As I've tried to emphasise in this column, Richard's presentation highlighted the economic savings associated with eco-design. Rising power bills concern us both.
While I have written that electricity rates are on track to double in the next 10 years, Richard shared information that they could double in as little as eight. In in the case of our household, a rise from $22/month to $44/month would not break the bank, but for families paying $300, a rise to $600 could be devastating.
When this is added to the recent radical increases in homeowners' insurance, the effects could be profoundly negative for local businesses due to less available disposable income of the average Wanganui resident.
And beyond that, as electricity rates rise, more people may choose not to heat their homes because they cannot afford to.
This would exacerbate an already major challenge facing New Zealand: Health problems associated with cool, damp homes.
Here is some information from the eco-design advisor network (Participating councils: Auckland, Hamilton, Palmerston North, Kapiti Coast, Lower Hutt, and Nelson): New Zealand homes are generally cold, damp, unhealthy and inefficient in energy and water use:
NZ homes are on average 6C below World Health Organisation recommended minimum temperatures in winter.
80 per cent of NZ homes are inadequately insulated.
45 per cent of NZ homes are mouldy.
NZ has the second-highest rate of asthma in the world, and an excess winter mortality of 1600, a much higher rate than other OECD countries.
Cold, damp homes pose serious health risks, particularly for the most vulnerable groups in the community who spend the most time at home.
Sustainability is often presented as a triangle including environmental quality, human needs, and economic viability.
This is a model I have used as a teacher for 20 years. But the more I learn about the majority of housing stock in New Zealand, a different triangle comes to my mind - a sort of Bermuda Triangle where things such as money and health disappear.
The three points of this sub-standard housing triangle are: unhealthy, inefficient, wasteful.
The eco-design advisers are doing amazing work to combat the Bermuda Triangle of New Zealand homes, and rescuing families from the netherworld of cold and mould.
