Climate change has been the Region of Peel Councils priority for over ten years, the current term of Council priority is ‘Build Environmental Resiliency’ and is a key part of the Regions Strategic Plan. Greenhouse Gas (GHG) emission reduction is an essential part of the Regional Climate Change Master Plan where buildings are identified as one the largest emitters of GHG.
The Arcadia Glen housing complex is located at 6025 and 6045 Glen Erin Drive in Mississauga. It is generally comprised of two 3-storey townhouse blocks which are connected through an enclosed bridge and consists of 81 units total with two levels of underground parking. The townhouse blocks were constructed in 1981 with renovations and restoration
projects completed since related to the siding and fascia.
CES was responsible for managing a multi-disciplinary team through phases 1 to 5, covering Investigation and Pre-Design, Design Development, Construction Contract Documentation, Procurement, Construction Administration, and Warranty/Closeout. The main objective was to electrify all gas-fired mechanical equipment to achieve GHG reduction and energy
efficiency. To support this objective, CES Engineering developed and proposed retrofit measures using full lifecycle costing and dynamic energy modeling. These models, calibrated to each building’s baseline energy data, were organized into Design Solutions (0-4), each aimed at specific targets like GHG reduction and CaGBC ZCB Certification, along with incremental costings to aid Peel Living in the selection process.
The final selection process balanced innovative solutions with practical, cost-effective measures. CES ensured that the designs met GHG reduction targets while remaining financially feasible by considering lifecycle costs and long-term benefits. This approach led to a forward-thinking, yet budget-conscious scope of work outlined below.
- Gas fired MUAs replaced with air source heat pump (ASHP) MUAs
- Domestic hot water (DHW) plant renewal with CO2 air source heat pumps (ASHP)
- Electrical baseboard heaters within apartments replaced with high efficiency PTACs and ERV units
- Domestic cold water (DCW) pipework replacements
- Sanitary and waste pipework replacements
- Provision of upsized 1500 kVA utility transformer
