Great West Life; Central Chiller Plant Expansion and Tower III Design; Englewood, Colorado – Project Manager of HVAC, Plumbing, Fire Protection and Electrical design and Project HVAC Engineer. The total project budget is 24 million dollars with a mechanical and electrical budget of 8.8 million dollars. The project included redesign and expansion of the existing chiller plant from 1200 tons to 2400 tons to accommodate Tower III and provide back-up capacity. Tower III is a 248,000 square foot design with ten stories above grade an one below grade. The design was changed from the first two towers to low e windows and to a blow through fan system to provide added capacity for substantially increased personal computer loads within previously determined structural constraints. Mechanical systems included chilled water storage, hydronic economizer, back-up systems, temperature control system replacement and upgrade and fire and life safety smoke control systems.
Great West Life; Mechanical And Electrical Systems Evaluation; Englewood, Colorado – Project Manager of HVAC and Electrical and Project Mechanical Engineer for systems analysis project. The basic mechanical task was to evaluate apparent central chilled water plant capacity shortages and to recommend a the size for an additional chiller. There were a number of unexpected findings which led to additional requirements for the Tower III design. The air handling systems were short of capacity for the owners current and projected needs. The chillers were used to create tenant condenser water which drained much needed capacity. The chiller and air handling unit cooling coil design temperatures were mismatched resulting in capacity loss. The automatic emergency mode for depletion of chilled water storage had no provision for loads less than full chiller output. The cooling coils were not pumped and chilled water was returning to the central plant with only a fraction of the capacity having been used. This rapidly depleted the chilled water storage. A heat exchanger with glycol had been added to solve a freeze-up problem but reduced the supply air temperature a few degrees in the Fall and Spring. Alternative solutions to these and other problems were recommended and solutions were agreed upon with the owner.
