All commercial new construction (CNC) projects will continue to be required to submit a lighting power calculation using Efficiency Vermont's lighting power density (LPD) tool. However, until now, only a "space-by-space" method could be used to make this calculation.
Starting in July, for interior lighting, either the "building area" or the "space-by-space" method can be used. We are in the process of updating the tool. The new version will be posted on the Lighting Power Density Tool web page during the first week of July.
