Today, the impact buildings have on the environment and human health are driving innovation in building design and construction. There is a strong emphasis on supporting human health and well-being, which not only runs in tandem with reducing long-term costs but also on supporting the planet. The WELL Building Standard is at the forefront of this shift, providing a clear framework of how to incorporate and optimize green solutions to achieve key benefits for the planet and for human well-being. Improving Indoor Air Quality (IAQ) is essential to realizing these benefits.
The WELL Building Standard was designed by Delos in 2012 as the first independent standard for measuring if a building best supports the health and well-being of its occupants. Delos formally launched the WELL Building Standard in 2014 as a score-based system for both measuring and certifying a building for how it impacts human health and well-being, with factors affecting IAQ being at the center of its assessment.
Delos states that WELL “marries best practices in design and construction with evidence-based medical and scientific research”. In 2013, Delos formed the International WELL Building Institute (IWBI) to manage the WELL Building Standard.
Today, 20 million square feet of commercial, residential and institutional real-estate has been WELL Certified. According to the IWBI, 751 projects involving 141 million square feet in space in 32 countries are applying for certification under the WELL Building Standard.
Like the Leadership in Energy and Environmental Design (LEED) certification, Green Business Certification Inc. (GBCI) is responsible for administering evaluation and certification of the WELL Building Standard. The GBCI is an independent, third-party entity.
How WELL Certification Works
The WELL Certification process exclusively assesses a space’s impact on its occupants’ health and wellness, examining areas such a building’s impacts on air quality, air distribution and internal noise, among other factors. The IWBI requires the applicant to “integrate human health and well-being at the heart of building design, construction, and operations.”
The WELL Certification Process
The WELL Certification process involves five major steps:
Registration with WELL Online
Documentation Review - the WELL Assessor examines and verifies the WELL-specified design elements of the project. The applicant can choose from more than 100 potential requirements such as air distribution and others.
Performance Verification - following the Documentation Review, the WELL assessor will conduct an onsite examination following the building’s occupancy. There are three parts to this:
Granular performance tests of specific factors, such as air purity, distribution, ventilation, and quality, among others
Spot checks. Note: the onsite test will also examine building policies. For example, WELL Certification requires that the premises have a smoking ban in place (a complete reference guide for compliance can be found on the IWBI website).
WELL Certification - upon passing the Document Review and Performance Review, the GBCI and IBWI will award the building WELL Certification.
Recertification - the IWBI requires that the WELL Certified building undergo recertification every three years to ensure continued long-term adherence to the WELL Building Standard.
There are three WELL Certification levels: Silver, Gold, and Platinum, which can be had for a minimum of five, seven and nine points, respectively.
To qualify for Silver, the applicant must adhere to WELL Preconditions, and the subsequent levels are awarded based on the level of optimization and improvement in the space. Issues relating to air distribution systems, ventilation, and other air quality factors have the most precertification (12) and optimization requirements (17). Improving in these areas will have significant impacts on your occupant well-being and, in turn, your WELL score.
Getting Started with WELL Certification
Before registering with the IWBI, it’s important to determine how you intend to position your building for WELL Certification. As noted earlier, there are a total of 12 required areas and 17 opportunities for optimization in terms of IAQ, these will affect your WELL score the most.
For example, air ventilation effectiveness is a requirement, so ensuring that you use an underfloor air distribution (UFAD) system would be prudent as UFAD offers demonstrably improved air distribution, ventilation, and noise reduction. In addition to IAQ, UFAD also readily fulfills WELL requirements in occupant comfort.
Improving occupant health, especially through improved IAQ, will also enable you to accrue long-term cost-savings, not least from lower energy-usage but reduced personnel costs (such as health, medical and productivity losses) as well.
However, while aiming for WELL Certification is great, it is important to ensure that your IAQ project is properly designed and implemented, so as to guarantee that your building is truly efficient and comfortable. For example, a poorly designed UFAD system can adversely impact your IAQ, which in turn affects your score in the WELL Certification process.
