Project Overview

A 14-storey concrete mixed-use tower along Fraser Street with three levels of underground parking, combining 112 residential suites (Group C) over ground-floor retail (Group E) and a restaurant (Group A). Whole-building energy modeling was completed in IES-VE to demonstrate compliance with GBPRZ 2022 and VBBL Part 10 using the City of Vancouver weighted-area method; an NECB 2015 reference was created for the restaurant portion.

Cooling is provided in the primary bedroom of each dwelling via packaged terminal heat pumps with suite ERVs; the remaining rooms are verified through a formal overheating assessment. We evaluated every suite against the City of Vancouver overheating temperature criteria across summertime conditions and confirming compliance. Common areas are served by VRF make-up air systems, with VRF for CRU spaces and heat-pump domestic hot water; coordinated into a permit-ready package.
