INDOOR AIR QUALITY Online tool to determine IAQ
IACONNECTS has introduced a free online tool to help businesses evaluate their indoor air quality (IAQ). This tool consists of nine questions that take approximately five minutes to complete. It addresses various aspects of air quality, including regulatory compliance, health impacts, and current monitoring capabilities. Upon completion, users receive a score ranging from 0 to 100 per cent, indicating their potential to enhance their IAQ monitoring practices. The higher the percentage, the greater the opportunity for the user to improve. Research indicates that poor air
quality in commercial settings can lead to a reduction in productivity by up
BUILDING MANAGER
IoT-based system delivers operational efficiency
An intelligent building manager called WEOZ has been launched by LEGRAND, designed to support building and facility managers. WEOZ has been
developed to provide an alternative to a traditional building management system. A user-friendly IoT ecosystem that centres around a network of area managers, it offers the ability to combine all the functions a building needs to achieve energy efficiency – such as lighting control, air quality and metering. The solution is suited
for small and medium spaces, particularly multi- site businesses, including offices, schools and
32
retail sites. It is not only operationally efficient but is also designed with occupant well-being front-of-mind. Crucially, WEOZ offers building managers real- time understanding of occupancy levels in their buildings, with the ability to adjust room ambience accordingly. For retailers, this information provides the added benefit of footfall analysis. WEOZ creates a
network of connected multi-protocol area managers using edge data and rules management. This affordable and efficient solution is compatible with a number of Legrand’s energy efficiency solutions, including Light Up sensors, and EMDX3 metering, as well as third party systems, including
Airzone HVAC controls. ■

VENTILATION
Improving heat recovery
The VRC ventilation system range has been launched by STIEBEL ELTRON to improve heat recovery in residential and light commercial buildings. This system can achieve up to 92% heat recovery, contributing to better heat retention in homes. The VRC range represents the company’s return to the centralised Mechanical Ventilation with Heat Recovery (MVHR) market, complementing its existing decentralised systems. The VRC units are equipped with
features for both winter and summer use, including a heat exchanger bypass mode that promotes cooler indoor
temperatures during warmer months. The Enthalpy models include active moisture control to help manage indoor humidity and mitigate the risk of damp and mould. Designed for spaces up to 425m2, the system allows for flexible installation, with a detachable control panel that can be positioned 20m away. The VRC system is Wi-Fi enabled, letting users control ventilation settings via a mobile app. The app can also integrate with the company’s heat pumps, allowing for streamlined management of both systems. Its lightweight casing simplifies installation, with the units requiring minimal maintenance, as no tools are needed for servicing, and optional filter upgrades are available to reduce
allergens and pollutants. ■

New from ATLAS COPCO is an industrial fluid cooler designed to deliver optimal cooling efficiency and flexibility while reducing environmental impacts. The TDV 01-06 series combines the energy-saving benefits of a dry fluid cooler with enhanced thermal efficiency provided by an adiabatic system. This offers customers a flexible and energy efficient means of achieving optimal temperature regulation while enhancing the overall efficiency and performance of water-cooled equipment. The TDV 01-06 A/AD series is suitable for cooling single or multiple water-cooled equipment and uses ambient air to effectively cool the water circuit and ensure that the desired temperature is consistently maintained. It includes an adiabatic option that can achieve water temperatures lower than the ambient air temperature using the evaporative properties of adiabatic pads. There is no process water
consumption and no water spray in the air stream or on the coils, eliminating water stagnation and Legionella risk. The cooler features an automated
control system that adjusts fan speed and pad humidification, switching between dry and adiabatic modes to optimise energy and water use. Constructed from galvanised steel with powder coating, the unit is resistant to corrosion and includes removable panels for inspection. The design facilitates integration with existing cooling systems, allowing for tailored configurations based on specific site
conditions. ■
