Homebuyers have higher expectations now than they did just a few years ago, and builders are responding with more houses that meet green building standards,a new study from Dodge Data & Analytics说。

More than half of the builders surveyed expect more than 60% of the houses they build will be green by 2020, with 36% of remodelers expecting to meet the same standards in their projects by then.

尽管四分之三的建筑商说，达到绿色标准的价格至少比传统建筑高5％，但他们中的大多数人认为，消费者愿意为使用较少能源，更耐用的房屋支付更多费用，并且具有更好的室内空气质量。

Exactly what constitutes a “green” home? As defined by the study, green building refers “specifically to homebuilding, home remodeling/renovating and land development that incorporates environmentally sensitive site planning, resource efficiency, energy and water efficiency, improved indoor environmental quality, and homeowner education, or projects the would comply with the ICC 700 National Green Building Standard or other credible rating systems.”

In other words, there’s still a lot of room for interpretation.

调查结果基于对全国房屋建筑商协会成员数据库中代表的建筑商和改建者的在线调查。总共包括249个响应，来自177名单户建筑商和开发商，55个单户重塑者和17家多户企业。

Banking on baby boomers

报告称，与年轻的购房者相比，“成熟”的购房者，55岁及以上的购房者，更关注住房的能源效率，室内环境质量和耐用性。但是千禧一代最终可能会赶上。

“The baby boomer generation is large and relatively affluent, which supports a stronger

green market currently, but there are also indications that demand may grow among millennials,” the report says.

For for now, the baby boomers are in the driver’s seat. For example, 81% of buyers over the age of 36 consider energy efficiency an influential factor, compared with 70% of buyers between the ages of 18 and 35. Sixty-seven percent of those 55 or older think that a healthier indoor living environment is important, compared with 55% of those aged 36-54 and only 49% of those in the 18-to-35 age bracket. Durability? Seventy-two percent of those 55 and up think its important; 47% of the 18-to-35 year olds would agree.

老年购房者的相对财富可以帮助解释为什么建筑商在未来几年中计划更多的绿色项目，尽管他们中的越来越多，绿色建筑的成本更高。2011年，道奇的一份报告发现，有58％的建筑商对一项调查的回应认为，绿色建筑的成本至少比传统建筑高5％。在2014年的一项调查中增长到60％，在最近的报告中增长到77％。

But the disparity in income between different age groups was only part of it. The study also found that older buyers had more experience with houses, and the more they knew about high-performance features the more likely they were to consider those features when making buying decisions.

Builders and remodelers said that 83% of home buyers would be willing to spend more for a healthier home, and the number of buyers willing to spend 5% to 10% more for a green home rose from 26% in 2011 to 33% this year. Still, costs remain a concern.

作者说：“行业必须解决成本问题，以了解绿色市场的全部潜力，尤其是当消费者期望新家是绿色的，因此可能不愿意付款该表现水平的溢价。”

更依赖可再生能源

All types of renewable energy have grown more common. In the two-year period between 2013 and 2015, the percentage of projects with photovoltaics (PV) jumped from 12% to 19%, but the real growth appears still to be in the future. Houses equipped with PV will grow to 48% of the market by 2018, builders and remodelers said, while solar hot water heating would increase to 41%, and ground-source heating equipment would rise to 52% of their projects.

接受调查的建筑商中有20％以上表示，他们已经建造了零净或净零的现成房屋，而报告90％或更多项目的建筑商中有58％是Green进行的净零或净零件。建造。

对可再生能源的兴趣似乎是由实用性驱动的：虽然有81％的55岁及以上的买家受到能源效率的影响，但该年龄段的人中只有8％的人给碳足迹减少了很多。相比之下，建筑商说，18-35岁年龄段的人中有12％认为碳足迹有影响力。
