We are very pleased to post the first two chapters of the new HDLC
Guidelines for your review and comment. I think (and hope) that
everyone will be very pleased with the results. It is critical that
we get everyone's comments on these two chapters by close of business
on Monday the 21st. The ten day comment period has been extended to
twelve days in honor of Christmas (and that we aren't in the office
over the weekend.)

Thanks for distributing these materials, Elliott. My comments on the Roofing document:
1) I don't see any reference to light roof colors, cool roofs, or Energy Star roofs.
I strongly recommend that the HDLC take a leadership role for New Orleans by mandating light colored roofs and encouraging Energy Star roofs when at all possible and appropriate. In high building and street density areas like many of our historic districts, in particular the French Quarter, the "heat island effect" of dark colored roofs, paved streets and sidewalks, and relatively little vegetation leads to temperatures that average 5 degrees hotter on summer afternoons than rural areas. Roof surface temperatures can have a temperature variation of as much as 100 degrees hotter from dark colored roofs to an Energy Star roof. Given our loss of more than 50% of our protective tree shading canopy citywide after Hurricane Katrina, it is more critical than ever that we recognize our extreme summer sun/temperature challenges and work to mitigate their impacts.
In addition to the negative livability impacts of the extreme heat island effect for everyone living, working and visiting our historic neighborhoods, dark colored roofs have numerous other negative impacts. Home and business owners of buildings with dark colored roofs pay higher utility bills than those with light colored roofs, as the heat transfer of solar energy through dark roofs translates into hotter attics, and therefore air conditioners that must run longer and more frequently to keep buildings comfortable. In addition, dark colored roofs have been shown to not last as long as light colored roofs, requiring more frequent replacement and less durability in extreme weather events. This is due to the higher daily heating of dark roofs, which leads to faster breakdown of roofing materials. From both a financial and from a safety/property protection standpoint, light colored roofs are the far superior choice.
Given our already extremely warm summer temperatures, our major loss of shading canopy, and the global trend towards increasingly warmer temperatures, the HDLC has an incredible opportunity to become a role model for historic district protectors nationwide by acknowledging the heat island effect, and New Orleans particular need to take advantage of all available tools to lower our daily temperatures. I can help the commission procure numerous supporting documents to support the above, and hope that this issue can be addressed.
Here is the EPA link regarding Energy Star roofs: http://www.energystar.gov/index.cfm?c=roof_prods.pr_roof_products
Here is the Florida Solar Energy Center's study showing the superiority of light colored roofs: http://www.fsec.ucf.edu/en/publications/html/FSEC-CR-904-96/
2) Green roofs should be allowed. Green roofs provide incredible benefits to neighborhoods, including reducing the heat island effect, providing excellent insulation and thereby lowering utility costs, and absorbing rain and stormwater, thus reducing street flooding. I recommend that green roofs be expressly allowed if not visible from the street.
3) Solar panels. I know this is a relatively new area, and am thrilled to see the HDLC clearly recognizing the value of solar panels in historic districts. However, I believe that the setback and visibility requirements are overly restrictive, and will have the effect of making the adoption of renewable energy impossible for many building owners desirous of utilizing this technology to lower their utility bills and carbon footprint.
Solar technology is advancing rapidly, and there are now numerous producers of thin film panels that lie flat on roofs, and come in colors which match roofing colors, and so are virtually unnoticable from the street. There are solar panels designed to mimic asphalt shingles, as well as ones that mimic tile shingles. I encourage further evaluation of available solar panels and an express allowance of Building Integrated Photovoltaic panels in visible areas where steps are taken to reduce their noticability. Here are links to a few of the latest solar panel designs that clearly would be in keeping with an historic district:

All,
Beth's recommendations should be strongly considered given the evolving nature of solar panel tachnology, alternative roofing materials and overall sustainability initiatives.

Elliot, There were no attachments with the guidelines for review. I
am sure they are fine but I can not comment on them since I did not
receive them. Thanks and Happy Holidays, Dorian
