Municipal lives for HVAC (D30)

43 municipalities in Ontario, British Columbia and Alberta state a life for HVAC as a whole, in 35 distinct tables: 10–50 years, median 20. These come from capital asset policies: accounting lives, used for amortization. They describe the system rather than this component, and none is a measured life.
