$1 on insulation brings $6 health benefits
Non-profit research institute Motu Economics looked at the first 45,000 homes retrofitted with insulation under the Warm Up NZ Programme, and found the scheme had a 6:1 benefit-to-cost ratio.
That meant that every dollar spent on insulation brought $6 of benefits.
Motu Economics senior fellow Arthur Grimes said the research showed retrofitting insulation prevented one death for every 1000 homes insulated.
The study used the same methodology for valuing life as researchers did when assessing the benefits of roading improvements.
