When the City of Sammamish (WA) asked the design team to pro­vide a LEED® Silver certified building for the new city hall at the 25-acre Sammamish Commons redevelopment project, Notkin Mechan­ical Engineers believed IAQ was of paramount importance.

it seems that change is coming to the health care system in one form or another. Helping them keep their expenses down will be more crucial than ever. There also is a great deal of awareness of infection control, another area where mechanical systems play key roles.

CITY OF INDUSTRY, CALIF. Southern California Air Conditioning Distributors (SCACD), the world’s largest Carrier distributor, wanted to investigate additional indoor air quality (IAQ) improvement methods in its 30 year old administrative facility located here

Installed in HVAC systems, hogh-output UVC Emitters™ from Steril-Aire, Inc. provide a safe, effective method for microbial control in hospitals and healthcare environments.

Becoming a major gateway to green. That’s precisely what New Zealand’s Auckland airport’s newly remodeled international passenger terminal was tasked with in 2007. New Zealand’s largest commercial building, handling 13 million passenger movements per year, had a goal to reduce their carbon footprint by 5% before 2012.

The recent outbreak of the antibiotic-resistant superbug CPRK (carbapenem-resistant Klebsiella pneumoniae) in hospitals throughout the United States has put the patient population on alert once again regarding Hospital Acquired Infections (HAIs)

The facility rapidly became the source of complaints about poor IAQ and odors. An engineered solution that incorporates both an odor control unit and supplemental ultraviolet-C (UVC) lights in the air handlers has solved the problem and earned the project semifinalist status in the city’s prestigious Quality and Productivity Awards program.

Known as one of the world’s busiest airports, Changi Airport is working to prevent the spread of COVID-19 and its more transmissible variants
