Catch our IEQ discussion with Sam and Cheryll & the Rock House team - the ‹beresses of  design on their nationally broadcasted “At Home” radio program. is on-line educational resource for those who want to self-study indoor climates, building and health sciences related to buildings, radiant based HVAC systems and dedicated outdoor air systems. Since 2004 we have developed over 1.6 GB of information for you to access for free. This complimentary service is operated as not for profit and funded by donations and contributions from volunteers and other organizations and educational institutes.

If you want to participate in pro bono discussions with questions regarding indoor air quality, indoor comfort quality, radiant based HVAC systems, equipment, applications, projects etc., heat recovery, humidification etc..., or want to participate in general discussions on the business of buildings, product ergonomics, marketing, public relations, research in the building and health sciences etc...then,

post your question and comments here

For those who want or need to go the next step for personal contact we do offer private visitor servicess. These are individual services catered to your project
