14 Cost - Cost of partial: $849,447,811 (~ $6.6M per building, $502 per m2 of TFA / $47 per ft2) - Cost of full: $2,577,299,872 (~ $26.3M per building, $1,994 per m2 of TFA / $186 per ft2) The estimated cost includes construction expenses such as removal of existing systems, staging, remediation costs, labor, construction management costs and design contingencies. Costs from disruptions (such as downtime, relocation, and vacancy), and soft costs are not accounted for. Additionally, costs associated with not retrofitting are imminent and relevant with approaching local regulations (BEUDO). Due to tax parcel deliminations, most buildings on MIT campus will be subject to fines in the coming years, which can increase costs further. This could incentivize a more rapid retrofit rate across campus buildings. [2] Building systems are not modelled explicitly. Heating and cooling loads assume a coefficient of performance of 1.
