Who we are

The mission of the Historic Resources Committee (HRC) is to identify, understand, and preserve architectural heritage, both nationally and internationally. HRC is engaged in promoting the role of the historic architect within the profession through the development of information and knowledge among members, allied professional organizations, and the public.

We hope you'll join us February 7-8 at the annual HRC Taliesin Colloquium where we'll discuss how codes have impacted existing buildings and what to expect from upcoming code changes.

When Historic Buildings Meet The Codes
This presentation will look at what happens when repair, alteration, relocation or change of occupancy occurs with an historic building. It will examine the relevant chapters in the 2018 International Existing Building Code – Chapter 12, Historic Buildings – and the 2018 International Energy Conservation Code [Commercial Energy] and [Residential Energy] – Chapter 5[CE] and Chapter 5[RE]. It will look ahead to where the codes are going – a more holistic definition of Health, Safety and Welfare incorporating resiliency and sustainability. The need for active involvement in code development and the opportunities available will be explored. This session will incorporate powerpoint, include case studies, and provide question/answer interaction.

10am - Session 4
Melvyn Green, Principal, Melvyn Green and Associates, Inc.
Structural Provisions Related to Historic Structures
This session will cover structural aspects of the IEBC, alterations, rehabilitation, and seismic retrofit. It will discuss triggers that may require additional work than anticipated. The session will cover examples of repair of damage from natural disasters. Examples will include masonry and timber buildings from the 18th Century through the 20th Century. Retrofit requirements for concrete and steel structures will also be covered.


10:45am – Session 5
Amanda L. Webb, Assistant Professor, Department of Civil and Architectural Engineering & Construction Management, University of Cincinnati
Energy efficiency in historic buildings in an era without exemption
Exemption for historic buildings has long been at the core of preservationists’ approach to energy codes. However, recent policy developments suggest that this position is no longer tenable. This presentation examines the key challenges and opportunities presented by an era of increasingly ambitious energy policy and narrowing exemptions for historic buildings. First, the treatment of historic buildings in recent energy policies is reviewed, with particular emphasis on developments at the state and municipal level. Then, the challenges brought forth by these new policies are identified. Finally, the presentation concludes with a discussion of opportunities for leveraging these new policies towards a more proactive approach to energy efficiency in historic buildings.

11:25am - Session 6
Sean Denniston, Sr. Project Manager, New Buildings Institute
Energy Codes and Historic Buildings:  Recent Changes and Future Trends
The landscape of energy codes and policy has undergone a significant shift in the last few years with an increasing focus on existing buildings.  In 2015 the International Energy Conservation Code was restructured so that it more clearly and effectively addressed existing buildings. This restructuring redefined what would be considered a “historic building” for purposes of the code and eliminated the IECC’s previous categorical exemption for historic buildings and replaced it with a much narrower, conditional exemption. The result is that historic buildings would be far more subject to the energy code than previously. Another manifestation of this shift is the advent of Building Performance Standards that regulate the actual energy consumption of buildings. However, early examples, such as Local Law 97 in New York City, do not always include robust protections for historic buildings. The trend toward greater regulation of energy performance in historic buildings could be a serious threat to them. It could also be a serious benefit. This presentation will cover recent shifts in energy codes and policy for historic buildings as well as potential future changes. It will then examine how the preservation community can use this shift as an opportunity to preserve historic buildings, or allow it to become a threat.
