BartonSolvents

Barton Solvents

Des Moines, Iowa

Design+build of a new 37,500 square foot flammable storage/mixing/filling facility.

Big Barn Harley-Davidson

Big Barn Harley-Davidson

Des Moines, Iowa

This project involved the design+build of a new 34,000 square foot specialty retail space. Design was to encompass the look of a rustic Iowa barn with the latest features of modern ventilation. A variable-air-volume (VAV) system was sized and zoned for sales area, parts and services counter and the company’s office space.

We were challenged to produce ductwork to match the aged galvanized ductwork already in place. After experimenting with various metal finishes, our shop was able to match new duct to the existing look.

Big Barn presented a second challenge – detecting and managing carbon monoxide in the shop while maintaining proper air pressure in the showroom and ensuring that no odors crossed from the shop to the showroom. We accomplished this goal by using a simple, yet effective 80/20 MAU with integrated DX coil, carbon monoxide sensors, differential pressure sensors and simple logic controls.

MidwestHealthcareTextiles

Midwest Healthcare Textile Services

Des Moines, Iowa

This design+build of a new 54,000 square foot industrial laundry facility project included an extra twist which required us to meet the American Institute of Architects (AIA) Guidelines for Hospital Construction, which includes certain ventilation rates and airflow movement between soiled and clean areas, plus summer cooling for occupants on a non-profit organization’s budget.

To satisfy these requirements, ventilation rates and pressure differential were maintained with the use of constant volume and variable volume MAUs. We also used spot cooling by converting off-the-shelf rooftop units to 100% outdoor air units. Typical construction included HVAC, plumbing, process piping and exhaust.

ScottishRiteMasonicTemple

Scottish Rite Masonic Center

Des Moines, Iowa

SME Mechanical provided a design+build renovation of a 33,000 square foot space that required the addition of air-conditioning. Fresh-air ventilation was delivered by conditioning outside air to neutral conditions (74 degrees at 45% relative humidity) and moving the air through the existing un-insulated warm air ductwork system. The existing duct system was impossible to modify because of its location behind historic granite walls. Constant volume units were installed to provide space-cooling occupied zones.

This LEED Silver ™ 5,250 square foot office space offered the challenge of proving LEED points with a building of less-than-typical heating/cooling load for a variable volume system.  Our design+build solution included a custom air-handler with three-coil intertwined coil, hot water heating and integrated energy recovery ventilator. Innovation & Process (ID) credits were received for this project.
