HEVAC president Mike Nankivell highlights the importance of filters to indoor air quality and why IAQ should be considered alongside energy efficiency.

Indoor air quality, IAQ, Munters, desiccant dehumidifier

The refurbishment of three Munters desiccant dehumidifiers at Manchester Aquatics Centre has reduced running costs by about 20%, while preserving the building fabric and optimising comfort. The project involved replacing all major components, replacing the old reactivation ductwork with polypropylene and retrofitting the dehumidifers with Munters energy-recovery purge technology to reduce running costs.

Daikin Europe’s VAM and VKM heat-recovery ventilation units include CO2 sensors and optional filters to reduce energy lost and maintain high air quality in commercial premises. They are quick and easy to install and also offer night-time free cooling when part of a complete climate solution.

Health-driven IAQ

01 December, 2013

With poor indoor air quality being estimated to cost two million healthy life years annually throughout Europe alone, Alan Macklin of Elta takes a look at the HealthVent project.

Indoor air quality, IAQ, Vortice, fan

Vortice twin fans (pictured) and acoustic box fans are designed to run so quietly that they are suited to applications such as museums and libraries. General manager Kevin Hippey says, ‘These void-mounted products offer a new opportunity for specifiers working in environments where combating noise is particularly important.’

Indoor air quality, IAQ, Matrix, fan coil unit

Ability Projects has developed a 190 mm-deep Matrix self-balancing fan-coil unit to complement the current 270 and 235 mm-deep units. Matrix units have internal-rotor-motor fans and motor sets with every fan directly coupled to its own motor, making every fan/motor assembly an independent entity and enabling its speed to be individually controlled.

Indoor air quality, IAQ, Aeereco, demand controlled ventilation, heat recovery

Aereco’s DXR demand-controlled MVHR (mechanical ventilation with heat recovery) system for homes controls both the supply and exhaust air streams. It is claimed to achieve 92% energy savings compared with a mechanical exhaust ventilation (MEV) system at constant airflow, while providing the same indoor air quality.

Nearly half the British workforce (46%) have suffered headaches, tiredness and felt less productive because of stale air and stuffy working environments — according to research conducted by Populus for Guardian Air Hygiene. Of the 1082 workers surveyed, 38% believe that the quality of air in workplaces is an indicator of employers’ attitudes to employees’ wellbeing.

Indoor air quality, IAQ, Xpelair, ventilation, school

Guidance on ventilation in education is provided by Xpelair Ventilation Solutions’ CPD training programme. It is designed to help specifiers and installers better understand the changing ventilation requirements and legislation in the education sector.

Indoor air quality, IAQ, WindowMaster, natural ventilation, school

WindowMaster has produced a ‘white paper’ for contractors on how best to ensure that natural-ventilation systems in new schools meet the criteria for the Priority School Building Programme. It can be downloaded from the link below (case sensitive).

Indoor air quality, IAQ, Elta Fans, centrifugal fan, duct

The Viper SCC range of duct-mounted centrifugal fans is part of Elta Fans’ Select range and can produce high pressure even with low air volumes. The fan is well suited for installation in sports and leisure facilities, schools, colleges, retail centres, factories and similar duct-mounted installations. These fans have been designed with the requirements of the ErP Directive, which came into force on 1 January 2013, in mind.

Indoor air quality, IAQ, Gilberts, swirl diffuser

Gilberts’ Series GB range of barrel-type swirl diffusers provides a wider range of architectural and design style swirl-diffuser options that combine aesthetics with cost-effective alternative design. These diffusers have a fixed-size square fascia designed to fit plaster ceilings and standard 500 or 600 mm-square ceiling grids.

Indoor air quality, IAQ, Mitsubishi Electric, MVHR, heat recovery

If a building’s occupants do not feel healthy and happy then they cannot be productive, so getting the indoor air quality right is an important step to delivering a ‘good’ building. Perry Jackson of Mitsubishi Electric looks at how effective mechanical heat recovery ventilation can help both the wellbeing of occupants and overall building efficiency.

Warming to natural ventilation

01 December, 2013

One of the challenges of natural ventilation is reducing the expense of tempering cold draughts in winter. Shaun Fitzgerald of Breathing Buildings takes up the subject.
