Frequently Asked Questions

What is sustainable architecture?

Design that reduces the environmental impact of a building over its whole life, through its orientation, energy use, materials and water, while keeping the people inside healthy and comfortable.

Why does building orientation matter?

Orientation decides how much sun reaches each facade and room. Placing living spaces, openings and shading with the sun path in mind can cut heating and cooling demand before any equipment is added.

What is biophilic design?

An approach that connects people with nature inside buildings, using daylight, plants, views, water and natural materials and forms. Our guides cover its patterns and how it applies to homes, offices, schools and hospitals.

What is the difference between Passive House and LEED?

Passive House is a performance standard focused on very low energy demand through insulation, airtightness and ventilation. LEED is a rating system that awards points across energy, water, materials, site and indoor quality.

Is the sun path diagram generator free?

Yes. It is free, runs in the browser and needs no account. It is hosted on our sister site learnarchitecture.net.
