What is the year of introduction in the US commercial market for each
of the following energy efficiency technologies?

Compact fluorescent light bulbs
Reflective glass for windows
Specular reflectors in fluorescent light fixtures
Electronic ballasts for fluoescent lighting
Centralized energy management and control systems for buildings
Variable air volume (VAV) systems for heating and cooling systems

For each, I need the year of introduction and the source(s) of the
information. If there is conflicting information, then provide all
dates found and the sources of those dates.

By "introduction" I mean that the product was available for purchase
in the United States for use in a commercial building such as an
office, store, school, or hospital.

Hi drbeet,

I was able to find these two:

Compact fluorescent light bulbs - 1980

"The most important innovation in home lighting during the past forty
years is, without a doubt, the compact fluorescent light. First
introduced in the United States in 1980, the compact fluorescent light
is a miniaturized version of the straight-tube fluorescent. Instead of
a 2-foot, 4-foot, or 8-foot fluorescent tube with separate ballast in
a light fixture, manufacturers have packaged both ballast and
fluorescent tube (lamp) into a unit slightly larger than a standard
light bulb."

Compact Fluorescent Lamp ? 1980 The compact fluorescent lamp
revolutionized the lighting industry.It is simply a folded fluorescent
tube,usually no larger than a standard incandescent light bulb.

======================================

Electronic ballasts for fluoescent lighting - 1977

ELECTRONIC BALLASTS - Program Description and History
"From 1977 to 1981, DOE supported the development, evaluation, and
market introduction of electronic ballasts into the U.S. marketplace.
The fluorescent lamp electronic ballast that emerged from this work in
1983 impelled industry to proceed with large-scale commercial
development and has become arguably the most successful initiative in
the entire DOE energy efficiency portfolio.

Over the years since the lighting program was introduced in 1977,
sponsored activities have covered a wide range of energy-saving
opportunities in lighting."

I hope this helps.
