Gilberts for Aesthetic Refurbishment?
art of a 1970s office building is
being taken into the 21st
century with a sustainable
alteration to its ventilation strategy.
Facilities management expert Apleona
HSG, on behalf of Royal Sun Alliance
(RSA), is executing a phased
refurbishment of three floors of the 11
storey block. An integral element of the
upgrade is updating the core systems to
Consultant Ernest Griffiths had to
balance integration of the new strategy
with the practicalities of suspended
ceilings and large glazed areas, so
turned to leading independent air
movement specialist Gilberts Blackpool
to assist.
As a result, Kimptons Energy Solutions
has installed some 270no of Gilberts
GSFH fixed swirl diffusers into the
ceiling, sited behind perforated tiles,
balanced with LN linear bar grilles along
the window cills and underneath the
bulkhead of the large glazed areas, NV3
door transfer grilles and, in the toilets,
DGA4 extract vents.
“The project involved remodelling the
existing ventilation system, to create
something that was more efficient: the
existing had been refurbished in part
over the years, with some areas being
integrated, and some stand-alone. The
most efficient solution was to create a
new unified solution, with new grilles and
new variable air volume boxes,”
explained Kimptons Chris Tolley.
Added Ross MacGugan of Ernest
Griffiths, “Gilberts’ grilles and diffusers
were the most suitable technically and
aesthetically for the project. The
company’s technical team visited to
assist with the design and specification.
We know from many similar projects
Gilberts’ technical data can be trusted
and is reliable.”
Gilberts GSF diffuser, a patented
design, uses radial vanes behind a
perforated face to allow the introduction
of high levels of air horizontally across
the ceiling with rapid entrainment and
The LN linear bar grilles have bars fitted
flush with the flange face, angled at
Capital Building to 15degrees to ensure
airflow without draughts. Gilberts’ NV3
door transfer grilles allow Regulatory
flow of fresh air whilst being vision proof.
The DGA4 vents in the toilets feature a
louvred face for a horizontal air pattern.
