本月初,美国的第一座建筑物允许将雨水用于饮用用途,也成为了一座生活建筑,这是国际生活未来研究所授予的最高水平的超绿色建筑认证。The 10,520-sq-ft Brock Environmental Center in Virginia Beach, Va., is one of 44 buildings to have achieved partial or full certification under ILFI’s decade-old Living Building Challenge, which is considered the most rigorous sustainable design, construction and performance standard.

Over the course of a year, Brock produced 1.83 times more energy than it consumed. The building’s performance “far surpassed all of our goals,” said Mary Tod Winchester, vice president of administration and operations for Brock’s owner, the Chesapeake Bay Foundation (CBF), at ILFI’s “Living Future 2016” conference. The 10th annual gathering, held May 11-13 in Seattle, had 931 attendees.

生活建筑candidates achieve certification only if their teams meet strict performance goals around energy and water use. Buildings registered for the Living Building Challenge do not receive certification until at least a year after the buildings are fully occupied.

因此,对于设计师而言,一个生活建筑项目有三个阶段:设计,建筑和后建筑物。梅拉说:“一年来的每一天,我都会在上午12:04收到一封电子邮件,详细介绍能源和用水。”

为了与CBF的环境教育任务保持一致,Brock团队正在分享有关该项目的信息,包括许多经验教训。

喝雨水

布罗克(Brock)必须成为公共水上工厂,以获得监管部门的批准,以治疗雨水以供饮用物(Enr 3/14p。49)。新利18备用“这是一个有趣的挑战,”布罗克经理克里斯·戈里(Chris Gorri)说。除了受过训练的建筑工程的日常系统监控外,顾问每月都会有顾问。

In its first year of operation, the building had an energy-use intensity of 14.12, which represents an 80% savings over an average building with an EUI of 69.82, said Mella. The Brock team had predicted an EUI of 16.

Brock harvests energy from 46.5 kW of installed solar photovoltaics and two on-site 10-kW wind turbines. The 70-ft-tall turbines have a 38-year payback period, mostly because poor soils required 100-ft-deep piles.

梅拉说:“基金会包括涡轮机是勇敢的”,因为社区害怕杀死鸟类,与他们作战。

与平均非住宅建筑物相比,布罗克(Brock)容纳25人的工作人员,使用了96%的能量来照明;电拔球负载的能量减少86%;加热和冷却的能量减少67%;通风能量减少51%;梅拉说,热水能量减少了40%。

The building used half the lighting energy predicted. A long, narrow floor plate and no adjacent buildings helped maximize daylighting.

插头负载通常是建筑物中使用的功率的25%。梅拉说,它们很难预测,因为乘员行为有些未知。布罗克(Brock)的团队准确地预测了插头负载,但Mella建议设计团队随着时间的推移注意插件蠕变。

Brock has energy-efficient copiers and laptop monitors. A kill switch automatically shuts down computers and other equipment at night, said Gorri.

CBF’s headquarters, the 15-year-old Philip Merrill Environmental Center in Annapolis, was the first LEED Platinum building. “We raised the bar with the Merrill center, and we knew we could raise the bar again,” said Winchester. “The Living Building Challenge provided that road map.”
