Indianapolis Headquarters

Our headquarters, located in the revitalized Capitol Corridor of downtown Indianapolis, was designed to intentionally integrate MEP features into the building’s architecture. The unique look and approach to efficient design also created for a visually appealing and productive workspace.  When the building opened, it was awarded merit awards by the Indianapolis Chamber of Commerce for innovative reuse in a rehabilitation and interior design topping some of the most premiere construction projects in Central Indiana.

The building’s mechanical system is unique, incorporating the latest in energy efficient, low maintenance and sustainable design. The core of the building is conditioned by a water-cooled Variable Refrigerant Flow (VRF) system. The perimeter and some conference rooms are served by Active Chilled Beams, which require only 23% of the fan driven airflow of a typical Variable Air Volume (VAV) system, resulting in astounding  fan energy saving.  An innovative liquid desiccant dehumidifying air handler with air pretreated by an enthalpy core heat exchanger provides the ventilation air for the building and the primary air for the Active Chilled Beams. An efficient Water-Source Heat Pump with hot gas reheat for humidity control serves the Training Room. The water-cooled system is cooled by an eco-Fluid Cooler, designed to save 92% of the water used by a typical fluid cooler.

An open protocol control system provided by Open Control Systems ensures that the HVAC, lighting and security systems are optimized and gives the owner real time and historic data to make sure the investment in these systems achieve their full value.

Evapco Fluid Cooler

• Designed for 100% dry capacity at a dry bulb switch-over temperature of 67.9F, there’s no need to waste water to cool the fluid from the building whenever the outdoor temperature is less than 67.9F
• Calculated water savings of 92%, annually using only 7,163 gallons of water, compared to 94,984 gallons of a typical induced draft closed circuit cooler

ConsERV Multistack Energy Recovery Unit

• 2000 cfm of outdoor ventilation air, 1900 cfm of building exhaust air
• At winter design of -10F outside, this unit raises the outdoor air temperature to 43F, and helps raise humidity in the dry outdoor air by adding 36.1 lb/hr of moisture
• At summer design of 95F outside, this unit cools the outdoor air to 81.8F and removes 26.7 lb/hr of moisture
• There is no cross-contamination of the outside and exhaust air across the enthalpy cores

Liquid Desicccant  for Ventilation and Primary Air

• Liquid Desiccant Air Handler provides low dewpoint primary air to Active Chilled Beams serving the perimeter, and ventilation air to the rest of the entire building
• Direct and independent control of humidity and temperature means there’s no need to overcool and reheat, saving 20-40% of the energy associated with outside air high latent mechanical systems and 30-60% over solid wheel desiccant systems
• The non-toxic liquid desiccant solution acts as a biocide by scrubbing the cross flow air of microorganisms and bacteria

Water-Furnace Heat Pump for Training Room

• The first 30 EER and 5 COP rated water-source heat pump on the market
• Hot Gas Reheat and Humidistat

Water-Furnace-Water-to-Water Chiller/Heater

• This dual refrigerant circuit unit is capable of providing either hot water or chilled water to the Active Chilled Beams

Dadanco

• Unique patented induction nozzle provides over four times as much supply air as primary air with very little air pressure drop, no fan and virtually no noise
• Models include traditional 2×4 lay-in ceiling style units, and architecturally pleasing concealed bulkhead-mounted style units
• Inffusers increase ventilation effectiveness and comfort by delivering twice as much air as the air that is ducted to them

LG – Variable Refrigerant Flow (VRF) system

• Water-cooled VRF with an IEER of 22.9 and a COP of 4.48 permits synchronous cooling and heating in different zones at the same time
• 17 various indoor unit types provide zoned temperature and humidity control
