Buildings are overheating at the Tauriko Business Estate because anti-glare factory roofs are absorbing too much heat.
The problem, created by Tauranga City Council planning rules to avoid glare impacting on householders living at The Lakes, surfaced at a meeting of the council today.
The current rule required roofs to be painted in darker colours so that their "reflectance value" was no more than minor and did not exceed 35 per cent.
Feedback from developers was that complying with the rule had resulted in a roof colour that held excessive heat and caused buildings to overheat.
Councillors backed the review of the percentage of reflection, but not at the expense of neighbouring residential areas. The aim of the review of the rule was that new buildings would not hold excessive heat.
