“Your assumptions are your windows on the world. Scrub them off every once in a while, or the light won’t come in.”
This quote has inspired us to share and untangle some common assumptions about being warm in winter. With record numbers of enquiries, property assessments and home energy product sales, it’s time for a recap on how to be warm, dry and energy efficient. Check back again next week for more myths debunked.
- Insulating my home/rental is an expensive upfront cost I can’t afford
Ratepayers can pay just $20-30/month for insulation with a rates loan from GWRC. It’s a fantastic and safe way to access up to $3,900 for insulation costs, repayable over max. 9 years via your property rates. It takes around a fortnight for the paperwork to come through, so you can warm up and save on bills quickly with install asap thereafter. This has to be Wellington region’s best kept secret!
Alternatively we offer a short term 0% interest loan repayable over 6 -12 months, across our insulation, heating, ventilation and LED downlight supply and install services. A great way to have a bit more time to pay off what you need now. Find out more about these repayment plans.
Don’t forget – insulation costs are quickly offset by improved health, comfort and quality of life. As insulation now lasts around 50 years and is a legal requirement for all rentals by July 2019, this is a crucial long term investment for any homeowner and is much more affordable than you think.
- The subsidies have run out (or I’m not eligible)
Not true! There are a limited number of subsidies still available, but only until June 2018. Once they are gone, they are gone!
If you are renting have a Community Services Card then your landlord may be able to get half price insulation with Government funding. If you own your own home and have a Community Services Card, then you may also be able to get funding of up to 50%from Sustainability Trust and our partners to help pay for insulation. If you think you could apply then do it, now, before they run out!
Psst – eligible homeowners can get both special offers – half price insulation and put the rest of the costs onto one of the above repayment plans, making insulation even more affordable. Contact us today to find out more.
- Heating? Insulation? Just put an extra jumper on!
A jumper will warm up your body, but the actual temperature inside your home needs heat to prevent moisture and housing-related health issues. If a room is cold and damp then it will cause mould and dust mites, which can lead to serious health issues like pneumonia, asthma and rheumatic fever. Sadly, over one in four Kiwis suffers from asthma, and your home environment is the number one way to prevent and treat poor health.
Bedrooms should be at least 16 degrees and living areas 18-20 degrees, according to the WHO. As a general guide, most New Zealand homes built before 1978 need ceiling and underfloor insulation, fixed heating in the living space and radiant heaters in the bedroom, to counteract the problems caused by poor building construction standards. The quality, thickness and fit of insulation is crucial, as well as the size and type of heating.
Want to know more? Then register for a Warm Dry Homes workshop, book a home assessment with one of our experts, or read EECA’s home heating info guide. If you have a housing related health issue then you may be be to get extra help from Warm Fuzzies.
- I need thick, thermal lined curtains but they are are hard to get and expensive
Thermal backing make little or no difference to heat retention. Call it an old wives tale, mistake or assumption, put simply it’s wrong. What matters is multiple layers of fabric that trap air and create a barrier between the curtains and the window. So the perfect recipe for curtains is good quality curtain material, which is lined with at least one layer of fabric – simple cotton will do the job. The fit too is crucial, as curtains need to fully cover windows including top and bottom, ideally floor length with a pelmet too.
We offer a Curtain and Tailoring Service for paying customers, so get in touch today to get your curtains lined or to commission a full set. All profits are invested into free curtains for Community Services Card holders via the Wellington Curtain Bank, so that’s amazing quality for your home, whilst helping others too.
We hope this has helped you to see the light. Check back again next week for more common assumptions debunked, or feel free to get in touch for personalised advice and a property assessment.
Earth Day is here again, this Saturday 22 April 2017. A reminder that we only have one planet to live on and that we need to pay attention to how we take care of it.
Astronomers say there may be a habitable planet about 39 light years away circling around a dwarf star in the constellation of Cetus. But we won’t be swapping earths anytime soon. The hard truth is, there’s no one else out there creating the environmental degradation– it’s you and me baby!
Our challenge this Earth Day, as stewards of our city, country and planet, is to take real and lasting actions to reduce our environmental impact. Every choice we make has consequences, so being informed is the first small step to making a difference. This year’s Earth Day is focused on environmental literacy so here are some practical suggestions for you to learn what, why and how to save this precious earth we call home.
- Get involved: Indulge your curiosity by learning about environmental issues such as climate change, and inspirational solutions, such as clean rivers, electric vehicles or renewable energy. Check out our library for interesting reading and watching, attend events, have a debate night with friends, book your kids onto a workshop, research online – whatever you do, actively educate yourself and share your new knowledge widely.
