Impact of Victoria’s residential energy efficiency regulations

Here’s an interesting assessment of the success or otherwise of Victoria (Australia) energy efficiency standards for houses.

Concerns about negative impacts on housing affordability were therefore not substantiated, and there was no evidence of negative impacts on Victoria’s housing market.”

On the other hand design was a weak point. “While the average rating of new homes actually exceeded the five-star minimum by a clear margin at building permit stage, design responses to the performance-based requirements were sub-optimal.
