Energy Efficiency – staying warm without turning up the thermostat
Now the weather has turned cold in the UK, our thoughts have turned to how we can keep warm – indoors as well as outdoors. For many of us that simply means turning up the thermostat another notch. But with reports of fuel price hikes of 7% and higher imminent, suddenly energy efficiency has become an even hotter topic.
Starting with our existing homes, the key word is insulation. The idea is to keep the heat in and the cold out. 25% goes out the roof – so lay up to 270mm of insulation; 35% escapes through the walls. Combat this by having cavity wall insulation. If you have one of the 6 million solid brick wall homes, consider dry wall lining.
Windows and draughts account for 25% of heat loss in our homes. So plug the gaps with filler, use draught excluders on your exterior doors (and don’t forget the letter box). If you can afford it, think about double (or even triple) glazing. If that’s too costly, secondary glazing is a cheaper alternative.
Next, find out how much electricity you use (or waste). Buy, or rent from your local library, an electricity monitor. These clever gadgets show you how much electricity you are using in the home. Flick the kettle on and you’ll see it costs a shocking 25p to boil water if it was to be left on continuously for one hour. So fill the kettle only with the amount of water you need and don’t boil, walk away and then have to reboil.
Look at what you leave on standby overnight – do you need to? Get a standby isolator or switch the items off at the wall (except the Sky box, which would then need reprogramming). Don’t leave old style mobiles charging overnight as these ‘vampire’ gadgets continue to suck electricity even once the battery is fully charged.
Or take a look at a more permanent electricity reduction solution. The VPhase is a new device that through independent testing has been shown to cut electricity bills (typically by 10%), reduce energy use and lower carbon emissions. Find out how much money and CO2 you could save with the interactive tool at www.vphase.co.uk
VPhase uses voltage optimisation technology to reduce and manage the voltage coming into your home, making your electrical appliances use less electricity and cost less to run. Unlike smart meters which require a change in behavior, the VPhase device works immediately, without any need for a change in lifestyle.
The unit costs around £250 installed when fitted at the same time as a fuse box, and can be quickly and easily fitted by a qualified electrician. The VPhase has a five-year warranty and with payback periods typically less than this it represents a risk free green investment.
If you’re considering buying a new house in the UK, you’ll find that they are at least 25% more energy efficient than houses build pre-2006 (and at least 50% more than a Victorian property and probably more) through legislation. Housebuilders are achieving such greater efficiency by using better insulants when building,
sealing gaps better and by preventing thermal ‘bridging’, which allows the cold to travel from the outside in via metal pins or ties.
In some cases, the net result is homes that require little or no heating – even in winter. The latest built homes don’t even have radiators installed. Generally, energy efficient under-floor heating provides what heating they do require. In other examples, mechanical heat ventilation recovery units recirculate rising hot air to keep the homes warm at ground level.

The homes at AlmaVerde, on Portugal’s Algarve, have been built to a year-round 26C interior temperature
In more temperate foreign countries, where many Britons choose to buy a holiday home, or retirement property, the same technology that provides heating in winter is reversed to provide air-conditioned cooling in summer. If the electricity required is generated from a renewable energy source, such as solar, there is no in-use CO2 impact, and electricity bills can be negligible.
The housebuilders and developers who are the members of Sustain Worldwide (www.sustainworldwide.com) are each building homes, resorts and communities around the world where energy efficient, eco-friendly and sustainably constructed properties and communities are the norm.
Sustain Worldwide Chief Executive Anwar Harland-Khan said: “The energy-efficient homes of today are stylish, beautifully finished, invariably with warm and light spaces for living. It comes as no surprise that sustainably built homes are now standing tallest of all, while the walls of conventionally built homes are starting to show cracks.”

The advantage of sustainable homes
GREEN is the colour of choice for new homes. Movie star Leonardo di Caprio is building an eco home on his own private Caribbean island. Julia Roberts and George Clooney too are green devotees. Brad Pitt has been involved with constructing several in New Orleans. Even Manchester United footballer Gary Neville is trying to build an eco home in the hills outside Manchester.
The reason green, eco or sustainable (the words are used interchangeably) have become the new luxury is for many people a combination of our growing awareness of climate change (images of polar bears stranded on melting ice flows is potent), and a general groundswell of opinion that we need to be just a little more aware of how increasingly scarce are natural resources are becoming.
So, how, you might ask, do our homes have an impact on melting ice flows? Well, our homes account for 25% of the CO2 – a greenhouse gas – emissions that scientists say is contributing to irreversible climate change. The effect is not only melting ice flows but rising sea levels, increasing outbreaks of drought and famine, and some say the upsurge in other natural phenomena like tsunamis.
For some of us the issues are a little less high blown. In these straitened times, simply saving a few hundred pounds a year on your heating and electricity bills is a big incentive to make one’s home more energy efficient. Inexpensive ways to reduce bills, lessen CO2 emissions and create a more pleasant temperature include laying more insulation, and choosing energy efficient appliances.
When it comes to new homes – either in the UK, or overseas – and whether you are buying a permanent home, a holiday retreat, or building up your investment portfolio, sustainable design and build represents the future of global property. The sustainably built homes of today are stylish, beautifully finished, invariably with warm and light spaces for living – and in many cases they look just like a conventional house.
Those who understand this philosophy when buying a new home are in an enlightened and beneficial situation. Their homes will have cleaner air and a more pleasant temperature for comfort and well-being; if the paint and furniture is made from non-toxic materials it’ll be better for their health and their children’s too. So, not only is there a feel good factor, there’s a beneficial long-term legacy to leave the next generation.

Peek inside London’s most Sustainable Homes
If you’re interested in Sutainable Housing, architecture or design then you’ll be very interested in Open House London this Autumn when 700 houses in London will be open to the public.
The event is organised by the architecture organisation Open City and takes place over the weekend of 18-19 September 2010.
‘The initiative is a simple but powerful concept: hundreds of great buildings of all types and periods open up their doors to all, completely for FREE. It is a truly city-wide celebration of the buildings, places and neighbourhoods where we live, work and play, and is your opportunity to get out and get under the skin of London’s amazing architecture’ says the Open House website.
The ‘open houses’ range from small private home to major lndmarks such as the BT Tower and there will be lots of events such as cycle tours, architects talks and neighbourhood walks to interest and inspire you over the weekend.
Here at The Big Property List we’re particularly interested in the Sustainable Housing element and there should be plenty of eco-homes on show boasting sustainable designs such as The Coach House, 39 Parkholme Road, Retro-eco House and Zero Carbon Loft.
If you’re visiting any of these sustainable houses over the course of the weekend, why not email your pictures and notes to admin (at) thebigpropertylist.co.uk and we’ll publish them here on our blog?
For the full list of open houses you can visit the Open House website or order a guide to see what is available near you – some venues need to be booked in advance.