- Know what your actual impact is: It’s very easy to calculate your personal impact – and information is the first step to reducing it. An average Kiwi’s carbon emissions are around 18 tonnes a year. This needs to drop to around 2 tonnes a year to get the world healthy. At Sustainability Trust we use Catalyst’s Annual Carbon Emissions (ACE) Calculator, and offset our emissions with Ekos and local carbon credits sourced from Southland forests. Everything counts – so how can you reduce yours?
- Reduce-Reduce-Reduce: Do everything you can to limit or reduce your environmental impact. Eat less meat and dairy (or none at all!). Walk, cycle, swim. Drive an electric car. Reuse, recycle, compost. Make a warm, energy-efficient home with long life ceiling and underfloor insulation, LED lights, good quality fitted curtains, double glazing (or cheaper alternatives like window film), use water wisely – do everything you can to get that energy use and power bill down.
- Invest and divest: Make sure you invest in climate friendly companies. Put simply, the more money that is behind the right causes will help balance out the markets long term. We recommend investing in renewable energy generators such as Meridian, Mighty River Power, wind turbine and solar manufacturers, and not buying into environmentally harmful industries such as fossil fuel companies or agriculture (especially dairy).
- There’s an election coming up: This September we’re back at the polls. Make sure that you vote for candidates with robust environmental credentials. Do your research, attend meetings, ask questions, write letters, sign petitions. Whoever makes it in to government, let them know that the environment counts.
As a local grassroots organisation, Sustainability Trust is engaged in practical action across the Wellington region. We are so enthusiastic that our community across New Zealand can and are making steps in the right direction. Earth Day 2017 provides us with a strong reminder that we need to take action, both personally and by helping ensure large decision makers play their part too.
If we can help you in any way, please give us a call on 0508 78 78 24.
A story about a Wellington couple doing everything they can to live sustainably, a little inspiration for those of us doing what we can, when we can but who would like to do more.
The bananas didn’t make it this year, but the corn is going strong.
Mornington couple Ken and Anne Simpson have proved that real gardening, the kind that feeds a family, is possible in windy Wellington.
They have an abundant, sprawling 400sqm fruit, nut and vegetable garden on a slope that boasts apples, figs, plums, kiwifruit, gooseberries, cranberries, peaches and nectarines among the usual vegetables. Out the front they’ve created self-generating bush with 50 different native species spread over a 400sqm slope.
All this in a suburban setting just five minutes’ drive from the Wellington CBD.
“It provides food for us and the birds, fuel for the wood-burner, and nectar and pollen for bees. It is a constant source of interest, pleasure, surprises, and challenges,” Anne says.
Our capital city is not known for its easy climate, and Ken says it’s been experimentation that brought success.
They “liberated” the back lawn about 16 years ago and since then have been figuring out which way the wind hits it, which plants will protect each other, testing the limits and using the wisdom of companion planting to get things growing.
They’ve added a beehive, chickens (the poo is great fertiliser), compost heaps, worm farms – the backyard is teeming with life.
Anne says she was initially inspired to grow their own organic food when she read about genetically modified food.
“We all actually ought to be doing this, so we thought ‘What can we do in a capital city?’, we needed to find out what was possible.”
One thing leads to another, says Anne, and the next thing you know you’ve got solar panels.
The couple’s efforts to be self-sufficient haven’t been limited to the garden – they’ve got a 1000-litre water tank, and solar panels which generate about 2800 kw a year.
They’ve tried to make their carbon footprint as small as possible – making their own green cleaning products, avoiding plastic packaging, and making their home more energy efficient.
They’ have a mechanical ventilation system which they say sorted condensation overnight, with it the mould. They have insulation in the walls, ceiling and underfloor, secondary window glazing and have gradually changed their lights to LEDs.
Most recently they called in Sustainability Trust to upgrade their bathroom lights to LEDs and to fill in the gaps in the ceiling insulation which had been required with conventional downlights.
The investment Ken and Anne have made has paid off – their winter power bill now averages about $60 a month.
The Simpsons are shortly moving to Scotland to restart a life there, and are passing the home on to another family next month.
“I’ve learned lots,” says Anne. “We’ve started something here and hopefully we’ll start something else.”
For anyone inspired by what they’ve done, Anne says: “Just start with a little bit. Try it out and see what you can accomplish. Do a bit of dreaming and be a bit inspired by things you read. Have a go at things you would like to do.”
And from Ken: “Get advice”.

What makes a good heater? Ultimately, a heater needs to deliver warmth to where you sit or sleep, but there is plenty of science and technology behind how they work that can be confusing. This simple explanation of how heaters work and the differences between some popular options should help you work out what heating is best for you, your budget and your energy use this winter.
All portable electric heaters convert one Watt (W) of electricity to 1W of heat. Or ‘1-to-1’ in heater tech-speak. Therefore, effective heat distribution is what makes all the difference, otherwise you’re paying to warm the spiders on the ceiling!
