Name or title of the innovative policy, practice, program, or outcome:
Air Quality and Energy Efficiency
A brief description of the innovative policy, practice, program, or outcome that outlines how credit criteria are met and any positive measurable outcomes associated with the innovation:
The pandemic caused by Covid marked an important change in building management. From the moment it was shown that Sars-CoV-2 transmission occurred via aerosols (particles smaller than 100 µm that remain suspended in the air for varying amounts of time), and that transmission generally occurred in indoor spaces with inadequate ventilation, indoor air renewal became of crucial importance. One of the most significant preventive measures against Sars-CoV-2 is ventilation in order to ensure good air quality.
With the aim of providing all students, faculty and staff with a safe campus and peace of mind, our facilities have been adapted by increasing the air renewal rate in all classrooms, libraries, dining halls and other common areas.
The Operations Area’s concern was twofold: Increasing the air renewal rate and keeping heating and air conditioning energy costs under control.
• The supply of outside air at extreme temperatures incurs an additional cost in thermal energy. Energy overconsumption was estimated at > 15%
• According to health recommendations, implementing 24/7 ventilation involves high-cost overruns. Energy overconsumption was estimated at > 20%
To minimize this overconsumption while maintaining good air quality, the following solutions were adopted:
• The installation of Indoorclima’s SG AirQ management system, which optimizes indoor air regeneration by controlling CO2 concentration and temperature using Machine Learning algorithms.
• Adjusting the maximum ventilation rate to the capacity of each space, as per IDA2.
• Establishing model fitting protocols
• Air purifiers were installed in the air renewal ducts.
With the management system installed, the main control parameters are:
• Operating procedures: ppm CO2 concentration, °C temperature, % humidity
• Variables of the external environment: ppm CO2 concentration, °C temperature, % humidity
• Operating variables: % opening of dampers, % opening of valves, Hz of fans, etc.
There is continuous monitoring of environmental parameters with alerts sent to the technical team should CO2 concentration spike above 750ppm.
For the information of all Campus users, these environmental metrics are shared on monitors at the access door of each classroom, on monitors in common areas and with a QR code for access to the monitoring platform in meeting rooms.
The outcomes of this project are:
• Peace of mind for the entire IESE community
• Continuous adjustment of indoor air quality (CO2)
• Sustainable use of facilities
• Guaranteed comfort
• Savings of 19% in annual energy consumption
