  • Six Basic Factors of Thermal Discomfort

    4th September 2015

    Our last post covered why thermal comfort is important in the workplace, this post goes into more detail about the six basic factors of thermal comfort.

    Firstly lets start with some interesting facts.

    Fact: Thermal discomfort caused by air conditioning is the UK Building Research Establishment’s biggest climate control complaint.
    Fact: 74% of British workers argue with colleagues over air conditioning.
    Fact: 72% of British workers feel their office never gets the temperature right, making them feel uncomfortable, cold and unproductive.

    The HSE states thermal comfort should be measured in ‘six basic factors’ which can either be independent of each other, or combine to create thermal discomfort. They are broken down into environmental factors and personal factors.

    Environmental factors: Simply put, environmental factors are things that affect the indoor environment you are in. They include the following:

    Air temperature – The temperature of the air surrounding your body.

    Radiant temperature – Thermal radiation is the heat that radiates from a warm object; radiators, electric fires, furnaces, ovens, cookers, dryers, machinery, the sun, etc.

    Air velocity -One of the most important factors in relation to thermal comfort because people are sensitive to air movement patterns. Air velocity is the speed at which air moves across a person e.g. cooler air moving at a faster rate may cool a worker down, while still, heated air may make people feel stuffy. Equally important is the fact that air causes draughts – if the air temperature is less than skin temperature, it will increase heat loss through the skin, even when the system is in heat mode.

    Humidity – Relative humidity is the ratio between the actual amount of water vapour in the air and the maximum amount of water vapour that the air can hold at that air temperature. The more relative humidity in the air (i.e. the higher the ratio), the harder it is to sweat as humidity prevents the evaporation of sweat from the skin.

    Personal factors:These are factors which are individual to you:

    Clothing insulation – Thermal comfort is directly affected by the clothes you wear. Clothing interferes with our ability to lose heat to the environment. Wearing too much clothing or PPE will make you too hot, wearing clothing with inadequate insulation in colder temperatures will make you too cold. Therefore clothing can both cause and control thermal comfort.

    Work rate/metabolic heat – The more physical work you do, the more heat you produce – those in physical jobs may be more likely to experience heat stress than those who have sedentary, office based roles. In addition, factors such as your weight, size, age, fitness level and sex can all have an impact on how hot or cold you personally feel.

    Adapting to avoid thermal discomfort

    Where possible, employees should be allowed to adapt their situation to the thermal environment:

    Putting on / taking off layers of clothing
    Moving away / towards heating or cooling sources
    Moving away from draughts

    However, this may not always be possible – invariably people will work in an environment which is a product of their job e.g. the receptionist will work in an environment where the door constantly opens and closes leaving them exposed to the outside elements. The GP will work in a reasonably small room, mostly static at their desk, with room temperatures higher than you would expect in an office environment (they also have to deal with airborne viruses and bacteria). Office layout will also affect people’s abilities to move to hotter or colder areas of the building, or move away from draughts.

    So what can you do about it? Contact Airius and a member of the team will be happy to discuss your thermal comfort with you in more detail.

  • The Importance of Thermal Comfort

    3rd September 2015

    What is Thermal Comfort and Why is it Important?

    Most people are aware that employers have a duty of care towards their employees, but how many people realise this extends to creating a comfortable indoor environment, without draughts and hot or cold spots? BS EN 7730 and the Workplace Regulations both emphasise the importance of keeping staff comfortable; in this article we explore what this means in relation to your working environment.

    Firstly we need to deal with the rather dry subject of regulations. Don’t worry I’ll keep this brief as there are two key points you need to keep in mind:

    Workplace (Health, Safety and Welfare) Regulations 1992, Approved Code of Practice (ACOP), point 50:

    Workers should not be exposed to uncomfortable draughts. In the case of mechanical ventilation systems, it may be necessary to control the direction or velocity of air flow.

    Workstations should be re-sited or screened if necessary.

    BS EN 7730:

    Thermal comfort is defined in British Standard BS EN ISO 7730 as:‘That condition of mind which expresses satisfaction with the thermal environment.’

    Thermal comfort is not about measuring room temperature, although it does relate to whether a person feels hot or cold. Thermal comfort takes in a range of environmental and personal aspects and is worked out by the number of employees complaining of being uncomfortably hot or cold.

    Why is BS EN 7730 the ACOP so important?

    If you are in a draught, you are cold, you are unproductive and you are unhappy. In a nutshell, thermal comfort keeps people happy. It keeps workers comfortable and most importantly for business, it keeps staff productive. It also keeps workplaces safe.The HSE website states:

    People working in uncomfortably hot and cold environments are more likely to behave unsafely because their ability to make decisions and/or perform manual tasks deteriorates. For example;
    people may take short cuts to get out of cold environments,
    or workers might not wear personal protective equipment (PPE) properly in hot environments, increasing the risks,
    or the workers’ ability to concentrate on a given task may start to drop off and increases the risk of errors occurring.

    As an employer you should be aware of these risks and make sure the underlying reasons for these behaviours are understood and taken into account. Addressing the underlying reasons for these behaviours is also likely to improve morale and productivity as well as improving health and safety.

    Although the above safety aspects may seemingly apply in the construction industry or a more industrial environment, a walk around most offices in the UK will reveal that thermal comfort makes a big difference to productivity: Thermal comfort with traditional heating, ventilating and air conditioning (HVAC) systems is hard to achieve. The staff member sitting underneath the air conditioning unit in summer will invariably have the layers piled on, while shivering in the cold blast of icy air, while those on the periphery of the air con unit sweat in the heat. In winter, have a count up of the number of desk heaters in use where staff are complaining of cold feet, or staff members wearing scarves while sitting at their desks.

    The HSE states 80% of occupants is a reasonable limit for the minimum number of people who should be thermally comfortable in an environment. However this means that 20% of the workforce is in discomfort and not working to their full ability. Remember then that most buildings won’t even hit this 80% comfort level.

    So now you know why thermal comfort is important, what can you do about it? Contact Airius to find out the award winning solution they provide and how it could benefit you and a member of the team would be pleased to discuss your application.
