People spend 90% of their time indoors.

Does your building support occupant health?

Learn about the B4H Platform

How do you evaluate a building’s influence on human health?

Current building standards focus on aesthetics, energy and dramatic failures like fire and earthquakes … not on occupant health.

Who decides?

  • Architects
  • Designers
  • Business Executives
  • Engineers

With no official health standard for buildings … how do you really know if your building supports human health?

Where are the medical professionals?

Learn About Our Medical Approach

Our medical expertise brings occupant health into focus

Dr. Taylor is a Physician from Harvard Medical School with a Masters in Architecture.

She discovered the importance of relative humidity in reducing hospital infections and improving patient outcomes.

Her current research focuses on: 

  • the interaction of indoor air and surfaces
  • the microbiome of the built environment 
  • the influence of the indoor environment on acute and chronic illnesses

Look through the lens of human health to see what others do not

B4H sees …

A building’s living ecosystem.

  • Filled with gases and particles that enter from the outdoor environment and are emitted by the people inside

Complex interactions of indoor factors with microbial communities and human physiology.    

For example:

  • 80% of influenza viruses can be inactivated in 15 minutes when relative humidity is 40–60%
  • There is a 9% decrease in productivity with poor air quality

Whether the building ecosystem promotes health or disease.

By measuring your building’s real-time impact on human health … you can see it and you can improve it.

The B4H Platform

Three steps to see and optimize the
influence of buildings on human health


Continuously monitor and measure

our Sensors

Evaluate influence on occupant health through a medical lens

our Algorithm

Report real-time conditions, recommend actions and measure response to remediation

Our Dashboard

Continuously monitor and measure

Our sensors detect and measure ALL indoor air quality components necessary to understand the influence on human health.

We continuously monitor 11 medically-verified variables:

  • Indoor thermal metrics (temperature, relative humidity)
  • Particle counts and sizes
  • Total volatile organic compounds (TVOCs)
  • Other relevant gases (carbon dioxide, carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide)

These constituents and their interactions have a quantifiable influence on the human body.

The sensors wirelessly transmit data to the B4H cloud for analysis and safe storage.


Evaluate influence on occupant health through a medical lens 

The Human Health Lens

We are guided by data from:

  • indoor air quality research
  • building sciences
  • medicine and microbiology

B4H distills knowledge from these areas of research into an advanced proprietary algorithm which evaluates the real-time influence of indoor air on occupant health.

The B4H.Dx Score


The resulting B4H.Dx score is a single number from 0 to 100.

A score of 50 and above indicates an environment that supports human health. Components of the score have been correlated with reduced risks of viral infection, respiratory and other diseases, and impaired cognition. Consequently, a high score reflects short and long-term health benefits.

A low B4H.Dx score will improve when suggested remediation actions are taken.

Learn about our dashboard

Report real-time conditions, recommend actions and measure response to remediation

The B4H Dashboard lets you see your B4H.Dx score and its component parts in real-time, in the building overall and in its individual zones.


  • In the event of a low score, you receive timely alerts


  • Based upon our algorithm and analysis, we make recommendations for remediation if necessary

Remediation Check

  • The B4H.Dx score can measure an determine whether interventions are effective (e.g., filtration, humidification and other remediation)

The B4H.Dx score and Dashboard offer tangible proof of your commitment to occupant well-being.

Why this matters:
 Better occupant health ...
‍Covid-19 and beyond

Occupants will feel a sense of confidence knowing that their health is being protected and nurtured every day.


The B4H.Dx score drives occupant confidence, knowing that their health is constantly considered in building decisions and actions.


Maintaining a good B4H.Dx score creates environments that protect occupants from conditions that are harmful to human health and productivity.


Actions that optimize the B4H.Dx score create indoor conditions that reduce fatigue, stress, allergies and other health problems, and enhance productivity.

Why this matters:
ROI and the bottom line

The B4H platform supports quantifiable economic returns in every type of building.

Commercial Businesses

Communicable respiratory illnesses cost business owners over $225 billion per year due to absenteeism, decreased worker satisfaction and diminished productivity.

Increase occupant function and productivity

Attract and retain tenant talent

Differentiate buildings in low occupancy, competitive markets


Poor indoor air quality reduces student grades by 3-7% and lowers the number of students performing in the highest categories of standardized testing in math and reading by 3-4%.

Enhance learning through improved concentration, memory, energy levels and motor skills

Decrease absenteeism

Improve test scores

Senior Care

Optimized indoor environments improve resident health, decreasing acute illnesses that require transfers to hospitals, supporting patient memory and balance, and decreasing mortality rates.

Improve resident health and function

Build brand equity via health content and education

Differentiate your brand with our proactive monitoring for health

B4H: Setting a human health standard for buildings

Historically buildings have focused on shelter and comfort, then sustainability and energy efficiency.


B4H has created a new standard within the broader “healthy building” and “indoor air quality” space … based on human health.

B4H believes that occupant health should be the epicenter of all building decisions.

Building4Health is the authoritative lens on the influence of the indoor environment on human health.
