Getting Started Getting Started Start with what interests you
Use available resources to guide you- Energy Star, local green building programs, LIHTC regs
Pick a manageable and achievable number of strategies, systems,or materials
Minimize additional costs through integrated design, rebates, and grants
Learn from experience - repeat what works, change what doesn’t
Add a few items to each new project
