monitor the system over a period of
time, and hopefully spot any potential
problems before they cause disruption
to the occupants or staff.”
The BMS technology has site-wide
control over all heating, cooling,
ventilation, hot water, room window
blinds, automated roof lights, storm
pumps, foul water pumps and
metering. As a result, staff can monitor
and make changes to all the
associated equipment from a single
system.
Remote access
“The BMS can be accessed remotely,
enabling staff to adjust and monitor the
site from home,” says Mr Burton. “It
also allows me to access the system
away from site if any issues occur that
may require my input.”
Although there are no energy-saving
figures available to date, Mr Burton
concludes by stating that the desired
outcomes have been achieved.
Furthermore, maintenance savings are
expected as preventative maintenance
routines can be utilised by interrogating
the BMS data.
“Touch screens are fitted at locations
that are accessible to staff, allowing
them to inspect the system locally.”
Priva Blue ID S10 controls are used in
four controls panels, with the new
Priva Blue ID C4 controls deployed in
the other three. The Priva Blue ID Sline is designed for projects that
require the maximum flexibility,
extension options and uptime, while
the C-line is a more compact and
versatile option that is more suitable
for smaller control panels within
medium-sized projects.
“At Clayfields House, I used Blue ID
C4 controllers at locations that didn’t
require a large amount of I/O as this
allowed significant cost and space
savings for the client,” says Mr Burton.
“Priva TC History is also active on the
system to enable the collection of
temperature, metering and plant data,”
explains Mr Burton. “This software

Fan coil units (FCUs) were selected to
provide heating and cooling to every
room independently. Heat recovery
units work with the FCUs to save as
much energy as possible. The Priva
BMS controllers communicate to the
FCUs and condensers over the
network via BacNet, which has
enabled extremely precise control.
Moreover, this configuration served to
minimise the amount of I/O and
electrical installation work required.
