Emerging technologies represent the newest segment of products with the potential to reduce energy consumption. Periodic reviews of these technologies enables concentration on developing the strongest contenders. This analysis, the fourth of its kind, highlights 15 of the most promising heating, ventilating and air conditioning (HVAC) emerging technologies. Full adoption of these technologies would reduce projected US energy consumption by 0.5% - 1% per year. One important finding of this study is that the "well" of emerging technologies and practices has not been drawn down; it continues to yield many promising measures with high energy savings potential.
The technologies covered include:
