Integrating Beauty, High Performance and Red List Free Materials Cowhorn Vineyard + Garden Tasting Room COWHORN VINEYARD + GARDEN DESIGN DESIGN DESIGN DESIGN Path to Net Zero SUSTAINABLE STRATEGIES Passivhaus as a 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 Invest in this… …so we can heat like this (especially when solar power isn’t there) PASSIVHAUS APPROACH Envelope Investment Opportunity We typically have one opportunity to address 40-50% of a building’s lifetime energy use Building Component Lifespans PASSIVHAUS APPROACH Residential Building Energy Use Benefits • • • • • Health Comfort Durability Resiliency Energy Savings PASSIVHAUS APPROACH Impact on Design Deep walls and roof assemblies Walls = 19” R-value = 60 Roof = 28” R-value = 96 PASSIVHAUS APPROACH Impact on Design Breathable Envelopes in High Performance Buildings PASSIVHAUS APPROACH Details: Thermal Bridge-Free + Airtightness PASSIVHAUS IN DETAIL Details: Thermal Bridge-Free + Airtightness PASSIVHAUS IN DETAIL Details: Thermal Bridge-Free + Airtightness PASSIVHAUS IN DETAIL HVAC Systems for low-load buildings PASSIVHAUS IN DETAIL PH Challenges during Construction New Assemblies • Mock-ups • Pre-Construction Meetings PASSIVHAUS IN DETAIL PH Challenges during Construction Air-tightness • Signage • QC PASSIVHAUS IN DETAIL PH Challenges during Construction Avoiding thermal bridges • Sequencing • QC and Thermal Imaging PASSIVHAUS IN DETAIL Energy Model Results and Incentives • • 51% Energy Savings over baseline using code-minimal heat pump 68% Energy Savings over baseline using code allowed electric resistance PASSIVHAUS IN DETAIL LIVING BUILDING CHALLENGE LIVING BUILDING CHALLENGE Living Building Challenge 7 Petals | 20 Imperatives PLACE WATER ENERGY HEALTH & HAPPINESS MATERIALS EQUITY BEAUTY LIVING BUILDING CHALLENGE Materials Petal Endorsing products + processes that are healthy for all species through time • • • • • Red List Embodied carbon footprint Responsible industry Appropriate sourcing Conservation + reuse Results in cleaner air, cleaner water and healthier workers, inhabitants and wildlife LIVING BUILDING CHALLENGE Material Selection Strategy - Exterior LIVING BUILDING CHALLENGE Material Selection Strategy - Exterior LIVING BUILDING CHALLENGE Material Selection Strategy - Interior LIVING BUILDING CHALLENGE Material Selection Strategy - Interior LIVING BUILDING CHALLENGE Material Selection Strategy – Everything Else LIVING BUILDING CHALLENGE Process for Materials Selection MATERIALS PETAL IN DETAIL Process for Materials Selection ALTERNATIVES MATERIALS PETAL IN DETAIL Process for Materials Vetting MATERIALS PETAL IN DETAIL Process for Materials Vetting • • Dedicated staff member Initial reach out to manufacturers MATERIALS PETAL IN DETAIL Process for Materials Vetting • • Provide follow-up documents for ingredients list Documentation is key!
