Know your building's clean air rate, measure against ASHRAE Standard 241. 

BreatheScore Certify's air tracer technology is the industry’s most innovative and advanced ventilation monitoring and air health certification system, and the only method with fully digital testing for ASHRAE Standard 241 providing fast, precise, zone-by-zone ventilation performance assessment and optimization.


Having worked with hundreds of commercial real estate buildings and their owners, we have learned that inefficient, costly testing leads to tenant and occupant concerns, directly impacting KPIs, sustainability, and revenue.

Poppy provides easy, one day testing and instant results to demonstrate what’s working and what’s not while uncovering ways to save without increasing risk.

Better results. Less cost.  More profit.

BreatheScore gives you instant results, in the palm of your hand, as well as comparison data in our dashboard, allowing you to optimize, retest, run scenarios, validate assumptions, identify challenges and opportunities, as well as quantify the impact of air purifiers, UVC, open windows, and HVAC seasonal settings.


BreatheScore quantifies the effects of all products that impact air health to gauge the ongoing health of your spaces. 

Why does building air safety matter?

Picture this:



In just 20 minutes, our cutting-edge technology not only provides you with equivalent clean air (ECA) and effective air changes per hour (eACH), but we're taking it a step further.


We're thrilled to introduce a groundbreaking addition inspired by ASHRAE Standard 241 – the ability to measure and determine the precise number of occupants a space is safely suited for. This is a game-changer that sets a new standard for safety and compliance.

If that is not enough, how about saving 15% on your energy bill? For a typical 200,000 sqft Class A building, that is 52,000 savings, annually.

A modern approach
to ventilation testing.


Measuring ventilation performance is due for a massive upgrade. For decades, most buildings are only tested when needing to meet occupancy building codes. The process has been manual, costly, and time-consuming, often resulting in incomplete evaluations.

Icon balanced indoor air flow digital 241
Test, measure, and optimize more often.


Tenants and occupants are more concerned about indoor air health than ever. Additionally, changing standards requires organizations to test more frequently. With a quick and accurate way to measure ventilation performance, businesses can take advantage of opportunities to reduce costs and increase building health.

BreatheScore provides accurate, fast, actionable data for continuous validation and insights. It considers your HVAC system, air purifiers, and other disinfection methods to provide a comprehensive look into your healthy building strategy by collecting data across all these systems anytime performance adjustments are made.

Our comprehensive, proactive testing approach allows you to access and quantify your air health strategies to determine which work and which aren’t worth the energy or effort.

We're ready when you are. Get started today.


BreathScore Professional Scan:

the industry's most advanced infectious aerosol pathway technology — in 3D.



With unmatched spatial intelligence, BreatheScore Professional Scan uses a high-density sensor network to provide 3D tracking of how infectious particles build up, travel, and clear over time.

BreatheScore Professional Scan can be added to a certification test and combines Matterport scans and sensor data to capture unprecedented airflow and aerosol dynamics data at the room, between-room, and floor-to-floor level. Each scan renders a 3D digital twin which can be explored intuitively using Poppy’s BreatheScore Professional Scan browser based web application.
