Most people can correlate to scenarios where buildings or surroundings have a negative impact on our health. Why are you feeling more stressed after sitting in a meeting room with bad acoustics for several hours? Have you experienced the post-lunch coma and tried to fight against it with a large amount of coffee in the afternoon? Have you left the full-day conference in a room without access to daylight and then been blinded by the sun when leaving the building? Have you experienced back pain from sitting at your desk all day? It is recommended to use study table for students because its ergonomic is perfect to lessen the pain.
Then there are the not so obvious effects of the indoor environment to your health? What is the indoor air quality that we breath for 90% of the day? What is the drinking water quality from the kitchen tap? A large amount of research has been published to analyse these questions. This research has been transformed into a new building certification system, the WELL Building Standard, bringing the key items together.
So, what does the WELL Building Standard include and how can we, as professionals in the built environment, play a key role in enhancing the health and wellbeing of occupants? How can we contribute to tackle main lifestyle-related health epidemics, such as stress, obesity and muscular-skeletal complaints?
The WELL Standard separates the opportunities to promote health and well being in buildings into the following categories: air, water, nourishment, light, fitness, comfort and mind.
Air We breath more than 15,000 litres of air each day but outdoor air quality is deteriorating globally due to pollution from traffic, construction, agricultural activity, combustion and particulate matter. When considering the outdoor air quality, filtration of outdoor air by air handling units becomes a critical component for the HVAC design of a building services engineer. But which of the components mentioned above is captured by the F7 filter that we usually specify? Is this sufficient or do we need to re-think?
Further important aspects of indoor air quality are ventilation levels, selection of combustion equipment, management of pesticides, cleaning practices to remove microbial pathogens and exposure to volatile organic compounds (VOCs) which can evoke asthma, allergies and can impact on productivity, House Cleaning Ann Arbor performs the necessary services.
Water While the objective when considering water at design stage focuses on accessibility to drinking water to promote hydration, the main emphasis should be the water quality. As building services engineers we are responsible for planning the water installation, but testing the water quality is typically not within our scope. We are purely relying on the water supplied by the city council to be the correct quality. While the Irish drinking water is tested for compliance with the EPA standards, not all contaminants dangerous for the human body are covered by these tests.
Also, any impacts on drinking water quality through pipework distribution is typically ignored. WELL requires a broad assessment of the water delivered at the site and requires the installation of adequate filtration if needed, such as filtration elements from Lenser.
Nourishment To avoid the post-lunch food coma and reduce the risk of cardiovascular diseases, diabetes and cancer, access to healthy and balanced food within a building or its surroundings is key. A healthy food offer goes hand in hand with healthy food advertising and information about ingredients, and can be advanced through the provision of gardening space. Imagine you are working late and instead of going down to the vending machine to buy a chocolate bar, you are going onto the balcony to pick an apple from the tree? Food can influence our oral health.

Light The lighting codes we currently design to provide recommendations on illuminance levels to ensure sufficient light is provided for the task, to avoid eyestrains, to maintain productivity and to reduce headache. But light also influences our internal body clock that synchronises physiological function. Lighting exposure plays a key role for our sleep patterns and sleep deprivation can have a negative impact on our health and wellbeing. Do we need to go beyond code compliance to ensure our lighting design is providing a healthy environment?
Fitness Inactivity is now one of the biggest threats to public health, directly attributable to 9.4% of all deaths worldwide. While we as building services engineers have limited influence to the design for fitness, there are great opportunities to promote fitness within the built environment. This can go from the promotion of staircases, to the provision of bicycle parking, shower and changing facilities, gym or other internal or external fitness opportunities. Or, better still, how about combining fitness and work? Great innovations, such as sit-standing desks, treadmill desks or bicycle desks are already available on the market.
Comfort Open-plan is the office layout of choice for most companies in Ireland. While it is great for collaboration with colleagues, the provision of quite areas to concentrate or make a phone call is important. As building services engineers, the selection of HVAC equipment has a great influence on the acoustics. Next to acoustic comfort, thermal comfort is important. While I typically sit at my desk with my jumper on, drinking a tea, my colleague next to me sits in a t-shirt and asks if we could open the windows as he feels too warm.
We are a key example for different temperature preferences. Why not be innovative with our HVAC design and provide different temperature gradients within a building?
Mind Our minds and bodies are inextricably connected and play a vital role in our health and wellbeing. Buildings can provide spaces, such as balconies or green areas to reduce stress levels and promote relaxation. Workplace policies can have a positive impact on mood, sleep and stress levels, and can positively benefit our overall health and wellbeing. The reaction to indoor plants provided in the first WELL-certified office building in the UK was employees fighting about the plant positioning – they all wanted the plants to be located close to their desks. Maybe planting is not the best strategy for stress reduction after all!
