Mike Butler: ‘Damp rental’ beliefs rubbished

Fewer than 3 percent of tenants find their homes cold and damp, the World Health Organisation did not recommend a healthy temperature, and client-friendly research helped understate the costs of heating and insulation proposals for rental property, according to a discussion document released today.

Iconoclastic economist Ian Harrison of Tailrisk Economics has taken aim at the cherished beliefs of Housing Minister Phil Twyford in a discussion document titled The proposed Healthy Homes Regulations: An Assessment.

Twyford is finalising a series of standards for New Zealand’s 588,700 rental properties on heating, insulation, ventilation, moisture and draught-proofing under the so-called Healthy Homes Guarantee Act that was passed last December.
