City of Mississauga Net Zero Studies
NET ZERO STUDIES
CLIENT: City of Mississauga
Creation of four decarbonization pathways for 59 buildings within the City's portfolio. Calculation of utility costs/savings and GHG reductions for each measure within each pathway.
The City of Mississauga has a goal to reduce its portfolio wide GHG emissions by at least 40% by 2030 and 80% by 2050. EE was hired by the City to create a roadmap to achieving net-zero that will inform future capital plans. The roadmap should provide innovative solutions that allow the City to meet their reduction targets, while also considering financial constraints, condition of existing equipment and facilities, changes in electricity emission factors and utility costs, and changes in weather trends due to global warming.
The City has identified 59 buildings from its portfolio that account for over 90% of the portfolio wide GHG emissions. These are the buildings that have been targeted for decarbonization.
EE developed four (4) decarbonization pathways for the 59 buildings identified by the city. The pathways include: business-as-usual (equipment replaced at end of life, opportunities with short paybacks, controls changes), measured retrofit (solar PV, renewables, some fuel switching (i.e. heat pumps) if the current electric capacity can accommodate), deep retrofit (opportunities with longer paybacks (or no payback), envelope upgrades, fuel switching (i.e. cold weather air source heat pumps, GSHP, VFF systems, that will require electrical upgrades)), best in class pathway (the most innovative measures currently available on the market to significantly reduce GHG emissions, for example, GHSP combined with energy storage and heat recovery).
Utility savings/costs and GHG reductions for each measure in each pathway will be calculated, as well as lifecycle costs. Lifecycle costs will include: life-span of equipment, maintenance and operational costs and future carbon costs and changes to emission factors. Financial parameters provided will include: cash flow, IRR, life-cycle cost per tonne of emission reduction, and NPV over a 50-year period.
