Greenest Building in the World

September 1, 2011

Just read an interesting article on Smart Planet titled “Greenest building in world uses no water or electricity”

It’s a pretty cool building – looks like it’s offices and residential apartments. It has solar panels all over it that provide the electricity for the building and also to power the ground source heat pump (GSHP) that is underneath. All the water that falls on the building is collected and filtered to be used inside.

I must admit, that reading it I felt like we’re not far off with our house. All of the water that falls on our roof is collected into a 5000 litre tank and is routed to the toilets, washing machine and outside taps. We’re not drinking it because I didn’t find a domestic solution that gave me comfort that it would be safe. I’m hoping to get solar panels installed which should provide enough electricity to power the GSHP and contribute to our electricity generally.

Renewable Heat Premium Payment Scheme

August 25, 2011

Today I made an application for the Renewable Heat Premium Payment Scheme. My dad suggested I looked into it, so I did. Filled in a pretty straightforward form online (see www.energysavingtrust.org.uk) answering basic info as well as GSHP details, and hey presto, I’m told I’ll be awarded £1250 as soon as my system gets commissioned!

Fingers crossed this will be any day now – the guys who installed it managed to blow up the PCB and so it’s never actually worked. Commissioning the system will be a big relief – it’s all very impressive but I want to see it working before I get too excited and also, I get my £1250 quid!

I don’t know exactly what plans are afoot for Renewable Heat Incentive (RHI) payments which I believe will start next year, but I’m hoping I’ll be able to get something back from that too. That’s if the government’s spending cuts don’t get there first.

Stairs In Their Eyes

July 7, 2010

We’ve had a set of stairs in our designs that are central to the hallway. They go up halfway, you turn a corner and go back up the other half to the landing. We’ve decided to scrap the idea in favour of a straight set of stairs that splits left and right at the top. The implications are: 1) we lose a cupboard at the top of the stairs. 2) We end up with a bigger landing. 3) We end up with more hall space. 4) We gain a big cupboard under the stairs. 5) We lose direct access to the big living room from the kitchen (you now have to walk around the stairs). It’s a neater design, probably cheaper, and we like it. Phew.

Builder’s references

July 5, 2010

My wife and I spent a good part of Sunday visiting 2 couples who’d had similar work done to their houses nearby. They were both very generous with their time and were very open about their experiences. It was a very worthwhile process and we’re starting to feel much less like we’re going in blind. They both recommended their builders very highly which is fantastic – it gives us confidence that we’re going to be choosing between good guys.

In both cases, the families had installed hot water solar panels on the roof, and in this hot weather it’s providing more than enough hot water for their houses. It’s just such a shame that we don’t have south-facing roof space. I suppose we could put them on the ground???

Ice Energy Quotes

July 3, 2010

I received quotes from Ice Energy yesterday for the heating system. Interesting reading – they put plenty of details in which gives some confidence that they know what they’re doing and that they’ve done it before. They’ve recommended 2 heat pumps for some reason which I hope will become clear when I quiz them. The sums are quite eye-watering and I must admit a bit confusing. They price for the kit (pumps, piping, underfloor heating etc) and another price for installation. It’s not clear whether or not this includes digging the trenches for the ground source pipe work, and there are other pieces of work that they expect your main contractors to undertake.

There appear to be grants available (£3k for two heat pumps) as well as what appear to be generous government payments as part of the Renewable Heat Incentive Scheme (RHI). No doubt there will be schemes to borrow the capital required with government paybacks as your security.

Finding a quality, reliable builder

July 1, 2010

With so many horror stories about cowboy builders, this becomes a rather anxious process. However I’ve followed up on some of the recommendations that I’ve been given and had glowing reviews returned. This is very encouraging and I’m starting to feel a bit better about it. I’m hoping now, that with a good deal of preparation and choosing builders that come highly recommended, we’ll get some guys that are a pleasure to work with.

I read in my magazine a few tips for choosing your builder:

  1. Get recommendations, follow them up and ideally see the work they’ve done
  2. Prefer builders that put a sign up outside the property they’re renovating – it suggests they’re proud of their work
  3. Choose builders that are members of the FMB (federation of master builders)
  4. Ask your building regulations person at the local council for any tips
  5. Be wary of choosing the cheapest (particularly if they’re a lot cheaper than the others)

Insulating the walls a bad idea???

June 30, 2010

The idea of insulating the walls has exposed a flaw in the government’s Renewable Heat Incentive (RHI) scheme: the more energy you require to heat your house, the greater your potential returns (assuming you use a renewable heat source such as GSHP). This is counter-productive, as we should be encouraging home-owners to insulate heavily first. For example, say it costs £10k for me to insulate the walls through internal cladding. This reduces the size of the heat pump required, which means I get less payments from the government, over 23 years, possibly losing me £40k in revenue. If my increase in heating costs is £20k because I chose not to insulate, I’d still be financially better off. Of course, it’s not just about the financials, but it’s what drives most people’s behaviour, so if the government want to see a reduction in energy consumption, they’d do well to revise their ideas.

