News from the Group

We now have over 250 members signed up to the CHP Group in just six months
making it the fastest growing special interest group in CIBSE, ever! Tell all your friends
(including non CIBSE members) to sign-up by visiting the web site. www.cibse.org/chp

Successful inaugural event

Over 90 delegates attended the CHP Group’s first event held at Balham early this year.
The conference on “CHP in Buildings – The State of Play” provided an overview of
where CHP currently stands as a viable building service, where it might be going, and
which technologies might take it there. With a wide range of papers from some expert
speakers, the event gave an opportunity for debate that has been sadly lacking in
recent years. The proceedings of the conference should be available on the CHP group
web site in the next few weeks www.cibse.org/chp.

Date set for major event - Community Heating Networks

The CHP Group is organising a major event on Community Heating Networks on
October 19th. This will include speakers covering the international scene, the design
and installation of community energy networks plus case studies including the Woking
borough Council CHP/fuel cell community energy network and Edinburgh University
heat network. Go to www.cibse.org/events or contact Jennie Sinfield at CIBSE on 020
8675 5211 to book a place.

CHPA Responds to government strategy

The CHPA didn’t pull any punches when responding to the governments strategy on
CHP. While the CHPA welcomed the governments recommitment to “….continue to
aim at our target of 10 GWe of Good Quality CHP capacity in the UK by 2010” it
described the strategy as “A Triumph of Hope over Reality?” The CHPA says that “at
best only 8.5 GWe will be achieved and there is no attempt to say how this policy gap
will be plugged.” It said “the government has failed to set out a firm action plan with the
industry to implement the CHP strategy in order to stimulate recovery in the CHP
sector. Today, the Government’s CHP policy remains a catalogue of missed
opportunities.” www.chpa.co.uk

Largest ever grant allocation for community heating

Over £16m grant funding has just been allocated for thirteen eco-friendly, community
heating projects owned by local authorities, housing associations and universities
across the country. This is the largest ever government funding round awarded for
projects of this kind to date. Since the scheme’s inception in 2001, nearly £44 million of
the Government funding has been allocated for CHP and renewables community
energy projects. Due to this increased demand, it is unlikely that further bidding rounds
will be held until a government announcement, expected in the autumn. Schemes
supported by the Community Energy programme in 2002-04 have assisted more than
53,500 people on low incomes, generating 47MW of CHP and are saving nearly 23,500
tonnes of carbon per annum. www.est.org.uk/communityenergy

Report on community heating potential

A recent DEFRA-funded report, “The Potential for Community Heating in the UK”,
outlines heat demand across the UK and calculates the potential for community heating
schemes using CHP. It found that community heating could deliver savings on fuel bills
to more than 5 million UK homes, 200 hospitals, 750 schools and 80 universities
www.est.org.uk/communityenergy/ukpotential/heatmaps.cfm.

Micro CHP is growing rapidly

Since their first installation in October 2002, Baxi now have 35 units across 29 sites
either being installed or in operation. Most are run on natural gas with some fired on oil.
They generally supply small community energy schemes in multi-tenanted
accommodation (e.g. sheltered housing) ranging from 14 to 300 dwellings. Two units
running on light fuel oil in Northern Ireland supply energy to NHS Trust nursing homes.
There are now over 8,000 of these units installed across Europe and this is expected to
rise to 10,000 units by the end of 2004. www.baxitech.co.uk

Cogeneration Company add to their range

To supplement their existing range of natural gas engines (90 kWe –2 MWe), the
Cogeneration Company, formerly Nedalo UK Ltd, has added new ranges that can be
run on LPG (75-960 kWe), landfill (83-320 kWe) and biogas (85-1,000 kWe). This
provides more opportunity to install CHP across a wider range of industries and should
help to expand the use of renewable fuels with CHP. www.cogenco.co.uk

First domestic fuel cell trial

In the first trial of its kind, a fuel cell developed by Smart Energy Ltd is being trialed in a
test house at BRE’s Watford site. The energy Minister Stephen Timms launched the
field trial saying “my department will keep a close eye on progress as we have a big
stake in its success.” In this trial, funded by the Carbon Trust, an alkaline fuel cell CHP
system (with lead acid battery energy storage) is supplying electricity to a full-scale test
house that mimics the requirements of a real home with a range of simulated
occupancy patterns, Heat produced by the unit will augment the house's gas fired
central heating system. Fuel cells can be fired on natural gas but the fuel cell unit being
trialed will be fuelled with compressed hydrogen supplied by Air Products Ltd. For more

CIBSE Carbon 60 competition includes micro CHP

A team from Fulcrum Consulting has won the CIBSE Carbon 60 competition. The aim
of the competition was to find the best way of reducing carbon emissions by 60% from
CIBSE’s Balham headquarters buildings in South London. The winning entry tackles
demand, supply and monitoring in order to achieve the carbon reductions. Proposals
range from simple improvements in the building fabric to external shading and replacing
CRT monitors with LCD flat screen technology. More complex measures include the
possible installation of a 5 kWe micro-chp unit. The Carbon 60 Competition challenged
contestants to come up with a realistic scheme to convert the Institution’s buildings (a
converted Victorian mansion and a 1980s purpose-built conference centre) into a low-
carbon set of buildings. Specifically, to reduce carbon emissions of the buildings by
60%. www.cibse.org/carbon

