I have no idea how much electricity that second refrigerator in the basement consumes, or how much I'd save by keeping the house 2 degrees cooler in the winter and 2 degrees warmer in the summer.

对于地下室里的家中第二台电冰箱耗电多少，冬天要是室内降2度、夏天室内升2度我又能节省多少钱，我则毫无概念。

New, special, thick glass will replace the glass currently in the windows. This insulated glass will make the inside of the building cooler in summer and warmer in winter.

新型，特制的加厚玻璃将取代目前窗户上的玻璃，这种隔热玻璃将使大楼里面冬暖夏凉。

It's a little warmer in summer, and a little cooler in winter, but every day is a beach day for somebody.

冬暖夏凉，对于某些人来说每天都是晒太阳的好日子。

The geothermal system heats and cools using piping that goes deep within the earth, where temperatures are warmer than outside air in the winter and cooler in the summer.
