Too Tight! Edge of the Cliff Ventilation

Thursday, April 26

Location: Salon A (5th Floor)
CEUs: BPI, InterNachi, NATE, NARI, ASHI

“Can a house be too tight?” Yes is the answer to two parts of this question. There is a long term and a short term consideration regarding the tightness of the house. The long term issues are the health of the occupants and the durability of the structure. The parameters of the long term issues are guided by ASHRAE 62.2. The short term consideration is the operation of atmospherically vented appliances which is guided by the BPI 1100 and 1200 Standards. These two issues are interwoven and if performed incorrectly can result in dramatically negative outcomes.
This 90 minute session relates these issues to forensic analysis of a home where a death from CO occurred. The home was weatherized. Did they make it too tight? Could this result have been avoided? This analysis clearly points to the critical nature of careful execution of following the prescribed protocols.
