=== Retrofit Proposal === | |||
This is a work in progress. | |||
==== Energy Savings ==== | |||
Energy savings are based on the reduction of seasonal energy usage (in kWh). The following assumptions are made: | |||
* All pool lights are operational; total consumption is 5000 W (500 W bulbs x 10 lights). | |||
* The lights are turned on 30 minutes before the calculated sunset time for 48154, calculated via [https://www.timeanddate.com/sun/@z-us-48154 timeanddate.com]. | |||
* The lights are turned off at: | |||
** 11 pm on Friday/Saturday. | |||
** 8 pm all other nights (before June 18th). | |||
** 10 pm all other nights (starting June 18th). | |||
* Early closures are not considered. | |||
This results in a total of 172 hours of theoretical usage for 2021, totaling 859 kWh. | |||
==== DTE Prescriptive Incentive ==== | |||
To be evaluated. Perhaps $170/fixture, $1,700 total. | |||
