Effectiveness Of UVC Technology For Improving School Performance


The potential benefits of installing the UVC EmitterTM is best estimated using a leading manufacturer's estimate of a 10% reduction in cooling energy when the UVC lights are installed on HVAC systems.  To estimate the potential energy impact in California schools from a reduction of 10% in cooling energy, we reference Tables 3 and 4 on page 17 in the CEC RFP 500-02-501 that lists the CA energy consumption and demand by end use and building type.

Table 3 shows the total floor area in California schools is 457.47 million square feet.  The cooling electricity consumption per sf-year is 0.74.  Therefore, an estimate of the total cooling electric consumption is 338.53 GWh.  If all schools in California had these UVC Emitters installed on all their HVAC systems, a 10% reduction in consumption would amount to approximately 33.85 GWh in energy saved per year.  No product will have a 100% penetration rate.  Therefore, we estimate that this mature product could have a 30% penetration rate after five years.  This would result in energy savings of 10.2 GWh annually. 

Table 4 also shows the total floor area in California schools is 457.47 million square feet.  The cooling demand per sf is 0.61.  Therefore, an estimate of the total California cooling demand is 279.06 MW.  A 10% reduction in consumption would amount to approximately 27.91 MW in demand reduction.  Applying the 30% penetration rate to the demand calculation results in a demand reduction of 8.37 MW.
