Information on several greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. More than 80 percent of recycled steel was utilized to construct the Hearst Tower in New York. The architects of the proposed Urban Cactus apartment building in Rotterdam, Netherlands plan to add solar panels in the building design. The Bank of America Tower in New York reuses rainwater and has water-saving plumbing fixtures in its bathrooms.

Information on the building design of greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. The triangular window frames of the Hearst Tower located in New York allows natural light inside the building compared to the normal design of windows. It is added that architects are considering various ways to make older skyscrapers environment-friendly like attaching outdoor structures that may allow the construction of wind turbines.

Information on the ventilation system of greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Some greenscrapers have built-in ventilation structures that allow fresh air to flow naturally inside the buildings without the use of electricity. Thermal chimneys is another kind of ventilation system that allow warm air to flow out of a building through a chimney.

Information on the use of wind power by greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Some greenscrapers use wind turbines to generate electricity from the wind. The wind turbines of the Bahrain World Trade Center in Bahrain can produce one-tenth of the energy being needed by the building to run.

Information on the use of solar energy by greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Common skyscrapers use large amounts of electric power to run its computers, refrigerators and other machines. Solar panels are installed in greenscrapers for it can capture solar energy to produce electrical power that the buildings can use. Although these panels will not work during the night or cloudy days when the sun is not visible, they can be connected to rechargeable batteries to store energy.

Information on the rooftop gardens of some greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Some greenscrapers have rooftops planted with grasses, flowers and trees that are not only for decorative purposes for it provide insulation benefits. These gardens also have the capability to reduce heat island effect or the absorption of heat by building structures and surfaces.

Information on the heating and cooling system of greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Builders of greenscrapers place insulation within the walls and roofs of the building to keep heated air inside during the winter season and prevent cooled air from escaping during the summer season. Computerized climate-control systems are also being utilized in some greenscrapers to monitor temperature and automatically adjust hotness or coolness inside the building.

Information on the light sources of greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. It is revealed that lighting constitutes 30 percent of the energy resources being used in office and school buildings. Compact fluorescent lightbulbs (CFLs) used in greenscrapers may be expensive compared to incandescent lightbulbs but they require less electricity and last longer, making them a more cost-effective option in lighting.

Information on how greenscrapers or environment-friendly skyscrapers conserve water from the book "Building Greenscrapers" is presented. The importance of freshwater is emphasized, mentioning the various uses for it to people which includes cooking and growing food. Greenscrapers have the capacity to collect rainwater that may be used in its toilets and cooling system.

Information on building greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. Compared to skyscrapers that use natural resources like steel that are in limited supply, recycled materials are utilized to create new steel for building greenscrapers. It is also noted that recycled plastics may also be used to create carpeting and ceiling tiles for modern buildings.

Information on greenscrapers or environment-friendly skyscrapers from the book "Building Greenscrapers" is presented. To build skyscrapers, great amounts of natural resources are needed and it require lots of energy resources to maintain its lighting and ventilation systems. Greenscrapers are considered more energy efficient for they have the capacity to provide better indoor air and create less pollution compared to traditional skyscrapers.

A chapter from the book "Building Greenscrapers" is presented. It is emphasized that everyone can practice ecologically friendly habits even if they do not live in a greenscraper or environment-friendly skyscrapers. The use of compact fluorescent lightbulbs (CFLs) is said to be more energy-efficient compared to incandescent lightbulbs. Turning off the lights is said to be one of the simple things anyone can do to conserve electricity.
