Our mission is to

organize the world’s facility ventilation information and make it universally accessible and useful,

and offer in Room Ventilation Alarm products.

We gather

user observations when they visit facilities,

import site survey data from facility managers,

import Government certified data from sources like schools and test labs,

we do our own research to find facility ventilation data already on the web,

and we connect our ventilation alarm products to F V S E.

We present data in a variety of ways

building summaries, room details, groups of buildings statistics, reports, certificates, etc

using various views meant to convey the most essential information as quickly as possible.

Our in room ventilation alarm products

alert occupants when there are problems

and they continuously send data to F V S E.

It all starts with a F V S E query.


Our Vision

  1. Make everyone aware of ventilation performance levels using official industry terms - Air Changes Per Hour or ACH or eACH.
  2. Disclose the ventilation performance levels in terms of ACH or eACH levels, everywhere.
  3. If the ventilation level drops below a certain ACH or eACH level, generate alarms in affected rooms, in the same way that smoke detectors generate alarms to alert occupants to fire hazards.

Our facility ventilation systems started to fail us slowly with the start of the energy crisis in the 1970's. As time moved on it just became worse and it is not getting better. This is a  long term problem. It is not going away. We have the technologies, we know what to do, this is a social problem. Only you can make this final vision of safe ventilation levels in our buildings, planes, trains, busses, and other spaces.

Start using F V S E today.

Add your observations.

Reach out to your schools and places of work and ask them to provide data for F V S E.

Contact us about our Ventilation Alarm products that alert occupants to ventilation problems.

It all has to start somewhere and this is the place and the time.


Ventilation Basics

A building ventilation system is a life support system.

If the ventilation is not working properly people will be infected by airborne contagions.

Ventilation performance is key to ensure that the risk of infection is minimized or eliminated in a room.

Ventilation is measured in terms of Air Changes per Hour (ACH) or Equivalent (eACH) for UV based systems.

If the ACH is zero people will be infected by an airborne contagion.

As the ACH level increases the risk of infection drops.

For hospital rooms with airborne contagions the CDC recommends a minimum of 12 ACH.

The Heating Ventilation and Cooling (HVAC) systems and UV systems are the primary approaches used to ventilate buildings.

Many  buildings have poor maintenance with closed off vents, failed fans, or poor operations where the system is turned off when people are present.

Many  buildings have systems that are too small.

The Facility Ventilation Reporting service allows people to take control of their environments and examine the ventilation rates of the buildings that they visit.

Anyone can add buildings to the database if there is no data.

The CAB data is a summary of a facility.

The ACH data (including eACH) has multiple rooms found in a facility.

The data currently is based on visitor observations and site surveys some of which is Certified by Government authorities.

In the future, there will be real time data providing the latest ventilation status.

Why should facility occupants participate

  1. Occupants are alerted to ventilation problems just like smoke detectors alert occupants to fire hazards.
  2. Social media and crowdsourcing ventilation data will significantly help to deal with airborne contagion risk.

Why should facilities disclose their ventilation data in the public database

  1. All things being equal, people and companies will avoid facilities that will not disclose their ventilation data.
  2. Occupants want to know and they have a right to know the ventilation levels in the facilities they visit.

Why should facilities install the new Ventilation Alarms System

  1. Sensors are right at the interface vent rather than down stream giving accurate real time ventilation data for each room to ensure the building is properly balanced and not wasting energy.
  2. Sensors today are for a zone and a zone typically serves multiple rooms, someone may have closed the vents in a room, with no indication of the serious problem.
  3. Sensors today do not alert occupants to ventilation problems, they only alert maintenance staff.
  4. Accurate data is available for labs that must prove via documented evidence the ventilation levels needed for certification in a room.
  5. Costly site surveys with poor and old data results are no longer needed.
  6. Employers have real data that they properly responded to the ventilation problems that the COVID-19 disaster surfaced.
  7. Building owners can use this as a fact based value discriminator to increase occupancy rates and bring people back into empty offices.
  8. All things being equal, early adopters will attract greater revenues when companies and people decide which facilities they will pick.
  9. Self insured employers will have reduced health care costs.
  10. Over 1 million people died and the country was shut down for almost 2 years. It is clear that we must not allow our facilities to cause another airborne infection disaster ever again.
  11. There is much more that we uncovered to justify investment in this system.
