The importance of ventilation in winter.

For many, the idea of having an air ventilation system on during the winter months is a strange concept. However, that is a result of thinking (wrongly) that ventilation affects the cooling of a room in some way. This is not the case and good air quality is necessary year-round, not simply during the winter months.

Winter air can be poorer quality overall, made even worse by the fact that any windows and doors are kept tightly shut-in order to preserve heat. These closed windows can have a big effect on air quality and as such ventilation remains vital even in winter in order maintain superior air quality.

Winter Deterioration.

Typically, air quality is much reduced when it comes to the colder months of the year. Fresh air is restricted due to people wanting to keep the warm air in. Which means that natural air flow is drastically reduced, leading to air stagnating. Causing a build-up of pollutants, allergens, and contamination overall.

Sealed environments both domestically and commercially help to conserve energy and save money. However, the deterioration of air quality during the winter, as a result, sees the higher rate of colds and illnesses as a result.

According to The Lancet – 800,000 people die each year due to poor air quality in the workplace. Therefore, as winter approaches, it becomes more vital to assess and implement the necessary measures for improving air quality within businesses. This is essential in order to mitigate airborne viruses and pollutants from spreading in the workplace.

Not only that but indoor air quality also plays a very important role in our health, comfort, and productivity. Good ventilation brings in fresh air, reduces air contaminants, eliminates Co2, and controls temperature and humidity.

In this article, we will discuss the importance of ventilation in winter as well as how HVAC contractors plays a role in this.

Why is Winter Indoor Air Quality Worse?

Sealing in the pollution

When it’s cold, naturally people tend to open their windows and doors less, or not at all. This is an effective method of trapping heat within a building, minimising energy consumption of drastically expensive heating systems. However, this traps dust, mould, dead skin, pollen, and other harmful airborne pollutants indoors and increases the importance of ventilation in winter. A lack of ventilation in the facilities increases air pollution levels and breathing this in will have harmful effects to each and everyone in the premises.

Over-humidifying

Cold air can’t hold much water vapour, and the colder the air, the drier it is. However, if you don’t monitor the humidity levels at your business or home, it can lead to dry skin, nose bleeds, static electricity, mould growth, dust mites and brittle furniture. Therefore, over-humidifying can not only affect a building’s infrastructure but employees’ health too. If outdoor temperatures are between 10 to 20 degrees, indoor humidity shouldn’t surpass 35%. The higher the temperature outdoors, the higher the humidity indoors should be.

More time spent indoors

Naturally, humans spend a lot more time indoors during the winter months, as we all enjoy being comfortable and warm. Humans also release a lot of carbon dioxide every day, which increases water vapour, and in the workplace/home these tiny water droplets float in the air. As water vapour level increases, the temperature of the air also gets warmer, resulting in a spike in humidity. And when humidity increases in an indoor environment, the atmosphere becomes less hygienic and more conducive to bacteria, mould, and other viruses.

Keeping Up with Maintenance of HVAC Systems.

If your team feel uncomfortable in their workplace, they’re more likely to become demotivated and unproductive. Routine maintenance of your HVAC system can help improve productivity by maintaining a comfortable temperature and reducing humidity – particularly in winter.

Most of the health risks linked to poor air quality can be lowered with the correct air conditioning maintenance and repair. Therefore, it’s good measure to implement a planned maintenance programme in order to expel indoor air pollutants and bring in fresh air instead. Congested filters in HVAC systems are futile, as they can inhibit airflow, resulting in contaminants to recirculate and build up indoors. Consequently, it’s vital that all air movement units and devices are well preserved.

At Mid-Tech Services, we can provide a service which ensures that ventilation systems are maintained at all times. Our specialist team will clean your HVAC system’s filters and coils to eliminate bacteria, as well as check the air conditioning unit is functioning properly. We will also plan scheduled checks and maintain your systems for you, making breakdowns less likely, and therefore your business running more smoothly. The importance of ventilation in winter should be a top priority for your business.

Benefits of Good Ventilation and Air Quality.

Increased Comfort

It’s without doubt that no one enjoys working or living in an uncomfortable environment. Particularly in the winter in the UK where it can get very cold as seen over the past few years, good ventilation is necessary so that you aren’t feeling the effects of the weather whilst indoors.

We spend much of our lives working inside, therefore indoor air quality and temperature must be at a comfortable level. Focusing on daily duties in the workplace becomes much easier when being able to operate in a comfortable setting where the cold air outside isn’t affecting the indoor air. Therefore, businesses must deliver a basic level of comfort through well-maintained ventilation, in order to increase morale and productivity amongst employees. Food for thought!

Increased Productivity

Colder weather means indoor air quality becomes even worse, as air pollutants trapped indoors increase. This can make staff feel sluggish, drained, and discouraged. Therefore, it becomes harder for employees to focus on workplace duties which in turn causes reduced productivity.

A YouGov study commissioned by the Building Engineering Services Association (BESA) reported that almost 70% of office employees said poor indoor air quality has a negative effect on their productivity. With staff failing to deliver their best performance, this could also begin to affect business profit. Good ventilation will mean enhanced concentration, decision making skills, job satisfaction, stamina, energy and much more. And to support this even further, a Harvard study reported a direct link between improved air quality and improved decision-making!

Maintain Health and Reduce Absences

Poor indoor air can lead to eye irritation, inflammation and breathing difficulties for some individuals. It can also exacerbate some existing health conditions e.g., asthma. In some cases, poor indoor air quality can also lead to sick building syndrome, where employees experience different symptoms when inside a building but not when they’re away from it. This makes good ventilation all the more important.

Indoor air is typically more contaminated than outdoor air, particularly in winter where viruses are rife and therefore illnesses rise. These can make your employees more vulnerable to eye and nose irritations, colds, flu, dizziness, and headaches. As a result, poor indoor air quality can cause your workforce to become sick more often, thus raising the number of absences they take. This can drastically decrease the productivity of your company and can be seriously detrimental for smaller firms already struggling to stay afloat in the current energy crisis.

You can limit the air pollutants created in the workplace by:

  • Switching to cleaning products with low VOCs (volatile organic compounds).
  • Regular deep-cleans to eliminate mould and dust.
  • Routine cleaning of HVAC unit.

Our expert team can deliver exceptional hygiene services to give your facility a thorough, deep clean, which is necessary in colder weather, where illnesses are more rampant. Our ventilation maintenance services have been designed for disinfecting, sterilisation, anti-virus, and disease prevention, as well as air purification; a one stop shop for everything you need in winter.

Manage Humidity

A further benefit of good ventilation is the ability to be able to control humidity. ERVs (energy recovery ventilation) can recapture some of the moisture in humidified air, and in turn this decreases the energy needed to humidify fresh air. Maintaining humidity levels to be between 40% to 60% can reduce mould, dust mites, fungi, bacterial growth, and viruses. Consequently, this can also prevent health problems and allergic reactions from developing. And not to mention the fact that controlling humidity levels can also maintain the safety of products, as well as the quality of stored materials and stock.
