At some point in time, many major corporations with central chilled water plants will make the decision to increase their chiller plant to accommodate their building campus expansion. For this month’s B2B, the corporation has chosen to add one 800-ton centrifugal chiller to its existing primary equipment (two 600-ton chillers and one plate-and-frame heat exchanger), so a Building Program (BP) is created, and this document will be the cornerstone for investing in an HVAC design and eventual construction of HVAC systems to meet the Building Program requirements.
For the HVAC engineer, he will take the program information and craft a Basis of Design (BofD) using the suggested BofD template here. For this month’s test, we have documented the BP for a central chilled water plant expansion within an existing chiller plant building. On page 2 of this B2B, the reader shall complete the BofD by filling in the pertinent data drawing upon the BP information provided and from pertinent reference documents such as local weather data design criteria. The answers to the BofD can be found here.
