Certified Passive House™ TM“A rigorous, voluntary building energy standardfocusing on highest energy efficiency and quality of lifeat low operating cost.”The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have obtainedthe right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.

TM Metric vs. PrescriptiveEnergy per square foot and year gas mileage for buildings
TM Space conditioning limit ≤ 4.75 kBtu/(sf a) ≤ 15kWh/(m2 a) total energy used to heat or cool a building
TM Source energy limit ≤ 38 kBtu/(sf a) ≤ 120kWh/(m2 a) all energy consumed; accounted for at the source
TM Air tightness limit ≤0.6 ACH50 measured with blower door in the field

TM Sustainability deliveredTo accomplish this, Architecture 2030 has issued The 2030 Challenge asking the globalarchitecture and building community to adopt the following targets: • All new buildings, developments and major renovations shall be designed to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type. • At a minimum, an equal amount of existing building area shall be renovated annually to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type. • The fossil fuel reduction standard for all new buildings shall be increased to: • 60% in 2010 • 70% in 2015 • 80% in 2020 • 90% in 2025 • Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate).“These targets may be accomplished by implementinginnovative sustainable design strategies, generating on-siterenewable power and/or purchasing (20% maximum)renewable energy and/or certified renewable energy credits.” Source: architecture2030.com
