在伊利诺伊州卡本代尔的混合潮湿气候区建造了一座房屋，采用了目前最好的施工方法和常用材料。良好的被动式太阳能特性是通过正确定位房屋，使其有许多朝南的窗户，并有适当的悬挑，从而提供23%的供暖所需能量而获得的。房子还包括15厘米（6英寸）厚的绝缘墙，绝缘混凝土模板，基础围墙，绝缘轮辋托架，地源热泵，能源明星窗口，洗衣机，冰箱，紧凑型荧光灯泡（CFL）。分别对供暖、空调、热水、灯具和电器的用电数据进行计量。将实际房屋使用的能源与按照国际能源规范理事会2004年住宅能源规范建造的同尺寸房屋进行了比较。实际房屋使用的电量比code house少7809千瓦时（50%），每年节省成本826美元。 该房屋每年的现场用电量为19.8 kWh/m2。实际房屋的节能改造成本为7990美元。这栋房子非常经济划算，使用了商用材料，并雇佣了一名现场总承包商，该承包商在维护房屋设计的高能效标准、协调工作以及允许房主执行手动任务方面具有丰富的经验。这种方法的结果是完工楼面面积的价格为1062美元/平方米（99美元/平方英尺），明显低于该地区的同类房屋。单位:双引文:ASHRAE交易，第115卷，第。2009年1月1日，芝加哥

A house was constructed in Carbondale, IL, in the mixed humid climate region, using the best current construction methods with commonly available materials. Good passive solar characteristics were obtained by properly orientating the house to have many south-facing windows with proper overhangs which provided 23% of the energy needed for heating. The house also included 15 cm (6 in) thick insulated walls, insulated concrete forms for foundation walls, insulated rim joist, a ground-source heat pump, Energy-Star windows, clothes washer, refrigerator, and compact fluorescent bulbs (CFLs).Electrical usage data was metered separately for heating, air conditioning, hot water, lights and appliances. The energy used by the actual house was compared to the same sized house built to the International Energy Code Council 2004 Residential Energy Code. The actual house used 7809 kWh (50%) less than the code house for an annual cost savings of $826. The annual on-site electricity used by the house was 19.8 kWh/m2. Cost of the energy-efficient improvements in the actual house was $7,990. The house was very cost-effective by using commercially available materials and employing an on-site general contractor knowledgeable in maintaining the high energy-efficiency standards designed into the house, coordinating the work, and allowing the homeowners to perform manual tasks. This method resulted in a price of $1,062/m2($99/ft2) of finished floor area, noticeably less than a comparable house in the region.Units: Dual
