Architectural Principles in the Age of Sustainability

1.Use less energy – a lot less2.Make the energy you use3.Make it local4.Make it simple5.Make it multifunctional6.Make it last 7.Make it personal and beautiful

Definition: Net zero energy building

The energy produced by on-site renewable energy is equal to the energy consumed by the building.

(Energy Consumed) - (Energy Produced) = ZERO Energy

2. Make the energy you use


So little energy is consumed that we can actually get to Zero with the addition of renewable energy
