Ron Geren Selected as Presenter for 2017 AIA Convention in Orlando, FL

Ron Geren has been selected by the AIA to present "Applying the Building Code: Step-by-Step Guidance for Architects" after submitting his proposal in response to AIA's Call for Educational Proposals in May. The education session will be a 4-hour pre-Convention session. The specific date and time has not yet been established.

The content of the presentation will be based on Ron's new book, Applying the Building Code: Step-by-Step Guidance for Design and Building Professionals (See below). The session will address each of the 28 steps presented in the book and cover some specific code issues that are frequently encountered during design. An example project will be utilized throughout the process to show how each of the steps are applied during the three standard design phases: schematic design, design development, and construction documents.

The book approaches code application from an entirely different perspective when compared to other books that explain the building code.  Other references for building code books follow the chapter structure of the code book itself with descriptive or illustrative explanations for the various code requirements. 

Applying the Building Code, on the other hand, explains in a step-by-step presentation, which code requirements should be looked at and considered during each of the standard design phases: schematic design, design development, and construction documents.  Further, the new book is not limited to just the 2015 International Building Code (IBC), but also includes applicable requirements from the International Energy Conservation Code (IECC), International Fire Code (IFC), International Plumbing Code (IPC), and the National Electrical Code (NEC) as applicable to the architectural design profession.

The book also provides an overview of the International Existing Building Code (IEBC) and how the step-by-step process can be modified to address projects associated with existing buildings.

To help explain the step-by-step process, an example project is used throughout the book explaining how each step is applied based on the information available at that phase.  As a bonus, a template for a code data sheet is provided in the appendix to help design professional organize their code information for incorporation into a set of construction drawings.
