23 Scenarios Scenario name Description Cost [$] Space requirement [m2] Risk [credits] Innovation [credits] Business as usual No changes to ventilation or any systems. Risk to researchers due to systems not operating as effectively as designed. 0 NA 3 0 Partial implementation* Optimize airflow, minimal disruption to research. Reduce ventilation rates to appropriate levels based on risk assessment (LVRA) and repair airflow programming, including implementing occupancy controls. $5,000,000 $27/m2 NA 1 2 Full implementation* Optimize airflow and address equipment efficiency – potential for short-term disruption to research. Reduce ventilation based on LVRA and fix airflow programming, including implementing occupancy controls. Convert CV to VAV fume hoods and implement proper sash management. Relocate supply and exhaust grilles for optimal airflow. Install a Konvecta heat recovery system. Promote an efficient equipment procurement program, including water-efficient autoclaves to reduce hot water demand. $31,400,000 $174/m2 NA (Potential to reduce future space requirements) 1 3 *We assume MIT’s 5,500 labs will be steadily updated until 2050 at a rate of about ~220 labs per year.
