Breathing easier

02 July, 2018

As concern grows over rising traffic air pollution levels, authorities are responding urgently to the pressing need for action to protect people, especially those in cities. But what can building services professionals do to help? Peter Dyment explains.

Heat recovery, Lee Caulfield, mechanical ventilation, MVHR, Titon

Ventilation is an essential part of modern properties, yet on many occasions this vital component isn’t considered until late in the construction process. Lee Caulfield looks at the importance of MVHR systems being considered as early as possible during a building’s design.

Airing the issues

05 July, 2017

There is much debate on trends in natural ventilation, but is it all hot air? Roy Jones of Gilberts of Blackpool shares some thoughts.

Airflow Developments, ventilation, MVHR, IAQ, Indoor air quality

In a recent report from the Building Engineering Services Association, almost 70% of office workers believed poor air quality was having a negative effect on their wellbeing and productivity. Robert Dennis of Airflow Developments highlights the importance of effective ventilation in commercial buildings to create and maintain a healthy and energy efficient environment.

Xpelair, MVHR, IAQ, Indoor air quality

Xpelair’s Natural Air 180 MVHR (natural ventilation with heat recovery) units come with a vast choice of add-ons designed to make them suitable for virtually all domestic ventilation requirements. One feature is the option of NOx filtration via an external box.

SAV, ventilation, IAQ, Indoor air quality

SAV AirMaster MVHR (mechanical ventilation with heat recovery) units have enable Furze Down School in Winslow, Bucks, to control indoor air quality efficiently while maintaining the low noise levels required for special educational needs. This co-educational community school takes children from the ages of five through to 19, many of the with complex special educational needs (SEN).

Condair, humidity, RH, relative humidity, IAQ, Indoor air quality

Tim Scott of Condair asks why 40 to 60%RH is the ‘ideal’ indoor relative-humidity level.

Bio-Oxygen Europe, odours, IAQ, Indoor air quality

Bio-Oxygen Europe has been set up to bring the Australian-produced Bio-Oxygen system for eliminating odours, sterilising and purifying air to the European market. The system is said to guarantee odour-free results, along with 99% elimination of viruses and bacteria. It is compact as has low maintenance requirements.

Indoor air quality (IAQ) is the quickest and cheapest way to protect people from worsening air pollution, according to one of the country’s foremost clean-air campaigners. Speaking at a special IAQ event to mark the UK’s first ‘National clean air day’ last month, Simon Birkett, founder of Clean Air in London, said that IAQ must become part of the building planning process.

Condair, dehumidifier, IAQ, Indoor air quality

Condair has introduced a range of advanced commercial and industrial dehumidifiers. They cover desiccant and condensing technologies with extensive standard capacities from 0.5 to 182 kg/h (at 20°C/60% RH). Custom units are also available.

Vent-Axia, MVHR, IAQ, Indoor air quality

The energy-efficiency features of Vent-Axia’s Sentinel Kinetic Advance MVHR (mechanical ventilation with heat recovery) have led it to winning a major award — the energy-efficient product or innovation of the year category of the CIBSE Building Performance Awards for 2017.

The BB101 guide for ventilation in schools is being updated. Roy Jones of Gilberts (Blackpool) looks at its implications.

Ruskin Air Management, ventilation, jet nozzle, Indoor air quality, IAQ

Discreet but effective ventilation is a key part of the design for the St John Bosco Arts College in Liverpool, which won last year’s RIBA North West Award. The original idea was to use floor-standing displacement ventilation terminals for this massive ‘hangar’-style open-plan facility, but the architect, BDP, felt they would be too intrusive. A second proposal involved multiple jet nozzles to ventilate the space, but BDP was concerned about their unsightly appearance. The team then turned to Ruskin Air Management’s Jason Laugharne, who proposed slot diffusers.

Airflow Developments, MVHR, heat recovery, Indoor air quality, IAQ

In response to the challenges of ventilation for commercial buildings, Robert Dennis of Airflow Developments looks at the key issues to consider and the innovative solutions that can save valuable time, energy and costs — whilst creating a healthy interior environment.

Envirovent, duct, ducting, Indoor air quality, IAQ

Ventilation manufacturer Envirovent has launched a range of semi-rigid ducting which is quick to install and airtight. The Fast Track range is available in circular and flat-oval form and in various sizes. There are three sizes of duct for domestic and small non-domestic systems. All ductwork can be connected to a universal distribution box using adapters.

Gilberts, natural ventilation, Indoor air quallity, IAQ

Gilberts (Blackpool) offers a solution to maximise the benefits of natural ventilation in rooms such as IT suites and science laboratories in schools. Particular issues in such areas include heat from IT equipment and CO2 from Bunsen burners. Gilberts’ solution is its Mistrale Fusion (MFS) natural-ventilation system with the inclusion of enhanced and boost options.

Weatherite Air Conditioning, data centre, Indoor air quality, IAQ

Airbox from Weatherite Air Conditioning is an air-containment solution that provides an energy-efficient addition to airflow management for data centres. It provides an effective way of helping to control airflow in data centres, server rooms and communications rooms.

Nuaire, demand controlled ventilation, Indoor air quality, IAQ

Are some approaches to demand-controlled ventilation so complex that they are not effective in reducing overall cost and carbon footprint. Andrew Bott of Nuaire shares his views.

Towards low-energy IAQ

01 July, 2015

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.

Indoor air quality, Camfil, air filter, air filtration

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.

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.

Indoor air quality, Gilberts of Blackpool, natural ventilation

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.

Indoor air quality, LG, Air conditioning, aroma

Air conditioning delivers a quality indoor environment, and that quality can extend to indoor air quality — as Jody Lees of LG explains.
