What does a full-scale modernization on a 90-yr-old federal building and courthouse look like when it aims for federal energy goals and LEED status? Chiller plant and hot water/boiler overhauls are just the start. Aggressive lighting and water treatment/conservation strategies also contribute to the GSA’s effort to throw the book at this Alabama retrofit.
The USGBC has released its 2011 list of top 10 states for LEED®-certified commercial and institutional green buildings per capita, based on the U.S. 2010 Census information. The District of Columbia leads the nation, with more than 31 sq ft of LEED-certified space per person in 2011, with Colorado being the leading state, with 2.74 sq ft per person in 2011.
In this overview of building information modeling, the authors review how BIM helped in three different projects, often with particular usage- and efficiency-based HVAC demands. While BIM’s space management skills can reduce costly changeorders and building design “clashes” ahead of time, in at least one instance, using BIM actually influenced the HVAC strategy for the better, too. See how HGA Architects and Engineers has used this to become a “model” firm.

Platinum certification, the OSU Energy Center succeeded via consistently
efficiency-minded design and an exceptional level of analysis and teamwork in
the commissioning process. Fuel flexibility, staff training, and a projected
$650,000 annual savings didn’t hurt, either.
A VRF system installed in this University of Hawaii dorm helped the school achieve LEED® certification and lower energy costs. Founded in 1907, the University of Hawaii at Manoa (UH-M)
A VRF system installed in Guilford College’s Archdale Hall not only met architectural challenges but also provided high A/C performance.Established by the Quakers in 1837, Guilford College is the
Inside this nonprofit’s new headquarters in Portland, variable refrigerant
flow teamed with zonal heat exchange, 100% DOAS, daylighting, CO2
sensors, and more to deliver comfort while bringing actual energy
usage in under the design target of $0.83 per year.
