Incrementalism is an inadequate approach to addressing energy and climate issues according to the author. The document discusses the need to dramatically reduce carbon emissions from buildings to mitigate global warming, noting that buildings account for 38-48% of energy demand. It advocates designing all new buildings to ultra-low energy standards like Passivhaus that can reduce energy use by 85% rather than more gradual efficiency improvements. Over 6,000 buildings have already been built to the Passivhaus standard, demonstrating it can be achieved with current technology.

2. Energy Matters!

3. Energy Matters! Transportation Industry Buildings

13. Incrementalism is Death ! We build today for 2050 and beyond.

14. Building Energy Benchmarks Example State of Minnesota Today 100% MN Energy Code 315 kWh/m2a -60% LEED Platinum 190 kWh/m2a -85% Passivhaus Standard 45 kWh/m2a

15. We can do it today ! Over 6000 Passivhaus Buildings have been build today

16. Let’s make the step together! I look forward to have a great dialog about ideas, experiences and challenges at this conference. THANK YOU!
