This is an introductory slideshow about the Passive House building energy standard that I gave at the Passive House Minnesota event in Miinneapolis on 2/3/2011.
The slideshow contains a lot of full-screen images but no subtitles, therefore omitting some of the information which would have been given verbally during the presentation.
6. Certified Passive House™
TM
“A rigorous, voluntary building energy standard
focusing on highest energy efficiency and quality of life
at low operating cost.”
The Passive House Standard is the most rigorous building energy standard in the world. Consultants, projects or building components that have obtained
the right to carry the logo have committed themselves to design excellence and the Passive House energy performance criteria.

Sustainability delivered
To accomplish this, Architecture 2030 has issued The 2030 Challenge asking the global
architecture 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 implementing
innovative sustainable design strategies, generating on-site
renewable power and/or purchasing (20% maximum)
renewable energy and/or certified renewable energy credits.”
