架构师提供的文本描述。如果一所学校的设计和建造能够产生与它从电网中消耗的能源一样多的能量，那该怎么办？如果很少或根本不需要电力来使用空调、照明或电力，那该怎么办？暖气费、热水费、煮食费和地面灌溉费都有限制吗？

Text description provided by the architects. What if a school could be designed and built to produce as much energy (on site) as it consumes from the electric grid? What if there was little or no need for electricity for use of air-conditioning, lighting or power? Limited gas bill for heating, hot water, or cooking food and no water bill for ground irrigation?

这些都是欧文独立学区开始规划第八所中学时敢于问的问题。出现在德克萨斯州欧文市的152，000平方英尺的女伯德·约翰逊中学.最近建成的教育设施现在享有全国最大的净零公立学校、全国第一所净零公立学校和得克萨斯州第一所净零公立学校的声誉。

These were the questions the Irving Independent School District dared to ask when it began planning the district’s eighth middle school. What emerged was the 152,000-square-foot Lady Bird Johnson Middle School in Irving, Texas. The recently completed educational facility now holds the prestige of being the largest net zero public school in the country, the first net zero middle school in the country and the first net zero public school in Texas.

按照定义，作为一个净零建筑，女士伯德约翰逊MS产生的能量比它在12个月期间消耗的更多。采用了若干技术和战略来减少能源消耗，包括地热供暖、太阳能电池板技术、风力涡轮机、雨水收集技术和智能太阳能管理。

By definition as a net zero building, Lady Bird Johnson MS produces more energy than it consumes over a 12-month period. Several technologies and strategies were employed to reduce its consumption including geothermal heating, solar panel technology, wind turbines, rain water harvesting techniques and smart solar management.

Sangeetha Karthik，AIA，LEED AP BD C，Corgan Associates，项目首席建筑师Sangeetha Karthik说：“LadyBirdJohnson MS是美国第一所净零学校，并且正在追求LEED黄金认证。”“学校的一般信息是减少、再利用、循环利用和教育后代，使他们成为环境的管理者。我们有意识地作出选择，以支持建筑物的整体信息，同时保持经济和建筑使用的角度。“

“Lady Bird Johnson MS is the first net zero school is the country and is pursuing LEED gold certification,” said Sangeetha Karthik, AIA, LEED AP BD + C, Corgan Associates, project lead architect. “The general message of the school is to reduce, reuse, recycle and educate future generations to become stewards of the environment. We made conscious choices to support the overall message of the building while keeping the economics and use of the building in perspective.”

除了在学校的整体外部广泛使用法布雷尔墙板外，该设施最突出的特点之一是建筑两侧有一个巨大的天篷。被法布雷尔制造的金属包层覆盖着，天篷高耸在西侧的教室窗户上，环绕着大楼，遮住了朝南的图书馆窗户。这种结构阻止炎热的德克萨斯夏季阳光穿过教室和其他窗户，同时仍然允许自然照明。在冬天，当太阳在天空下时，光线直接穿过窗户，为建筑物提供了温暖和热量。林冠的宽度是通过分析学生在教室的时间和月份的太阳角度来确定的。

Aside from the extensive use of Fabral wall panels on the overall exterior of the school, one of the most prominent features of the facility is a large canopy that stands on two sides of the building. Covered in Fabral manufactured metal cladding, the canopy towers over the west side classroom windows and wraps around the building to shade the south facing library windows. This structure blocks the hot Texas summer sun from passing through classroom and other windows while still allowing natural lighting. In the winter, when the sun is lower in the sky, the rays pass directly through the windows, providing warmth and heat to the building. The width of the canopy was determined by analyzing the sun angles during the times and months when students are in their classrooms.

在建筑物本身，高效率的玻璃和增加的绝缘法布雷尔闪光灯和装饰，帮助建筑物保持与外部因素的紧密绝缘。所有产品都是在亮银中指定的，这是一种战略性的选择，因为它的浅色和反射特性有助于减少吸热，提高建筑的整体能源效率。

On the building itself, high-efficiency glazing and the increased insulation from Fabral flashing and trim help the building to stay tightly insulated from outside elements. All products were specified in Bright Silver, a finish strategically chosen for its light color and reflective properties which help reduce heat absorption, enhancing the building’s overall energy efficiency.

伯德·约翰逊夫人中学被设想为一所具有创新21世纪理想的邻里中学。由于使用了高效的材料和尖端的可再生能源技术，该建筑成为一个三维学习空间。来自全区的学生，以及伯德·约翰逊夫人考勤区的学生，将通过实际的亲身体验，学习环境管理、节能以及地热科学、雨水收集、太阳能电池板使用和风力涡轮机效率等方面的经验。因为这所学校为全区所有学生提供了独特的学习机会。校园的设计是每天接待60-70名来访的学生.该项目将于2011年底向美国绿色建筑委员会(USGBC)申请LEED黄金认证。

Lady Bird Johnson Middle School was envisioned as a neighborhood middle school organized with innovative 21st century ideals. Because of the use of efficient materials and cutting-edge renewable energy technology, the building becomes a three-dimensional learning space. Students from across the district, as well as within the Lady Bird Johnson MS attendance zone, will learn through practical, hands-on experiences about environmental stewardship, energy conservation and such topics as geothermal science, rainwater collection, solar panel usage, and wind turbine efficiency. Because the school presents unique learning opportunities for all students in the District, the campus has been designed to host 60-70 visiting students on a daily basis. The project will apply for LEED GOLD Certification with the United States Green Building Council (USGBC) at the end of 2011.
