The Skyscraper Museum is devoted to the study of high-rise building, past, present, and future. The Museum explores tall buildings as objects of design, products of technology, sites of construction, investments in real estate, and places of work and residence. This site will look better in a browser that supports web standards, but it is accessible to any browser or Internet device.

R-Value - A unit of thermal resistance. A material’s
R-value is a measure of the effectiveness of the material in stopping the
flow of heat through it. The higher a material’s R-value, the greater
its insulating properties and the slower the heat flow through it.
Rainwater Harvesting - The collection, storage, and reuse
of rainwater.
Recycling - A series of processes that include collection, separation, and
processing by which products and raw materials are recovered and reused
in lieu of disposal as solid or liquid wastes. Commonly recycled items include
cans and bottles, paper and industrial solvents. Recycling can also apply
to construction materials, and even to buildings themselves.
Regeneration - Renewal of sites or habitats that have become unfit for human,
animal, or plant habitation, bringing them back into productive use. The
term most commonly refers to urban and industrial land.
Renewable Energy Sources - Energy sources that replenish themselves naturally
within a short period of time. Sources of renewable energy include solar
energy, hydroelectric power, geothermal energy, wind power, ocean thermal
energy, wave power, wind power and fuel wood.
Return On Investment (ROI) - An economic indicator that is
used to evaluate the effectiveness of an investment. It is calculated as
the ratio of the amount gained or lost relative to the amount invested.
Simple ROI analyses do not take the time value of money into account. On
the other hand, dynamic ROI analyses recognize that the value of money does
change over time.
