Municipal lives for HVAC (D30)
48 municipalities in Ontario, British Columbia and Alberta state a life for HVAC as a whole, in 39 distinct tables: 10–50 years, median 20. 65 rows come from capital asset policies (accounting lives, used for amortization) and 6 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.
