New Website Features Coming Soon!

COSC is getting a new website with new features:

1. SUSTAINABLE RESOURCE DIRECTORY

A robust members-only area where resources are mapped and searchable by location, by business name and by category such as advanced framing, realtor, low VOC paints, HVAC contractor, salvage materials, etc. List your product or service in our valuable Sustainable Resource Directory by becoming a COSC member. Join today to be included in the launch! For questions or feedback, please send inquiries to our resource specialist Carrie Boyle at Carrie@icosc.com.

2. MEMBER LISTINGS AND THEIR EVENTS

The website upgrade will enable us to streamline and easily update our business member listings, which will be viewable by the public in alphabetical order for the non-profit member level and above. These members will also have the opportunity to have their events listed on our website and in our e-newsletters.

3. ONLINE EVENT REGISTRATION

Convenience at your fingertips! As we start integrating fee-based workshops into our programming again, attendees can register online and receive membership discounts on all class fees.

4. ASK THE EXPERT

A multimedia forum will highlight the knowledgeable resources we have in Iowa. Visitors can find useful sustainable building tips, share ideas and get their green project questions answered by local experts.

5. MEMBER PROFILES AND CASE STUDIES

We look forward to featuring stories about our diverse community of energetic members and the fantastic sustainable building projects happening throughout our state. Submit your ideas to Siobhan@icos.com.
