Abstract

National Grid USA Service Company's (National Grid's) retail affiliates (Massachusetts Electric, Narragansett Electric, Granite State Electric, and Nantucket Electric) provide technical and financial assistance to their commercial and industrial customers for equipment and building energy efficiency improvements. Improvements can be either custom-engineered or selected from a list of prescribed measures. This impact evaluation study is Part II of two parts, and reviews two Custom HVAC projects completed in 2003.

The HVAC improvement projects included the installation of a variable frequency drive (VFD) on a chiller and transforming a single loop chilled water system into a primary/secondary loop system with VFDs on the secondary loop pumps.
