This presentation demonstrates a methodical
approach that Page used to target net zero
energy use for a multifamily project. While the
individual strategies used for a multifamily
project will differ from those employed for other
building types, the strategic and tactical
approaches toward achieving the best return on
investment are applicable to any building
project
Course

Create the Team
To create a conceptual framework to implement vision
- Client, Architect, Energy modelers, Engineers, Cost Estimators
Utility representatives, Vendors
- Find people with the ability to think/understand issues outside of
their area of expertise - Interdependence of systems
- Get team together early – available for brainstorming
