International Institute of Building Enclosure Consultants (IIBEC) is an international nonprofit association of professionals who specialize in roofing, waterproofing, and exterior wall specification and design. 

From sprayed polyurethane foam to cedar shakes, from parking garages to air barriers, IIBEC has a member expert for every type of roof, exterior wall, or waterproofing issue in the world today.

Mission Statement: The mission of IIBEC is to advance the profession of building enclosure (roofing, waterproofing and exterior wall) consultants.

Since 1983, IIBEC’s, formerly RCI, Inc., Consultant members have offered unbiased design, repair planning, quality assurance observance, legal testimony, and general roofing and other building enclosure management services. IIBEC’s Consultant members adhere to a strict code of ethics that offers unprejudiced service without affiliation with any product or manufacturer. Current membership is over 3,600. IIBEC boasts an international constituency residing across the United States, Canada, Australia, the West Indies, Europe, and Asia.

The association presents educational programs, in-person and online, designed to demystify and explain the practical application of roofing and waterproofing technology and sound building enclosure theory. A monthly journal (Interface), a monthly newsletter (IIBEC Newsfeed), and international, regional, and chapter events provide interactive forums for information exchange and networking.

The Registered Roof Consultant (RRC®), Registered Waterproofing Consultant (RWC®), Registered Exterior Wall Consultant (REWC®), Registered Roof Observer (RRO®), and  Certified Building Enclosure Commissioning Provider (CBECxP®) coming in Spring 2020 programs distinguish professionals with proven standards of education, experience, and ethics. Individuals with all three consultant accreditations (RRC®, RWC®, and REWC®) may apply to be Registered Building Envelope Consultants (RBEC®). The RCI-IIBEC Foundation (U.S.) and the RCI Foundation Canada are tax-exempt entities, organizationally independent of the association, and support research and educational efforts of the industry.
The IIBEC mission is realized by a professional staff headquartered in Raleigh, North Carolina and through the efforts of a volunteer board of directors, numerous committees and its individual members across the globe.

We invite you to discover more about IIBEC and the professional path of its members. Whether you are a current IIBEC member, a nonmember professional, or a building owner or manager seeking a qualified referral, please browse our website or contact IIBEC headquarters at 919-859-0742 or 800-828-1902.

C-PACE Financing: An Innovative Tool for Commercial Roof Improvements

When: December 5, 2023 @1:00 – 2:00 PM ET

C-PACE – or Commercial Property Assessed Clean Energy – is a financing solution that connects building owners with 100% financing for project costs related to existing building energy efficiency and renewable energy improvements.The financing is secured by the building with long-term repayment plans, up to 30-year terms, which are added to the property’s tax bill. C-PACE financing programs are now active in over 30 states and the District of Columbia with additional jurisdictions expected to adopt authorizing legislation or launch programs soon.

As C-PACE programs continue to gain familiarity across the country, the innovative financing solution has been used increasingly to underwrite roof improvement projects on commercial buildings. These projects include both energy efficiency improvements as well as rooftop solar installations. Join C-PACE program administration experts to learn more about this attractive financing tool and how building owners and roofing professionals have deployed its benefits to improve building performance.

Learning Objectives:

1. Understand how C-PACE financing works and why its 100% long-term benefits are a compelling solution when coupled with roofing projects.
2. Identify which states and jurisdictions currently operate C-PACE programs and where new programs are under development.
3. Explain how C-PACE financing can be used to underwrite roof improvement projects on commercial buildings.
4. Learn how to increase your knowledge on C-PACE financing and how to stay current on program developments in the areas you do business.

Presenters:

• Brian McCarter, CEO, Sustainable Real Estate Solutions (leading C-PACE program administrator)
• Tracy Phillips, Director, Colorado C-PACE Program
