Harvard scientists are all for collaborating when it comes to research. But when it comes to saving energy in their labs, the competition can get fierce.

Whether it’s closing fume hood sashes when they’re not in use or adjusting freezer temperatures, researchers in labs across campus are setting the sustainability bar higher for each other through friendly contests. And their steps are paying off — a building-wide energy-efficiency project at Northwest Labs alone is projected to save $900,000 a year.

2 Professor Christina Woo works in her lab, which has been upgraded with equipment that meets high sustainability standards, including the most energy-efficient freezer on the market. New fume hood controls conserve energy by reducing airflow when not in use.

5 The Weitz Lab is partnering with the Green Labs program to assess the energy use of lab equipment. Pictured here are Biyi Xu (from left), associate researcher at Nanjing University; Kirk Mutafopulos, GSAS physics student; and Pascal Spink, a research fellow in applied physics.
6 GSAS student Cristin Juda works in the Betley Lab, where a recent renovation incorporates cutting-edge sustainable technology and green building features that aim for LEED certification.
7 Using gas chromatography and mass spectrometry, researchers in the Northwest Labs analyze trace residues on ancient vessels found in Turkey. A building-wide energy-efficiency project at the labs is projected to save $900,000 a year by adjusting ventilation and airflow levels.

9 Alex Su ’18 works in the Betley Lab, which participates in an expanded lab recycling program while consistently meeting its monthly goal through the Shut the Sash Competition. In addition, lab members reduce waste by composting in their kitchen.

The Hoekstra Lab recently won the national North American Laboratory Freezer Challenge in the academic division, saving energy costs and reducing emissions by taking steps like tuning their freezers to minus 70 C from the standard minus 80 C.
