Achieving sustainability and wellbeing goals can deliver wide-ranging benefits, for example:
  • Improved productivity (eg 15% reduction in non-value-added time)
  • Reduced sickness and absenteeism (eg 28% reduction in sick days)
  • Increased sustainability (eg 20% energy cost saving in HVAC)

Whether you are seeking to improve sustainability or meet goals relating to the wellbeing of your employees, we provide support to realise your ambitions. A range of certifications enable you to measure and validate your sustainability performance and your activities to promote employee wellbeing. We offer assistance in achieving sustainability certificates like BREEAM and LEED and wellbeing certificates like WELL and Fitwel.

Wellbeing certificates WELL and Fitwel

The built environment contributes greatly to wellbeing, job satisfaction and productivity. In recent years, more attention has been paid to making health and wellbeing in buildings tangible and measurable. The effects of a healthy building are considerable.

Bespoke health & sustainability solutions

Our services do not stop at the above named certification guidance. There is an alternative solution for clients who wish to perform according to best practices, but do not have ambition to certify. We can set up a bespoke set of guidelines for health and sustainability, based on our comprehensive knowledge of certification schemes. Bespoke guidelines can draw together strategies and evidence-based performance criteria from a number of certifications including LEED, BREEAM, WELL and Fitwel.

Wellbeing certificates WELL Building Standard and Fitwel

Studies have shown that a healthier and pleasant working environment contributes to the performance of employees. A great workplace adds value for your people and your business across many dimensions. The effects of healthy buildings & work environments are scientifically proven, backed up with comprehensive data. Companies are pioneering with certified healthy buildings.

The WELL Building Standard and Fitwel are certification methods that focus on health and wellbeing of building users, guests and employees. We provide support and guidance in the process of creating healthier work environments, using healthy building standards for certification, and also as a reference for bespoke guidelines.

WELL Building Standard

The WELL Building Standard focuses on the health of occupants and is based on years of scientific research. It is an integrated approach to health and wellbeing, created around 10 WELL concepts: Air, Water, Nourishment, Light, Movement, Thermal Comfort, Sound, Materials, Mind and Community. Within these 10 concepts are more than 100 features – pre-conditions or optimisations - which are further divided into specific requirements. Our WELL APs (Accredited Professionals) can assist you in all phases, from quick scan or gap analysis to certification guidance.


Fitwel Certification is also based on scientific research but is less rigorous than WELL and focuses more on the less technical aspects of healthy buildings. In addition, it has fewer features relating to policy and human resources than WELL. This makes it a very suitable certification for existing buildings.  Fitwel is not based on prerequisites, but only has optional credits. Fitwel has 12 sections: Location, Building Access, Outdoor Spaces, Entrances and Ground Floor, Stairs, Indoor Environment, Workspaces, Shared Spaces, Water Supply, Prepared Food Areas, Vending Machines and Snack Bars, and Emergency Preparedness. Our Fitwel Ambassadors are available to assist with your Fitwel certification process.

New modules introduced by WELL and Fitwel respond to the COVID-19 pandemic, addressing safety aspects of health and wellbeing. They include mitigating the risk of transmission of contagious disease, air quality, cleaning and emergency plans. The strategies for certification are relevant for buildings during the pandemic and will continue to have value in the post COVID-19 environment, building occupant trust in office safety.
