Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Presentation Outline Presentation Outline • Project Description • Cladding System • Mechanical System • Green Building • Summary & Conclusions
Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Project Description Original Mechanical System • Dedicated outdoor air system with parallel radiant panel system • Ventilation system – temperature control, air quality, and latent (moisture) load • Radiant panels address remainder of sensible load (temperature)
Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Mechanical System Redesign • Original Design • Estimated Cost = $1,500,000 • Did not consider structural effects of locating boiler and chiller on roof – additional $200,000. • Revised Estimated Cost = $1,700,000 • Redesign • 100% Outdoor air – geothermal system • Estimated Cost = $1,500,000
Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Mechanical System • 100% Outdoor Air – Geothermal System • Energy-efficient • Environmentally clean • Cost effective • Minitab Geothermal System • 40,000 lf of pipe – 100 wells @ 400 ft. each • 278 high-efficiency heat pumps • Air to air heat recovery system
Geothermal Well Field Individual heat pumps for each space above the ceiling in the corridor. Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Geothermal System
Erin E. Hess Construction Management Senior Thesis Project Minitab Headquarters Mechanical System Geothermal System • Maintain energy efficiency • Maintain indoor air quality • Maintain service load requirements • Eliminate structural and architectural redesign • Cost Savings = $200,000
