I GAVE up counting downlights when I reached 55 - and that was just upstairs. I was touring the Monarch, Metricon's ''five-star'' display home, and I felt almost queenly as I surveyed five bedrooms, each with en suite.

The Monarch looms over a suburban block like a tall, dark sentinel. It's a long, brown, two-storey house that feels like a Balinese holiday resort inside. Cream-coloured floors sweep you past the guest room and home theatre to the massive kitchen/family/dining zone and ''outdoor room''. The bedrooms are large and luxurious. So are the bathrooms.

As I examined the ovens (two), the laundry (bigger than my one bathroom) and the walk-in wine cellar, I half-listened to a marketing spiel that seemed to emanate from one of the giant TVs dotted around the place. ''Huge laundry!'' I heard. ''Huge wrap-around outdoor entertainment room!'' Almost everything here was huge - except for the skimpy garden.

Australians have always admired big things: we're a ''big country''; BHP was the ''Big Australian''. Now we're getting bigger - and so are our houses. In Victoria, new house sizes grew by 16.3 per cent over the decade to 2009, compared with an Australian average increase of 9 per cent. The average Victorian new house is now 252 square metres.

With a floor area of 456 square metres, the Monarch is all about rewarding yourself with excess. When I first read of it, I glibly assumed it was in a newly built fringe suburb, where the lack of public transport and amenities might give you a reason to stay indoors and bathroom hop. But it's in Balwyn, in Melbourne's wealthy inner-east. Lots of upmarket McMansions are being built in old established suburbs, too.

Even if you're appalled by a house with such royal dimensions, it's hard not to be embroiled in the culture of Big. Consumer capitalism is built around the idea of frequent upgrades. The average TV screen is now more than a metre wide. Fridges and stove-tops are also expanding - even as we're cooking less.

And super-sizing happens by stealth. I recently ordered a regular coffee at an airport cafe, assuming it was a standard cup size. But what I saw as standard was now ''small''. Their ''regular'' was my idea of large and their ''large'' was the size of a milk-shake.

The same marketing principle probably helped shape the Monarch's proportions. No one needs five bathrooms. Imagine cleaning them. But after touring the Monarch, a three-bathroom home might begin to seem normal. This week, Victorian Building Commissioner Tony Arnel expressed his concern that consumers were being ''up-sold to home theatres, additional bathrooms and media rooms'' as a marketing tool.

Intriguingly, this culture of super-sizing coexists with another trend: the rise of connoisseurship and the shrinking of our electronic gadgets. So on the one hand you can get a towering latte at Gloria Jean's; on the other, you can buy a double ristretto made with house beans at a trendy cafe. And when not watching a giant plasma TV, you might be peering at a tiny screen on a phone. Small and boutique is a way of contrasting yourself with Big.

Of course, value for money is Big's chief selling point. A Subway ''$7 Foot Long'' sandwich? Bargain. But Big has hidden costs. Hungry Jack's hefty Ultimate Double Angus burger, for instance, will reward you with 3532 extra kilojoules.

Bigger houses generally have a bigger carbon footprint and cost more to run. I spotted eight solar panels on the Monarch's roof - but how much power would its galaxy of downlights churn through? How much water would be wasted in those bathrooms? And when a house devours its backyard, the environment suffers.

Vegetation around homes absorbs rainwater, helps cool the building and contributes to local biodiversity, says Professor Tony Hall, author of The Life and Death of the Australian Backyard. But people no longer see gardens as important. ''What's important is the size of the house,'' he told me. It's not that block sizes are getting smaller, he points out. ''It's the houses getting bigger.''

Planning laws have enabled this shift, but lifestyles are changing, too. People are working longer hours to service big debts, and children have little time for free play. Houses are seen as ''an investment'', Hall says, and people are being told that they need a home theatre or a certain number of bathrooms to protect that investment. Australians now have the biggest houses in the world.

In the predictably huge brochure I collected at the Monarch, I read that the house had been designed ''with deliberate, thoughtful intent to create seamless lifestyle areas, exuding global sophistication''. I reckon Australia's love affair with Big has more to do with our isolation than global sophistication.

Though the internet has partly bridged the tyranny of distance, we're still a really long way from Tokyo or Amsterdam or London, so we don't often see the everyday spaces in which people of other nations live.

