David Hunt Eco Environments Ltd

• Are you ready for the Carbon Crunch?
• 26th March 2009

Who we are

• Eco Environments are Double MCS accredited
  installers of solar and wind power, we also
  install solar thermal, air source heat pumps,
  rainwater harvesting, and energy efficient
  lighting.
• We are based in Bootle and service the
  construction and property sectors for new build
  and refurbishment of commercial and residential
  schemes across the Northwest.

What is MCS?

• The Microgeneration Certification Scheme (MCS)
  is owned by the department for Business,
  Enterprise and Regulatory Reform (BERR formerly
  DTI) and is designed to evaluate products and
  installers against robust criteria for
  microgeneration technologies, providing greater
  protection for consumers and ensuring that the
  Government's (i.e. taxpayers) grant money is
  spent in an effective manner - BERR

The Code for Sustainable Homes

• The Code for Sustainable Homes has been developed
  to enable a step change in sustainable building
  practice for new homes
• The Code is intended as a single national
  standard to guide industry in the design and
  construction of sustainable homes.
• It is a means of driving continuous improvement,
  greater innovation and exemplary achievement in
  sustainable home building.
• The Code measures the sustainability of a home
  against design categories, rating the whole
  home as a complete package.
• Design categories included within the Code are
• energy/CO2 materials
• pollution waste
• Water surface water run off
• Management health wellbeing

The Code for Sustainable Homes

• The Code uses a sustainability rating system
  indicated by stars, to communicate the overall
  sustainability performance of a home. A home can
  achieve a sustainability rating from one (?) to
  six (??????) stars depending on the extent to
  which it has achieved Code standards
• The code also offers Regulatory certainty, the
  levels of performance for energy efficiency
  indicate the future direction of building
  regulations, bringing greater regulatory
  certainty for home builders.
• Lower running costs, homes built to Code
  standard will have lower running costs through
  greater energy and water efficiency than homes
  not built to the Code standard.

The Code for Sustainable Homes

• From May 1st 2008 all new homes must be assessed
• A route map has been laid out detailing the key
  dates for compliance.

Solar Photovoltaics (PV)
Solar panels work on daylight, rather than
sunlight, though do perform better, the more sun
there is. Solar PV is very simple to integrate
into the household electricity supply. You must
notify the DNO when connecting to the grid,
beforehand if your system is of a reasonable
size. Grid systems export surplus electricity to
the grid, for which you are paid.
8
Solar Photovoltaics (PV)
Solar panels come in two types. Solar tiles,
which are particularly suitable for new build
domestic properties. Social Housing are starting
to use these a great deal. Although this is
scheme by house builder Gleeson. The tiles are
simple to fit by a roofer, but needs to be
designed, installed and commissioned by an
accredited installer.
9
Solar Photovoltaics (PV)
Solar panels Come in a range of power outputs
and can be put into different sized arrays
depending on the output required. Solar panels
generate DC electricity which is goes through an
inverter to become AC before connecting directly
to the property supply. Solar panels need to be
on a south facing, or predominantly south facing
roof to have real value.

Wind Turbines
Probably not so relevant for the early stages of
the code, but much better suited to power small
developments, say 3-4 houses. Wind isnt
generally suited to highly urban areas
though. But for commercial, industrial and
agricultural developments they are superbly
productive. A 6kw turbine producing on average
16,000 kwh per annum, creating revenue as well as
powering the development.

Solar Thermal
SOLARFLAIR
How does it work? For domestic hot water there
are three main components -Solar panels or
collectors - are fitted to your roof. They
collect heat from the sun's radiation. There are
2 main types of collector Flat plate systems -
which are comprised of an absorber plate with a
transparent cover to collect the sun's heat, or
Evacuated tube systems - which are comprised of
a row of glass tubes that each contain an
absorber plate feeding into a manifold which
transports the heated fluid. A heat transfer
system - uses the collected heat to heat water
Hot water cylinder - stores the hot water that
is heated during the day and supplies it for use
later.

The benefits Solar water heating can provide a
home with about a third of its hot water needs.
The average domestic system reduces C0 2 by
around 325kg per year and about 75 a year of
your hot water bills, when installed in a gas
heated home.
These savings are approximate and are based on
the hot water heating requirements of a 3 bed
semi detached home.

Heat Pumps

• A heat pump is mover of heat, a
  
  system that absorbs energy in one
  
  place and releases it in another.
• They use an inexhaustible, free
  
  and sustainable energy source
• They offer high levels of energy
  
  efficiency leading to reduced CO2
  
  emissions and energy bills
• They are able to provide space heating, hot water
  heating and even cooling if required
• They now offer a real alternative to traditional
  fossil fuel based systems such as gas oil fired
  boilers

14
Heat Pumps The benefits

• Renewable technology
• Inexhaustible supply of renewable energy
• Energy efficient 300 to 400
• Low carbon emissions
• 50 lower than conventional heating systems
• Lower running costs than conventional heating
  systems
• Increased efficiency reduced consumption
  lower bills
• Provides 100 of heating hot water demand
• No reliance on fossil fuels
• No annual safety checks
• Single source utility

Combined Harvesters
Rainwater Harvesting
Water consumption and surface water run off are
significant parts of the Code for Sustainable
homes and critical to achieving the standard.
For example, the first stage of the code, level
three, it is a mandatory requirement that mains
water consumption be reduced to 105 litres per
person per day.
16
Combined Harvesters
Rainwater Harvesting
Rainwater is captured from the roof(s), and
brought to a central point, via normal guttering
and down-pipes, to enter a storage tank
(frequently underground), where it is filtered on
entry. A highly efficient and reliable
submersible pump delivers the water to a service
on demand. Where wished, or a special reason
applies, delivery can be to a normal header tank
instead.
