12.4
Target 12.4: Hazardous waste generation
Indicator 12.4.2 is hazardous waste generated per capita and proportion of hazardous waste treated, by type of treatment.
Responses 1. Exhaust ventilation system reduce the generated pollutants into the environment. 2. Passive ventilation reduces the air-condition usage and hydrocarbon refrigerant is used in most of the air conditioning system as it is non-toxic and has no ozone depleting properties.
Challenges The engagement and participation of user within the university and the amenities provided poses a challenge as the designer needs to provide and fulfill the standards and protocols listed as their safety and health and wellbeing are the number one priority.
Contributions Exhaust ventilation system Constant extraction of air to keep the air clean and fresh. Exhausting fumes and channels commonly installed in the kitchen and bathroom helps to reduce the generated pollutants off the spaces with negative pressure implied. Figure 8.1 is an exhaust ventilation system where the indoor air is continuously extracted to the outdoors with one or more fans often located in the bathrooms. Mechanical extract system is mostly used in bathrooms and kitchens where there is a need for constant extraction of contaminated air.
