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