Hellifield Peel and their GSHP

June 29, 2010

A brilliant episode of Grand Designs showed a family bring a 12th century castle  back to life. At times it seems impossible and I had to hide behind the sofa. The result however is fabulous and a testament to what is possible. One part of the show that had always left me wondering was the Ground Source Heat Pump – how effective had it been for them? Installed throughout, the system was to be used to provide the hot water and heating (there was no gas and they wanted to avoid oil, just like us).  I was delighted then to find a video of Francis the owner talk about his experiences of living through 2 winters with the GSHP. Running a bed and breakfast there’s clearly an important demand for decent heating and hot water, and he claimed the GSHP did an admirable job providing these. You can see the video here: http://www.iceenergy.co.uk/hellifield-peel—c4-grand-designs-winner-_238/. This is just the kind of comfort I need before finalizing the heating system…

Grand Designs helps set expectations

June 22, 2010

My wife and I like to watch Grand Designs to remind ourselves that the project will be very stressful, that it will overrun in time and money and that we should steer clear of trying to manage the project ourselves. This sets our expectations, and hopefully will make for a more enjoyable project.

Ground Source Heat Pump in an old house

June 18, 2010

So here’s the dilemma. The house is old, badly insulated and without many options to improve it. Will a GSHP with under-floor heating be sufficient to warm the house in a cold winter? Or should we design in an auxiliary system – a traditional central heating system? There’s no gas in the area, so it would need to be oil presumably which I know is very expensive and rather out of sync with our goal of making an old house as environmentally friendly as possible.

We’d rather not have radiators all over the place, and like the idea of relying solely on GSHP (with the pump powered by our solar panels) but are we going to find ourselves freezing cold? We’ll have a few wood-buring stoves downstairs, so these rooms should be OK. But what about upstairs? My dad’s going to have a go at some sums. Anyone know how we should approach this?

See the oil tank? Alas, it's empty :-(

Batty

May 20, 2010

So it’s the day of planning permission deadline (8 weeks from application), and yesterday SODC decided to raise the issue of bats, long after the end of the consultation period had finished. This is very annoying and bad form on their part. They’ve agreed to extend the period whilst we get a ecologist’s report submitted but it’s really thrown a spanner in the works and will delay things dramatically. Seems they play by the rules when it suits them, and not when it doesn’t.

Bat Survey

March 30, 2010

Some news come in from the architect – another of his clients is renovating a property on the banks of the Thames, and the planning application has just been put on hold, 3 weeks after submission. The Conservation Officer said that the house was a good candidate for accommodating bats and that an ecological survey was required to ascertain the extent of the problem (if any). So now we’re on the look out for bats – hopefully we don’t find anything and the matter goes away. If we find bats, we’ll need to plan mitigating steps to sufficiently reduce the impact on our little furry friends whilst the building works take place.

Planning Permission

March 25, 2010

Our application for planning permission was submitted yesterday, so fingers crossed, everything will go well. As far as I understand, we don’t need to raise our green initiatives at this stage because they have no bearing on the matter. I think it’s a case of crossing fingers and toes that things go through successfully, so we can move ahead and take this house out of dereliction.

Measured Survey

December 14, 2009

We’re getting a measured survey done. One things that’s come to light is that the walls are solid brick. With no cavity, insulation is going to be a big problem. I’ve heard mixed views on the effectiveness of cladding inside, worst case scenario is you get unpleasant pockets of stale cold air. The roof we can insulate massively, which is clearly very important. When I was at school I learned that heat rises. I presume it still does.

Sued By Trespassers

December 10, 2009

I’ve just put up a load of signs to say “Danger: Keep Out”. I’ve read that you can be sued if someone breaks into your house and hurts themselves. Can’t say I didn’t warn them.

Eco versus aesthetics

December 5, 2009

We’ve got a bit of a dilemma. Whilst not listed, the building is in a conservation area, so we need to be careful about what we do. We’re keen that it remains sympathetic to the environment anyway of course, but we also want it to be as eco friendly as possible. Solar panels on the roofs probably won’t fit! We’re thinking about a separate array of panels on the ground, or possibly on the garage roof. I’ve been looking for solar tiles  – they’re coming on but the companies that supply them are very few and very far between. I think a couple of years will be enough for the market demand to see these come to fruition.

Choosing an Architect

November 26, 2009

It’s a close call between 3 of them (the “green architect” we spoke was out of the running. He was too shy and lacked the confidence we wanted to see which was a shame. We’ve decided we’ll have to push the green issues and have someone who good at executing projects) and we’re going to feel bad having to let down 2 of these. Our favourite by a whisker is Richard Potter, so I ring a few past clients and see what they say. They were very generous with their time and strongly recommended him. We don’t need any more persuading, so we get in touch and give him the good news.

My House

November 24, 2009

The house I bought is dilapidated and is in a conservation area, and an “Area of Outstanding National Beauty” in South Oxfordshire. It is of red brick construction and was built in the 1830s. The walls are solid brick (no cavity), the windows are single glazed and rotten. There is almost no insulation (though this is academic – there is no heating!). It is south-facing, though has limited south-facing roof area. There’s loads of garden with it.

This Old House - How Can I Reduce Its Impact on the Environment?

As I understand, the main opportunities for me are to install:

  • a Ground Source Heat Pump which will provide underfloor heating
  • photo-voltaic solar panels
  • hot water solar panels
  • rain-water harvesting
  • as good insulation as possible
  • double glazing

Interviewing Architects

November 22, 2009

We’ve now interviewed 8 architects on site. We’ve made notes as best we can so we remember who’s who. We wanted to know if we got on with them, did they sound knowledgeable, were they practical. Did they have environmental experience and what were their similar projects like?

It’s ours!

November 10, 2009

So after few ups and downs, we’ve completed and bought the house! What a feeling. A good price for it too! I think that there’s limited interest because there’s so much work that needs doing to it.

Bad Insulation = Not Green

The insulation could be improved...

My dad asks me some practical questions like where are the services: water, gas, sewerage… I don’t know! I guess there’s going to be a lot of unknowns that need discovering.
