In their recent blog, Sika explore the benefits of some simple measures that are easy to incorporate into a workplace to help promote health and well-being.
It has been estimated that staff costs, including salaries and benefits, typically account for about 90% of business operating costs. Therefore, what may appear to be a modest improvement in employee health or productivity can have a huge financial implication for employers – one that is many times larger than any other financial savings associated with an efficiently designed and operated building.
Lighting in the workplace is a key consideration and must satisfy a variety of needs. As well as allowing us to see the task in front of us, lighting can also affect many aspects of well-being, including comfort, communication, mood, health, safety and aesthetics. Poor visibility, glare, flicker and lack of control of the visual environment can all affect task performance, whilst visual discomfort may lead to headaches and eyestrain.
It is also important to note that not all colours of light have the same effect on the human body. Blue wavelengths, as exhibited by electronic screens and energy efficient lighting, are useful during daylight hours in that they boost attention, reaction times and moods, but appear to be problematic at night with a potential link to disturbed sleep patterns, diabetes and obesity.
A Room With A View
A recent study by neuroscientists suggested that office workers with windows received 173 percent more white light exposure during work hours and slept an average of 46 minutes more per night.
Workers without windows reported poorer scores than their counterparts on quality of life measures related to physical problems and vitality, as well as poorer outcomes on measures of overall sleep quality, sleep efficiency, sleep disturbances and daytime dysfunction – all of which can be classed as circadian rhythm disorders.
However, attributing these results solely to access to daylight is erroneous. Many researchers now believe that levels of exposure to white light is not the most significant factor and that in fact, views of nature and other biophilic experiences are more important. As such, biophilic research is now increasingly focusing on physiological responses such as brain activity, heart rate, blood pressure and stress hormone levels.
When used appropriately, many Sika products can contribute towards a more sustainable building design potentially leading to a more positive impact upon the building occupant’s health and well-being. For example, Sika sealants can be used to minimise the amount of window frame and maximise the amount of glazing, increasing the potential for natural lighting. Sika’s Green Roof Systems can increase the opportunities for views of nature in heavily urbanised environments.
Design in Good Air Quality
Building occupants can be exposed to a range of airborne pollutants including chemicals, micro-organisms and other particles from a variety of sources such as carpets, finishes, cleaning products, office equipment and traffic. Design strategies that ensure good air quality, both by allowing a supply of fresh air through ventilation and stopping pollutants at source by minimising emissions from materials, are essential for the development of a healthy and productive working environment.
Furthermore, the increasing availability of cost-effective wearable devices that measure CO2 levels means that design features - such as mixed-mode ventilation systems that consider thermal comfort and fresh-air requirements - will, in the future, be expected by millennials, generation Zs and top class candidates.
Design out Volatile Organic Compounds
While many volatile organic compounds (VOCs), which are emitted as gases from certain solids and liquids, are considered harmless others can adversely affect human health. Many Sika products have very low VOC content, meeting European standards such as EMICODE EC1 Plus and the requirements of BREEAM New Construction 2018. All new product creation projects at Sika have to consider all aspects of sustainability at the outset, resulting in the development of products that have been specifically designed to have lower emission levels.
Standards of the Future
Putting the focus on the end-user and their well-being is something the pioneering WELL Building Standard has done for many years. The recently released WELL v2TM pilot has expanded on this, reportedly considering buildings as “health intervention tools”. In addition, the RICS SKA rating – an environmental assessment method, benchmark and standard for non-domestic fit-outs – is also undergoing an update that is expected to return the standard to its roots by focusing on a fit-out’s impact upon the buildings occupants. The ever increasing popularity and evolution of these standards clearly confirms that the impact of building solutions on the health and well-being of building occupants is a topic that is not going to go away.
As a world class construction material manufacturer, Sika has a clear understanding that all aspects of sustainability and well-being impact each other and so can offer sustainable solutions that have a positive impact on the health, well-being and productivity of building occupants.
