Purpose of a UDP
• Its purpose is to establish an effective methodology which identifies, prioritizes, and defines the cost for the current and future needs of all utilities to the year 2035
• A UDP is a comprehensive, long range, strategic plan encompassing all campus utilities. It is a companion to the Campus Master Plan
9
Develop a strategic utility infrastructure plan for the Facility that will support the growth objectives
defined by the Campus Master Plan and correct existing deficiencies. The utility infrastructure
renewal and system expansions are to be financed through reinvestment of utility operating funds
generated by efficiency improvements and utility cost avoidance, and by direct capital investment of
remote utility infrastructure fees associated with capital building construction and renovation.
• Identifies deficiencies by systems• Prioritizes needs in planning time frames• Identifies cost of corrective actions• Plans for the future• Accommodates change• Opens communication
• slow change can…
• Gets you organized

Value of a UDP
• Provides corrective actions to support your master plan
• Documents a collaborative process
• Provides ready reference for funding
• Establishes a roadmap for reaching goals and objectives
• Compels critical utility information to be compiled, organized, and accessible
• Nine aqueducts were built in Rome, providing some 150,000 cu m (38 million gal) of water each day. Parts of several are still in use, supplying water to fountains in Rome.

“Sanitation has its history, its archeology, its literature, and its science. Most religions concern themselves with it, sociology includes it within its sphere, and its study is imperative to social ethics. Some knowledge of psychology is necessary to understand its development and retardation, an esthetic sense is required for its full appreciation, and economics determine, to a large degree, its growth and extent…. Whoever, indeed, would study this subject with a knowledge worthy of its magnitude must consider it from all angles and with a … wealth of learning.”
Long distance power transmission lines made of composites are proposed.

UNDERGROUND HIGH VOLTAGE DISTRIBUTION
This chart is intended to be used for obtaining an initial estimate of required pipe size and cost. Actual system design must be based on values obtained specifically for the project. Total installed cost per linear ft. of buried supply & return (2 pipes) piping. Price includes trenching, insulation, fittings, backfill & moderate amounts of surfacing repairs. For total project cost add A-E fees, testing, escalations, contingencies, etc.
Ampacities shown are from the National Electrical Code, and are for underground ductbank, concrete encased, minimum 3 ducts. Multiple loop ampacities are reduced per the National Electrical Code. Cable is single conductor, shielded, 100% insulation level high voltage cable. Each duct contains 3 h.v. cables and a ground conductor sized per NEC.
A manhole every 500 feet.
Power factor is assumed to be 0.9.
For radial systems, building area power usage is estimated at 5 W/ft2.
For loop systems, building area power usage is estimated at 3 W/ft2 (central plant loads not included).
Cost does not include high voltage switch at each point of use ($15,000 each).

• 1907--Willis Carrier installed first air conditioning (temperature and humidity) in a Brooklyn printing plant which provided a stable environment for four color printing
• Carrier was earning a salary of $10/week at the Buffalo Forge Co.
GPM’s were selected to maintain water velocities (V) below 10 fps, and pressure drop (f) below 1’/100’ for large size pipes. The GPM values for smaller size pipes were selected to maintain water velocities below 7 fps, and pressure drop below 4’/100’. The velocities and friction drop values are according to Cameron. (C=100).
1000’s of gross sq. ft. of building are figured at 300 GSF/ton, I.e. (10,500) indicates that approximately 10,500,000 GSF can be air-conditioned with 35,000 tons. For heavy research areas use 220 GSF/ton.

Building SQFT values are based on 60 Btuh/sqft peak average combined load (building heat and domestic hot water). For winter lows below +25 F: at 0 F multiply building SQFT by 0.8, at -20 F multiply building SQFT by 0.6.
Steam lines are sized to approximately 10,000 ft/min.
Condensate lines are sized to approximately yield pressure drops less than 2’/100’.

Numbers shown are calculated for a nominal 100ft run of pipe. The energy delivered to the system may be estimated at 1040 Btu/CF. Therefore, a capacity of 20,000 CF cor-responds to (20,000 CF)*(1040 Btu/CF), or 20,800,000 Btu.
The cost to provide a boiler or other heating equipment to a stand-alone (no steam) building is approximately $2-$4 per square foot of building area.
