Low Carbon Lifestyles
Carbon in isolation? Can you ignore other issues?
Water
Material Resource efficency v Waste
Natural v Chemicals & Health & Safety
They all have a Carbon load
So I think not
Carbon in Fuel, Energy, Heat?
Fossil Fuels release CO2 when burned Transport: people and goods: fuel
Heating Lighting Cooling Ventilating
Power to engines, pumps, etc.
Communications & IT power to and
cooling of computers and servers
Wasted fuel, energy, heat and coolth
Carbon in Water?
Chemicals & Purifying, Pumping,
Irrigating, Softening, Heating, Washing,
Cleaning, Bathing, Power Showering,
Wasted water: leaks, excess and
evaporation
Bottled water from any distance
Food miles
Carbon in Materials?
Embodied carbon in materials
In buildings, purchases, goods,
Food, water and drink miles
And in wasted materials
And dont forget methane from waste in
landfill (21 x GWP of CO2)

Look at the buildings first
Multifunctional Community Buildings Or other buildings put to community use
Potential 7 day week and up to 24 hour
day use
Maximise the spread of energy
demands through the 24 hours
Intermittent use and intermittent
heating causes inefficiency 05/04/2008 NGS 2008 SpecifyingForALowCarbonLifestyle 57

Schools
Does it need an extension or addition? Or a better time table?
Maximise/optimise use of rooms
Bigger rooms or a better furniture
layout
CSR points: offer space to community
Look at the building fabric
Is it well insulated, airtight and coldbridge free?
Could it be improved towards zero
carbon demand?
Does insulation control solar gains?
Insulation characteristics: Thermal
Resistance? Thermal Mass? Thermal
Inertia? Decrement? Hygroscopicity?

Energy
TechnologiesReduce demand and the carbon load of energy
Reduce or avoid reliance on grid supplied energy
Distributed v Dispersed or Local
Services Grid supply is created elsewhere
supporting elsewhere economies
Grid supply has transmission losses
Infrastructure is unsightly, expensive to
create and expensive to extend Local supply supports local economy
Make it and use it locally
Off-grid communities and applications canavoid expenses
Renewables and local supply
Avoid extending grid at great expense
Solar thermal is economic for hot water and inwall or in floor heating
Wind turbines built to supply local demands
Solar Photo Voltaic power can be economic tosupply specific small off-grid demands
Heat extracted from exhaust: heat water
Balanced mix work better than individual
If grid available: feed excess to grid
Ground source heat pumps
Effective efficient supply of energy
More economic to install as part of a new
development
Install when site investigation or piling occurs
Uneconomic to retrofit
Less efficient if heating and cooling
Can be incorporated in pavement and tennis
courts as large solar panels
Water Source Heat pumps
Economic to install if water source is
close by
Can provide efficient economic energy
Thermal Pollution in small or static
water sources
Air source heat pumps
Can provide economic source of energyfor heating and cooling
Create local thermal pollution
Can exploit others thermal pollution
Retrofit is unsightly
just like air conditioning units,
more round the back than ever
can be in attic spaces

Larger Systems
Often work better than many small Overheads of many similar parts
Inefficiency of many smaller parts
Wind turbines are an obvious example
Domestic roof mounted turbines often cannotwork well and deliver little energy
Large wind turbines serving many can be big
enough to generate good supply
Private Heat Power Comms.
Expensive infrastructure if dispersedcommunity
Relatively cheap to place during
construction more expensive to retrofit
Balance the demand loading and the
supply appliance sizes of
multifunctional buildings if part of the
community
CHP Combined Heat and power
More efficient than Power only, whilst heatand water goes up the cooling towers
But balanced demands are important too
Domestic demands relatively low across the dayand higher in the evening and weekend
Commercial demands high in the day low in the
evening and night, low to zero at weekend
Hospitals 24 hour operation lower demand at night
Universities can balance education in day and
residential in the evening and weekends
Wind
Hockerton village are buying a second-
hand big wind turbine to power village
Same village successfully objected to
HHPs wind turbine for 3 years
Swaffham village had 1turbine, 2, now
many
Peterborough to Cambridge rail route
100 turbines on show, delightful ride
ESCo Energy Service Companies
They supply the expensive kit
You pay the current fuel bills and kit
repayment instalments over long period
Small scale project or community maybe preclusive
If you dont ask you dont get

Liz Reason
Liz Reason of R2BC
Liz works with clients in organisations and networks to tackle the practical andemotional obstacles that get in the way of action on climate change
local charity, county and district councils on plans to set up acarbon-neutralcommunity centre at Charlburyin Oxfordshire
Having already purchased the land, with community fundraising underway andbids in for 400k,
the group was in need of expert advice on constructing an architects brief,
evidence of the benefits of low-energy design
information on full range of grants available.
HHP telephone advice,
followed by a visit to Oxfordshire to meet the group and talk through theirproposals and options
CAfE travel bursary to help pay for a visit to Hockerton to see carbon-neutralbuildings first hand.
Liz Reason
I knew that the advice was going down well
when the two architects on our committeefished out their notebooks and pens andstarted writing down the names of suppliersand costs,
At the end we had only two questions please would HHP come and supervise theconstruction of our building?
And if he didn't have the time, please couldwe clone him!
It was EXACTLY what we needed.

More recently HHP has provided advice for:
a Derbyshire community centre wishes toconsider more sustainable alternatives toconstruction and energy use,
Energy Centre in South Wales.