Mostly, we just see our friends and neighbours' houses (plus those in Hollywood movies) and it's hard not to compare yourself with them. In the Netherlands, the average new house size is 115 square metres. In Britain, it's just 76.

Thermal Energy rating

How do you rate it? Australia’s green building rating tools

How do you rate it? Australia’s green building rating tools

EcoGeneration — May/June 2011

A number of rating schemes have been developed in Australia to assess the energy consumption and environmental impact of commercial and residential buildings. Sustainable Built Environment’s Chris Begert looks at three of the better known rating tools: Green Star, NABERS and NatHERS.

While Green Star, the National Australian Built Environment Rating System (NABERS) and Nationwide House Energy Rating Scheme (NatHERS) have different origins, and were designed with different uses in mind, there is an increasing convergence in their application.

Green Star

The Green Building Council of Australia (GBCA) developed the Green Star office rating tool in 2002. Today, there is a wide range of tools available for different types of buildings, such as educational facilities and multi-residential developments. Energy efficiency is a strong focus of the tools but it also addresses management, innovation, indoor environment quality, water, materials, emissions, transport, land use and ecology.

A Green Star assessment is comprehensive, and is designed to recognise national and international best practice and leadership. To achieve a star rating usually requires a significant investment in design and capital cost.

Article continues below…

All Green Star tools are voluntary assessments and can be obtained as a design or as-built rating. Given that a formal certification requires at least four stars, an official rating places a building amongst the top 25 per cent of the market in terms of environmental impact.

NatHERS

At the other end of the spectrum to Green Star, the NatHERS tool is used to assess house designs against minimum compliance standards set by the Building Code of Australia (BCA). This framework is used by the more familiar names of First Rate, BERS or ACCURATE.

A NatHERS assessment measures the thermal performance of the envelope of the building, taking into consideration some aspects of location, orientation, shading and overshadowing as well as building fabric and glazing. The result is a relative estimate of heating and cooling demand.

The 2009 version of the BCA requires an individual dwelling to achieve a rating of 5 stars in Victoria. In 2010, this threshold was raised to 6 stars or equivalent.

National Australian Built Environment Rating System (NABERS)

While Green Star and NatHERS predict building performance, the NABERS tool assesses real performance. Energy is assessed by reviewing actual energy bills, indoor environment quality with on site measurements, water consumption from bills and waste generation by quantifying outputs.

With the introduction of the Commercial Buildings Disclosure schemeimplemented on the 1 November 2010, offices with a floor area greater than 2,000 square metres will be required to disclose their energy performance with a NABERS rating when the space is being leased or sold.

As part of the NABERS energy scheme, design assessment protocols have been developed. These protocols predict the future rating of developments through thermal computer simulation and are aiming to assist design teams in providing a building that, later on, will achieve the desired performance. While a successful computer simulation cannot guarantee that the building will achieve its target in the future, and no formal certification can be obtained just through simulation, the protocols are an important part of designers’ toolkits that help evaluate different scenarios.

The protocols also form the basis for the energy assessment within the Green Star tools. Even though Green Star and NABERS have different base case benchmarks, the protocols are used in Green Star to determine the energy performance and the resulting points achieved.

The outlook

As environmental awareness in the community grows, environmental performance assessment tools are being used to set quantifiable targets for building design and operation. Rather than prescribing fairly inflexible and thus untargeted deemed-to-satisfy provisions, the tools allow designers to innovate, create their own solutions and evaluate them using the methodologies and benchmarks of third party tools.

With energy efficiency being one of the most salient aspects of modern building design, the scheme will move NABERS Energy ratings increasingly into the industry spotlight. Comprehensive Green Building tools such as Green Star will ensure that the required optimisation of the way we use energy within our buildings is balanced with other important design aspects of the built environment.

Carbon Who?

To certify or not to certify?

Carbon Down

switchWe all know what the 'Australian made' certification looks like and what it stands for. But what about sustainable certifications, for example how do you really know if a product is genuinely organic? Certifications are easy identification marks but often it's hard to know which ones to look out for and what they stand for.

