  • Atlanta renovation achieves highest LEED score in Northern Hemisphere

    Atlanta renovation achieves highest LEED score in Northern Hemisphere
    1315 Peachtree in Midtown Atlanta has secured 95 LEED points, the most of any "New Construction" in the Northern Hemisphere.

    A renovated building in Midtown Atlanta has been awarded 95 out of a possible 110 LEED points for its environmental design-the highest score for any new construction in the Northern Hemisphere.

    Though classified as a "New Construction" in the Leadership in Energy and Environmental Design system, 1315 Peachtree Street, Atlanta is actually a 1980s construction that has undergone extensive renovation. But what does LEED certification entail? And is this the greenest building in the Northern Hemisphere?

    According to the architect, Perkins+Will, who are both the designers and occupants of the renovated building, a variety of technologies were employed to help achieve Platinum certification. A trigeneration system (providing electricity, heating and cooling) is foremost among them, employing gas microturbines on the roof generating both electricity and heat. Some of that heat drives an absorption chiller providing the building's cooling. Daylight harvesting and LED lighting are among the measures which have reduced the building's energy consumption by a claimed 58 percent from baseline figures. Rainwater harvesting has cut the consumption of supplied water by 78 percent. Both figures are well above that required to achieve maximum points in their respective criteria.

    LEED essentially provides a collection of yardsticks next to which some of a building's green credentials can be measured. Eighty points are sufficient to win Platinum status in version 3 of the system, which has been in use since 2009, and is the version with which 1315 Peachtree Steet was scored. Platinum is the highest of four levels of certification, followed by Gold, Silver and, yes, Certified.

    One hundred of the available points are spread over five categories with the largely self-explanatory titles Energy and Atmosphere (worth 35 points), Water Efficiency (10), Materials and Resources (14), Sustainable Sites (26), and Indoor Environmental Quality (15). An additional six bonus points are available for "innovation in design", and the final four are for "Regional Priority"—or measures that address localized environmental issues. One of the "innovation in design" points is available for the involvement of a LEED-accredited professional in the design—a point which has no direct bearing on the greenness (or otherwise) of the building at hand. A full breakdown of the points system, and an explanation of the criteria, is available on the US Green Building Council's website.

    To achieve LEED certification, building owners must cough up registration and certification fees to the US Green Building Council, and provide documentary evidence of compliance with the scheme, which is verified by the Council. The process is purely voluntary, meaning that buildings with extremely environmentally-sound design may go uncertified. However, LEED-certification is increasingly being encouraged and even mandated at state level, and within federal agencies.

    According to the US Green Building Council's Certified Project Directory, 245 projects have been assessed under the same system and category (LEED-NC v2009), and of those 25 have been awarded a Platinum certificate. So, of the nearly-10,000 projects LEED-certified in the US alone, 1315 Peachtree Street is only directly comparable to 245.

    LEED 2009 places a greater emphasis than ever before on energy reduction, but is criticized in some quarters for not going far enough. A relatively whopping 19 points—the single biggest allocation—are available for optimized energy performance. In new buildings the full points haul requires energy savings of 48 percent in comparison to a theoretical baseline. By contrast the Architecture 2030 program calls for a minimum reduction of 60 percent, measured against regional averages rather than theoretical data. If buildings are now close to maxing out on the LEED scoring system, perhaps a general raising of expectations is merited.

    Of greater concern is the suggestion that LEED-certified buildings do not always save the amounts of energy that is claimed. Savings are established by the building designer who measures the building design against a minimum requirement (ASHRAE Standard 90.1 - Energy Standard for Buildings Except Low-Rise Residential Buildings). What that minimum standard specifically entails will vary from building to building, and is quantified by the buildings designer through computer modeling.

    Doubt would be reduced by verification of certification based on real-world use once the building is occupied. An assessment based on design data would still be required (where final planning permission is dependent on LEED certification, for instance), but the status would be provisional. The technology is already available to do this relatively painlessly through the remote reading of meter data via the 'Net. Were LEED to adopt such an approach, there's no reason that LEED certification could not become a live status requiring maintenance over time rather than being the one-off badge of honor that it is. Financial penalties for design assessments that fall well short of the reality may help the problem of optimistic LEED assessments—if such a problem exists.

    Though scorecards under older certification systems are available from the project directory, none for the 245 projects in 1315 Peachtree Street's category are. But without the documentary evidence used to establish the LEED rating, and real-world performance data to compare it to, the information that could be gleaned would be extremely limited in any case.

    A LEED score of 95 points suggests that a building should be extremely environmentally friendly, but the only conclusion that can be drawn with absolute certainty is that its design is adept at passing LEED tests. In 1315 Peachtree Street's case, it, of all the buildings in the Northern Hemisphere, is the LEEDiest of 245.

    The US Green Building Council has not responded to our request to see 1315 Peachtree Street's LEED assessment, and the architect declined to respond to our technical queries about the specifics of the renovation.

  • Save money by irrigating with harvested rainwater

    By Charla Anthonycharla.anthony@theeagle.com

     

     

    While rainwater harvesting is an ancient technique, it fell out of favor as communities grew more urban. Recent weather trends of extended drought and high summer temperatures have renewed interest in this conservation practice.

    Rainwater harvesting simply captures, diverts and stores rainwater. Runoff is the rainwater that flows off a surface such as a roof. This water can be captured and stored. There are numerous benefits to harvesting rainwater.

    Why harvest rainwater

    In many communities, 30 to 50 percent of the total water is used for landscape irrigation, and the easiest way to use stored rainwater is in landscapes. You can save money by collecting and storing rainwater and using it to irrigate your trees, shrubs and lawn.

