Energy Efficient Windows for Mid- & High-rise Residential Buildings
Energy-efficient windows save heating and cooling energy and improve occupant comfort while allowing for downsized HVAC equipment. Residential-type ENERGY STAR windows are a good choice for saving energy in single family and many multifamily buildings. However, structural, safety and facade design considerations in mid- and high-rise buildings often call for commercial-type windows which are not part of the ENERGY STAR program. Whichever the case, the simple guidelines presented here can help you specify energy efficient options from among the different types of windows used in mid- and high-rise residential applications.

Window Energy Efficiency Solutions for Public and Affordable Housing
Energy-efficient windows lower energy bills, improve occupant comfort, and reduce condensation. Although initial cost is often a barrier in low-income housing, window energy efficiency measures may qualify for financing and incentive programs and may allow for smaller, less expensive HVAC equipment due to lower heating and cooling loads. Also note that in buildings with lead paint hazard, window replacement can be the single most effective way to eliminate lead dust. Where windows are in good condition and without lead paint, storm windows and shading devices are also feasible energy efficiency options.

Tools for Schools
As energy prices increase and school budgets tighten, school districts are looking for cost- effective ways to improve building energy efficiency and operation. With almost one quarter of Americans spending their day in the classroom, efficient window design is an important opportunity to not only save energy and money but also to enhance the learning environment. Windows affect heating and cooling needs, the potential for natural ventilation, and the availability and quality of daylight. Integrated de- sign that takes these factors into account can improve a school's energy performance as well as students' visual and thermal comfort.
