美国圣地亚哥第一座被动式房屋,太阳能发电与风力发电相搭配


美国圣地亚哥第一座被动式房屋近日建成,房子完全采用可循环绿色材料,能源来自于太阳能电池板和长达17英尺(约5.7米)的风力涡轮。承包商Alliance Green Builder在这栋房子里安装了脱离电网系统,全部家用消耗电力完全自给。这项应用获得了具有国际声誉的建筑认证系统LEED颁发的“白金”级(最高级别)认证。高效保温循环系统、一流的隔热和智能化设备的配合使用,使这栋房屋成为了绿色建筑的典范。


房子位于加利福尼亚州的Ramona的山顶上,这里四季分明,是较为典型的半沙漠干旱气候。冬季寒冷,有时低于零度,夏季气温会达到32度甚至更高。在这样的气候条件下,建造房屋的要求就是隔热性好、保温效果好。另外房间得需要配备热循环通风设备,以此来保证室内优化的空气和适宜的温度。


房子整体复杂而完善的能量系统能够百分百保证房子水电自给自足。目前,房子能够自己生产足够的可循环清洁能源,并通过一个高效电池设备给房间供能,并且留有足够的储备能源。更重要的是,这栋房子位于一个无与伦比的风能集中的地区,丰富的风力资源在整个美国境内都数一数二。设计师利用这一优势,在山上安装了一个2.3千万的风力涡轮,涡轮机带来的能源能保证日常的能源消耗,维持时间每天最短12小时。


房间内部各种节能家用设备应有尽有,节能性强的电磁炉、热泵干燥机,高效的LED节能灯,电力消耗监控设备随时提供准确的数据。

San Diego’s first off-grid Passive House has its very own wind turbine


San Diego's first certified Passive House, which contains an astounding mixture of sustainable features, gets all its energy from a solar array and a 17-foot wind turbine. San Diego contractor Alliance Green Builder created a system that would take the building off-grid and earn Casa Aquila a LEED Platinum certification. Combined with thermal efficient heat recovery, top-notch insulation and plenty of smart features, the home is a truly impressive example of green living.


The project is located on a hilltop in Ramona, California, where temperatures are sometimes below freezing in the winter and often in excess of 100-degrees in the summer. This desert-like climate called for a solution that would include high insulation and an air-tight envelope. A heat recovery ventilation system provides optimal indoor air quality and maintains thermal efficiency.


The most impressive aspect of the home is the sophisticated energy system, which is expected to eventually take the home off-grid. Currently, the house generates renewable energy and runs off a battery system, utilizing the grid only for back-up energy. Its prominent location is one of the best sites in San Diego County for harvesting wind-generated energy. A 2.3 kW, 17-foot high wind turbine was installed on a hill just above the home and is expected to generate energy almost every day in a year for a minimum of 12 hours a day. Large dual-axis trackers outfitted with 24 solar panels are expected to produce the bulk of the energy produced on site-around 44,000 kWh per year.


Inside the house, various energy-efficient appliances such as an induction cooktop and a heat pump dryer ensure a lower than average energy consumption. High-efficacy LED lighting is used throughout, with several control and monitoring systems providing data for energy use and generation, as well as water resource levels and water consumption.
