An energy efficient designed building can reduce energy consumption by up to approximately 60% and water usage by approximately 30%. Meaning that in summer and winter, the building will be comfortable without significant air conditioning and artificial lighting. Hence, not only making it more comfortable, but saving significant amounts of utility bills.

The design of Punton's Apartments in Ivanhoe has achieved an 8 Star energy rating under the Nationwide House Energy Ratings Scheme.
