The Senate Standing Committee on Housing, Construction and Community Development voted to report S8078 — legislation to amend multiple dwelling law related to standards for openable windows in residential units — to the floor after a policy discussion about ventilation standards.
Sponsors and some committee members said the bill is intended to facilitate conversion of commercial buildings with central HVAC systems into residential units by allowing applicable commercial air‑handling or ASHRAE standards to satisfy existing requirements that windows be openable in some cases. Supporters argued many commercial buildings are designed for central HVAC and retrofitting windows to be openable can be costly or infeasible.
Other members objected that applying commercial ventilation standards would “ignore the whole‑house and local exhaust principles” embedded in the ASHRAE 62.2 residential standard and said indoor‑air quality and shared‑air concerns remain important, especially following COVID‑era experience. Those members said they intended to register “no” votes and asked sponsors to continue discussions about whether and how commercial standards could safely be substituted.
On the floor of the committee, senators moved and seconded to report the bill to the full Senate. Named negative votes and a member recorded as voting “without recommendation” were noted in the transcript; the bill was reported. The committee said it will continue conversations with sponsors and interested stakeholders as the bill advances.
