About CEIBS

The China Europe International Business School (CEIBS), a joint-venture for management education, was co-founded by the Chinese government and the European Union (EU) in 1994, with Shanghai Jiao Tong University and the EFMD serving as its executive partners. CEIBS offers China’s largest full-time English-taught MBA program, the world’s largest EMBA program, stand-alone Global EMBA, as well as a part-time Finance MBA program, a range of Executive Education programs and an intensive Ph.D. program.

Academic Center IV, the main teaching venue, is a three-story, 5,500 m2 building containing lecture theaters, lecture halls, discussion rooms and administrative offices (See Figure 1). The first-floor lecture theater accommodates 80 students, has an area of 190 m2 and an average height of 3.7 m.

The Challenge

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 (VOCs) without drawing so much polluted outside air.

Solution

It is generally accepted that high levels of air pollution and CO2 impacts cognitive functions and student performance1, 2. CEIBS expressed the desire to improve indoor air quality (IAQ) and turned to enVerid Systems for help.

The enVerid project team assessed the HVAC mechanical environment, provided a detailed installation plan, and selected and supervised electrical and mechanical subcontractors with the customer’s approval. Installation of one enVerid HVAC Load Reduction (HLR) module was completed during summer vacation without disrupting HVAC operations.

80% Reduction in Outside Air and Improved IAQ

IAQ monitoring was performed per the US Environmental Protection Agency (EPA) standards. Samples were analyzed and certified by a highly-respected US-based lab (PRISM Analytical Technologies).

The HLR solution maintains healthy indoor air at full occupancy (see figures 2, 3 and 4).
