Hebden Bridge Town Hall
The Client
Hebden Bridge Town Hall is a listed building that has
undergone a major refurbishment including a 2 storey extension to
provide facilities for small business start up units including
conference and meeting facilities. The scheme has been funded by
investments from the Community Builders fund and the European
Regional Development Fund.
The Challenge
Part of the funding for the project was dependant upon
the building achieving a BREEAM "Very Good" rating. Also the
planning consent stipulates 15% of the energy consumption must be
provided from low or zero carbon technologies. The M&E
installation is critical in achieving this requirement.
The Solution
To meet the planning consent of 15% energy from low or
zero carbon sources on site, a trio of technologies had to be
employed.
The majority of the 15% is achieved via a CHP that is capable of
delivering 30kW of heat and 17kW of electricity. The heat energy is
used to provide heating and hot water. Acting as the lead heat
source the CHP is supported by 2 No. 115kW condensing boilers for
generating low temperature hot water.
In addition 12m2 of solar thermal panels have been installed to
help meet the hot water demand.
To ensure that 15% renewable energy is generated onsite, 24m2 of
solar PV panels have also been installed. Both the CHP and the PV
have been configured to export any unused electrical energy to the
national grid.
Ventilation to the conference and meeting room facilities is
provided by air handling units equipped with high efficiency
exhaust air heat recovery heat pumps.
SBEC Building, TATA STEEL
The Client
The SBEC (Sustainable Building Envelope Centre) in
Deeside is a pioneering partnership between the Low Carbon Research
Institute, TATA Steel and the Welsh Assembly that will test,
monitor and evaluate various low carbon technologies in different
combinations to help inform specification decisions for both new
build and refurbishment projects.
The three-year research project has been designed to investigate
the next generation of low carbon whole building solutions to help
create a blueprint for the most effective use of renewable energy
technologies.
The Challenge
The building comprises various office spaces and
facilities located across the ground, first and second floors. The
heating and cooling to these areas is to be provided via a
combination of sources, a full building energy management system is
required to ensure the most efficient use of these energy sources.
The Transpired Solar Collector also delivers energy as a primary
heat source which has to be factored into the overall operation of
the building services.
The Solution
Kimpton was responsible for designing and installing the
VRF system, hot water services, rain water harvesting, gas fired
heating system and the full BEMS network as part of the energy
efficient installation.
The facilities on the three floors are heated and cooled by a
Mitsubishi VRF heat pump system and the Transpired Solar Collector
(TSC) is used to temper the incoming air.
For the VRF system Kimpton installed four air handling units
complete with DX refrigeration coils, which have been integrated
into the VRF system. An additional VRF system has been provided to
heat/cool the meeting rooms and circulation areas via fan coil
units, along with a Mitsubishi Heat Pump Boiler to provide under
floor heating with water at 45°C flow temperature.
The hot water system features a Stiebel Eltron hot water heat
pump that utilises air from within the room and extracts the
thermal latent energy which the heat pump uses to warm the water in
the cylinder.
The SBEC test bay is provided with warm air in the winter months
via a gas fired air heating system connected to a network of ducts.
Surplus heat from the TSC is used to warm this air before the gas
is used, thus helping to reduce the consumption of natural gas.
Kimpton also installed a Rainwater Harvesting system to provide
water to the staff and visitor toilets.
Harlow Carr
The Client
The £3.3 million Bramall Learning Centre at the Royal
Horticultural Society's (RHS) Harlow Carr gardens will provide free
education facilities to more than 10,000 children each year. The
building has been designed to reflect environmental sustainability
and biodiversity in every element and has already achieved the
highest BREEAM score ever awarded for a public bespoke
building.
The Challenge
As a popular visitor attraction, the Bramall Learning Centre's
energy demands for power and heating are high and a key objective
is to meet all energy needs from a range of renewable sources
including a ground source heat pump.
As part of this new build project, Kimpton was appointed to
provide the heating, passive cooling, ventilation and plumbing
services.
