St. Louis jewel box building


The Jewel Box Forest Park

We assisted in the design and provided unique pedestal style 3 row X 3 tier perimeter radiation. 4 story glass walls required over 8,000 BTU’s/Ft to protect the plant life within. Special stainless steel wall brackets and cover were required to survive the humid environment. The Jewel Box is a St. Louis treasure.

Butterfly House - St. Louis zoo


The Butterfly House

A geodesic dome building with large heat losses, it was originally built with thin profile cast iron radiators. These rusted though rather quickly and looked terrible. They were replaced with stainless steel convectors, which stand up to high humidity and constant plant watering and continue to look great.



Busch Stadium

Ever wonder why you see players sitting up on the backs of the dugout benches in spring and fall? That’s because Sterling finned tube radiators running beneath the benches are providing heat to keep them warm. Special stainless steel cover and brackets hold up well to spit and regular washings, but sadly don’t fare too well when struck by the bats of the latest strikeout victims. Interestingly, we provided equipment for both dugouts, both dugout restrooms, but only the Cardinals bullpen. Guess we didn’t want opposing pitchers warmed up too quickly?

Crowder College


Crowder College

The Merit Center is one of the first Net Zero Energy buildings in the state of Missouri. Powered by wind and solar panels, it is heated and cooled by 4 pipe radiant panels we provided. Hot water is supplied by a methane biomass boiler with wood pellet backup and 58-60° chilled water for cooling is pumped directly from the ground.

This 100+ year old building was the second one built on the campus. It was completely gut rehabbed in 2011. Sterling Architectural perimeter heat was installed throughout.

Now mostly hidden due to it’s recent renovation, Sterling pedestal style hydronic heat keeps the 30’ tall glass on the south and east walls clear and warm, even in the coldest of weather.
