Design founded on empathy and safety can help inform a healthier working environment for building occupants  

 

When the COVID-19 pandemic winds down and communities emerge from quarantine and work-from-home, it’s very likely that residual fear about workplace health and safety will linger. We’ll all be more acutely aware of the hazards associated with surfaces we touch and the people we interact with after this prolonged period of social distancing. This awareness will take a toll on our physical and, most notably, mental health.

In the wake of the COVID-19 pandemic, the connection between the physical environment and wellness will be clearer than ever before. We’ll view the spaces and places in which we live, work, and play through a different lens. Is the air in this building filtered? Are there proper hand-washing facilities? How many surfaces do I need to touch and how clean are they? Where can I go for a quiet break if the office crowd is too much after being away?

People are fundamental to design, construction, operations, and development decisions. When we focus on the human experience of the buildings and spaces we design, we have the ability to add meaningful value to real estate assets, generate savings in personnel costs, enhance human health and well-being, and enrich the overall experience of spaces and places.

 

Employers, property owners, and facility managers must prepare for the new mindset

Our wealth of experience in the healthcare sector, combined with our deep understanding of wellness certifications like WELL and Fitwel, have taught us how to leverage design, operations, and policies to proactively address risks of pathogen transmission and create restorative environments where building occupants feel safe, comfortable, and supported. We know what it means to design for a strong and resilient workforce.

These are unprecedented times, calling for creative and innovative responses founded in human empathy and safety. Our goal is to help communities foster human resilience as we navigate a rapidly changing world.

Immediate action

How do we help our clients realize measurable value on investment into the health, well-being, and happiness of building occupants?

It’s clear we are racing against time and extremely bad odds. This is a global issue like one the world hasn’t faced in generations, with over 200 countries now reporting cases of COVID-19. Based on what is known about the disease, the U.S. Centers for Disease Control and Prevention projected that the virus could infect 160 million to 214 million people across the country, requiring more than 20 million hospitalizations in a system that has less than a million beds. In Canada, the federal government has predicted that anywhere from 11 million to 27 million people, up to 70% of the population, could be infected. 

Globally, the numbers are concerning, notably in areas of the world that do not have the healthcare infrastructure to address the burden that has already been seen in countries like Italy and that is being experienced around the world. As global data emerges about the resilience of existing healthcare infrastructure, a study by the Harvard Global Health Institute projected that even in a moderate infection scenario, 40% of US markets would not have enough hospital beds. In the event of a more extreme infection rate, many parts of the US would need to add or empty up to 800% more beds, which seems impossible in a system already pushed to its limits.

The WELL Building Standard™ is a comprehensive framework for the design strategies, operations protocols, and organizational policies that aims to measurably improve the safety and health of people in indoor spaces. From our architects and interior designers, to our mechanical engineers and sustainability consultants, our WELL Building experience enables us to provide a facility assessment with respect to human health and well-being. In the context of the most pressing issues arising from COVID-19, we encourage all employers and property managers to prioritize consideration of the following five strategies and measures: 

  1. Building condition assessments
  2. Indoor air quality
  3. Hand-washing infrastructure
  4. Industrial hygiene
  5. Mental health design support

 

1. Building condition assessments and retro-commissioning

Retro-commissioning is a systematic process developed to improve an existing building’s performance. When applied to existing “older” buildings, commissioning identifies deficiencies, uncovers problems, and offers recommendations for sound, cost-effective solutions for correction.

During this COVID-19 pandemic, retro-commissioning has never been more important. Buildings are sitting vacant and being shut down, HVAC problems are not being addressed, and systems are potentially becoming uncalibrated. More critically, there is an urgent need for space and specialized equipment to care for COVID-19 patients. Healthcare administrators need accurate _q_tweetable:Our goal is to help people feel supported, protected, and more resilient as we all navigate a rapidly changing world._q_data and sound guidance to make immediate prudent decisions that will save lives. This is not a one-size-fits-all approach. We need a range of solutions for different members of our community and their respective roles in the response to this pandemic. Examples include converting convention centers into acute- and critical-care centers; creating dedicated, clearly marked, testing spaces in hospital lobbies; and dedicating hotels to providing a safe place for essential workers to sleep if isolation from family members is necessary.

States like California and Washington have responded by adapting existing buildings like hotels, including converting an EconoLodge near Seattle, into a coronavirus quarantine facility. In Chicago, our team is working with the USACE to build out 3,000 beds in the local convention center to care for those inflicted with the virus. But there are limits to this approach.

According to Sara Bayramzadeh, a professor and coordinator of the healthcare design program at Kent State University, retrofitting buildings for healthcare needs, especially during an infectious disease outbreak, requires fulfilling stringent requirements. These include the use of materials that are durable and can be easily cleaned, being able to install negative air-pressure systems to prevent the spread of infection, and laying in critical infrastructure like medical gas-supply systems. Additionally, once the pandemic response has abated there will be a significant need for decommissioning in order to return the facilities to their original function.

Having a clear retro-commissioning or repurposing strategy to hit the ground running and turn an unused building into a clean, functioning care facility takes the right team of people and the right tools.

