Breathing New Life into Historic Marston Hall: A Success Story of Reuse and Renovation

This whitepaper by Lincoln Pearce, IMEG’s Commissioning Team Client Executive, discusses the challenges and successes the design team encountered while meeting and exceeding Iowa State University’s goals, including achieving LEED Gold certification, for the 60,000-sf renovation of Marston Hall, one of the oldest structures on the campus and home to the College of Engineering.   

The Laurel Rittenhouse Square: ‘Walking columns’ and other unique structural solutions

This paper examines the structural highlights, challenges, and unique solutions of The Laurel Rittenhouse Square, a 50-story, 583,000-square-foot residential tower under construction in Philadelphia. Written by IMEG’s Kirk Harman and Todd Campbell, the article was originally published in the June 2022 issue of STRUCTURE magazine, a publication of the National Council of Structural Engineers Associations (NCSEA).

ASHRAE Engineer’s Notebook: Water Treatment 101

This paper by IMEG’s Jeff Boldt and Joshua Ince, P.Eng., of DuBois Chemicals, summarizes the most important items for the HVAC designer to know about master specifications for water treatment, which is required on projects for many reasons. Reprinted with permission from ASHRAE, this paper was originally published as the “Engineer’s Notebook” in the March 22, 2022, issue of the ASHRAE Journal.

Acoustics and Indoor Environmental Quality

Dave Bodenschatz, IMEG Director of Mechanical Engineering, examines the importance of making noise control a consistent design consideration in the HVAC industry for all types of buildings. Reprinted with permission from the ASHRAE Journal, this article provides real-world applications in the use of acoustics design to help improve indoor environmental quality.

VA Electronic Health Record: Key Infrastructure Considerations for Modernization Projects

The U.S. Department of Veterans Affairs’ Electronic Health Record Modernization (EHRM) is being conducted through individual, campus-specific projects, all due to be complete in 2028. This paper provides a high-level look at key design considerations and strategies applicable to most EHRM initiatives, which in addition to software and hardware often involve significant building infrastructure upgrades or redesigns.

ASHRAE Engineer’s Notebook: Designing HVAC for Cold Climates

Successful cold-climate HVAC design depends on having the experience to know what items might cause problems or failures. This paper by IMEG’s Jeff Boldt and William Maki examines considerations for coils, pipes, and chillers, issues with snow, and occupant comfort. Reprinted with permission from ASHRAE, the paper is a follow-up to Designing HVAC for Humid vs. Arid Climates.

Lighting and acoustics in union: Enhancing environments through integration

Optimizing the impacts of lighting and acoustics by merging their designs is becoming more refined as the approach matures in the built environment—providing a dynamic range of concepts not seen in the past. This paper provides benchmarks and definitions for acoustics as well as design considerations for integrated acoustic luminaires. A case study with four

ASHRAE Engineer’s Notebook: Learning to Use Architectural Acoustics In Engineering

This paper by IMEG’s Jeff Boldt and David Wright introduces how room functionality improves with improved architectural acoustics, especially in rooms used for collaboration, instruction, and assembly where clear speech is needed. Reprinted with permission from ASHRAE, the paper is a follow-up to a previously posted “Engineer’s Notebook” explaining basic acoustic terms.

ASHRAE Engineer’s Notebook: Learning a Vocabulary For Acoustics Fundamentals

Current architecture trends favoring open rooms, hard surfaces, expanded daylighting, and exposed HVAC ducts have made acoustics design more important than ever, but much of the regularly changing terminology surrounding acoustics can be confusing. This paper, written by IMEG’s Jeff Boldt and David Wright and reprinted with permission from ASHRAE, offers a simple vocabulary of basic acoustic terms that are almost always considered in any type of project.

K-12 Security + Lighting: Notification and Safer Egress for Active Assailant Events and Environmental Emergencies

This paper outlines innovative early warning strategies that combine a K-12 building’s new or existing security and lighting systems to function as a notification resource during an active assailant event or environmental emergency. The goal is to show how one cohesive platform can detect and identify various threats and communicate their locations, probable areas of safety, egress information, as well as other helpful directives.