DVLA get CHP-absorption licence

Ener-G has completed the installation of a tri-generation energy system for the Driver
Vehicle and Licensing Agency (DVLA) in Swansea. The system has the capacity to
reduce the DVLA’s CO2 emissions by over 3,000 tonnes per year. This supplies six
administrative buildings, including the 17 storey landmark D block building. Employing
around 5,000 staff at its 23 acre site on the outskirts of Swansea, the DVLA holds the
details of nearly 40,000,000 driver and 30,000,000 vehicle licences. Ener-G has
provided a 1MW CHP unit and a 700 kW absorption chiller to complement the existing
three 1.2 MW electrical chillers. This enables high utilisation of the CHP heat output

during warm periods when the cooling demand is high. The scheme is financed by
Ener-G with investment recovered via the company’s Discount Energy Purchase
scheme. www.energ.co.uk

New Action Energy software

Action energy has launched an updated software tool, CHP Sizer Version 2 for sizing
CHP covering hospitals, hotels, university halls of residences and leisure centres. The
software has been developed using actual energy profiling data collected from the four
building sectors. The programme takes users through five steps: entering the building
parameters; examining the thermal and electrical demand profiles; integration of CHP
with the building services; entering electricity and fuel tariffs; interpreting the results
including cost savings. Action Energy have also produced GPG388 – CHP for buildings
that provides a valuable introduction to the subject including case studies and a simple
example of a feasibility study. Both are available free from www.actionenergy.org.uk

Energy Bill includes micro CHP

The Energy Bill has now received Royal Assent to become the Energy Act. Part 2,
Chapter 1 of the Act covers Renewable Energy Sources and also includes micro CHP.
It makes provisions in relation to electricity produced by generating stations producing a
heating or cooling effect in association with electricity. The Act also requires publication
and implementation of a strategy with targets on micro-generation (anything <50kWe)
with the emphasis on very micro CHP, small scale renewables, fuels cells, and ground
source heat. www.legislation.hmso.gov.uk/acts/acts2004

Part L consultation published

The consultation document on Part L of the Building Regulations has been published,
comments and submissions need to be in by 22nd October. In amongst the 300 page
document are some significant steps forward for CHP. The proposed Part L is now split
into four documents, here are a few relevant quotes:

     ADL1A Domestic New Build

     “The new edition of SAP will include allowances for the quantification of non-
     repeating thermal bridges and the impact of electric lighting on the carbon
     emissions from a dwelling. New systems such as microCHP will also be included.”

     ADL1B Domestic - Work in Existing Buildings

     “Where a boiler is to be replaced by a microCHP appliance, reasonable provision
     for an energy efficient space heating system would be to install an appliance with
     an efficiency not less than that recommended for its type in Guidance Document
     [which is in the process of being prepared by BRE]”.

     ADL2A Non Domestic - New Build

     “Improve the energy efficiency of the envelope, HVAC and lighting systems so as
     to achieve a reduction in “demand” CO2 emissions of 20% AND provide
     renewable energy or low carbon systems such as CHP to reduce “supply”
     emissions by another 10%. This is required by Article 5 of the EPBD and is the



                                            4/5                                 CIBSE CHP Group
      means by which ADL2A encourages building integrated renewables or low
      carbon strategies like CHP.”

      “In order to determine the carbon dioxide burden of the building, the carbon
      dioxide emission factors below should be used.

            Table 1: Carbon dioxide emission factors                                   (kgCO2/kWh)
              Grid supplied electricity (note 1)                                       0.422
              Grid displaced electricity (note 2)                                      0.568
              Waste heat                                                               0.018

            Note 1: this is the value to use for all electricity consumed in the building
            Note 2: this is the value to be used when crediting any on-site generation system”


      ADL2B Non Domestic - Work in Existing Buildings

      “Where a boiler, or existing CHP plant, is to be replaced by new CHP plant,
      reasonable provision for the heating system efficiency would be a system certified
      under the CHPQA……..”

welcome comments on all aspects of the Part L consultation document either directly to
Samantha McDonough smcdonough@cibse.org or via the CIBSE Website discussion
forum.

Powergen expands into micro CHP

Powergen has placed an order for 80,000 micro Combined Heat and Power (mCHP)
units over the next five years in a new business move into the home energy services
market. The ‘WhisperGen’ unit is expected to cut household energy bills by £150/yr and
has been successfully launched in the East Midlands, East Anglia, Yorkshire and North
West regions, with 400 units due to be installed by July 2005. Powergen Home Energy
Services is planning to offer WhisperGen nationally in 2005 at a total installed cost of
£3,000 which is around £500-600 more than a conventional boiler installation, with a
typical payback period of around four years. Additional savings can also be made by
selling surplus electricity back to Powergen. Powergen is also offering customers an
optional five year interest free credit finance plan. Contact Powergen on (0800 107
1366) (whispergen@powergen.co.uk) or see www.whispergen.com.