As in most industries, sustainability has regulatory bodies and industry watchdogs that keep standards high and keep consumerism fair. Such bodies are, the Australian Competition and Consumer Commission (ACCC), Standards Australia and International Standards Organisation (ISO).

There are also many consumer advocate groups that investigate environmental claims and bring green labelling and reporting standards up to scratch, such as Choice Green Watch. Explained below are some of the more widely used and reliable sustainable certifications that will help you make better environmental purchasing decisions, at home and for your business.

Fairtrade www.fairtrade.net
Fair Trade Certification ensures that products have been produced and sold fairly. This ensures that producers, workers, and communities who are generally disadvantaged in the international market are paid fairly.

Australian First

Australian first: Commercial building trigeneration precinct for Sydney

Investa and Origin

investaTwo players in Australia's corporate landscape switched on a brand new system to generate lower-emissions electricity at Coca-Cola Place in North Sydney and share its benefits with Deutsche Bank Place across the harbour.

In a first for Australia, the NSW Minister for Resources and Energy, Hon Chris Hartcher, MP, officially launched the trigeneration precinct for these two commercial buildings.

Investa Property Group ("Investa") and Origin have set a precedent for smarter energy management in our cities with a compelling, alternate energy solution that helps lower emissions and network demand, while increasing energy efficiency and power security.

Coca Cola Place and Deutsche Bank Place are significantly shrinking their carbon footprints, saving around 1,000 tonnes of carbon dioxide per year between the two buildings.

Origin Executive General Manager, Energy Markets, Frank Calabria said, "Working in partnership with our customers, by deploying smart technology and highly-efficient systems, we can unlock the promise of trigeneration systems in a manner that can cut carbon pollution at the same time as delivering economic benefits. This solution with Investa is a great example of how we are paving the way for more intelligent energy systems of the future."

This trigeneration solution uses natural gas to produce electricity on-site, as well as heating and cooling for the building. As the waste heat is captured to provide heating and cooling, trigeneration provides up to 80 per cent efficiency, a significant increase on conventional coal-fired power stations which convert only 30-40 per cent of their fuel energy into electricity. [1]

This energy milestone overcomes challenges that have been limiting the use of trigeneration technology at large commercial sites in the past.

Chairman and CEO of Investa, Scott MacDonald commented: "As an owner and manager of more than 60 commercial office buildings we aim for maximum efficiency - that means keeping energy bills low, while providing premium services to tenants."

"With this initiative we are leasing space to an operator which can generate power, as well as manage the balance of demand and supply."

Two Energy Service Agreements (ESA) allow Investa to purchase electricity, hot water and chilled water from Origin's distributed generation company, Cogent, as well as top-up, peak and off-peak electricity for both sites.

"This is Australia's first open commercial tri-generation precinct, delivering a more efficient way to generate power, heat and cooling at the source," said Sydney Lord Mayor Clover Moore MP.

"It is the first step to building a trigeneration energy network for the city centre that will reduce carbon pollution and increase efficiency, for city businesses," said the Lord Mayor.

With Origin's cogentpower, a 'virtual private energy network' is overlaid with the Ausgrid network to balance energy demand between the two buildings. This solution will enable the trigeneration plant at Coca Cola Place to operate at maximum efficiency all year round, while taking advantage of Sydney's mild climate.

It is the first step towards creating precinct-based trigeneration systems for buildings within the same distribution network as surplus, lower-carbon electricity can be exported to the electricity grid. As this electricity is generated in North Sydney's CBD and shared into the grid locally, energy is not lost via the high-voltage transmission network.

It is estimated that 12 separate entities control around 60 per cent of office accommodation in the City of Sydney, so the uptake of commercially-viable green technologies can make a real impact on emissions for this sector.

"Responsible building operators strive to use as little energy as possible," said Craig Roussac, General Manager of Sustainability, Safety and Environment at Investa.

"This agreement proves we can have our cake and eat it too. We can power a super-efficient building with lower emissions electricity, while at the same time heating and cooling it with the waste heat that would normally go up a coal-fired power station's smoke stack. In addition, further benefits flow from the ability to export excess electricity to the grid," Mr Roussac said.

"This partnership tackles the supply of energy, opening the door for precinct-based trigeneration systems that will underpin more efficient buildings and more reliable infrastructure." Mr Roussac said.

