Air conditioning delivers a quality indoor environment, and that quality can extend to indoor air quality — as Jody Lees of LG explains.
Gilberts’ natural ventilation is a high performer
Gilberts of Blackpool’s Mistrale 75 ventilation units achieve accurate and stable airflow and also have low air leakage and good thermal performance. Air leakage is as low as 5 m3/h.m2, with a U-value of 0.93 W/m2K, similar to a double-glazed window.
To help protect and improve indoor air quality in new homes, BEAMA has launched the ‘Health home mark’ campaign. It calls for support of a ‘Healthy home mark’ in all new homes to enable buyers to identify that its has been fitted with effectively installed continuous mechanical ventilation.
Camfil’s energy-efficient range of air filters
Camfil’s Hi-Flo II air filter is an enhanced version of the Hi-Flo low-energy air filters. Aerodynamic pockets optimise performance, and these filters have been rated A+ by Eurovent. They save up to £30 a year for every installed filter.
Achieving good indoor air quality (IAQ) in buildings can be expensive in terms of energy consumption. David Black of Flakt Woods examines how that cost can be minimised.
Balancing quality with efficiency — the importance of IAQ
HEVAC president Mike Nankivell highlights the importance of filters to indoor air quality and why IAQ should be considered alongside energy efficiency.
Manchester Aquatics Centre cuts the cost of dehumidification
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.
Heat-recovery ventilation units from Daikin
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.
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.
Vortice fans are very quietly in operation
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.’
Ability Projects Matrix fan-coil unit is just 190 mm deep
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.
Demand-controlled ventilation with heat recovery from Aereco
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.
Survey highlights poor 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.
CPD covers ventilation in education
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.
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).
Elta Fans introduces duct-mounted centrifugal fan
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.
Barrel-type swirl diffusers from Gilberts
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.
Productive buildings that are also energy efficient
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.
Airflow adds to range of residential MVHR units
Airflow has introduced a new range of basic MVHR (mechanical ventilation with heat recovery) units for residential housing. Tunca Sekban, MVHR product manager, says, ‘MVHR in residential dwellings is becoming increasingly common, and units such our new BV range make this type of ventilation a much more realistic option for developers and social housing providers. The low running costs and high efficiency ratings mean payback times are significantly lower than several years ago when MVHR first came to the fore for ventilation.’
Warming to natural ventilation
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.
Delivering good indoor air quality cost effectively
Good indoor air quality is essential in commercial applications to maintain productivity and comfort. Andy Cardy of Fläkt Woods, looks at how building-services engineers can optimise working environments while reducing energy costs.