The Solution
The ground source heat pump installed by Kimpton will provide the
low grade heat to cater for the thermal comfort requirements of the
occupants delivered via an underfloor heating system.
Such is the groundbreaking use of renewable energy built in to
the building's design, including the ground source heat pump
installed by Kimpton, all of its energy needs will be met from
renewable sources and it is also expected to feed power back into
the national grid, saving the production of 75 tonnes of carbon
dioxide each year.
Commented a spokesperson from the Bramhall Learning Centre:
"Indications to date are that the equipment installed by Kimpton
will rise to the challenge and help the building to achieve carbon
neutral status with all of the energy coming from renewable
sources.
Hopton Mills
The Client
Hopton Mill in Mirfield near Huddersfield began manufacturing
cloth in 1790 and by 1815 was exporting to America. The mill
buildings have remained in commercial use ever since and their
current owner is currently investing in a £multi-million
refurbishment of the site to create a contemporary, sustainable
office park in a rural setting.
The Challenge
The first building on the complex to gain a complete face lift was
'The Watermill', a 3,000m2 , two-storey former mill building. Main
contractor, NU Construction, is responsible for delivering the
transformation, with Kimpton Renewables contracted to design and
install the development's heating, comfort cooling, ventilation and
plumbing services.
The Solution
It was the existing water abstraction bore hole used in the
building's former textile production processes that provided the
key to Kimpton's ingenious approach to eco-friendly comfort
cooling.
With the water extraction license renewed, Kimpton were able to
refurbish the bore hole and engineered a solution that will both
safeguard the local water table and provide reliable cooling for
the building.
Kimpton's expertise was essential in this complex project which
required accurate calculation, control and treatment of the water
flow and discharge rates in order to ensure that there was no
effect on the local water table and that acceptable levels of
cooling were maintained. The bore hole refurbishment and
integration with the cooling system were part of a wider mechanical
installation by Kimpton, which also included installation of a gas
fired low pressure hot water system, decorative panel radiators and
occupancy ventilation for the deep plan areas.
Shibden Park
The Client
Shibden Hall and Park are located near Halifax in Yorkshire,
they date back to 1420. It became a public park in the 1920s when
it was donated to the people of Halifax.
The Challenge
As part of a mulit-million pound restoration project of the
historic Hall & Park, a new learning centre called Shibden
Mereside, was to be built to house a café and a range of versatile
function rooms.
Kimpton were contracted to provide the heating, ventilation and
plumbing services to the new-build and the refurbishment of the
outbuildings throughout the park.
The Solution
Heating throughout the building is sourced from the low grade
energy source of gournd loop 'slinkies' buried in the banking to
the rear of the building which are interconnected to a Dimplex
Fighter 24 water to water heat pump. The heat pump increases the
water temperature for both heating and hot water purposes,
circulating heating water temperature at 43°C to serve 3 underfloor
heating manifolds with loops closely centred at 75cm.
The building benefits from an all glazed east facing elevation
to allow the sun to assist with the heating of the building in the
morning and a Trend Control System to open and close high level
windows and low level vents to promote natural ventilation for
thermal comfort during the summer.
Wellington Business Park
The Client
Built by the Langtree Group, Wellington Business Park consists
of high specification office premises and is located in
Newton-le-Willows.
The Challenge
To achieve maximum energy efficiency and minimum carbon
emissions for the offices, the implementation of a series of
environmentally friendly measures were necessary, including the
heating and cooling system.
The Solution
Kimpton Building Services was responsible for the design, supply
and installation of the heating and cooling system to the 2-storey
office block that will be fuelled by a ground source closed loop
heat pump.
The ground source closed loop heat pump works by collecting heat
from the ground and transferring it to the Park's HVAC system for
use in heating the offices.
The park will be able to reduce its carbon emissions and energy
consumption by as much as 70% thanks to the ground source heat
pump.
Ground source water systems are one of the recognised renewable
energy sources listed as part of the Government's push for 10%
renewable energy usage.
