Calls for NZ's building code to include energy efficiency rules

University of Otago researchers are calling for a change to the Building Code to enforce the construction of highly energy efficient housing.

In a recent study they say this could help New Zealand to reach its 100 percent renewable energy goal.

Lead author of the study, Associate Professor Michael Jack from the University of Otago's Department of Physics talks to Jesse about how the changes to the code would make a big difference.
