106. SUSTAINABLE STRATEGIES
Path to
Net Zero

107. PASSIVHAUS APPROACH
Passivhaus as a Path to Net Zero

108. 1. Minimize Loads
• Insulation & Airtightness
• Heat-Recovery Ventilation
• Exterior Shading
2. Simple, Efficient Systems
• Minimized Loads allow Simple, Affordable Systems
3. Renewable Supply
• Loads can be met with Sustainable Energy Grid
• Net Zero within Reach (now or later)
• “Winter Gap” is minimized
PASSIVHAUS APPROACH
Passivhaus as a Path to Net Zero

109. Invest in this… …so we can heat like this
(especially when solar power isn’t there)
PASSIVHAUS APPROACH

110. Envelope Investment Opportunity
Residential Building Energy Use
We typically have one opportunity to address
40-50% of a building’s lifetime energy use
Building Component Lifespans
PASSIVHAUS APPROACH

111. Benefits
• Health
• Comfort
• Durability
• Resiliency
• Energy Savings
PASSIVHAUS APPROACH

112. PASSIVHAUS APPROACH
Impact on Design
