Products and Services Directory
We like to think of this as our virtual, open year-round exhibit hall. The IDEA Products and Services Directory is an innovative, online searchable database that connects you with manufacturers, suppliers and service providers who can partner with you on your next project. Consistently one of the most visited pages on our website, only member companies are eligible to be listed in the directory. So, if you’re a manufacturer/supplier/service provider looking to find your next customer, you need to be here.

IDEA Exhibit Hall
An integral part of our Annual and CampusEnergy conferences, the always sold-out IDEA Exhibit Hall features all the top manufacturers and suppliers in the industry. If your system is looking for a new partner – or if you’re a manufacturer/supplier looking to offer your services – this is the place to be.


IDEA Membership Directory
IDEA keeps members connected through this unique online communication portal. The IDEA Membership Directory allows you to search for members by multiple criteria including keyword, company name, location and more. Found who you’re looking for?

Whether you’re crowd-sourcing solutions, gathering opinions, or just looking to discuss a hot topic, IDEA Connect gets you in touch with the right audience to help. If you don’t have a question, hop in and see if you can lend your expertise to an existing conversation.
