Be relaxed about building services design<br />
Much of the complexity of<br />
designing, installing and<br />
maintaining central heating in<br />
multi-occupancy low-rise<br />
buildings can potentially now<br />
be eliminated.<br />
Gilberts have created a roomby-room<br />
solution that<br />
combines appropriate<br />
ventilation with heat boost.<br />
This means that in effect, there<br />
is no need to provide radiators<br />
in the rooms in which the new option is fitted. Further, because the<br />
solution is fitted at ceiling height, it liberates interior design and<br />
optimises use of floor space.<br />
The solution focuses around Gilberts’ unique Mistrale Fusion unit<br />
with an integrated LPHW coil. Just 2 x standard MFS128 (one at<br />
either end of the room), or 1 x MFS256, will ventilate, and, warm, a<br />
standard classroom to all Regulatory requirements re air quality.<br />
“The energy cost of running the unit for morning warm-up has<br />
been calculated at just £2.19/annum/room(*),” says Gilberts<br />
Technical Director Roy Jones. “And there’s all the initial capital<br />
savings attained from the purchase and installation of a central<br />
heating system, with all the radiators, ductwork, thermostats. MFS<br />
heat coil delivers a win-win strategy.”<br />
The stand-alone unit is installed as normal through the building<br />
façade. The core MFS appliance provides natural ventilation and<br />
uniquely blends the incoming fresh air with the warmth from the<br />
exhaust air without the need for a heat exchanger.<br />

The Water Regulations Solution Specialist<br />
Natural ventilation with enhanced thermal efficiency<br />
Passivent, the natural ventilation specialist, has improved the<br />
performance of its Aircool® ventilators. As a result of recent<br />
product improvements, thermal performance has increased by<br />
22%, giving specifiers greater flexibility to meet the energy efficiency<br />
demands of a building. Achieving U-values as low as 0.86W/m2K, the<br />
ventilator offers excellent performance when closed.<br />
The range of controllable insulated ventilators has been designed for use<br />
in external facades, including all forms of wall construction, curtain<br />
walling and window profiles. The ventilator includes integral electrically<br />
actuated, modulating dampers which control the air intake and extract.<br />
Being low voltage, the dampers are energy efficient and they are also<br />
virtually silent in operation. The Aircool’s thermally broken frame design<br />
minimises the risk of condensation. Weather protection and security are<br />
provided by the external weather louvre, even when the internal<br />
insulated louvre is open. The ventilators can also be supplied in modular<br />
form for maximum flexibility; acoustic and thermal options are also available.<br />
“The thermal upgrade makes Aircool one of the best in its class. It’s the ideal partner for<br />
BREEAM projects,” said Passivent’s Design Manager James Hammick. “With wall sleeves and<br />
external weather louvres provided as standard, it’s also straightforward to contractors to<br />
install,” he continued.<br />
The ventilator can be used across a range of markets including education and commercial.<br />
As well as being suitable for daytime cooling, it can also be used for night cooling to reduce<br />
the risk of overheating. Being fully automatic, there is no risk of the Aircool overcooling.<br />
Passivent offers a comprehensive technical design service including assistance with product<br />
selection, system design and early stage thermal modelling.<br />
