Loads vs. Energy Use

Energy Use = Energy consumed over the whole year Think of spending on gasoline.

SUSTAINABLE STRATEGIES

Path to

Net Zero

PASSIVHAUS APPROACH

Passivhaus as a Path to Net Zero

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

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

PASSIVHAUS APPROACH

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

Benefits

• Health

• Comfort

• Durability

• Resiliency

• Energy Savings