Sustainability Trust has some great options for eco-friendly home heating, from full home (central or ducted), floor or wall mounted heat pumps, and wood burners too.
Radiant heaters are a good option for room-specific heating at a lower price point than heat pumps or wood burners, or as a supplement to existing fixed heating.
Our premium Atlantic Tatou heater delivers 70% radiant heat and 30% convection. Radiant heat, like the sun, is most ideal since it heats the surfaces around you. It distributes heat at floor level for longer meaning you get your money’s worth by feeling warmer sooner. The Tatou features a high-tech thermostat and timer, and can either be free standing or wall mounted.
An alternative to the Tatou is our Kent micathermic range. These free standing heaters provide a combination of radiant (20%) and convection heat (80% – heating the air), distributed three ways: out both sides as well as above the unit. It’s the sideways radiant heat that gives the micathermic units an edge over regular oil column heaters. They are small, portable and also feature a thermostat to regulate the desired temperature.
If you want to keep your old oil column heater, consider using a small desk fan to re-circulate warm air that has settled around the ceiling. This prevents ‘heat stratification’. Small fans are cheap to run.
Here are some other useful reminders and tips to help navigate the world of radiant portable heaters:
Be careful around the terms ‘efficient’ and ‘economical’. Remember, all portable electric heaters convert ‘1-to-1’. Efficiencies are achieved instead:
- If heat can be distributed at floor level so you feel warmer quicker
- By using a thermostat to maintain a comfortable temperature without the heater running continuously
Some heaters may be considered economical because they cost less to buy; others because they draw little electricity for equally little heat but an under-sized heater will not keep you warm. For a medium-large room (60-100 cubic metres), aim for 2000-2500W output. Know the Wattage before purchasing.
As a general rule, aim to heat a room to at least 20 degrees C to reduce the risk of any illnesses linked to cold, damp housing. Your own comfort level is specific to you, but the higher you set your thermostat temperature, the more the heater will be running. A 2500W heater will cost 70c per hour, running continuously (28c/kWh). Observe how often the thermostat on your heater switches off and on across an hour and adjust accordingly.
Finally, make life easier for your heater. Get home insulation up to standard, block draughts around windows and doors, and install doubled-lined curtains – preferably floor length. This will all help keep that precious heat in!
Warm regards, David.
In many parts of New Zealand, households are not charged for domestic water consumption and we traditionally think of water as a free and abundant resource. Increasingly we are realising that this is far from the truth – most recently Auckland and Havelock North have been hit hard, but with record breaking water wastage, access to clean, safe water is a global crisis. Today is World Water Day 2017 so here are some tips to help us all use water more wisely.
An average household’s water use is made up from:
Bathroom – 25%
Toilet – 25%
Garden – 20%
Laundry – 20%
Kitchen – 10%
How can you reduce your use?
- Fix leaky taps and toilets
- Switch to a low flow shower head to reduce water use by up to 50%. We recommend Methven’s Kiri Satinjet low flow shower heads which have great pressure and an in-built flow restrictor
- Alternatively, fit a flow reducer behind your existing shower head
- Insulate hot water pipes to keep water warm and speed up hot water flow from taps
- Install tap aerators to reduce unnecessary water flow from taps, yet maintain water pressure
- Reduce the amount of water used per toilet flush with a toilet gizmo
- When buying new appliances, only buy ones with efficient water ratings
Did you know…
All piped water is treated to drinking water standards, yet we only drink 3% of the water that comes from our taps. That means that 97% of the expensive treated water that is piped into our homes is used where untreated water could be used.
Water harvesting is a sustainable way to gather and use water. Rainwater can easily be captured and used both in the home and in the gardens. Check with your local authority, your local public health service or on the Ministry of Health’s website for guidance and requirements on water treatment. 200ltr emergency water tanks are now available via Wellington City Council, or shop for 800ltr water saving tanks from us.
Greywater systems can also be installed to reuse waste water from washing machines, showers, baths and basins. There are a range of options for collecting and using greywater, depending on the source of the greywater and the use intended – talk to the council about rules, legislation and building consent.
Contact us if you would like any more information on how to reduce or reuse water in the home, and don’t forget that if you book a Home Energy Assessment you can get 50% off water/energy saving products.
Here at Sustainability Trust we do our best to walk the talk and limit our carbon footprint.
We’ve got five different bins in our kitchen, a worm farm, and electric bike, solar panels, insulation, energy efficient heating and lighting, sustainable paper and napkins in our loos and are often seen tutting at each other for leaving lights on in empty rooms.
But we’ve still got a business to run, a large part of which involves zipping around town in cars to talk to people in their homes about what measures they can take to create a more energy efficient and healthier home.
