#An Efficient Design and a Carefully Detailed Envelope Add up to Big Energy Savings
工匠平房以舒适，实用和用当地天然材料精心制作而闻名。康涅狄格州南格拉斯顿伯里（South Glastonbury）的这座LEED黄金之家结合了所有这些品质等。为了实现房主建立一个愉快且经济的退休场所的目标，CK建筑师为一个有吸引力，高效和适应能力的计划写下了。精心详细的建筑信封，离散安装的光伏阵列和地面源热泵使房屋负担得起。
Let nature work for you
Beneficial natural conditions paired with good design choices helped maximize the project’s sustainable features. An L-shaped house plan and a central screened porch let cooling breezes pass right through the house. An existing clearing made it easy to install the horizontal heat-pump loop and then cover it with a meadow of wildflowers. The landscaped portions of the site contain large beds of noninvasive, drought-tolerant plants, minimizing the need for irrigation and yard work.
专为轻松生活而设计
Farmed white cedar shingles, fiber-cement siding, and cellular PVC trim ensure that the home’s exterior is low-maintenance and durable. CK Architects left the core living area open with plenty of south-facing windows, creating a bright, functional, and efficient space. Less frequently used, the guest rooms are deliberately isolated from the rest of the house, allowing John and Karen to reduce their heating demands when visitors aren’t around.
早期行动回报
The build team’s commitment to environmental responsibility made joining the LEED for Homes pilot program an easy decision. Doing this early in the process guided smart choices on everything from initial site preparations to interior finishes. Architect Russell Campaigne estimated that the green building methods added about a 5% premium over a comparable home built to code. With utility bills for the first year averaging less than $100 a month (pretty good considering Connecticut has some of the highest electric rates in the country), it seems that the investment is paying off.
Lessons Learned
Russell Campaigne referred to Energy Star guidelines when planning the insulation and air sealing for the house. Although the blown and batt fiberglass tested and ultimately performed very well, sprayed-in-place foam would have definitely been easier to install. After describing the difficulty in detailing the fiberglass correctly, Russell commented, "the contractor would have been happy to pay the extra cost of the foam."
他还发现，筛选的Breezeway的表现比预期的要好。树荫和房屋的漏斗形状使其在夏季变得凉爽得多，并且有很多太阳能收益有助于在春季初期打破寒冷。
Builder鲍勃Dykins的绿色建筑there needs to be more focus on methods that foster durability. On this project, planning siding laps to fall at the tops of windows, using strips of tarpaper as additional sill flashing over the siding below, and thoroughly air sealing below wall plates and around openings were a few simple steps that will make a long-term difference in the home's performance.

If the HERS score is
如果她的分数为33 ...这不是意味着它将使用比“参考主页”的可比构建的能量少67％？
Where does the 75% lower utility bill come from?
Another reason that it may be
另一个原因是，要求降低75％的公用事业账单可能是误导的。...当您平均基本费用时，效率更高的房屋每单位罚款额外支付单位罚款。
换句话说，即使您使用的能源减少了67％。.您的账单不会少67％...您仍然必须添加基本费用。

澄清节能主张
John, you have a good point. The case study stated that there was a 75% energy savings over a comparable home. The reason that there might have been a difference between this number and the HERS score is that the HERS rating is a theoretical number whereas the 75% number was based on more than one year of actual energy bills. The flaw is that I did not present clear data for what represents the average home. I am editing the text to more clearly represent the data that we do have for this house. Thanks for your input.
$ 250/sf
$ 250/平方英尺的近3000SF（$ 741,000）真的可持续吗？CT中的普通人可以负担住在那里吗？
框架技术
您是否选择将螺柱16“ O.C置于24”的原因是有原因的吗？另外，使用较厚的基础是否在成本和能源使用方面更有效？

没有什么绿色建筑产品itemized. You just introduced a whole bunch of chemistry for the family to breathe and absorb through dermal exposure. I applaud the use of the ERV Venmar to help control the indoor humidity levels, but for the climate zone wouldn't an HRV be more appropriate? A merv 8 filter is a why bother solution to doing nothing at all. May be good for capturing large particulate like dog hair. A suggestion would be to incorporate a merv 13 at minimum and add activated carbon filtration to adsorb some of the emitting chemistry from the air.
