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

Summary of Pros and ConsRecommended
Option 1 Option 1A Option 2A Option 3 Option 4A Option 5
2 Taurus 60s, 600 psi combined cycle with
one 150 psi steam turbine driven chiller
2 Taurus 60s, 250 psi combined cycle with
one 250 psi steam turbine driven chiller
2 Taurus 60s, 250 psi HRSG with one steam turbine driven chiller
