Cost Effectiveness
From the DOE-2 energy simulation, the energy savings are
$144,896. All the energy efficiency measures, water management
and improved indoor air quality cost $1 million more than
a standard building. Even with features with no payback (water
management and improved air quality), the simple payback is
less than seven years.
From economic studies on this project, the return on investment
for the energy efficiency over costs is less than three years.
The budget overrun after construction was only 2.5%. Expected
subsidies from Hydro-Quebec are close to $500,000.
