Rating the performance of a Passivhaus-certified home using the Home Energy Rating (HERS) Index or another rating system might seem like topping a sundae with a cherry: it’s okay to add the ornament, but it really doesn’t make the sundae any better.

但是，现实是，被动别墅机构美国在寻找帮助市场的方法，并通过其他组织审计和评估的经过认证的房屋似乎是该战略的一部分。它不仅仅是用樱桃装饰的日本人，也是加入洒水，坚果和切碎的椰子。

2月，Phius宣布与能源审计专家住宅能源服务网络（Reset）的协议将Hers索引评级分配给所有Passivhaus建筑物在周一Phius宣布，它将有助于根据所创建的能量性能评分（EPS）评级系统来帮助开发“里程贴纸”地球优势研究所是一家基于俄勒冈州波特兰的非营利绿色建筑组织。

性能比较

尽管她的指数measures the performance of a house relative to that of hypothetical home built to the specifications of the 2006 International Energy Conservation Code, the EPS system compares the audit home’s energy consumption and carbon emissions with those of a comparably sized home that has been audited in the same climate zone. Data from a blower-door test, combined with an analysis of the home’s insulation system and its fuel costs for heating, cooling, water heating, lights and appliances, is used to calculate the building’s total annual energy use in kilowatt-hours. So far, Earth Advantage Institute says, it has certified more than 11,000 homes, mostly in the Northwest.

很难想象经过认证的项目Passivhaus标准，其对施工行业最严格的密闭，绝缘和窗口性能的要求，在该地区的每一个可比家庭都会有很多麻烦，除了也许是其他Passivhaus建筑物。但这就是点。

“被动房屋认证提供的大规模节能在地球优势研究所执行董事肖恩佩里斯肖恩佩里斯在南北和全国其他地区引起了重大关注。“随着地球优势研究所的到达建设者和房主社区的能力，本协议与PHIU协议使双方能够为主流带来更高水平的住宅能源绩效。”
