1. GENERAL INFORMATION 1.1. UCF’s Utilities and Energy Services (UES) maintain the campus CHW production and distribution

system. These UCF Construction Standards are intended to identify any items that UCF UES

finds particularly important in maintaining a consistent and reliable system. These

requirements should be integrated into the project using the designer’s best professional, while

still meeting all Code requirements.

1.2. Chilled water metering (BTU and flow meter) is used to calculate utility billing, savings, demand

profiling, and performance monitoring for each building’s CHW service entrance(s). Essential to

these functions are an accurate, properly selected and installed metering systems. While UCF

UES will select and provide the meter, it is the designer and contractor’s responsibility to install

and integrate the components.

1.3. This information is not related to any CHW systems or sub-metering within a building.

1.4. If a chilled water service or application does not or cannot reflect the information in these

standards, please contact UCF Utilities & Energy Services directly for specific requirements.

1.5. For ease of use, this section of the construction standards provides multiple 8.5”x11” details or

Figures. These details are used to convey critical information to the designer, track the

designers progress and verify the contractor’s installation. These details or Figures are

provided in the table below and are intended to be incorporated into the construction

documents, by the designer, as applicable, after confirming they meet all current Code and

design intent requirements.

ALL Projects As Applicable

2. DEFINITIONS 2.1. Placeholder for future use.

3. TYPICAL REQUIREMENTS 3.1. Please refer to the Chilled Water Metering Responsibility Table in the attached Figures. The

table identifies the parties responsible for designing, providing, installing, terminating and verifying the metering equipment.

3.2. All chilled water metering systems installed at the university, main or branch campuses, must adhere to this Standard. The university does not accept substitutes for Chilled Water metering as Onicon is the university standard. (Div 33 UCF)

3.3. All buildings, new or renovated, that are supplied with chilled water shall be metered per these standards. (Div 33 UCF)

4. METER LOCATION 4.1. Placeholder for future use.

5. PLAN REVIEW AND COORDINATION WITH UCF UES 5.1. Coordination of chilled water service and metering requirements with UCF UES is important for

the success of the project.

5.2. At the 50% Construction Document Phase the following shall be shown on plans and reviewed

with UCF UES:

5.2.1. Proposed routing of CHW service from campus distribution loop to the building.

5.2.2. Proposed location of meter.

5.2.3. Proposed metering configuration.

5.2.4. Proposed heat rejection into the CHW system, CHW supply temperature, CHW return

temperature and volume.

5.2.5. Designer shall submit all included Figures identified by UCF for the service type. Designer

shall identify any aspects of the Figure that cannot or will not be provided.

5.2.6. All requested Figures shall be submitted to UCF UES, through UCF’s project manager.

5.3. At the 100% Construction Document Phase the following shall be shown on plans and

reviewed with UCF UES:

5.3.1. Final routing of CHW service from campus distribution loop to the building.

5.3.2. Final location of BTU and flow meter(s), including horizontal and vertical clearances.

5.3.3. Final heat rejection into the CHW system, CHW supply temperature, CHW return

temperature and volume.

5.3.4. Proposed point of connection and integration of the BTU meter to the building level and

campus level DDC system.

5.3.5. Proposed source of power for BTU and flow meter. This includes the panel name, circuit

number, circuit breaker size and location of electrical panel on the floor plans.

5.3.6. Designer shall submit all included Figures identified by UCF for the service type. Designer

shall identify any aspects of the Figure that cannot or will not be provided.

5.3.7. All requested Figures shall be submitted to UCF UES, through UCF’s project manager.
