How to Handle a 50% Increase in Occupancy While Maintaining Indoor Air Quality

ArcBest? is a logistics company located in Fort Smith, AR. Originally designed to support an occupancy level of 850 people, the 190,000 square foot corporate headquarters building has grown to now have 1,085 people plus visitors. The increase in occupancy drove the need for increased outside air ventilation, resulting in an increase in energy consumption and challenges in maintaining air temperature comfort throughout the building.

University of Miami

Improving Energy Efficiency and Indoor Air quality

Located at the University of Miami Miller School of Medicine in downtown Miami, the UHealth Fitness and Wellness Center occupies the top two stories of a thirteen-story building and spans 60,000 square feet. The indoor air quality (IAQ) was not at the level the facilities management team desired due to carbon dioxide (CO2) from people exercising, the equipment and mats off-gassing formaldehyde and volatile organic compounds (VOCs), and fine particulate matter from the nearby highway and airport.

Maximize Employee Performance While Saving Energy

The 44-story corporate headquarters building in the heart of New York City had been spending significant money cooling and heating outside air for ventilation, all while knowing that the outside air could no longer be considered “fresh air” due to high levels of air pollution. Further, numerous studies show poor indoor air quality (IAQ) directly impacts people’s productivity. Given the important financial decisions being made in the building, maintaining good air quality is a high priority.

Downsize Chiller Plant, Save Energy Expenses and Maintain Excellent IAQ in Hi-Rise Building

The real estate company owns an iconic 50-story high-rise building in the heart of a major city and wanted to decrease the energy consumption of its HVAC system while improving comfort at the same time. The air handling units (AHU) have a constant flow of outside air to ventilate the building. High energy consumption is required to condition the air in this seaside climate, with hot, humid summers. Improving energy efficiency, particularly during summer days, was a key driver as electricity costs are more than double during these peak demand hours.

Applying HLR Technology for a LEED Project at Zero Incremental Cost

The building, formerly a small museum, is being renovated and more than doubled in size to accommodate office space and meeting rooms. The original floorplan of 8,246 ft2 is being entirely renovated, except for the restrooms, bringing the total size to 21,848 ft2. The owner decided to target LEED Gold certification, under LEED v4 BD+C for new construction and renovations.

Defense Technology Company

Meeting Sustainability Initiatives While Maintaining Excellent Indoor Air Quality

With sustainability being a basic value underlying their business philosophy, the company turned to enVerid for help. The five-story, 120,000 ft2 office building is expensive to cool due to high HVAC energy consumption impacting utility costs. The HVAC system has twelve air handling units (AHU), with airflow ranges from 13,000 – 15,000 CFM. Learn how deploying HLR technology reduced electricity costs by 50%.

China Europe International Business School (CEIBS)

Preventing Polluted Air from Entering the Classroom

Large amounts of outside air were being brought in to reduce carbon dioxide (CO2) levels with the dangerous side effect of dramatically increasing indoor levels of PM2.5. The facilities management team wanted to maintain safe levels of CO2 and volatile organic compounds (VOC)

Pre-K to 12 Private School

Improving Cognitive Functions and Student Performance in the Classroom

It is generally accepted that high levels of air pollution and CO2 impacts cognitive functions and student performance. The school expressed desire to improve indoor air quality (IAQ) while reducing their high HVAC energy consumption for cooling.
