4. The 2030 Challenge

efficiency vegetables before
you can have your renewable

7. Envelope
Remember, code is the minimum allowed.
It won’t get you to your goal.
Instead, start with ASHRAE’s Advanced
Energy Design Guides
Use energy modeling early to determine
performance goals.
Climate zones change requirements.
Breckenridge is different than Denver.
Optimize window selections for
orientations.
Look at new technologies. SIPs, ICFs, etc.

12. Controls
Can improve efficiency of
system, but won’t make up for
lost efficiency in envelope,
daylighting, or mechanical
systems.
Need to be flexible for future
technologies
Look at systems that integrate
all systems – lighting,
mechanical, and schedules.
13. Dilemmas
Gas versus electric?
Source Power: Do we design for the now (coal burning plants), or for the
future (renewable energy)?
Renewable energy sources – photovoltaic, wind.
Supply has gone up, but so has demand (and cost).
Limited control of the building performance after turnover. Energy
Star measures actual use.
Increase the education of our building users.
Include ongoing commissioning.

Final Thoughts
It reached the current (2008) goals of Architecture 2030.
Need to monitor ongoing performance and compare to model.
Projects started in the next two years will need to be even more
efficient to meet the 2010 requirements.
Eventually, we’ll need to include on‐site renewable energy (or
purchase credits) to achieve the requirements.