Pandemic-related priorities:

  • Assess building systems and controls functionality, including air and water quality issues, in buildings that have been vacant

Immediate interventions:

  • Building assessment, audits, and retro-commissioning of HVAC, plumbing, lighting, IT, and fire protection systems to verify operational ability after a prolonged shutdown or reduction in occupancy-related loads
  • Controls testing
  • Building flush-out, if necessary (e.g., in event of damage or contamination)
  • Full electrical system inspection—from outside transformers to each panel, breaker, circuit, switch, receptacle, low voltage, etc.
  • Quality assurance procedures that focus on building enclosure components, including:
    • Implementation of materials that are durable and can easily be cleaned
    • Installation of negative air-pressure systems to prevent the spread of infection
    • Inspection and removal of mold, asbestos, and lead

 

2. Indoor air quality

Well-designed, installed, and monitored mechanical and plumbing systems produce healthy indoor environments where pathogens are filtered, diluted, and removed from the occupant breathing zone. Our mechanical engineers apply fundamental principles of thermodynamics and building physics (humidity, air flow, differential pressurization), smart controls and sequencing of operations, and innovative ventilation and filtration technologies to mitigate the presence and spread of potential pathogens and allergens.

As the infection pathways of COVID-19 continue to be discovered and better understood, guidance is shifting regarding criteria such as the optimal relative humidity levels to maintain in building and criteria around air filtration. Our team is at the forefront of industry guidelines and will adapt to the best evidence available for appropriate testing procedures and mechanical design.

Pandemic-related priorities:

  • Rapidly address indoor air quality issues—perceived and actual—in existing buildings

Immediate interventions:

  • Conduct air quality assessments, testing, design and provide engineering guidance to improve ventilation effectiveness of existing HVAC systems, support long-term air-quality monitoring, and create air-quality awareness
  • Adapt controls and sequencing to accommodate and monitor additional filtration needs, and additional criteria concerning recirculated air systems
  • Develop messaging and education for building occupants—dashboards, apps, situational cues—to reduce concerns regarding potential pathogen transmission

 

3. Hand-washing infrastructure

Hand washing must be approached as both an infrastructure issue as well as behavioral one. Strategically positioned hand-washing infrastructure, including space clearance in sinks, can limit touch points and reduce opportunities for pathogen transmission. Ensuring that water temperature and pressure is high enough to support hand washing, is crucial. Behavioral strategies can be addressed by ensuring automatically controlled/sensor-based faucets run for the recommended 20 seconds of hand-washing time. Lights can be placed over sinks to provide a visual cue on timing. Dynamic signage can act as a visual reminder—for situational cues to be effective they should change frequently to avoid blending into the background noise of restrooms.

Paper towels also provide an additional level of cleaning and reduce the spread of contamination that can be found with using hand dryers—an example of potential conflicts between pathogen control and sustainability that we may see in the future. One solution: Use paper towels made from recycled paper and investigate opportunities for waste management to collect them for compost!

Pandemic-related priorities:

  • Increase adoption of and cultural engagement in proper hand-washing practices to mitigate concerns in shared work spaces and reduce the risk of pathogen transmission among occupants

Immediate interventions:

  • Carry out water quality and hand-washing infrastructure assessment, testing, and building audits
  • Develop and/or review operational policies for access, custodial services, and maintenance of hand-washing facilities
  • Provide situational cues, messaging, and branding to engage and educate all occupants in proper hand-washing practices

 

4. Industrial hygiene

Understanding the risk and safety associated with indoor environments will be key for owners and facility managers as building occupants return to work. Early identification of worksite hazards and evaluation of the related risk will support the implementation of appropriate precautions and controls. Especially in our current and post COVID-19 reality, mitigating harm to workers is key to bolstering human resilience in the face of disaster.

Pandemic priorities:

  • Identification of indoor air quality risks and issues
  • Manage remediation and cleaning of contaminated workplaces and sites

Immediate interventions:

  • Indoor air quality assessments
  • Site risk assessments
  • Support during remediation and cleaning activities of contaminated sites, including training, emergency response planning, occupational exposure assessments
  • Develop strategies for communicating complex and rapidly changing information on infection control to employees in a way that addresses their concerns

 

5. Mental health design support

The fear and stress associated with the COVID-19 pandemic is unprecedented for most of the world and will have both short- and long-term mental and physical health impacts.

Fear about leaving home—which is being promoted as the safest space—along with the strain of changing work-life balance and increased isolation in an already lonely society creates an opportunity for long-lasting trauma. Already people are developing agoraphobic tendencies, where they are scared to leave their home, and children are likely picking up on the stress felt by their families. Perceived and actual safety and comfort is paramount during this time and for the years to come.

As we come out of our work-from-home situations and physical distancing, harnessing the power of design to heal gives us an incredible opportunity to aid in psychological recovery.

Pandemic-related priorities:

  • Mental health concerns arising from prolonged periods of physical and social distancing, fear of leaving the home, fear of repeat infection, and exposure to pathogens in public spaces and workplaces

Immediate interventions:

  • Building assessment to identify opportunities to enhance or implement evidence-based restorative design strategies and building features in existing buildings
  • Development and implementation of biophilic design principles proven to have an immediate, positive impact on mental health. Through a funding stream dedicated to encouraging creativity and innovation in design, Stantec recently sponsored biophilic design research through the Healthy Building Program at Harvard T.H. Chan School of Public Health. The results showed that biophilic interventions had consistent positive impacts on blood pressure, heart rate, heart rate variability, and skin conductance levels across all biophilic interventions and all spaces. 
  • Operational protocols and organizational policies that impact the mental health and well-being, safety and security of occupants. Strategies are grounded in the principles of biophilic design principles.
  • Consulting and facilitation of WELL Building Standard certification. WELL is the industry leading framework for addressing indoor environmental quality related to the prevention of contaminant sources and distribution, and mental health and organizational resiliency via design, operational preparedness, and policies.
