light bulbs

Every April, Fenn boys take to the field at the same time as the Red Sox. But instead of swinging bats and hitting balls, we are swinging our arms at hitting light switches!  The Fenn community goes on the lookout for lights, computer monitors, and projectors that have been left on in empty classrooms and common spaces around campus.  It sounds like a minor thing, to turn off one bank of overhead lights for an hour; but it does add up on our campus, throughout the buildings and over the course of the school year.  Our Buildings and Grounds crew has done great work installing energy efficient systems and relamping areas of campus, and our boys support that work by using those devices smartly and conservatively.

How to Play

We're Going by Building This Year!

We are monitoring the lighting and wall plug load in each of the five buildings this year.  The building with the greatest reduction in average load over the three weeks of the game (as compared to the past two months) will be declared the winner.

What about the Baseball Part?

Advisory groups have a chance to demonstrate their energy-saving prowess by scoring hits (and thus runs).  For every hit a group records, you are one base closer to scoring a run.  The most enthusiastic and active advisory group this spring in their own building will receive a special recognition.

Building Territories

We're able to monitor five areas of our campus with special electricity monitoring devices.  Where your advisory group meets in the mornings is the space that you are responsible for watching out for.

Here are the teams: 

Boll/Arts: Cobblah, Star, Manyuru, Scott, Sanborn, Giles, Youk See, Fitz, Miklusak, Bradley

Library/Science: Fay, Ewing, Cribb, Sharon, Duane

Schoolhouse: Duval, Stiga, Rude, Morrison, Rude, Wade, Romero, Cousins, Libby

Thompson: W Smith, B Smith, Writer, Waldeck, Wei, Byrd, FitzGerald, Bates

Ward: Salvatore, Morales, Menkin, Heinze, Ward




We will play again in 2022!
