16. Benefits Of CHP 16
Typical off-­‐site fossil fuel power generation
Power generation efficiency 35%
Line loss (from source to site) 5%
Delivered on-­‐site efficiency 30%
Modern high efficiency CHP plant
75 to 80% efficient
Reliable on-­‐site electrical and thermal energy source
Ability to supply campus during power interruptions
Higher efficiency reduces energy consumption & cost
Significant reduction in emissions and carbon footprint

17. CHP Analysis & Justification 17
$73.25 million capital investment
$6 to $10 million projected annual cost avoidance
(actual cost avoidance determined by cost of energy)
Simple payback of less than 10 years
$10 million DOE grant awarded to TAMU
Reduced energy consumption and emissions
Improved:
reliability of service
redundancy and emergency power source
sustainability with reduced carbon footprint

Server Room Consolidation & Virtualization
21
21
Pilot program:
CIS, UEM and College of Engineering worked together to
virtualize and consolidate 28 server rooms to Teague
- Scheduling of HVAC systems in Engineering alone will
avoid of $65,000 annually in HVAC energy cost
- All components in place for virtualization of servers
- Need to close the deal with final scheduling of space
Campus-wide opportunity:
Over 300 server rooms located across campus prevent
scheduling of HVAC systems opportunity for significantly
improved IT service and energy efficiency

22
$15 million project budget in 23 facilities
3.3 million GSF of research/teaching/office space 18 bldgs
3.5 million GSF of lighting 5 parking structures
Upgrade building automation systems and lighting
Funded with a low interest loan (2%) from State of Texas
Reduced annual electricity consumption by 10,000 MWh
Reduced annual thermal energy by 66,000 mmBtu
Improved service with payback of less than 10 years
