The document summarizes a presentation on capital projects and energy management. It discusses opportunities to improve envelope systems, HVAC, controls, lighting, and consider alternative/renewable technologies. Experts on the panel discussed benefits of brushless DC motors, building automation, LED lighting, and questions to consider regarding geothermal, co-generation, and renewable energy options like solar and wind. The goal is for audiences to think about energy efficiency of systems and how renewable energy fits their needs and energy mix.

7. DC Brushless Technologies
 Brushless technology extends motor service life
and reduces maintenance
 ECM up to 70% more efficient than PSC motors
 Variable Speed improves Acoustics
Fan Coil with ECM

8. Efficiencies
 On Permanent Split Capacitor
(PSC) motors, there is a
significant performance
degradation using multiple
speeds.
 Typical full load efficiencies of a
motor is 55-65% at the rated
voltage
 In part load, these efficiencies can
drop to 15-20%
 On Brushless DC motors, full load Typical full-load efficiencies for
fractional motors
efficiencies are 70% or better
 The real advantage of a brushless
DC motor becomes evident at part
load, where its performance edge
doubles or triples

9. Acoustical Benefits
 Motors can still be used with
traditional thermostats
 Soft Ramp between speeds
 Allows the transition between
speeds (H-M-L) less noticeable
by occupants
 Programmability
 Motor speeds (RPM) can be
adjusted for fan speeds (H-M-
L) to minimize acoustical
levels

15. • Directional light source
• LEDs are semi-conductors (non-filament source)
• Extended lifetime rating (>50,000 hours)
• Instant on (restrike times)
• Environmentally sound (no mercury)
• Cold temperature compliant – good for exterior
lighting
• Dimmable

16. • Wide range of:
̵Product quality
̵Claims of product life: from 50,000 hours to 100,000+
hours.
̵Efficacy: “my product is 135 lumens/W”
• Long testing procedures, energy efficiency programs
struggle to qualify products.
• Efficacy reached 200 lumens/W in a lab setting. Best
commercial products 60-80 lumens/W.
• Still more expensive than the
standard technologies.

17. • T5 is physically shorter and also
has a different pin base.
• Ambient temperature
significantly affects T5 and
T5HO lamp light output
• Both T5 and T5HO retain 95% of
light output at mean life, better
than T12 and most T8 lamps

18. • T5 and T5HO luminaries cost about 20% more than T8
luminaries.
• T5 and T5HO lamps and ballast are more expensive
• T5HO and T8 lamp-ballast systems have nearly
identical efficacy.
• T8 comes in more lamps-ballast
combination options: high
performance (“super”) T8
T
and reduced wattage T8 8
– more flexibility.

19. • Occupancy or daylighting based
- On/off
- Multi-level switching
- Dimming
• Passive infrared, ultrasonic, both
• Ceiling, wall or fixture mounted
• Wireless
• Scheduling Controls
• Most common problems:
- Misapplication
- Lack of or poor commissioning

21.  Alternative Technologies and Renewable
Energy Options:
What are the questions that you should ask
yourself and your peers before going there?

22.  GOAL:
“The goal is for the audience to begin to ask ourselves
questions about the energy efficiency of systems and
how does renewable energy fit into your energy mix”

23. Geothermal Systems (actually a
renewable – “The Earth”)
1. Why do I need a system such as Geothermal?
2. Do I have year around air conditioning needs
throughout my building(s)?
3. Do I need a new HVAC/Boiler/AC and distribution
system throughout my building(s)
4. How do I look at the economics associated with a
new system?
5. Full cost or incremental cost to upgrade?
6. Have I reviewed my control system capability?
7. What are the ground restrictions and quality of water
associated with drilling wells?
8. Is commissioning needed for the controls?

24. Co-Generation
 1. Do I have a heat sink?
 2. Will my utility rate schedule work with co-
generation/load reduction?
 3. What do I feel is a reasonable profile is for generating
electricity? It is generally not 24/7 more like 10-12 hours
per day for School buildings.
 4. Do you need back up generation for my building(s)?
 5. Does this size fit my load reduction size?
 6. Induction vs. synchronous?
 7. Am I going through an HVAC/Boiler system upgrade?
 8. How are my staff skills for performing some of the
routine maintenance requirements? Do you really want to
take this on? 24

25. Renewable Energy Options
1. What are my options?
2. PV, Wind, Biomass and Geothermal
3. What is the long term source of fuel for Biomass?
4. How can you make it fit into my energy management plan?
5. How can this “Program” within the school curriculum?
6. Are financial incentives available?
7. Are you expecting the Renewable energies to add
significantly to your energy reduction?
