Development<br />
�� Collaboration of 4 Partner Organizations<br />
�� �� Cooperation with with & Funding from DOE<br />
DOE<br />
�� Management via Steering Committee<br />
�� Volunteer effort (2250 - 5000 hours)<br />
�� Two Peer Reviews<br />
�� Educational Guidance – not a Standard
Goal<br />
�� A way, but not the only way to build<br />
energy gy efficient buildings g that use<br />
significantly less energy than a minimum<br />
code compliant p building g<br />
�� At least 50% energy savings as compared<br />
to to ANSI/ASHRAE/IESNA ANSI/ASHRAE/IESNA Standard 90.1<br />
2004<br />
�� �� 50% progress toward a net zero energy<br />
building

How do the the 50% 50% <strong>Guide</strong>s<br />
differ from the 30%<br />

Development<br />
�� Target market is contractors, designers,<br />
and design/build firms – 50% guides<br />
assume higher level of modeling expertise<br />
�� Easy y to use with prescriptive<br />
p p<br />
recommendation tables, “how “how-to” to” guidance<br />
and bonus savings g – 50% <strong>Guide</strong>s add<br />
“Performance” design strategies and/or<br />
energy gy targets g<br />
� 50% <strong>Guide</strong>s have stronger emphasis on<br />
integration g in design g
Development<br />
�� 50% savings determined using whole<br />
building energy savings<br />
�� <strong>Energy</strong> gy is independent variable & cost-<br />
effectiveness is dependent variable<br />
�� �� TSDs TSDs include sections on cost effectiveness<br />
�� <strong>Guide</strong>s recommend off off-the the-shelf shelf technology<br />
– must be available from at least 2<br />
manufacturers.
