Overview of the Illinois Energy Conservation Code for Commercial Buildings (20 min)
In his introduction, Dave Richmond provides an overview of the Illinois Energy Conservation Code. He introduces basic general energy efficiency concepts while explaining why energy efficiency and energy code compliance are important to the State of Illinois.

The State of Illinois adopted the change to the new Illinois Energy Conservation Code because doing so will result in commercial buildings with improved energy efficiency as well as other environmental, comfort and health benefits. In addition, building professionals will find a simplified plan review process and more standardized inspections.

The new Illinois Energy Conservation Code applies to new commercial construction as well as new construction, alterations or additions to existing buildings or spaces. A change in occupancy also requires application of Illinois Energy Conservation Code requirements.

Building components that must comply with the new Commercial Energy Code include the building envelope, mechanical systems (including HVAC) and lighting systems.

Basic Requirements: Building Envelope (35 min)
The building envelope describes the thermal boundary between the conditioned and unconditioned spaces of a structure. Basic building envelope requirements cover moisture control, air leakage and material identification. This segment provides a high-level overview of how building professionals can design and construct a building that controls moisture at its source while meeting Illinois Energy Conservation Code requirements.

Speaker Dave Richmond talks about how the new Illinois Energy Conservation Code dictates use and installation of sealants, air barriers, and other treatments. He also covers prescriptive requirements for various building assemblies in the building envelope itself.

Basic Requirements: Mechanical (15 min)
Since mechanical systems consume 35% to 50% of the total energy used in a commercial building, they hold significant potential for energy savings. Through smart design, building professionals can cut energy costs significantly, simply by 'going beyond the code' and by using innovative products and systems.

The Illinois Energy Conservation Code encourages efficient mechanical design by establishing requirements for equipment efficiency, ductwork, system controls and ventilation. This segment describes the differences between simple systems and complex systems while illustrating the code requirements that are common to both. Speaker Dave Richmond discusses some of the equipment efficiency requirements of various mechanical systems. He also covers ventilation, insulation and other topics.

Basic Requirements: Lighting (12 min)
One of the areas most affected by the new code is interior lighting. This segment covers basic energy code requirements for lighting controls, switching and exterior lighting, including exit signage. It also covers connected power requirements based on total wattage, occupancy type and other factors.

To determine compliance, building professionals must consider both total connected power and the power budget for the entire building. The building meets code requirements if its total connected power is no greater than the interior lighting power. Speaker Dave Richmond discusses criteria for exterior lighting power; he also discusses the energy-saving benefits provided by daylighting.

ASHRAE 90.1 (17 min)
As Dave Richmond discusses the key elements of ASHRAE 90.1, he reminds viewers that they have the ability to use either this or the Illinois Energy Conservation Code to demonstrate compliance with the commercial energy code requirements.

Revised in 2004 to improve its ease of use, ASHRAE 90.1 is structured similarly to Illinois Energy Conservation Code in that it considers the building envelope, the mechanical/HVAC systems and lighting. New sections now address building rating systems such as LEED to provide a framework for a performance rating methodology.

This section also covers the inspection process, covering requirements for pre-inspection, foundations, framing and insulation and the final inspection. Finally, Richmond lists 15 ways that building professionals can cut energy costs by as much as 50%.

Illinois Energy Conservation Code Code (15 min)
Jerry Crabtree, from the State of Illinois' Capital Development Board, presents an overview of the new Illinois Energy Conservation Code. He describes the history of the change, making sure to note that the new code applies to any commercial building or structure in Illinois for which a building permit application is received by a municipality or county. He also notes that the code applies only to those portions of a structure that are being added to, altered, renovated or repaired.

Although the Illinois Energy Conservation Code 2000 (with a 2001 Supplement) is the state's official energy code requirement, information discussed throughout this site often refers to the Illinois Energy Conservation Code 2004. However, to avoid confusion, the 2000 code is the legal minimum required for compliance.

Local authorities having jurisdiction must establish independent procedures for enforcing the Illinois Energy Conservation Code.
