PROJECT OVERVIEWDrake Well Museum
• Site of the world’s first oil well, birthplace of the modern petroleum industry
• Located in Titusville, Pennsylvania
• Museum is undergoing renovations to improve the HVAC system and building envelope
Problem Definition
• Develop energy efficient HVAC system that meets Owner’s Requirements
• Determine heating and cooling loads
• Correctly size heating, ventilation, and air-conditioning systems
Project Constraints
• Comply with ASHRAE standards 55-2004, 62.1-2007, and 90.1- 2007
• Maintain 45% RH, 68-72˚F for collection spaces at all times
• Design must be flexible, sustainable, and achieve a minimum LEED Silver
• Temperature and humidity control must meet PHMC Category I criteria

Energy Efficiency
The VRF system has several key properties that substantially increases its energy efficiency.
• Heat recovery between outdoor units
• Simultaneous heating and cooling operation with heat recovery between indoor units
• COP of 5.0
