Oceanic Plaza Curtain Renewal Study

RJC Engineers was engaged as the building enclosure and building energy consultants for the curtain wall renewal study of Oceanic Plaza, an impressive 26-storey office tower in Vancouver’s Coal Harbour area.

With its 403,000 sq. ft. of space accommodating 1,100 occupants, the tower stands as a cornerstone of the city's commercial landscape.

The main objective of this study was to investigate the energy performance of the existing building, and to identify system modifications and/or synergies that could aid in reducing overall building energy consumption.

As such, a “whole building energy model” was performed using the energy modelling software program, IES VE 2019, and was calibrated based on the available utility data.

A detailed energy and Life Cycle Cost Analysis (LCCA) was conducted across three scenarios: double-glazed, triple-glazed, and double-skin façades.

This assessment not only identified the most cost-effective strategies but also laid the groundwork for long-term sustainability and improvements in operational efficiency.
