The greenest homes in NZ

There is simply no other kitset or building company that is as lean or green as QBH.

Insulation. Our homes are insulated to R3.9 - Floor, Walls and Roof. And it is a genuine insulation value as it is factory produced. Overall the entire  building envelope, it's about double the insulation standard for North Island NZ.

Our homes are double glazed - as standard.

Energy efficient LED light bulbs are standard in all our homes.

We don't use treated timber as the off-cuts can't be recycled. The same with plasterboard and fibreglass insulation. 

Solar power generation - we have 10kw of photovoltaic solar cells on one of our factories. 

Lean Manufacturing. We use lean manufacturing which minimises waste - because the client ends up paying for everything that goes to landfill. So if we have minimal waste to landfill, the cutomer gains, with lower costs.

Lean Design. We highly optimise our designs so that there is little wasteage. By putting effort into the design, we  can make sure that most of our off cuts are used in other parts of the build. This is one reason why we don't change the design, because they are so highly optimised for factory mass production.

Lean delivery - Generally, only one delivery / kitset (95sqm house comes flat packed in one 40' shipping container. Plus one concrete delivery.

Lean Assembly.  Our homes are about as pre-finished as they can be. There will be some packaging waste on site, but very little builders waste apart from packaging. And much of that is cardboard which can be re-cycled.

Of everything that comes into our factory, 97% of it leaves as a kit-set home. 

Of the 3% that doesn't go out as a home, 75% gets recycled.

All our steel, aluminium, polystyrene, and most of the packaging gets recycled. We have our own polystyrene recycling plant.

Our aluminium comes from NZ's greenest plant, with aluminium at 1.4kg of CO2e per kg on scope 1 & 2 basis

That means, that on average, we take about a suitcase full of rubbish to landfill. Compare that with a traditional build which usually has several skip loads to landfill.

Once you get to site, so long as the cardboard packaging is recycled (and that is mostly from the bathroom and kitchens), there is also a lot less rubbish that goes to landfill.

At EOL (End of Life) most of the materials in our houses will be recycled., with typically only the kitchen, bathroom, floor finishes and internal doors and pipes going to landfill. The steel, aluminium, polystyrene, glass, cables can all be easily recycled. Contrast this with treated timber, batts and gib from a traditional home, all of which will go to landfill.

So we are, without doubt, the greenest house manufacturer in NZ.

Treated timber cannot be recycled - It has to go to landfill - by law. You can't burn it.

Gib is not recycled. Neither are spare bits of pink batts.

So by being green, it saves the customer money by minimising waste to landfill.

Our aluminium comes from a plant that is CEMAS certified - 1.4 kg of CO2/kg (90% better than the global average)

The steel in our homes produces about 6.3 kg of CO2

We use energy efficient heat-pumps that are powered by electricity - of which an increasing amount come from renewables.

We do not use wood burners which release CO2 back into the atmosphere.

The amount  of CO2 saved by having a home over twice as well insulated as the average NZ home dwarfs the amount of CO2 it takes to manufacture a home.
