The Challenges of Preservation

• The Building exists

• Integrated, sustainable design should be embodied throughout the form of the building

• In a Preservation/ Rehabilitation, we are retrofitting “Add Ons”


The Challenges of Preservation


• Integrated, sustainable design should be embodied throughout the form of the building

• In a Preservation/ Rehabilitation, we are retrofitting “Add Ons”

The Advantages of Preservation


• Older buildings often include forms and materials that allow for passive systems

• The “Add Ons” can make a big difference in building performance

• Baseline for calculating incentives is Existing Condition rather than Current Code


Sustainable Development and Rehabilitation

FIVE AREAS OF FOCUS

• Site Development

• Energy Conservation/ Generation

• Water Conservation

• Use of Raw Materials

• Healthy Living Environments


Influences on Strategies

• Resident Profile

• Cultural and Neighborhood Context

• Owner’s Mission/ Priorities

• Operational Challenges

• Project Budget


Evaluation Criteria

• Suitability to Existing Building

• Direct Benefit to Residents
