A guide to workplace wellness design for a green healthy office


In this mini guide to designing healthy offices as part of a workplace wellness strategy, we cover what we consider to be the key fundamentals to get right: Indoor Air Quality (IAQ); Acoustic Comfort; Biophilic design; Thermal Comfort and Physical wellbeing.

We divide our content up into the distinct themes of a workplace wellness and wellbeing consultancy project, from construction, to interiors design and building operations as each phase offers distinct opportunities.


Indoor Air Quality (IAQ)

Indoor Air Quality (IAQ)plays a vital role in shaping a healthy office, optimizing productivity and cognitive function, while indirectly reducing absenteeism.

It refers to the cleanliness and safety of the air within a building, encompassing a variety of potentially harmful pollutants, VOCs, dust particles and so on. 

By reducing the risk of allergies and respiratory problems, workers are assured of a healthier office environment to work in each day.

Investing in IAQ not only creates an appealing, healthy workspace but also cultivates employee well-being and boosts productivity.

But don't take our word for it, before we get into the 'how' let's review some of the more prominent research studies into this topic.

IAQ Design Concepts: Construction Phase

  1. Natural Ventilation

    1. Operable Windows: Ensuring windows can be opened to allow fresh air circulation. Windows should be able to partially or fully open, allowing occupants to control airflow.

    2. Cross Ventilation: Position windows or vents across each other to create a natural cross-ventilation effect.

      1. Skylights can offer an extra bit of ventilation.

    3. Ventilation Design: Design HVAC systems that naturally optimize airflow. This may involve placing vents of openings in areas where prevailing winds can be harnessed.

    4. Atriums and Courtyards: These open spaces draw air into the building, improving air quality by acting as natural ventilation channels.

    5. Pathways: Design open floor plans to minimize obstructions to airflow.

  2. Chemical Storage Ventilation

    1. Ensure proper ventilation in janitor closets, copy/print rooms, storage rooms, and other places that include the use of chemicals.


IAQ Design Concepts: Refurbishment

  1. Air Filters

    1. High-Efficiency Particulate Air (HEPA) Filters: HEPA filters capture tiny particulates like dust, pollen, and airborne viruses and contaminants. 

      1. If HEPA is not possible, make sure your filter is MERV 13 or higher

    2. Activated Carbon Filters: These filters remove VOC’s, odors and gases, which is essential to keeping a clean workspace.

  2. Non-Toxic Healthy Materials

    1. Green Purchasing Policy: Look out for these chemicals that are linked to harming your health and ensure a plan for the selection of product.

      1. PFAS: coined as ‘forever chemicals’, these chemicals stay in the environment and in the body indefinitely and disrupt hormonal functions.

      2. Antimicrobials: these are associated with reproductive problems.

      3. Flame retardants: Though added to products to meet flammability standards, they are known to harm human health, even without improving fire safety.

      4. Bisphenols + Phthalates: Another hormone-disrupting chemical found in food containers and flooring.

      5. Some Solvents: Products like oil-based paints and sealants contain solvents that are linked to neurological problems.

      6. Certain Metals: Some metals found in paint and fluorescent lights can be a risk to pregnant women and children.

      7. ​​Fact Sheet: The Living Building Challenge (LBC) Red List 2023 Update: A Guide for Project Teams. (a guide on what specific chemicals to avoid)

    2. Check for specific eco-friendly and sustainable, non-toxic certifications for paint, finishes, and furniture such as:

      1. Greenguard: Evaluates products for their low emotions of volatile organic compounds and other harmful pollutants. 

      2. Green Seal: Sets environmental standards for cleaning supplies, paints, building materials, etc. It ensures that certified products meet specific criteria for sustainability, performance, and health.

Acoustic Comfort

Acoustic comfort refers to the quality of the acoustics within an indoor environment and its impact on the people working there.

When designing a workspace for wellness, ensuring a high degree of perceived and real acoustic comfort is crucial for mental health in particular. 

Proper sound management can significantly enhance workplace wellness by reducing noise-related stress in office environments. 

Surveys show that mismanaged noise within offices impacts concentration, leading to headaches, distractions and low level stress that impede rather than enhance productivity. 

By creating a quiet workspace with just the right amount of ambient background sound (note: not noise!), employers can feel confident that they promote health amongst employees in their regular work environment.

Promoting physical wellbeing in a healthy office

Creating a wellness-focused office environment for physical well-being is critical, with ergonomics and active design two essential elements to achieve this goal. 

By implementing ergonomic designs that fit the needs and capabilities of employees, you can promote comfort, reduce strain, and prevent injuries. 

Ergonomic design involves a focus on creating products and environments that are comfortable and safe for people to use.

It aims to answer the question, "How do we design a workspace that fits the employee's needs rather than having employees mold into their space?" 

Incorporatingactive design into the workday encourages movement and physical activity, leading to healthier behaviors and a more engaged workforce.

With reduced physical discomfort and improved posture, absenteeism can decrease, and employers can take less time off work due to back pains and discomfort, leading to a reduction in healthcare costs. 

Giving workers options on how they want to work leads to higher productivity and a positive corporate image as a wellness-focused employer.

By implementing both ergonomic design and active design, you can create a company culture and an environment where employees can thrive and be more productive.
