Personal story:

I had a science education and after an MSc at Wye College in Kent (now sadly closed), became more interested in conservation and the environment. When I moved to Haringey in about 1995 I became aware of the local environmental activism going on around me. In about 2002, I became concerned about global warming and so started doing things in a low carbon way. Firstly, by stopping flying. I had already given up my car, so using public transport was normal for me.
Having been to many an open home event myself, I got interested in retrofit, and as I started preparing for retirement I looked around for a house with a garden that I could make energy efficient. I wanted to stay in London and in Haringey, where my social networks are.
I first saw the house in the summer of 2014 and moved in right at the end of 2014. The house was really in a bad way, with an EPC of F. I spent 2015, lining up an architect and builders, bashing the budget into shape and raising the money. I moved out again in March 2016 for the builders to start work and moved back in mind-September 2016. There is still a lot to do! The basics are in place though and I am very much enjoying living in such a light, energy efficient home that is helping the environment.

Motivations:

My father was an electrical engineer, so I have always taken a bit of an interest in energy – how we generate it and how we use it.
Having helped to organise a couple of open home/energy reduction events I was keen to try retrofit for myself. The main motivation for me was reducing my carbon emissions.

Property background:

1920s ex-Council housing, semi-detached. Ground floor and first floor EPC on purchase grade F. EPC in July 2016 grade D

Width 7.15 metres, depth 4.5 metres, floor area 32.18 square metres

Key changes made:

  • All windows replaced with Rationel triple glazed units.
  • External wall insulation – Pavatex wood fibre
  • 30cms wood fibre loft insulation
  • There is Kingspan floor insulation (ground slab, membrane, insulation, screed, underlay and wood floor)
  • Envirovent Positive Input Ventilation (PIV) loft mounted unit
  • Morso Wood burning stove Model 7443 rated output 6 kW
  • Magic Box Thermodynamic Solar Water Heating Panel
  • Eight standard Panasonic Solar PV panels (4 east facing and 4 west) Area = 1053×1590 millimetres 2.64 kWp
  • LEDs throughout
  • A rated Induction hob plus electric oven, A+ washing machine, A fridge/freezer
  • Water butts on all external down pipes – planned
Measures installed in detail:

  • External Wall Insulation
  • Floor Insulation
  • Loft Insulation
  • Low Energy Lighting
  • Low Energy Appliances
  • Solar Photovoltaic
  • Solar Thermal water heating
  • Triple Glazing
  • Water Saving Devices
  • Whole House Ventilation Heat Recovery
  • Wood Burning Stove
Benefits of work carried out:

It is a bit difficult to separate out the benefits of the environmental work from the general house upgrade, but, of course, the house is much more comfortable to live in. There are no draughts and once the wood burner is going well the living area has a good feel to it.

Favourite feature:

The triple glazed windows (by Rationnel) enabled me to have the back wall of the house fitted with large glass doors and windows. This means that the garden has become part of the living area!

Project update:

The basic retrofit is complete – but, inevitably there have been one or two “glitches” to sort out.

The baffles in the wood burner were not correctly placed last winter, so I am hoping for better heat output this coming winter.

The thermostat in the water tank of the Magic Box system was not working properly, so finally after 9 months of nagging, the system is now much quieter and using less electricity (I think).

I have still to purchase water butts for the garden.

The house has been hot over the summer (but not over 26 degrees C), so probably some exterior blinds are needed on the back windows for very sunny days.

The solar pv is performing better than modelled, and now the inverter is hooked up to my router I can see everyday how much I generate. I am not convinced that I am making best use of my own electricity, so I need someone to come and check this.
