Well Building Institute
The International WELL Building Institute (IWBI) is leading the global movement to transform our buildings and communities in ways that help people thrive. IWBI delivers the cutting-edge WELL Building Standard, the first to be focused exclusively on the ways that buildings, and everything in them, can improve our comfort, drive better choices, and generally enhance, not compromise, our health and wellness.
WELL is premised on a holistic view of health: human health as not only a state of being free of disease - which is indeed a fundamental component of health - but also of the enjoyment of productive lives from which we derive happiness and satisfaction. Healthy spaces protect us from that which can make us sick, promote practices that can keep us well, and facilitate opportunities for us to connect with one another and live our lives to the fullest.

WELL operates on a points-based system, with a total of 110 points available to each project. Projects must achieve all preconditions as well as a certain number of points to earn different levels of certification:
WELL Silver Certification: 50 points
WELL Gold Certification: 60 points
WELL Platinum Certification: 80 points
Projects must earn a minimum of two points per concept. Projects may earn no more than 12 points per concept. At the point of submitting for Documentation Review, projects may submit a scorecard that contains up to 100 points worth of features. Projects can also add on an additional ten points for Innovation to their scorecard.

|---|---|---|
| T01 Thermal Performance | Ensure that the majority of building users find the thermal environment acceptable. | Sarnatherm® Polyiso Insulation provides superior thermal performance. Unlike other insulating solutions, Polyiso is compatible with a wide variety of roofing systems including both single-ply PVC and liquid-applied membranes (LAM). The result is a versatile thermal roofing system that provides an enhanced building envelope, leading to a comfortable indoor environment with reduced heating and cooling loads. |
| T02 Verified Thermal Comfort | Enhance thermal comfort and promote human productivity by ensuring that a substantial majority of building users (above 80%) perceive their environment as thermally acceptable. | Sarnatherm® Polyiso Insulation provides superior thermal performance. Unlike other insulating solutions, Polyiso is compatible with a wide variety of roofing systems including both single-ply PVC and liquid-applied membranes (LAM). The result is a versatile thermal roofing system that provides an enhanced building envelope, leading to a comfortable indoor environment with reduced heating and cooling loads. This solution contributes towards a maximum of three points. |

| X01 Material Restrictions | Reduce or eliminate human exposure to building materials known to be hazardous. | Several Sika® Roofing products do not contain any intentionally added asbestos, mercury, or lead in concentrations greater than 0.1% (1000 ppm) by weight. Please contact us for more information on this credit. |
| X05 Enhanced Material Restrictions | Minimize the exposure to certain chemicals by limiting their presence in products. | Several Sika® Roofing products do not contain halogenated flame retardants (HFR), Per- and polyfluoroalkyl substances (PFAS), and Orthophthalates. This solution can contribute towards one point. |
| X06 VOC Restrictions | Minimize the impact of volatile organic compounds (VOCs) emitted by products on indoor air quality. | Several Sika® Roofing products have undergone volatile organic compound (VOC) emissions testing. This testing is done in accordance with the California Department of Public Health (CPHD) Method v1.2-2017. These solutions contribute towards two points. |
| X07 Materials Transparency | Promote material transparency across building material and product supply chain. | Sarnafil® G 410 and Sarnafil® S 327 have third party verified Material Ingredient Reports (MIR). Monolithic Membrane 6125®, MM6125® Surface Conditioner, Flex Flash-F, and Hydroflex 30 have a Health Product Declaration (HPD) which is compliant with the Health Product Declaration Open Standard. |
