Air-conditioning is about more than temperature

A significant proportion of the work we undertake here at Holborn, is the design, installation and maintenance of precision air conditioning systems. These not only regulate humidity and temperature, down to the last tenth of a degree, but filter particulates out of the air too.

Particulate matter in the air is receiving a lot of attention at the moment, with more than half of the UK population believing air pollution levels are damaging to their health. Almost two-thirds back proposals for laws encapsulated in a new Clean Air Act to tackle the issue.

This focus on improving air quality is understandable, given that London Mayor Sadiq Khan condemns the capital’s air as toxic and claims more than 9,000 premature deaths across London can be attributed to air pollution.

Whilst images relating to the story typically show people outside walking around in a smog-laden atmosphere, there is growing concern about the impact of external pollution on indoor air quality.

Despite the abundance of air conditioning in larger shop and office complexes, for most people opening a window remains the favoured method of ventilation – in the mistaken belief they are introducing ‘fresh air’ into the building.

Regulations to stem emissions will be a good thing, but as we have witnessed with climate change legislation, it can take a long time for the benefits to become evident on the street. I suspect, protecting people from airborne pollutants, when they are inside buildings, where most people spend more than 80% of their time, will achieve more in a shorter time.

The latest heating, ventilation and air-conditioning (HVAC) systems, from manufacturers like Toshiba and Mitsubishi now feature remarkably good filtration systems, designed to prevent outdoor pollutants from entering internal spaces.

There are even additional ultraviolet-based systems that take the concept one step further to disinfect the circulating air. But for those buildings that already benefit from air-conditioning, ensuring systems are working properly, with incoming air filtered and cleaned effectively would have a significant impact on the health and well-being of people.

A survey in 2016 by the Building Engineering Services Association found almost three-quarters of office workers believed poor air quality in their place of work was negatively impacting their day-to-day productivity and wellbeing. Almost a third believed their health was at risk too.

Combining high quality air-conditioning and effective filtration of incoming supply air with improved air-tightness for buildings will significantly reduce the amount of particulate matter circulating within the building.

The impact of high temperatures within the workplace, on the health and productivity of individuals is well known, but perhaps now the focus should shift to air quality.

In recent years air conditioning systems have become increasingly energy efficient to help combat climate change, but now the role modern systems can play in protecting building occupants against rising air pollution should be recognised.

Solving the draughts from your air-conditioning

As a business Holborn Projects, works largely with close control air-conditioning and cooling for large data centres, where the maintenance of a predictable, cool temperature is all that matters. Draughts are largely irrelevant. However, when we work on commercial air conditioning systems, typically keeping office environments a bearable 15-16 degrees in summer, draughts can be…

Server

Server room air-conditioning upgrade on drawing board

We didn’t make a big fuss when our new website went live and we filled it with lots of interesting relevant content, but thanks to Google, we recently received an enquiry from a someone that searched for ‘server room air conditioning’. Fortunately, it’s not just something we do, but something we do well and on…

Airflow-containment

Designing an airflow containment system

Whether its higher energy costs or increasing energy consumption driving the switch to well-designed airflow containment systems, a range of benefits over the open, more traditional data centre designs are on offer. Amongst the advantages offered by an effective airflow containment strategy, is that by preventing the hot air and cold air mixing the cooling…

What to look for when hiring an HVAC contractor?

I recently had a long conversation on the phone with an angry and frustrated project manager working for a construction company. Not because of anything we’d done wrong, but in the hope we might be able to help. It turns out, one of our customers had recommended us to a construction company that needed immediate…

Employment opportunities – but is anyone listening

As a business, I’m glad to report Holborn Projects is doing well, with plenty of work for our core skills of close-control air conditioning and our less well-known power upgrade work. As with many aspects of engineering, we spend a lot of time scoping, specifying, pricing and planning work, before we arrive on site with…

Electric-car

Rise of the electric car

In recent weeks, there’s been lots of focus in the news about tackling air quality issues, and what measures we must put into place to achieve clean air zones in certain parts of the UK. With new reports highlighting the need to reduce pollution levels, particularly in cities, the spotlight is on Diesel-powered vehicles and…

Why your office needs air conditioning (part 2)

In our last blog we looked at the law on temperatures for working environments, thermal comfort and the productivity boost offered by an office deemed comfortable for the majority of workers. Now we’ll look in more depth at a few ways the installation of a new heating, ventilation and cooling (HVAC) system will benefit your employees and…

Why your office needs air conditioning (part 1)

The well-being of employees is becoming ever more important as organisations strive for productivity and efficiency improvements, without impacting the work-life balance. The office environment is receiving increasing attention, with care given to seating, lighting, opening hours, access to break-out areas, fruit, water and even happiness managers. But what about the temperature? While installing air…

Heatwave

Is your air-conditioning ready for this summer’s heatwave?

Although the British summer has been its usual unpredictable self, it appears we might be in for a sustained hot spell, with Mediterranean temperatures promised in the weeks ahead. It’s great for families on holiday or anyone with access to their own pool, but for workers across the country, it will probably create an uncomfortable office environment,…
