthier?
 
It is a growing worldwide belief that the increasing amount of synthetic chemicals and electromagnetic smog that our bodies are exposed to are a large contributing factor to the enormous rise in health issues for both us and the environment as a whole. However, Building Biology, practised for decades in Europe, is now becoming more prevalent in Australia and there are simple solutions to almost all of the issues.

Building Materials
 
Building materials are made cheaper every day by utilising more chemicals.
It is a simple concept. Chemicals are cheap and, the more you can substitute a chemical for something natural, the cheaper that product will be and the longer its shelf life will be.
Unfortunately, it also means that our body and planet must deal with the toxic effects.
Using natural and sustainable building materials should allow your building to "breathe" as it is regarded by Building Biologists as your third skin (your clothes being your second skin).
Careful building design and choice of building materials will cut long term power expenses as well as carbon and toxic chemical emissions.

Building With A Clear Eco-Conscience

ecobricks™ founder, Toby Sail, has always been green. Since 1991, well before recycling was commonplace and climate change the hottest topic of the day, Toby has been sourcing bricks from demolition sites, cleaning them and then reselling them.

Toby's reason for recycling bricks was simple – building and landscaping with a clear eco-conscience.

"Bricks are one of the few building materials that can be recycled and reused with minimal processing and energy consumption and look as good - if not better - than new ones," he says.

"Many people don’t know that using recycled bricks to build an average sized 25 square home compared with building with new bricks saves 7.2 tonnes of Greenhouse Gas Emissions (equal to 144,000 50 gram black balloons)."

"An average family home uses 12,000 bricks. If you build a new home using new bricks, 9.6 tonnes of greenhouse gas emissions would be produced during their manufacture. Using recycled bricks emits just 2.4 tonnes - a saving of 75%.

"By using recycled bricks, not only will you get the distinctive aesthetics and character of recycled bricks, you can be happy in the knowledge you’ve lessened your eco footprint during the building process."

Recycled bricks are also generally up to 20% cheaper than new bricks, Toby says.

Since Toby first began hand-cleaning and selling recycled bricks in 1991, over 20 million bricks have been recycled and reused in construction projects such as new homes, renovations, extensions, commercial property and landscaping.

Today, ecobricks™ diverts more than 2.5 million bricks a year (48,000 bricks per week) from landfill. This could build four houses a week.
Of these 2.5 million bricks diverted each year, around 40% are suitable for use as external feature or 'face' bricks, with around 60% used for landscaping and paving. Any brick that’s not suitable for either is made into rubble or given away as sub road base.

Toby and his business partner and wife, Marina Ward, are also busily looking for resellers in regional areas of Victoria.

"We want to be able to provide our brick cleaning equipment regionally so that the bricks from buildings being demolished can be recycled and reused in the local area. This way, locals in regional areas can use recycled bricks without having to send them to us in Melbourne for cleaning and then transporting back to them. We save on transport emissions and costs," Toby says.

Recently, Won Wron prison in Yarram was demolished and its (number) bricks recycled. The bricks have been used in many new construction projects.).

ecobricks™ also has big plans for the future - aiming to double the number of bricks diverted from landfill to 5.5 million. "If we can salvage 5.5 million bricks, it will equate to enough bricks to build 247 houses a year or 4.75 houses a week," Toby says.

Rethink recycled bricks

ecobricks™ is working with the brick industry’s peak body Think Bricks to help spread the eco-message about bricks.

"There’s an ongoing benefit to the owner of a brick home - and that is that bricks can provide thermal mass which reduces the need for artificial heating and cooling. Given that the majority of a home’s greenhouse gas emissions are caused by electricity, this means lower costs and greenhouse emissions in the long run."

Builders, Glenneagles Homes, Waltara Homes and B&G Cole, are among ecobricks™ major clients using recycled bricks for authentic period homes and as a base for rendered homes.

Glenn Eagles, a former President of the HIA and owner of premium building company Glenneagles Homes, has been building homes using recycled bricks for over six years.

"We can build a brand new home in a period style and it will look like it’s been standing there for years and years. Because the recycled bricks have already weathered for up to 100 years, the brand new home looks like it’s from the period its design is based on."

With 6.2 million bricks in stock across sites at Clayton and Sunshine, builders, architects, landscapers and DIYers will always find a brick to suit, Toby says.

"Customers come to us for three core projects - building new homes, finding bricks to match an existing home for a renovation or extension or landscaping."

ecobricks™’ range of recycled bricks suitable for facework includes Rustic Reds, Coachhouse Greys, Clinkers, handmade bricks dating back from the late 1800s and the rare Hawthorn Black and Browns.

Toby is quick to point out that modern homes can also be built using recycled bricks - either for face work or rendered finishes.
Builder, Glenn Eagles, uses recycled ‘builders bricks’ for rendering and hidden structural walls.

"They are much cheaper than the distinctive 'face' bricks and provide a far superior base to concrete bricks for rendering because they have little or no expansion and contraction leaving a beautiful, crack-free finish."

Commercial property developers are also wise to recycled bricks and ecobricks™ has recently supplied bricks for major commercial construction and refurbishment projects including the Tribeca Apartments in East Melbourne, Commonwealth Village in Parkville, Melbourne University campus and Deakin University in Burwood.


Building with recycled bricks compared with building with new bricks:


- Uses 86% less energy

- Produces 99% less SO²

- Produces 43% less CO²

- Produces 98% less NO²
