Our 2008 GOal
Implement energy, daylighting and material

TOPOGraPHiCal annual PrEvailinG Wind analySiS PROGRESS REPORT
With the full implementation of Revit across HOK
in 2008, the opportunities to expand the use of BIM
to drive sustainable performance has also grown.
Test 1: From South
Projects across HOK have begun to use Ecotect
along with other analysis tools to study climate and
weather analysis, daylighting, solar studies, and
energy use early in design.
In addition to project piloting, we focused in
2008 on identifying and testing a broad range of
available software to understand their project value
and validity. Tested software included Ecotect, IES,
Radiance, Daysim, & Green Building Studio. This will
lead to a recommendation of a suite of performance
analysis tools for broad rollout in 2009.

HOK’s progress.

Our 2008 GOal #1
Initiate measurement of HOK’s carbon
emissions in our offices and projects.
PROGRESS REPORT
After the Fall 2007 rollout of HOK’s Emissions: 2010
50% carbon reduction commitment, our 2008 efforts
first focused on identifying ways to measure HOK’s
carbon emissions. We successfully completed the
first carbon footprint benchmark of HOK’s practices –
looking at our offices’ energy usage, business air travel
and commuting. We also piloted in HOK’s Los Angeles
and St. Louis offices installations of energy sub-meters
that link to a live feed showing energy usage at day,
week and month intervals. HOK has learned a great
deal about the intricacies of live metering and are
exploring ways to expand and improve upon this pilot
for other offices.

A subsequent analysis is underway for 2008. A key finding
was that over half of our footprint was due to business air
travel. HOK’s implementation of expanded virtual meeting
technologies across the firm will help in reducing our air
travel carbon footprint.
