This month Lab Design published our article about the next generation laboratory and the evolution of laboratory design. We’ve shared an excerpt of the piece here, along with graphics that illustrate the paradigm shift in lab design.
Payette has played a signature role in the evolution of modern labs through consistent innovations and a long tradition of designing influential science and research buildings. More recently, the key components that inform the next-generation lab are an aggressive stance towards energy conservation, a flexible armature that can easily accommodate shifts in research density spanning from a Principal Investigator (PI)+4 to a PI+10 planning module and an integrated approach for computationally based research.
The Biosciences Research Building (BRB) at the National Univ. of Ireland, Galway (NUIG), currently pursuing BREEAM (Building Research Establishment Environmental Assessment Methodology) Certification of “Very Good” (equivalent to LEED Platinum), is one of Payette’s most recent examples of innovation in energy conservation and building performance. The building employs a high-energy/low-energy sustainability strategy, which places the most mechanically intensive spaces, such as tissue culture and imaging suites, into a zone adjacent to the traditional open lab space. As a result, high-energy use spaces that are densely occupied can have direct access to the natural light at the building perimeter. Low-energy use spaces, such as writing carrels, offices and interaction spaces, are also grouped along the perimeter to optimize natural ventilation and daylighting strategies. The building has the lowest energy profile of any major research facility Payette has designed, with 50% of program areas naturally ventilated. Initially programmed for a PI+6 baseline, the building has been occupied at a density of PI+9 and is thriving. Through a rigorous post-occupancy evaluation process that explores multiple projects, we have learned which high-performance energy and programmatic strategies really work and why.

To execute a revolutionary design for lighting a research laboratory, Payette proposed the creation of a new LED task light. In lieu of traditional under counter lighting that can be blocked by equipment, the team designed the new fixture to attach to the leading edge of an extended upper shelf, positioned to provide optimal illumination while casting the smallest shadow.

High-energy/low-energy plan organization. The BRB at NUIG wraps the perimeter of the building in a low-energy “thermal sweater,” which is 100% naturally ventilated for cooling. High-energy open labs and lab support (writing desks, offices, public spaces) are insulated by the thermal sweater and are cooled/heated mechanically. (Click image to enlarge.)

Northeastern EXP features an organic pinwheel design, shaping research and classroom neighborhoods with shared community spaces radiating from the core to define each area. The building façade was tuned to achieve a 78% reduction in peak solar heat gain and a 62% reduction in cumulative solar radiation leading to energy use reductions and reduced mechanical system sizing. The use of stainless steel further leads to an embodied carbon reduction of almost one million tons when compared to aluminum while the natural stainless surface reflects light in a natural and warm tone giving the building an inherent energy.