    Harvesting rainwater for use in the home landscape:

    * Saves money by reducing your water bills

    * Reduces demand on the municipal water supply

    * Makes efficient use of a valuable resource

    * Reduces flooding, erosion and the contamination of surface water with sediments, fertilizers and pesticides in rainfall run-off

    Rainwater is good for plants because it is free of salts and other minerals that harm root growth. It can be harvested and used immediately to water plants or stored for later use. Capture systems can be used both in large-scale landscapes, such as schools, municipal facilities, or parks, as well as in residential landscapes.

    How rainwater harvesting works

    Runoff, the rainwater that flows off a surface, is harvested. A simple water harvesting system usually consists of a catchment, a distribution system and a landscape holding area.

    Catchment area

    The most common catchment area is a roof. Paved areas and even the soil surface "catch" rain. The amount of water harvested depends on the catchment size, surface texture, slope and rainfall received. One inch of rain falling on 1 square foot of surface yields approximately .6 (six tenths) gallons of water.

    Transporting rainwater

    If you have gutters and downspouts on your house or garage, you have a fantastic system for harvesting rainwater. Transportation systems channel water from catchments to landscape holding areas. Sloped sidewalks, hillsides, street and curb cutouts, ditches and swales also transport water.

    Storage

    Collected rainwater may be stored in above ground containers including plastic or steel drums, barrels, tanks, cisterns, and stock tanks. Underground containers may be utilized for storage, but cost more to install, utilize and maintain. A holding area can be a raingarden, a concave or planted area bound by a border or earthen berm.

    Using Collected Rainwater

    A distribution system -- garden hoses, solid or perforated pipes, and low volume or drip irrigation lines -- delivers collected water to plants from storage containers. Small pumps, gates, diverters and filters may be required to transport water to plants.

    DIY System Design

    Steps involved in designing a water harvesting system include site analysis, calculating the supply, system design, and construction. While these steps may appear complicated, the process is fairly simple. To learn more visit this online website: rainwaterharvesting.tamu.edu

    The demand for water, a limited natural resource, can be reduced through rainwater harvesting, and everyone benefits.

  • Georgia Gets More Time To Work On Water Conservation; But Water Wars Are Not Over

    By Guest Columnist STEVE O’DAY, section head of environmental and sustainability practice group for Smith Gambrell & Russell

    If you are sitting back thinking the most recent decision in the Water Wars means Atlanta’s worries are over, turn off that faucet and think again.

    Last Tuesday, a three-judge panel for the U.S. Eleventh Circuit Court of Appeals overturned a lower court’s 2009 decision that it was illegal for the U.S. Army Corps of Engineers (“Corps”) to draw water from Lake Lanier to benefit the metro Atlanta area and otherwise relieved Georgia from the “draconian” obligation to work out water issues with Alabama and Florida by July 2012 or be cut off from the reservoir.

    The decision also provides Georgia with a strong bargaining chip in negotiations with Alabama and Florida: the panel specifically recognized that the legislation authorizing Buford Dam anticipated that the metro area would need greater withdrawals from the lake over time, a hotly-contested fact among the three states.

    Winning a battle does not, however, mean the war is over.

    Alabama Gov. Robert Bentley has already announced he will ask the entire Eleventh Circuit court to reconsider the panel’s decision. If that fails, the decision can—and likely will—be appealed to the U.S. Supreme Court.

    Meanwhile, Alabama has asked U.S District Judge Karen Bowdre in Alabama to lift the stay of its lawsuit with Georgia over waters in another basin that provides drinking water to metro Atlanta–the ACT (Alabama, Coosa, Tallapoosa) Basin.

    The 11th Circuit decision also places the burden squarely on the Corps to decide, within one year, how to allocate the water in Lake Lanier. The water allocation plan will still impose restrictions on the amount of water that can be withdrawn and allocated to municipal water use.

    Moreover, it’s important to remember that it was the failure of the Corps to respond to Georgia’s request that it increase metro Atlanta’s share of water in Lake Lanier in 2000 to help meet the increasing demands of the metro Atlanta area, that re-started the Tri-State Water Wars.

    If the past is any indication of the future, it is very likely that the Corps’ water allocation plan will not provide Georgia with unfettered access to Lake Lanier, without a demonstration from the state, and metro area, that it is taking usage of this resource seriously.

    For these reasons, and others, Georgia should continue down the path of fully implementing water conservation practices and investment in infrastructure upgrades, while continuing to negotiate for a fair allocation of water usage to all the competing interests in the river basins.

    It is clear that, on the heels of record-breaking droughts and amidst record-breaking population growth, the Southeast is facing serious concerns regarding water.

    In the metro Atlanta area alone, approximately 652 million gallons of water are used every day and it is predicted that in Georgia’s 16-county Metropolitan North Georgia Water Planning District, the population will increase to nearly eight million by 2030.

    Without adequate planning and more efficient use of the region’s water resources, the demands of population growth could lead to exhaustion of available water supplies as soon as 2017.

    Accordingly, while last Tuesday’s decision is certainly a plus in Georgia’s column, rather than shouting the “victory” from the rooftops, residents and representatives are well advised to recognize this decision for what it really is: extra time on the clock.

    It is time to take accountability for our water usage. We must do this by instituting additional conservation practices in addition to diligent implementation – not relaxation – of the clean water laws protecting our water resources that are critical not only to our economic, but also our personal, well-being.

    Smith Gambrell & Russell associate Jessica Lee Reece contributed to this column.
