by Deborah Mesher, Architectural Designer and Carolyn Moss, Architect and Net Zero Consultant
Deborah: What is Net Zero (for residential projects)?
Carolyn: Everyone is talking about Net Zero. Though definitions may differ, the intent is to reduce greenhouse gas emissions in an effort to address climate change. For homes, this means a house that is energy efficient, uses renewable energy for power and does not burn fossil fuels - ie no propane, oil or ‘natural’ gas.
Deborah: What are the main barriers to achieving Net Zero while retrofitting existing homes?
Carolyn: One of the biggest problems is a lack of awareness. Most homeowners and even allied professionals like realtors, designers and contractors, are not aware of coming regulations. In Toronto, all existing homes will need to be Net Zero (or close to it) by 2040. Anyone doing renovations a home today should incorporate Net Zero planning.
Deborah: What are changes or upgrades you think every homeowner should plan for before they renovate?
Carolyn: We all need to go electric. If you have gas in your home for heating, hot water, cooking etc, it has to go. Insulation, air sealing, and high performance window and doors will help reduce the amount of money you spend on utilities. Solar panels can help offset electricity costs and provide more resiliency. The order that these improvements are completed in needs to be well thought out and sequenced.
Deborah: What do you wish more homeowners knew about Net Zero?
Carolyn: Your home will NEED to be Net Zero. Understanding what Net Zero means and how to get there is really important. But, rest assured, with a bit of guidance - your home can get there! Also - there are currently government incentives like rebates and loads to help make the transition - take advantage of them while you can!
Deborah: What are you most excited about that's emerging in your field?
Carolyn: So many things! I’ve been working with homeowners to make beautiful and sustainable homes for over 25 years - the pace of change in recent years has been incredible. I believe there are solutions to the climate crisis that will create an amazing world we can all thrive in.
