2. What are we looking at?
Army is renovating it’s base barracks across US
Mostly Active Duty Bases, some Reserve Bases
Up to 500 dorms over the next 5 years
Increase Energy Efficiency
Comply with Federal mandates
90.1, 62.1, 189.1, LEED
Upgrade to current ventilation standards
Control the space %rh with a DOAS
Prevent or Remediate Mold
Upgrade sensors to monitor and control Humidity
Deliver between 43-48F dew points with 70-75F reheat
Thus, they need Munters DryCool systems

3. Active Army Base Locations: 500 Barracks

4. Request for Proposals Sent out by the Corp of Engineers, Ft Worth
Posted on
Dorms at a time
Issued to Multiple Task Order Contract (MATOC) General Contractors
GC assembles team to respond with design and energy analysis
US contracting office evaluates and awards the contract
Price is not main issue, but max price may be set
Compliance and Energy Efficiently are main criteria
Ft Polk, Volar Barracks
GC: Chicago
MEP: OKC
MC: Little Rock
So, need to get the word out that we have the solutions

5. - Design/Build - Barracks - 30% over 90.1
- Humidity Control

6. Basis of Award

7. Criteria

8. Understand the Specification
Must meet ASHRAE , and Table A
Exceed by 30%
Register and meet LEED Silver
Ventilation is set at 75 cfm per Living Area with 50 cfm EA
DOAS system to be used: Must be DX
Must use Enthalpy Wheel
Deliver 43-48F dew point
Deliver DryBulb at 70-75F
Space to be held at: Summer: 75Fdb 45% rh (max)
Winter: Fdb 50% rh (max)

9. Future May adopt one or more of the following:
Exceed by 40% (with plug loads)
Follow LEED 2012
Exceed by 30%
So we need to pay attention to these changes as they will only help us

10. Executive Orders
Net Zero Energy
30% Reduction

11. Recent Job: National Guard MS

12. Recent Job: National Guard MS
75 46F Dew Point

13. Recent Job: National Guard MS
OUTDOOR
INDOOR

14.
Because the spec calls for Energy Recovery, it is important to let contactors know that a standard Cool/Reheat system will not help them save energy

15. What about Energy Efficiency in Future
All States Must Adopt by Oct 2013

16. Climate Zone 60% TER Req’d Std. 189
Climate Zone % TER Req’d Std Design Air flow when >80% OA 1A, 2A, 3A, 4A, 5A, 6A, 7, 8 (Moist E. US + Alaska) > 0 cfm (all sizes require TER) 6B > 1,500 cfm 1B, 2B, 5C > 4,000 cfm 3B, 3C, 4B, 4C, 5B > 5,000 cfm

17. ~80% US population “A”
Climate Zone % TER Req’d Std Design Air flow when >80% OA 1A, 2A, 3A, 4A, 5A, 6A, 7, 8 (Moist E. US + Alaska) > 0 cfm (all sizes require TER) 6B > 1,500 cfm 1B, 2B, 5C > 4,000 cfm 3B, 3C, 4B, 4C, 5B > 5,000 cfm

18. Climate Zone 60% TER Req’d Std. 189
Climate Zone % TER Req’d Std Design Air flow when >80% OA 1A, 2A, 3A, 4A, 5A, 6A, 7, 8 (Moist E. US + Alaska) > 0 cfm (all sizes require TER) 6B > 1,500 cfm 1B, 2B, 5C > 4,000 cfm 3B, 3C, 4B, 4C, 5B > 5,000 cfm

19. Unit of Choice vs Cool/Reheat or Pinnacle
Low Dew Point + Energy Recovery + 30% savings =
DryCool ERV, 3 Fan HCU-ERV

20. Enthalpy Wheel + Desiccant

21. 75F/56 dp
75F/40.3 dp
7000 cfm and
20 tons
81F/61.5 dp
93F/68F dp
53F/53 dp

22. Top Points to make to Design Build Teams
Munters has experience and relationships with Corps
Price is not the determining factor, energy savings is
The baseline for DOAS is DX / Condenser reheat
Building must beat 90.1 by 30%
DOAS may be 50% of the energy usage
Can not get there with DX/Condenser Reheat
Can not get to low dew points with DX / Condenser reheat
Munters DryCool complies with all of the requirements
DX packaged system
Enthalpy Wheel option
Desiccant allows for low dew points and less energy that baseline, >30% in some cases

23. Point to Make vs. Cool / Reheat
Some teams may opt for the cheaper Cool/Reheat units: (aaon, valent, greenheck)
Cool/Reheat is the baseline according to 90.1
Adding an enthalpy wheel is in the spec, so no credit there
No energy savings to be gained with standard Cool/Reheat
Reheat may be required in some Temp Bins (energy use)

24. 4. DX coil sees 9% more airflow than Space = 9% more tons
Vs. Pinnacle
Heat in Summer
Delivery at 70-75F
SA Fan = 17% more airlfow than needed
EA Fan = 29% more air flow than needed
4. DX coil sees 9% more airflow than Space = 9% more tons
Dehumid is driven by Room %rh
Split System required and semco does not sell ACCU

25. Compare: Baseline vs. Munters vs. Semco

26. Conclusion Managing the decisions makers is difficult
Need to be first into engineer who are bidding
Show how DX/Cond reheat will not benefit energy
Show how DryCool Products will benefit
Become basis of Design Build Proposal
Munters is monitoring and in contact with the Corps of Engineers to find out when new jobs are coming out from bid
Munters will send leads to each rep office
Lead may be the GC, who we need to contact to determine his team
Contact both Engineer and Mechanical Contractor
Coordinate with cross territory reps
Rely on your RSM and AE and Scott McGinnis (Corps Contact)
Make Munters the basis for each design/build team bidding
