Vancouver buildings to heat "green"
This past Wednesday, Vancouver City Council approved amendments to their building bylaw to bring down carbon pollution from new residential buildings to nearly zero.
The changes recognize that the biggest source of GHG emissions in Vancouver is burning natural gas for heating and hot water.
Starting in January 2022, all new buildings three storeys and under will be required to produce zero emissions from heating and hot water.
Other new buildings will be expected to move closer to Step 4 of the new BC Energy Step Code, starting in 2021.
The City expects these changes to result in 63% less carbon pollution than a typical home built to the current standards, and 86% less carbon pollution than a similar home built to the 2007 standards, which Vancouver is using as their baseline year.
The cost of these changes is estimated to be, on average, less than half of one percent of the value of the affected properties.
The building bylaw changes are part of Vancouver’s ambitious Climate Emergency Action Plan.