We also occasionally travel by plane, use on-grid electricity and generate waste. We estimate we put 43 tonnes of carbon into the atmosphere in 2015, so we’ve decided to work with Ekos to offset those emissions.
Ekos is led by Dr Sean Weaver, the original chairperson of Sustainability Trust, and we’re very pleased to working again with one of our founders.
Ekos is working in partnership with Maori landowners in Southland to preserve 738ha of indigenous rainforest, the Rarakau Rainforest Conservation Project.
The project produces 2430 tonnes of carbon offsets each year – we have ‘bought’ some of those to make up for what we put into the atmosphere.
You could say that we have 13ha of rainforest working for us. The credits are calculated based on what would have happened if the carbon project was not in place – the trees would have been cut down and sold and released carbon. This project and the credits are internationally certified.
As many of you know, we provide products and services to homes and businesses that reduce emissions. In 2015 we reckon we provided services that potentially avoided 450 tonnes of carbon emissions!
We’re also always looking to improve, which this year will include swapping one of our petrol cars for an electric – we’d love to swap all of them at once, but we’re working within limited means!
We’re going to be working with Ekos a bit more closely this year to make it easier for Wellington businesses to offset their carbon emissions, so if you, or your business, wants to join an increasing number of people achieving carbon neutrality by buying offsets, please talk to us and we can help make that a reality.
Electricity prices have increased 70% over the last 20 years and that’s accounting for inflation. So what can you do about it? Here’s some help to understand what makes up your bill, then how to reduce it.
AVERAGE POWER BILL BREAK DOWN
Hot Water 30%
Space heating/cooling 34%
Other appliances 13%
- The sun is the best heat source we have, make sure no vegetation is blocking direct sunlight into the home and make sure curtains are open during the day
- Dry air is easier to heat, look to reduce moisture sources inside and outside the house and ventilate for 30mins daily
- Insulate ceiling and underfloor. Note that standard downlights rapidly affect ceiling insulation’s performance so look to change to insulation coverable LED Downlights
- Check your shower flow by grabbing a standard 10L household bucket and run your shower for one minute. If you can fill the bucket in under a minute your shower flow is too high and big savings can be made by using a low flow shower head. If it fills in 30 seconds you could be saving $150 per person per year based on a five-minute shower only.
- Reduce your hot water temperature in the warmer months. Even better, install a hot water cylinder wrap, or invest in a more efficient water heating solution such as a solar hot water heat pump.
- Use efficient heat sources. Generally heat pumps, wood burners and flued gas heating. Electric heating can add up very quick if used for longer periods.
- Get in contact if you would like a free 2hr Home Energy Assessment (Wellington and Upper Hutt only) or a free Smart Homes Assessment on heating, insulation, lighting, ventilation (any homeowner).

Rubbish. Trash. Garbage. Lots of us are reducing our rubbish at home – we take fabric shopping bags to and from the supermarket, wash out yogurt containers, separate glass, even feed the worms, and as a result send smaller bags, less frequently, to the landfill. Go us! But how does your business or enterprise fare?
Here at Sustainability Trust, we have been auditing the waste of Wellington businesses for some years now. In general, businesses do a pretty good job of recycling cardboard, but in many other areas there are some big improvements that can be made. Of course it’s harder with a large workforce to carrel, but have hope – we can help.
The key starting place for businesses is a review of where its consumables (throw away items) are coming from, and what is going into the waste. This is actually more urgent than addressing the recycling!
Paper products – e.g. printing and sanitary – are New Zealand’s biggest office consumables. Using a copy paper that comes from fully recycled stock has way less impact that one from virgin sources, and these days recycled paper quality is comparable to other papers. It’s a few years old now, but the Sustainable Business Council review, Which Paper? Is a good place to start your decision making journey. Always check for environmental certifications too.
Changing the way we use paper and thinking about what goes to waste can make a big difference. Making the shift to tracking and editing documents on screen, or screen-based meeting presentations can significantly reduce paper printing and wastage.
Another effective tip is to have two paper trays for collection of waste A4 paper – one for GOOS paper (good on one side) that can be reused for notes (or reuse products like these notebooks) and one for paper that is already printed on both sides and will need to be directed to recycling.
Paper to wipe your, ah, hands on, is easy not to think too hard about – when you are in the moment you will take what’s on offer, right? Sustainability Trust are now suppliers of the Greencane range of sanitary papers – with 70% bamboo and sugarcane, these paper products are sourced from a more sustainable supply chain, do not use a chlorine based bleach process, and quickly and comprehensibly breaks down once discarded.
Switching to less environmentally impacting products is a small move you can make easily. So don’t wait – change in-office behaviours or call us for help today.
