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.
