The Making of a Green Science Lab

Sustainable houses and office buildings have seen their popularity surge in recent years. But creating a more sustainable laboratory, especially one with chemistry research, where fume hoods can consume up to three times as much energy as an average home, is a bit more of a challenge.
On May 6, SERC broke ground for a new Mathias Lab with its own solar, geothermal and water recycling systems. Analysts estimate it will consume at least 37 percent less energy, and emit 37 percent less carbon dioxide, than a similar building that meets only the bare minimum requirements for LEED certification – the standard for green building. SERC staff are targeting LEED gold.
The old lab isn’t disappearing. The 21,000 feet of current lab space will undergo massive remodeling, while builders tack on 69,000 square feet of new lab, office and support space. A two-story atrium will connect the old and new sections and create a space where scientists from different departments can share ideas.
Because SERC scientists specialize in a multitude of disciplines – including global change, nutrient pollution and invasive species – having that interconnected space is critical for collaboration. The new lab will divide research into four research “guilds”: marine/estuarine and terrestrial ecology on the first floor, and environmental chemistry and cell/photo/molecular ecology on the second.
To leave a greener footprint, the new laboratory will include:
An HVAC system supplied by a large geothermal well field (250 wells 350 feet deep)
A 350-kilowatt array of solar panels on the renovated section to provide almost 14 percent of the building’s electricity
Constructed wetland made of a series of cascading pools lined with native plants, to help with stormwater management and runoff
A system to reclaim wastewater by cleaning it at an outside treatment plant and re-using it in toilets, gardens, fire suppression and the constructed wetland
Low-flow fume hoods for chemistry experiments
High-efficiency enthalpy wheels that recover energy from exchanged air
Bicycle racks and priority parking for carpools and high-efficiency vehicles
Solar panel recharging stations for electric vehicles
