Tom,
Per my phone message, here is the current information on the snowmelt
for you to review. I will have additional cost estimates and plans on
Monday. Once I receive them I will drop them of to you. VRDC and the ,
Arrabelle team look forward resolving this issue at Wednesday meetting`�
Thank you for your cooperation and attention to this matter

Matt,
The attached PDF contains a simple payback analysis for adding
insulation below the TOV snowmelt.
The annual energy cost savings is $3486/yr
The installation cost is$43,000
The simple payback is 12.3 years
We did not perform a simple payback analysis for the controls system.
It appears the alleged benefits of the DDC controls are primarily
operational and not energy related. The TOV snow melt system runs east
to west between tall buildings and is substantially shaded throughout
the day. There is not a significant diversity on the system due to
sunny and shady spots to allow individual manifold control to realize
energy savings.

Re: Snowmelt System Operation Costs

Per meeting with 42/40 regarding the snowmelt system,Jack Hunn(Vail Resorts Devel. Co)had
asked about potential operating costs for snowmelt systems.The following information is from the
Beaver Creek Snowmelt system(now 94,000 s fl.Costs vary depending on the average daily
temperature,as well as gas rate increases(winter 2000-01):
Year Thermal Units Thermal Unit Cost Gas Cosdvear Gas$/sf/year *Total$/yr(indudes all)
99-00 158,469 varied,$.43-$.52/unit $69,317 $0.73/sf/year S0.&t/sf/yr
00-01 250,789 varied,$.58-$.85/unit $183,266$I.90/sf/year 52.�1/sf/yr
01-02 167,339 varied,$.45-$.42/unit $74,257 $0.79/sf/year $0.90/sf/yr
*Fairly consistent annual costs:
Electric$5279/year
Water $360/year
Phone $420/year
Annual Service contract $3800/vear
Sub-total $9859/year=$0.11$/sf/year
If you have any questions,please call.
