Longwood Medical Area – Boston, MA
Founded in 1922
Building1st Floor
•1st Floor square footage: 4,554
•Total square footage: 85,382
Project Statement
Issues
• Inefficient space ventilation
due to Constant Volume HVAC
systems.
• Inefficient use of lighting.
• Non adjustable furniture.
Proposed Solutions
• Reduce air changes per hour and
implement occupancy scheduling.
(Occupied/Unoccupied)
• Evaluate new lighting technology
and sensors.
• Alternative modular lab furniture
systems.
*(Above solutions contribute to decreasing Green House Gas’s for the Building)*
Deliverables
• Project Task Schedule
• Estimated budget:
• Simple Payback
• Detailed specifications of current and proposed equipment
• Cost /savings of proposals
• Proposed floor plan layouts

Analysis Of Savings for The LR6 LED Lighting Overview
Aircuity Ventilation Rate compared to
Constant Rate
“However, under normal operating conditions, room air
is typically clean, and a lower ventilation air change rate
would be acceptable. Diluting clean room air with clean
supply air achieves no benefit and wastes significant
amounts of energy.” – Aircuity Reasoning
