Columbia Univeristy’s recently opened Geochemistry Building at the Lamont-Doherty Earth Observatory was designed specifically to reduce energy usage in the high intensity laboratory environment. The facility features over twenty lab rooms, sixty offices, and support rooms, such as meeting spaces. Recommendation made by Community Environmental Center focused on recovering lost latent energy and accommodating partial loads without loss of efficiency. The laboratory has a 24 hour operation schedule, but will often be less than fully occupied. Highly efficient lamps and fixtures were installed to lower the overall lighting wattage, and advanced occupancy sensors are being used to eliminate unnecessary lighting cost. Energy Recovery Ventilation will operate during both the heating and cooling seasons. After analyzing cooling systems, CEC recommended a high efficiency air-cooled chiller along with variable frequency drives on the water pumps to allow them to operate efficiently at less than full load. Overall, CEC simulated seven different energy saving measures during both heating and cooling seasons, and expects the Gary C. Comer Geochemistry Building to save over $150,000 per year on energy costs.
