tempered as it is drawn into the interior space, there are no cold spots or draughts, optimising occupant comfort. Most systems can be tailored to individual specification by the inclusion of LPHW heat coils, connected to heat pumps and additional filtration. It is even possible to run on 100% fresh air, using the optional heat coil to temper the incoming air temperature. This keeps a cleaner and safer environment while ensuring indoor temperatures are not compromised, thereby avoiding cold draughts without the need to boost heating systems to maintain internal comfort levels. Using the heat coil also eliminates the need for radiators, which optimises usable floor space.
It is now possible to virtually test any design before installation, to ensure appropriate levels of ventilation
Filtering the options for IAQ
Specifi ers can tailor-make their internal environments using an innovative approach to ventilation devised by Gilberts (Blackpool) Limited. The air movement specialist has developed a range of modular ‘accessory’ boxes to integrate with its innovative hybrid Mistrale Fusion System (MFS) stand-alone ventilation. The concept enables easy addition of various fi ltration options, to the MFS through- wall or through-window unit. Thus, just by adding the appropriate box behind the core Fusion unit, the ventilation can be simply and effi ciently adapted to the specifi c requirements of each room, be it F2-7 rated inclusive, or F7+NOx fi lters. “Using this modular approach makes it as simple as possible for the precise needs of each room to be met, including compliance with the latest requirements regarding Covid,” explains Gilberts’ Technical Director Roy Jones. “For example, one facade may overlook a busy road, so require greater fi ltration of emissions from diesel and other pollutants. Specifi cation of the appropriate fi ltration box to the individual MFS unit means those needs can be met, without complicated ducting, wiring or building management systems.”

PR.indd 1 AET’s sustainable answer
What is sustainability? Well, that’s the question we should all be looking to answer, right? For years developers have been progressing their projects using tried and tested methods, but those methods are now being put under the spotlight. Why? Because in most cases, these methods of building have been proven to be unsustainable. Many commercial offi ce buildings are designed with ceiling-based air conditioning systems but are they truly sustainable? For changing occupiers, moving pre-fi tted systems, and adding additional duct work is often required, resulting in an expendable amount of waste. AET Flexible Space offer a very simple answer to this problem, as we do not require the same duct or pipework required by ceiling based systems. AET systems use the fl oor void as a plenum and are inherently fl exible. This means developers can fi t out the building at CAT-A stage safe in the knowledge that when the new tenants take ownership they can re confi gure the existing equipment easily and effectively in a matter of minutes. In a nutshell, AET’s underfl oor air conditioning system is the sustainable option.

Even if mechanical ventilation is used in office space, a little careful thought in the design of the way the air is delivered into – and exhausted from – the interior can optimise use and flexibility of floor space. Linear bar grilles located around the perimeter, swirl diffusers in an exposed ceiling or raised floor are some examples. Coinciding with Covid, but driven by the need to reduce energy consumption and cost (running at around £0.5bn per year), HTM guidance in the healthcare sector was updated to require natural ventilation to be
the default, with mechanical ventilation as a last resort.
In such environments, the air movement paths need to be different, particularly in operating theatres where the air needs to “wash” over the patient on the table and flow away at low level to effectively remove airborne pollutants or particulates. Software modelling is crucial to validate any design in such a sensitive environment. Schools too are also an increase in building, and the latest Building Bulletin 101 guidance recommends hybrid ventilation as the most appropriate solution to balance IAQ and sustainability. The trick for architects, going forward, is to work with experts such as building services consultants, and, ideally manufacturers. Working to balance such complexities on a daily basis, they have the in-depth knowledge to guide specifiers. Architects and other consultants can then be sure that the systems are as energy-efficient and environmentally friendly in all aspects as they can be. The desired aesthetic can still be delivered, but with the appropriate quality of internal air and comfort.