Commenting on the initiative Genia McCaffery, Mayor of North Sydney Council said: "Coca Cola Place has a set a benchmark for sustainability and design in the North Sydney CBD. With this trigeneration project, Investa and Origin have raised the bar once again, showing commercial property owners across Australia just what is possible in generating and using energy efficiently."

These Boots were made for walkin

Richard Maino

A brilliant idea to develop pavement tiles that create electricity from footsteps now celebrates a contract for a vast shopping centre on the site of the London 2012 Olympic & Paralympic Games.

Go for a walk and help power your town or city. That could happen soon on the streets, according to a UK inventor who says a paving stone in a busy area is stepped on by more than 50,000 pedestrians every day.

To harness that power, young graduate Laurence Kemball-Cook came up with the idea of the energy-harvesting floor tile he calls Pavegen.

It is the first device of its kind to capture this energy and transform it into electricity. When fitted in heavily pedestrianised areas it can power street lights and bus shelters, providing localised energy independence.

Pavegen is celebrating a contract for the massive Westfield shopping centre on the site of the London 2012 Olympic Games & Paralympic Games as well as its first permanent installation in a school walkway. Some seven million people are expected to walk through Westfield in the two weeks of the 2012 Games and all of them will step on Pavegen tiles.

The tiles are made of 100 per cent recycled rubber from old tyres. Every time someone steps on one, it flexes a dynamo technology that stores the kinetic energy produced. The tile glows to show pedestrians they are creating power.

The footfall energy could power street lighting, information signage and other applications that spring into life when people approach them.

The tiles can be used almost anywhere. Pupils at a boys' school in Canterbury, southern England, are now lighting up a corridor simply by walking through it. And the Pavegen tiles will also help the Olympic site's Westfield shopping centre to meet its stringent targets for environmental sustainability, making it one of the greenest shopping arenas.

Laurence Kemball-Cook, a Loughborough University graduate set up a company in 2009 (http://www.pavegen.co.uk/). The product has won awards from the UK's Technology Strategy Board and the Chartered Institute of Builders and has been described by UK Science Minister David Willetts as a "great example of British innovation".

Pavegen has been showcased at London's Science Museum in the Atmosphere Gallery opened in December.

One of the country's leading universities, Loughborough, supported the Pavegen technology in its infancy through its student business plan competition and Kemball-Cook was presented with a graduate enterprise award in 2010.

The device won first place in the Innovation Future Zone competition at Ecobuild 2010, the world's biggest event for sustainable design, construction and the built environment.

Loughborough's pro vice-chancellor for enterprise, Professor Phill Dickens, said: "Pavegen is an excellent example of how our enterprising students can apply their skills to address crucial issues like sustainability. I am delighted to see the company achieve such significant success in just over a year."

Flexing just five millimetres, the Pavegen slabs absorb the kinetic energy produced by every footstep, creating 4-10 watts of electricity. The energy is stored in the slabs in a battery for up to three days or distributed to nearby street lights, information displays and even electrical appliances such as computers and fridges.

The energy generated from five slabs can illuminate a bus-stop throughout the night and, with heavy use, a Pavegen installation could pay for itself within two years, with each slab targeted to have a five-year lifespan. The technology is suitable for indoor use and Pavegen is finalising the design for the outdoor units.

Only five per cent of the footfall energy goes to the low-energy LED lamp to make the tile glow, while the remaining 95 per cent powers the tile's environs.

Constructed from marine grade stainless steel and recycled materials, the rubber surface is available in various colours and the internal components are made from recycled aluminium.

* Each slab generates 2.1 watt per hour when located in an area with high footfall - based on a hit rate of a footstep every 4-10 seconds.

* Testing at trial sites has shown that five hours of walking at peak time will generate enough power to illuminate a bus stop for 12 hours or more.

* Energy is stored within lithium polymer batteries, depending on functionality of system.

After the latest installation in the Olympic shopping centre, Kemball-Cook dreams of going global. He said: "I can imagine Pavegen in more remote areas of India, for instance," he said. "There's huge footfall there, but where there is power it's polluting, fossil-fuel energy. This could be transformative."

Here's an idea

Builders get paid for energy efficiency
