Measurement is the key

06 October, 2023

Building operators need to balance the need for good ventilation and comfort for users, whilst minimising carbon output and energy costs, and measurement is the key to that balance. Andrew Hamshere of Sensing Precision explains how and why. 

Indoor air and the environment

The Covid-19 pandemic drew everyone’s attention to the importance of good indoor air quality (IAQ), but there is a danger that these advances in knowledge and action will be lost in the face of the energy and climate crisis. Adam Taylor of ARM Environments says we can have both. 

Indoor Air

The Building Engineering Services Association (BESA) has praised the creation of the first British Standard for health and well-being in buildings.

According to the World Health Organisation Air Pollution - both indoor and out -  is responsible for about one in every nine deaths annually and this will only get worse unless we take action to mitigate the risks. What is to be done? Sutart Smith of Zehnder has suggestions.  

Measuring Indoor Air.

Heating, ventilation, and air conditioning (HVAC) systems are crucial in maintaining indoor air quality in commercial buildings. Until recently, however, little thought has been given to monitoring the presence of airborne microbes that can profoundly impact our wellbeing. 

It's in the air we breathe

Keeping commercial and industrial environments running safely and efficiently means navigating a range of issues and dealing with threats on all scales to ‘business as usual’. Even those threats that are smaller in stature can have just as great an impact on productivity and staff wellbeing – and it doesn’t get much smaller than dust.

Nathan Wood and Rosamund Kissi-Debrah

An unprecedented combination of public outrage and government intervention is ramping up the pressure on landlords to tackle the health problems caused by poor ventilation in their buildings, according to Graeme Fox, Technical Director at the Building Engineering Services Association (BESA).

Air hygiene ratings

Despite clean air being critical to health, wellbeing and productivity, and having come out the other side of a pandemic, indoor air quality (IAQ) often remains an overlooked matter. We have food hygiene ratings - why not air? David Millward of Elta Fans has a suggestion to make.

Measurement is the key

30 August, 2022

The pandemic has set new requirements on building services to ensure the safety of building users not only from the current pandemic but future COVID variants and new viruses, says Andrew Hamshere of Sensing Precision. These new requirements not only include higher levels of airflow and ventilation to reduce infection rates, but also the ability to demonstrate these so staff and visitors can feel secure that they are protected as best they can be.

Simon Jones

Upgrading buildings’ ventilation, filtration, and other factors would not only decrease COVID transmission but also improve health and cognitive performance in general says Simon Jones of Ambisense.

IAQ guide to good practice cover

It is more than five years since the Grenfell Tower disaster; we have had a pandemic driven by an airborne virus and we are now facing a cost-of-living crisis.

Staying safe indoors

29 July, 2022

Improving air quality in our indoor spaces has never been more important. Andrew Robinson of Exi-tite explains why. 

Air distribution Filters

It is well established that efficient and effective filtration is one of the foundational pillars of any well-designed building heating, ventilating, and air conditioning (HVAC) system. David Schurk of Global Plasma Solutions and ASHRAE looks at maintaining both efficiency and effectiveness. 

Airborne Particulates

Outdoor air pollution in both cities and rural areas was estimated to have caused 4.2 million premature deaths worldwide per year based on 2016 data; with this mortality rate being attributed to exposure to fine particulate matter of 2.5 microns or less in diameter (PM2.5), which causes cardiovascular and respiratory disease and cancers. As designers and operators of building HVAC systems, we have a duty of care to make sure indoor spaces are safeguarded against the dangers posed by what is often referred to as “fresh air”, says Adam Taylor of ARM Environments.

Lines of defence

20 July, 2022

Ensuring the highest quality indoor air means designing and specifying the right ventilation system. In order to do this, however, it is important to acknowledge that each element in a HVAC system has a significant impact on its operational efficiency and quality, says James Gafford of ECEX.

Hern Yau

To date, less attention has been given to the quality of indoor air in comparison to outdoor air and pollution. According to SAGE member Professor Cath Noakes, an estimated 15% of all Covid-19 deaths can be attributed to poor air quality, meaning attention is rightly turning to indoor air as well – and ventilation is now one of the biggest challenges facing building and facilities managers today. Hern Yau of Mitsubishi Electric discusses why attention is rightly turning to indoor air quality.

Elta clean air

On Clean Air Day 2022, Elta Fans is calling on businesses to adopt best practices when it comes to indoor air quality (IAQ) management, starting with better monitoring processes.

Matt Watson of Aggreko explores how to effectively dry out sites without long-term issues.

Hern Yau

It’s fair to say that indoor air quality has been a hidden issue for many years, but the COVID-19 pandemic has put it firmly at the top of the public agenda. Hern Yau of Mitsubishi Electric speaks out. 

Daikin IAQ

Matteo Dall’Ombra, VRV Specialist, Product Management and Engineering Group at Daikin explains how by taking a whole-building approach to HVAC, it is possible to balance the drive for energy efficiency with the need to improve indoor air quality.

Social Distancing

According to Korn Ferry (a global HR consulting firm) 50% of worldwide workers are afraid to return to their offices despite social distancing practices that have been implemented, such as limiting occupancy, employee temperature scanning, face masks, special workspace accommodations and additional cleaning measures. David Schurk looks at the issues.

Digital technology has opened up significant opportunities for the reduction of energy consumption in air conditioning systems. Variable Air Volume (VAV) systems in particular have derived enormous benefit from digital control. If your current control methodology is based along traditional lines however, Ian Thomas of Trox Uk suggests there could be valuable additional energy savings waiting to be unlocked. 

IAQ Cover

It’s likely that people will be returning to offices soon so now is an ideal opportunity to address the issue of air quality inside our buildings. How can you prepare buildings for the arrival of staff, whether in co-working spaces or as the sole tenants asks Mark Grayston, Product Manager, Mitsubishi Electric.

Indoor Air Quality

The air we breathe...

17 September, 2021

The air we breathe can have a significant impact on both our physical and mental health, with Public Health England estimating that air pollution is responsible for anywhere between 28,000 and 36,000 deaths each year. This shocking statistic, combined with the fact that on average people spend 90% of their time indoors, demonstrates why indoor air quality is now a leading concern. Martin Passingham, Product Management and Training Manager at Daikin UK explains why.

Waterloo Displacement

Waterloo have strengthened their product offering by replacing their displacement range with the full portfolio of Swegon displacement products. By integrating a range of airborne products from the Swegon group, the supplier of air terminal devices can deliver the widest range of room unit products in the UK market.
