Persistence Payoff: Post-occupancy fine-tuning helps Manitoba Hydro Place achieve its goals. - Kuwabara Payne McKenna

Getting all the systems integrated was no mean feat, however. During its first winter, both the boilers and the heat pumps were working more than twice as hard as the models predicted (see graph), and occupants weren't proactive about opening their windows. Spurred in part by the promise of a $1 million bonus for achieving the project's energy goals, the design team worked with Manitoba Hydro's engineers in commissioning and fine-tuning the operations of the building for a full year after it opened. Much of that process involved figuring out how the systems were actually working, then adjusting control settings to improve their efficiency. The team used smoke tests to learn, for example, that air in the double-wall plenum was not mixing as they expected, so when occupants opened their windows they were getting outside air directly. This allowed the team to increase the hou...
