Natural cooling

In the days before mechanical air-conditioning, this was how people beat the heat, and it can work surprisingly well. Natural cooling is an element of passive solar design, and involves blocking heat transfer through shading, insulation, thoughtful landscaping, and window placement; removing heat with fans, vents, and cross-ventilation; and reducing the use of heat-generating lights and appliances. In dry climates, evaporative cooling systems-which distribute moist air to cool a room-are a good natural alternative to traditional air conditioners. Even taking a nap in the hottest part of the day can be a part of a natural cooling approach. Do you really need another excuse? Also called passive cooling.

Word of the Day
   Heating, ventilation, and air-conditioning (HVAC)

Looking for the perfect climate? You could hightail it to San Diego, or you could get it in your own home, anytime, with HVAC. It's what makes your inside air cozy in winter, cool in summer and fresh all the time. More technically, these are the mechanisms that regulate temperature and airflow in a building. HVAC consumes the greatest portion of energy in most buildings, and how well it does its job has a direct impact on a home's energy efficiency and indoor air quality. To pronounce it like a pro, just sound out each letter, H-V-A-C.
