The building services profession has long moved from pipe, ductwork and equipment sizing to a much broader and more complex role. Topics like sustainability, energy savings, renewable energy and BIM (building information modelling), just to name a few, have become a huge part of building services design, sales, manufacturing and construction. Renewable energy, for example, has been brought back to the top of our priority list through the recent release of Building Regulations Part L 2017 (NZEB), and sustainability rating systems such as BREEAM, LEED and the Home Performance Index are part and parcel of our daily jobs.
A new topic has recently entered the Irish market – building design and operation that focuses on the benefit of health and well-being of people. This “second wave of sustainability” is focused on providing the optimal working environments where people can thrive and fulfil their highest potential.
Why is this important? There are multiple ways we, as building services professionals, can positively impact the health and well-being of people in buildings through our design and construction practices. Here are a few aspects to consider.
A ventilation system, designed and built for optimal indoor air quality, has the potential to reduce the negative effects attributed to asthma, headaches, hay fever and the flu. Recent studies have also shown that improved indoor air quality has the potential to enhance individual cognition by up to 61%.1 Attention to detail when selecting materials such as paints, ductwork sealants, glues, ceiling tiles, carpets and furniture can reduce the toxic off gassing within the first year of installation and with that, potentially reduce the risk of cancer.
Another aspect is the design of water systems. Legionella has been the key word in the design and construction of water systems within the last 20 years. While this is still an important topic that cannot be neglected, the design of water systems should also take other harmful contaminants into account. This can be done by installing a whole house filtration system. Project-based water quality testing and the design of a consequent filtration system that removes all contaminants and optimises the testing of drinking water, should become part of our scope in the future. Providing employees with access to high-quality and good-tasting drinking water has shown to positively influence hydration and therefore concentration levels.
The lighting environment we design for the people inside our buildings, who spend 90% of their time indoors, can impact their visual, circadian and mental health. Presently, most spaces are fitted with lighting systems that meet the visual needs of individuals, but do not consider the effects of lighting on our internal body clock or mental health. Research and design provides huge opportunities in this area.
A building’s indoor thermal environment not only affects its energy use, but also influences the health, well-being and productivity of the people inside. Thermal comfort is ranked as one of the highest contributing factors that influence our satisfaction with our buildings. While designs typically meet thermal comfort standards on paper, there is limited on-site verification to ensure that the space actually performs as intended.
As landlords and tenants alike increasingly demand healthy workspaces, we would do well to shift the focus towards on-site performance testing when it comes to these design and construction practices. Certification programmes such as the WELL Building Standard™ (WELL™) already require testing for air and water quality, thermal and acoustic comfort, as well as lighting levels, propelling the industry to integrate this practice into the commissioning process and the day-to-day working lives of building services professionals, as for maintaining the building in good conditions, you can find building maintenance companies in York PA that really help with this issues.
Companies have already started to investigate the financial value of health and well-being interventions. A recent study by the World Green Building Council outlines The Business Case for Health and Well-being in Green Building. The published study features Cundall’s London office at One Carter Lane, which has claimed £200,000 annual savings based on reduced absenteeism and staff turnover.2 This office is the first space to be WELL Certified™ in Europe and has seen huge benefits by focusing on human-centred design, construction and operations.
Arup’s office in Cork, the first WELL Certified™ space in Ireland, has also generated significant interest in healthy office environments. IPUT’s headquarters at St. Stephen’s Green, Dublin is on track to become the first WELL Certified™ office in the capital.
With these and other exciting developments, building services professionals are now faced with their most important role … supporting the health of the people who use their buildings every day.
