Evaluating HVAC Efficiency in Schools
To see how well heating and cooling systems (HVAC) work in schools, we need to look at a few important measures:
Energy Efficiency Ratio (EER): This tells us how much cooling the system provides compared to the energy it uses. A higher number means it’s better at saving energy. For example, an EER of 12 is better than an EER of 9.
Seasonal Energy Efficiency Ratio (SEER): This one shows how well the system cools over a whole cooling season. It takes the total cooling output and divides it by the total energy used in watt-hours. If the SEER is over 14, it’s considered very energy-efficient.
Heating Seasonal Performance Factor (HSPF): This is especially important in cold places. It measures how much heat a system produces compared to the energy it uses. A higher HSPF means the system is working more efficiently.
Coefficient of Performance (COP): This applies to both heating and cooling systems. It shows how much useful heating or cooling you get for the energy you put in. For example, a COP of 4 means that for every unit of electricity used, the system provides four units of heating or cooling.
Air Change Effectiveness (ACE): This looks at how well the HVAC system brings in fresh outdoor air while getting rid of indoor air, all without wasting too much energy.
By using these measures, schools can make sure their HVAC systems work well and help keep the environment healthy for both students and staff.
