Green Technologies and LEED Certification

Homes and buildings impose a significant impact on our natural environment, economy, health, and productivity. According to the U.S. Department of Energy, buildings use 39% of the total energy and 74% of the electricity produced each year in the United States. By using "green" technologies such as Power*e™ Glass, we can reduce operating costs, enhance building values, improve air, thermal, and acoustic environments and enhance occupants' comfort and health. For these purposes, the U.S. Green Building Council has developed the LEED (Leadership in Energy and Environmental Design) green building rating system to provide guidance to improve energy savings, water efficiency, indoor environmental quality and other matters affecting building design, construction, operations and maintenance. LEED is the nationally accepted benchmark for the design, construction and operation of sustainable green buildings.

Power*e™ Glass and LEED Certification

As a “green” technology, Power*e™ Glass can contribute to LEED ratings and certification in many ways - in addition to improving building insulation and heating with less energy.

Tests demonstrate that the Power*e™ Glass uses up to 40% less power than natural gas forced air systems to provide more even and comfortable heat and eliminates or reduces the costs and need for other heating systems. These savings should increase when Power*e™ Glass is compared to other electric heating systems.

By stopping building heat loss through the heated glass, Power*e™ Glass substantially increases the insulating R-value of windows beyond other window technologies and contributes to the superior indoor environmental quality to maintain acceptable comfort conditions throughout the year. As a result, natural daylighting and the consequent vision of the building occupants provided by windows can be improved because windows can be located and sized without sacrificing the high performance building envelope.

As a radiant heating system, Power*e™ Glass improves the radiant comfort of a building over that offered by natural gas forced air and other conventional convection heating systems. Also, Power*e™ Glass does not use water like hot water VAV systems or radiant systems and reduces a building’s water and piping costs and requirements.

• Power*e™ Glass incorporates real time temperature sensors that provide immediate feed-back to building climate control systems and facilitates building energy comfort and climate controls optimization.

• Power*e™ Glass is a quick-response heating system that can help reduce a building’s annual energy costs by operating on an on-demand basis. Combining this with the highly distributed nature of the system, Power*e™ Glass means we can begin to efficiently use heat on an on-demand zoned basis, the way we use light. With innovative control systems, Power*e™ Glass can be activated by motion sensors, radiant heat sensors (human body heat), and other on-demand indications, potentially saving vast amounts of energy currently being wasted on unoccupied spaces.

Maintenance and building operating costs are minimized because Power*e™ Glass windows have no air handling equipment or moving parts to break and no water lines buried in the foundation, walls or ceilings to leak.

• Power*e™ Glass is a totally silent heating system. This makes it ideal for classrooms, conference rooms and other spaces where ambient noise from heating systems is an unwanted nuisance (or worse).

• Power*e™ Glass does not move air around. This means it doesn’t require blowers and won’t create drafts. But it also means that in environments such as schools, hospitals and science labs, air-borne pathogens are not carried from space to space by the heating system.

There is no condensation on Power*e™ Glass even when heated at low interior temperatures, and this may contribute to limiting mold and microflora growth. By improving daylighting and its natural sanitizing capability, Power*e™ Glass can also help limit mold and microflora growth.
