plant for hire


F


ollowing a lull during the pandemic, plant hire is becoming an important alternative for businesses looking to


replace existing HVAC equipment. As budgets come under pressure In times of rising energy costs, political and economic uncertainty, there are obvious benefits to going rental – a traditional alternative to capital investment. In particular there are new opportunities


where equipment allows commercial businesses to look at heating and cooling in the same equation. The benefits range from cost, flexibility,


environmental impact, immediacy, right down to 24/7 maintenance – all important considerations for the modern business. In November HVR puts this spotlight on


rental equipment and this month both ICS Cool Energy (pg 13) and Carrier Rental (pg 14) explore the advantages. There two other standout features this month – on pg 20 Baxi’s Jeff House explores the role of hydrogen in the decarbonisation of heat; and on pg 26 Groupe Atlantic’s Charlie Mowbray explores the role of heat networks on the path to Net Zero. * Finally, look out for this month’s picture special (Pgs 16-19) from the glittering HVR Awards ceremony held on September 29.

Cutting edge heat & vent W


ith new agile working, more and more offices are being refitted. The latest data reveals in central London alone, more than


70% of office construction is refurbishment. Gilberts Blackpool has a pioneering ventilation solution, that optimises sustainable natural resources and cuts energy consumption. It has the added benefit of optimising useable floor space, and removing the need for suspended ceilings or exposed building services thus delivering an uncluttered working environment aesthetic. The MFS stand-alone, hybrid ventilation solution is essentially a natural ventilation unit that can operate solely on fresh air. It includes a quiet, low energy fan to supplement airflow only as conditions demand. Installed through the external façade or window (or


the rooftop), the MFS mixes ‘used’ internal and fresh external air to ventilate the internal space providing free cooling with heat recovery and no risk of cross contamination.


A mixing damper within modulates airflow


to allow the new, fresh air to mix with the warm exhaust air, thus extracting its heat without the need for an exchanger. The integrated low energy fan energises to blend the internal air, ensuring an even distribution of airflow, controlling CO2 levels without stratification. The smart Mistrale Control Unit (MCU) gives individual, automatic room control, requiring no occupier input to maintain the comfort levels within. Each MFS unit can be accessorised with an LPHW


coil to temper the air to provide Covid compliant ventilation without compromising the internal temperature, or filter boxes to control NOX and other pollutants (F2-7 or F7+). Integrated into the heating system – including heat pumps – the MFS can utilise the warmth generated from LPHW systems to warm or cool the internal space as needed without the need for radiators and all associated ancillary capital costs. Free night cooling is standard; a boost mode enables the air within the space to be “purged” for


fast redress of air quality and temperature As a solus ventilation unit, MFS costs as little as


£5/room/year to operate. Using it as the means of room heating adds just £2.19/room/year. Its sustainable credentials are further enhanced by its design: the MFS range attains air leakage better than legislative requirements – 5m3/HR/m2, and a U value of 1W/m2/°C. It delivers efficient weather performance via its bespoke louvre system (up to Class A). MFS has also been engineered to minimise embodied carbon MFS has already been proven to help achieve BREEAM Excellent, contributing points towards Energy and Health & Wellbeing. From a design perspective, being at high level


through the external façade, MFS airs the internal space without the need for a suspended ceiling to conceal ductwork. It enables high level architectural features to be


exposed and highlighted without the intrusion of exposed ventilation systems. Its location through the façade and entrainment process also eliminates draughts and cold spots. By using the MFS for heating there is no need for


radiators, further freeing utilisation of the internal space and provision of clean, uncluttered aesthetics. MFS is cost effective to install, requiring no ductwork. Being primarily natural ventilation, it is attractive to potential occupiers from sustainability and operational cost perspectives. It maximises their use of the floor plan. This combination helps reduce churn rates. Ian Rogers, Gilberts’ sales director, said: “MFS helps simplify the complex issues architects are facing in todays’ fast-paced office design environment. In one unit, it delivers a highly cost- efficient, sustainable option, that liberates design of the internal space, from floor to ceiling, creating an internal environment that enhances the health & wellbeing- and therefore productivity- of staff.”
