寒江吹雪

项目名称：库马尔住宅
所 在 地：美国
这是由Zeitgeist
Design设计的美国库马尔住宅。一个中世纪的低矮平房贝尔蒙特位于加利福尼亚洲旧金山以南。最近进行了一次巨大的改造，新房子较从前的房子更加节能环保。整个设计由Zeitgeist
Design承担。房子增加了更多的娱乐空间，并尽量做到沙滩视野的最大化。库马尔住宅采用低锌板，整个建筑构成了一个紧密的绝缘体，高性能的窗户也为室内提供了良好的采光条件。
原来的房子建于19世纪50年代，只需要一些改造就可以为新用户使用。改造包括扩大娱乐空间，创建一个类似于复式结构的居住空间，同时为此地区创造更好的视野。在占地面积278.71平方米的建筑中，建有四居室和三个卫生间。并重新修改了前庭和后院的景观设计。滑动玻璃门将室内面积扩展到了院子中，并利用了室外温和的气候。
Zeitgeist利用被动的房子设计标准改造了这个家，整座房子有一个高水平的隔热和气密性。来自德国制造商Zola的热质量和高性能的窗户，绝缘的喷雾泡沫，和热回收通风，有助于整体家庭的紧密结构。此外房子里有一个高水平的日光穿透，可以在温和的月里享受自然通风。这种房子的设计不需要空调系统和也不用强加给业主一个低电费概念。

A mid-century ranch house Belmont， California -- just south of San
Francisco -- recently underwent a significant renovation leaving it far more
energy efficient than before. Designed by Zeitgeist Design， the home was
expanded to add more entertainment space and maximize on the views of the bay.
Clad in low-maintenance zinc panels， the Kumar Residence features a tight and
heavily insulated envelope with high performance windows that provide a high
level of daylighting inside.
The original home was built in the 1950s， but
was in need of some updating to make it work better for the new owners. It was
expanded to include more entertaining space with a loft-like living space and
improved views of the area. The 3，000-square-foot house has 4 bedrooms and 3 ½
baths and revamped front and backyard landscape. Sliding glass walls expand the
interior out into the yard to take advantage of the moderate
climate.
Zeitgeist was utilized Passive House design standards in the remodel
of this home and while the home is not certified， it does feature a high level
of insulation and air tightness. Spray foam insulation， high thermal mass and
high performance window units from German manufacturer Zola and heat recovery
ventilation， contribute to the home’s overall tight envelope. In addition， the
home features a high level of daylight penetration and enjoys natural
ventilation during more temperate months. There is no need for an air
conditioning system and the owners were sold on the concept of lower electric
bills with the help of a passive house-inspired design.
