Approved Ruling: The reference dwelling glazing area used in the heat loss calculation method for terraces and apartments would be 30% of the internal conditioned floor area of the actual dwelling. The wall area would be the total external façade area of the actual dwelling minus this glazing area. Where the glazing area is higher than the actual façade area, the glazing area will be the façade area (100% glazing) For standalone dwellings this reference dwelling glazing area would remain 30% of total façade area as per NZS4218 and guidance to date. |
