Here is a look at the latest Basis project. Helping to give the Jungle Building a new lid!

Jungle Roof

 

This new semi-transparent ETFE "Foil" roofing system presented many design challenges for the MEP engineers. The roofing system is made up of pressurized layers of Ethylene tetrafluoroethylene or ETFE for short. These layers form insulative pockets with thermal and solar properties similar to multipaned windows.

The second part of this project was a wholesale mechanical system replacement. The existing system consisted of eight air handlers, located one in each of the eight towers. These air handlers were supplied by a well system in the cooling mode and a boiler in the heating mode. The entire system was well beyond its useful life and in dire need of replacement. 

The new mechanical system consists of six gas fired packaged rooftop units and two dedicated outside air units. Each unit will contain UV lamps and MERV 11 filters to control contaminates in the airstream (great for the animals!). The new system will take advantage of the existing structure louvers for a low return and new soffits for a high discharge. Ideal for air circulation and maximizing airflow through foliage to prevent disease.

With the increased cooling load on the mechanical system comes an increased electrical load. We took this opportunity to bring a new Westar feed into the building. This allowed us to relocate the major equipment to a more accessible location within the building and build in a connection point for an emergency generator.

This project provided the nearly forty year old SCZ Jungle Building with a much needed update that will breathe life back into the building for years to come.

 We would like to thank GLMV Architecture and the Sedgwick County Zoo for letting us be a part of this project.
