Where We are Going
A Three Step Solution
AFFILIATED ENGINEERS, INC.
Step One Go Away from Buried Steam Pipe
After 2 years the water is gone but …
CORROSION
FROM THE
SALT WATER
LEAKS
Move to Buried Hot Water
With Corrosion Resistant
Valves and Fittings
AFFILIATED ENGINEERS, INC.
Step Two Elevate the Boilers and Chillers
Impact of Ike…It could have been far worse !
AFFILIATED ENGINEERS, INC.
Step Three Produce On-Site Electricity via Combined Heat & Power (CHP)
Combined heat and power systems are approximately 50% more efficient than traditional systems
AFFILIATED ENGINEERS, INC.
Options Given Consideration
• On October 28, 2010 the
Facility Steering
Committee directed UTMB
Infrastructure Team to
proceed with increasing
the energy security of the
UTMB Campus
