Designing & Building a Home as a System WELCOME! FACT: Buildings use close to half of the world’s energy production with many of our new buildings being no more efficient than those built more than a century ago. Throughout this Expo, we will explore: Site Planning Building Envelope Resource Efficiency Energy Efficiency Water Efficiency Indoor Air Quality

Designing & Building a Home as a System Last But Not Least Design & Build your home for your region Adobe construction not good for Midwest! Consider Universal Design for sustainability/longevity Good for resale- increases the number of buyers Use local products and native landscaping materials Usually a lower initial investment Helps the local economy, less shipping that can be better for environment Take the time to learn how to operate/maintain your home A well designed, quality home will fail if not maintained!

Last But Not Least

Design & Build your home for your region

Adobe construction not good for Midwest!

Consider Universal Design for sustainability/longevity

Good for resale- increases the number of buyers

Use local products and native landscaping materials

Usually a lower initial investment

Helps the local economy, less shipping that can be better for environment

Take the time to learn how to operate/maintain your home

A well designed, quality home will fail if not maintained!
