Energy use
Notice when your home is uncomfortable, expensive, or wasting energy.
Sustainable home
Make home lighter on the planet—and better to live in.
Start with comfort, efficiency, water, and materials. Then explore renewable electricity and the path toward a more self-sufficient home.
Comfort first.
Technology second.

A home learning path
One connected system
Energy, water, materials, and waste are not separate chores. Choose one thread and see what it teaches you about the rest.
Could solar work here?
Use a modelled estimate as a starting point for better local questions.
Heating & cooling
Comfort, shade, ventilation, insulation, and efficient systems work together.
Water
Use less, slow down rain, and learn what your local water system needs.
Batteries & off-grid basics
Understand storage and resilience before chasing independence.
Materials & repair
Choose durable, repairable, and lower-impact materials where you can.
Could solar work here?
A first look at your sunlight.
Choose a place and an approximate system size. PVGIS returns a modelled estimate of yearly output and seasonal shape — useful for a conversation, not a quote.
Self-sufficient, not isolated
Off-grid is a pathway, not a personality.
Solar, batteries, water storage, insulation, and food growing can build resilience—but each has a material footprint and local constraints.
