Sustainable and Healthy Facility Ventilation in the 21st Century

We know we need to reduce facility ventilation carbon footprints but not at the cost of lost health or epidemics.

Welcome to CassBeth. Our current focus is Ventilation Research, Education, Quality Improvement Indicators (QII), Ventilation Measurement Assessment Protocols, and a Ventilation Standard to address airborne contagions in all public and private facilities. We offer a Facility Ventilation Search Engine (FVSE) of thousands of buildings showing their ventilation performance levels. Once our indicators and or protocols are executed the same level of information will be available to an organization that is shown in the various reports provided with FVSE search results. Our Cassbeth Ventilation Standard when used as a supplement closes all gaps in other standards and allows organizations to effectively perform maintenance and plan for upgrades, retrofits, and new construction in this new age of harmful airborne contagions.

Our Vision

  1. Make everyone aware of ventilation performance levels using official industry terms - Air Changes Per Hour or ACH or eACH.
  2. Help everyone understand their facilities ventilation performance levels using our QIIs that cover all issues and yet can be executed by anyone.
  3. Help everyone plan for effective ventilation systems using our Ventilation Standard that closes all gaps in all other standards.
  4. Disclose the ventilation performance levels in terms of ACH or eACH levels, everywhere using FVSE.
  5. Identify when ventilation levels drop to alert occupants of poor ventilation hazards.

Most facilities are in the Low End categories. Our facility ventilation systems started to fail us slowly with the start of the energy crisis in the 1970's. It became worse in the 1980s when cigarette smoking was banned in buildings. 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. Today the goal is to reduce carbon footprint but not at the cost of lost health or epidemics. Because of this relationship we continue our work started in 2006 on climate change and sustainability.

There are effective system choices to achieve both health and reduced carbon footprint. 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. It all has to start somewhere and this is the place and the time.
