MR-6: Energy Efficiency

To LionelL: excellent suggestions. We would like to move this credit to something more results-based in Version 2.0. Like what you are talking about. Would like to have a standard "baseline" to which comparisons are made. That way you can reduce energy by any means possible (fewer fixtures, more efficient fixtures or both or something else). Look for this improvement in Version 2.0.

This credit provides points for efficient lighting. However, why not provide points for reduced lighting also. There are studies that show fewer luminaires can be used on lighter colored pavements. Perhaps there could be points awarded for demonstrating that 20% or 30% fewer luminaires were used or 20% - 30% less power was used from a certain baseline, which is the goal of the credit.1,2

2. Jobanputra, W., Influence of Pavement Reflectance on Lighting of Parking Lots. PCA 2458. Portland Cement Association, Skokie, IL, 2005.

Suggest changing credit requirements to:

Goal

Reduce lifetime energy consumption of lighting systems for roadways.

Requirements (meet one of the following requirements):

1. Install lighting systems with luminaires that meet or exceed the 2009 Energy Star standard for roadway lighting and are compliant with all safety requirements applicable to the roadway project. The 2009 Energy Star Standard is available at: http://www.drintl.com/htmlemail/ESOutdoorDraft2_01Jul09.pdf

2. Demonstrate 30% energy savings over a baseline design for a typical dark-colored pavement by using light colored pavement and reducing light bulb wattage per lamppost or by reducing the number of lampposts.

These technologies actually would fit under the custom credit for Alternative Energy instead of Energy Efficiency. Thanks for the reference.

Score the use of lampposts self powered by solar and/or wind energy. See http://www.aminternacional.org/PDF/ProjetoEnergiaEolicaSolar.pdf
