a project by
the
Whitsome Village Hall Association
to
provide a community facility
for
Whitsome Village
Whitsome ArkWhitsome Ark
to replace a war-time barrack block
transported and rebuilt as the village hall in
1952
Whitsome ArkWhitsome Ark
apart from providing suitable
accommodation, the new building had to
incorporate sustainable materials and
systems to ensure low running and
maintenance costs so future ‘managers’
would not be saddled with high expenditure
Whitsome ArkWhitsome Ark
at the design stage, the three main
‘sustainability’ components for energy
conservation were:
1. Ground Sourced Energy
2. Solar Heating
3. Building Insulation

Ground Sourced Energy
of the two methods of extraction – ‘slinkies’
(pipes buried about 1.5 metres down) and
boreholes – the likely greater consistency of
the latter made them the obvious choice
Whitsome ArkWhitsome Ark
Solar Heating
although not a source as ‘available’ as
energy from the ground, nevertheless it was
felt to be a valuable – and cheaper – addition
to the system
Whitsome ArkWhitsome Ark
Insulation
the cheapest and easiest ‘conservation’
system to install in a new building – the
Architect was instructed to ‘over insulate’ the
Ark to ensure a minimal loss of heat
Whitsome ArkWhitsome Ark
The Heating System
this comprised two sources of ‘renewable’
energy and a standby fossil fuel boiler, all
combined in an integrated system to make
best use of energy

The Heating System
at the heart of the scheme is a hot water
reservoir or ‘buffer store’ which acts as both
the collector and distributer of the heat
requirement . . .

The Heating System
the roof mounted solar panels provide heat to
a coil in the bottom of the buffer when there
is sufficient energy from the sun . . .

The Heating System
the three bore holes provide warmed brine to
the ground source heat pump which, in turn,
directly heats the water in the buffer
Whitsome ArkWhitsome Ark
brine is circulated through the bore-holes and heat pump
hot water from the heat pump can be directed to either the top of the buffer or, if the domestic hot water temperature is satisfied, the lower part

when the buffer temperature is satisfied, the
hot solar panel glycol is routed to a heat
exchanger and warms the brine returning to
the ground . . .

as the building temperature falls, demand is
made for hot water to circulate under the
floor . . .

The Equipment Room
a fairly small room was set aside to house all
the heating equipment . .

Heat Retention
without the considerable amount of
insulation built into the Ark, all the
investment in ‘green’ heating would be
wasted . . .

And More
the oil boiler serves the dual role of being
available if the ‘green’ systems cannot cope
and be the sole provider of heat when grid
electricity is lost as it can operate from a
small standby generator

The Funding – circa £48,000
the oil boiler and insulation were part of the
main contractor’s overall price but all other
equipment was paid for by grants from the
Energy Savings Trust (SCHRI), Scottish
Borders Council, Viridor (Landfill Community
Fund) and BCCF Environmental

The Future
the Ark has Planning Consent to install 10kW
of photovoltaic cells on the roof and is
seeking grant funding
a planning application has been made to
erect an anemometer mast

While we hope these simplified sketches
provide an indication of the installations at
the Ark, if you’d like to visit, all the details are
