Climate Mat

Welcome Radiant

Climate Mat delivers the advantages of radiant heating and/or cooling within a package that increases affordability and labor-efficiency for mid- and large-scale jobs. Unlike typical radiant tubing installations, which require that individual lengths of tubing be extended and attached to a sub-base, it is a tubing module which permits the installer to simply roll out as many as six equivalent lengths of tubing simultaneously. Advantages over typical installations include reduced installation time, tubing securement method guarantees desired tubing spacing, pre-pressurized tubing eliminates downtime, pre-engineered design taking the guesswork out of installation and no balancing needed due to

Hawaii Tackles Affordable Housing with HVAC Solution at Kapiolani Residence

With affordable housing availability a problem in Hawaii, the state is incentivizing developers to tackle the issue. Hawaii’s cost of electricity for the residential sector is the highest in the nation—currently 2.5 times the national average—so it can be heavy burden on households that are already struggling.When developer Timothy Yi, President of Samkoo Pacific & Samkoo Hawaii, set out to build the 45-story Kapiolani Residence in Honolulu, Hawaii, he wanted to provide an affordable housing option with enhanced functionality and modern design. And part of its affordability had to be keeping utility costs low for residents as well.

McCormick Place's Rapid COVID-19 Alternate Care Facility Conversion

In record time, Stantec and Walsh Construction delivered 300 beds for low-acuity patients and moderate-acuity COVID-19 patients to relieve capacity in the City of Chicago’s hospital system. Directed by the U.S. Army Corps of Engineers, in association with The Metropolitan Pier and Exposition Authority, Environmental Systems Design was brought in for the mechanical, electrical, plumbing, medical cases and fire protection, and Thornton Tomasetti took care of the structural design.Fortunately, the convention center’s large open halls and regularly spaced in-floor utilities—power, data, water and drains—were ideal for setting up bays of patient spaces. Further, in the low

Electronic Air Measuring Station

At AHR, Ruskin introduced a truly novel product, the AIRFLOW-IQ, which combines the features of the company’s TDP05K air flow and temperature measuring probes, with its CD50 control damper and the VAFB24-BAC RAMS Air Measurement BACnet actuator. The factory-assembled and calibrated unit provide effective setpoint airflow control from 0 to 5,000 FPM (0 to 25 m/s) using analog or BACnet interface. The ultra low-leak, class 1A-rated CD50 damper helps satisfy the requirements for minimum outside air as required by ASHRAE 62.1, 90.1 and 189.1, California Title 24, the Int’l Mechanical Code and the Int’l. Energy Conservation Code. According to the manufacturer, one of the ma
