This new report “Buildings for the Climate Crisis – A Halifax Case Study” by Peggy Cameron, MES reveals the high levels of greenhouse gas emissions (GHGs) released up-front by high rise construction, developments, and demolitions. By comparing these to more climate-friendly in-fill buildings (carbon-neutral or carbon-positive) it offers scenarios that are better matched for what society and Earth need at this time.
For the report a Canadian interdisciplinary climate change strategy consultancy Mantle Developments, conducted preliminary estimates of global warming gases associated with:
— two Halifax based proposals;
— the associated demolition of 12-14 historic houses;
— the replacement of the demolished floor area, equivalent to a 12-storey building and,
— a 9-storey in-fill option modeled by the citizen’s group Development Options Halifax.
The report details impacts of the present developments and associated demolitions on the climate crisis and links this to the affordable housing crisis.
This report proposes options in the path forward including policy recommendations for what needs to change if we are planning for an inclusive society and for environmental remediation. With the release of this report the author aims to encourage all parties to seize this important and timely opportunity to re-think accepted practices of the building, construction, and demolition industry.
Globally, green houses gasses (GHG’s) from the materials and products used to build buildings is 11% as embodied or upfront carbon and approximately 29% as operational carbon from heating, lighting and cooling.
