59 Holistic Approach to Passive Design Six Steps

60 Set Inspiring Goals Net Zero Ready BHAG: Big Harry Audacious Goal $13,000/yr $11,000/yr $9,000/yr $5,000/yr Net Zero EUI Arch 2030 EUI Energy Star EUI Benchmark EUI Regional Average Electricity Usage Natural Gas Usage Average Building (Energystar Target Finder 50) Likely Code Building Energy Star Architecture 2030 Net Zero with 50% Roof Coverage

61 Analyze the Climate Typical Building No Heating or Cooling Zone Cold Winter Design: ~5F Summer Design: ~93F

62 Analyze the Climate Optimizing Passive Solar

63 Analyze the Climate Optimizing Passive Solar

64 Analyze the Climate Optimizing Passive Solar

65 Analyze the Climate Optimizing Passive Solar

66 Analyze the Climate Optimizing Passive Solar

67 Analyze the Climate Optimizing Passive Solar

68 Loads vs. Energy Use Loads = Peak Power Requirement on worst day. Think acceleration power. Energy Use = Energy consumed over the whole year Think of spending on gasoline.

69 Energy use will follow naturally

70 Typical Design Condition

71 Typical Design Condition

72 Reduce Loads Summer Shading

73 Reduce Loads Mass Walls

74 Reduce Loads Thermal Mass

75 Zone Air Temperature Reduce Loads Thermal Mass Daily Temperature Swing

76 Reduce Loads Rules of Thumb: - 2x Floor Area - 3 Deep 1 thick simulated concrete slab Daily temperature profile applied to top surface

77 Reduce Loads Lighting Incandescent Compact Fluorescent LED

78 w/sf Reduce Loads Lighting UUFCO ~0.6 W/SF

79 Reduce Load & Energy Use Envelope Building Element Parameter 2010 Oregon Energy Code Proposed Building Percent Better than Code Roof Type Attic Insulation above roof Minimum Insulation R-21 R-38 Maximum U-Value % Type Lightweight Walls Minimum Insulation R-13 + R-3.8ci 42% Vertical Glazing Maximum U-Value Type Non-metal framing U-Value SGHC % Slab On Grade Heated Heated R-15 for 24 R-15 for 24

80 Choose Efficient Systems Variable Speed Air Source Heat Pump

81 Choose Efficient Systems Heat Recovery

82 Choose Efficient Systems Heat Recovery

83 Reduce Loads Thermal Comfort

84 Phase Changing Materials

85 Choose Efficient Systems

86 Choose Efficient Systems Radiant Heating / Cooling Floor

87 Anticipated Energy Use Energy Results $19,000 annual energy cost savings from code baseline

106 SUSTAINABLE STRATEGIES Path to Net Zero

107 Passivhaus as a Path to Net Zero PASSIVHAUS APPROACH

108 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

109 Invest in this so we can heat like this (especially when solar power isn t there) PASSIVHAUS APPROACH

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

111 Benefits Health Comfort Durability Resiliency Energy Savings PASSIVHAUS APPROACH

112 Impact on Design Deep walls and roof assemblies Walls = 19 R-value = 60 Roof = 28 R-value = 96 PASSIVHAUS APPROACH
