北卡罗来纳州琼斯县高度的公立学校有60多年的延期维护，迫切需要更换，许多公立学校都有过时的HVAC系统和其他基础设施不足。尽管有很大的需求，但学区的资金极为有限，可以实现这一目标。
解决问题的方法是琼斯县新的K-12学校项目。这项耗资4770万美元的项目通过创新的公私合作伙伴关系，提供了一个现代的，引人注目的设施，将该地区以前的小学，中学和高中结合到一个庞大的校园中，全部在一个屋顶下。
Designed and built as an energy-positive facility with nearly 2,150 rooftop solar panels, the building should generate roughly 75% more electricity than it consumes, estimates project owner and developer Firstfloor Energy Positive. Other features utilized to reduce energy consumption include geothermal wells, a building automation system, LED lighting throughout and daylight harvesting systems.
The result of this energy efficiency, Firstfloor asserts, is that over a 40-year span, Jones County’s costs for the new school—which it estimates at just $13.6 million—will be less than the operating savings from closing old schools. By comparison, Firstfloor estimates that a traditional project delivery would have resulted in a 40-year total cost to ownership of nearly $101.4 million.
Moreover, the team received $36.3 million from the sale of tax credits and grants, resulting in a total borrowed amount of $11.4 million. The resulting low cost enabled the school to be built without a tax increase.
Robbie Ferris说，该项目仍在制造中近十年，他负责Firstfloor Energy积极，并担任SFL+A Architects，Project Architects的首席执行官/总裁。
When Ferris first approached Jones County, roughly 10 years ago, the district was focused on simply building a new high school.
“In reality, they needed a new high school, elementary school and middle school, but they thought they’d never be able to afford that,” Ferris says. After the school board initially rebuffed the firm’s proposals for a combined K-12 school, the developer’s cost estimates began to take hold.
弗里斯说：“当我们开始运行数字时，学校董事会和县很快就加入了船。”“如果我们成功，我们认为他们可以通过关闭现有建筑物的节省而完全为新建筑物付费。”
The key was eliminating the schools’ power bills, which don’t exist as a result of the energy-positive replacement facility, thus saving the school district an estimated $18 million in energy costs over the building’s lifespan.
The energy-positive status comes from high-performance design features that collectively enable the facility to produce more energy than it consumes. In addition to the rooftop solar panels, contractor Metcon Construction and team installed geothermal wells to supply heating and air conditioning. A building automation system regulates air temperature and humidity levels as well as the school’s lighting controls and dynamic air-cleaning system.
建筑师SFL+A还利用了落地窗，其高性能玻璃专门允许日光和自然热量流入，同时将阳光直射熄灭，并在整个学校中使用了LED照明和日光收获系统。此外，位于建筑物入口处的能量仪表板显示了实时的能量数据，使学生能够参加开发人员主导的“能量”计划，该计划着重于资源保护的重要性。
还值得注意的是该项目的安全方法，该方法帮助该团队实现了大约249,600个工人小时，而OSHA可记录的事件或损失的时间事故。协助这项工作的是建筑团队与州劳工部的合作，以建立该项目为北卡罗来纳州建筑明星职位。该指定要求贸易伙伴的承诺，要求项目团队展示就业安全程序，这些工作人员的安全程序提高了最低要求。
The project—the construction and design team’s 11th energy-positive school to date—was completed in August 2019, on schedule and within budget.
