SUSTAINABLE ARCHITECTURE is a general term that describes environmentally conscious design techniques in the field of architecture. Sustainable architecture is framed by the larger discussion of sustainability and the pressing economic and political issues of our world. In the broad context, sustainable architecture seeks to minimize the negative environmental impact of buildings by enhancing efficiency and moderation in the use of materials, energy, and development space. Most simply, the idea of sustainability, or ecological design, is to ensure that our actions and decisions today do not inhibit the opportunities of future generations. This term can be used to describe an energy and ecologically conscious approach to the design of the built environment.

GREEN ARCHITECTURE Green Architecture (also known as green construction or sustainable building) is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. This practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Although new technologies are constantly being developed to complement current practices in creating greener structures, the common objective is that green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:
• Efficiently using energy, water, and other resources • Protecting occupant health and improving employee productivity
• Reducing waste, pollution and environmental degradation A similar concept is natural building, which is usually on a smaller scale and tends to focus on the use of natural materials that are available locally. Other related topics include sustainable design and green architecture. Green building does not specifically address the issue of the retrofiting existing homes.

HEATING, VENTILATION AND COOLING SYSTEM EFFICIENCY The most important and cost effective element of an efficient heating, ventilating, and air conditioning (HVAC) system is a well insulated building. A more efficient building requires less heat generating or dissipating power, but may require more ventilation capacity to expel polluted indoor air. Significant amounts of energy are flushed out of buildings in the water, air and compost streams. Off the shelf, on-site energy recycling technologies can effectively recapture energy from waste hot water and stale air and transfer that energy into incoming fresh cold water or fresh air. Recapture of energy for uses other than gardening from compost leaving buildings requires centralized anaerobic digesters. Passive solar building design allows buildings to harness the energy of the sun efficiently without the use of any active solar mechanisms such as photovoltaic cells or solar hot water panels. Low energy designs also requires the use of solar shading, by means of awnings, blinds or shutters, to relieve the solar heat gain in summer and to reduce the need for artificial cooling. In addition, low energy buildings typically have a very low surface area to volume ratio to minimize heat loss. Windows are placed to maximize the input of heat-creating light while minimizing the loss of heat through glass, a poor
insulator. In the northern hemisphere this usually involves installing a large number of south-facing windows to collect direct sun and severely restricting the number of north-facing windows. Certain window types, such as double or triple glazed insulated windows with gas filled spaces and low emissivity (low-E) coatings, provide much better insulation than single-pane glass windows. Preventing excess solar gain by means of solar shading devices in the summer months is important to reduce cooling needs. Deciduous trees are often planted in front of windows to block excessive sun in summer with their leaves but allow light through in winter when their leaves fall off. Louvers or light shelves are installed to allow the sunlight in during the winter (when the sun is lower in the sky) and keep it out in the summer (when the sun is high in the sky). Coniferous or evergreen plants are often planted to the north of buildings to shield against cold north winds.
Sustainability Building Energy efficiency over the entire life cycle of a building is the single most important goal of sustainable architecture. Architects use many different techniques to reduce the energy needs of buildings and increase their ability to capture or generate their own energy.

GOALS OF GREEN The concept of sustainable development can be traced to the energy (especially fossil oil) crisis and the environment pollution concern in the 1970s. The green building movement in the U.S. originated from the need and desire for more energy efficient and environmentally friendly construction practices. There are a number of motives to building green, including environmental, economic, and social benefits. However, modern sustainability initiatives call for an integrated and synergistic design to both new construction and in the retrofitting of an existing structure. Also known as sustainable design, this approach integrates the building life-cycle with each green practice employed with a design-purpose to create a synergy amongst the practices used. Green building brings together a vast array of practices and techniques to reduce and ultimately eliminate the impacts of new buildings on the environment and human health. It often emphasizes taking advantage of renewable resources, e.g., using sunlight through passive solar, active solar, and photovoltaic techniques and using plants and trees through green roofs, rain gardens, and for reduction of rainwater run-off. Many other techniques, such as using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water, are used as well.
While the practices, or technologies, employed in green building are constantly evolving and may differ from region to region, there are fundamental principles that persist from which the method is derived: Siting and Structure Design Efficiency, Energy Efficiency, Water Efficiency, Materials Efficiency, Indoor Environmental Quality Enhancement, Operations and Maintenance Optimization, and Waste and Toxics Reduction. The essence of green building is an optimization of one or more of these principles. Also, with the proper synergistic design, individual green building technologies may work together to produce a greater cumulative effect. On the aesthetic side of green architecture or sustainable design is the philosophy of designing a building that is in harmony with the natural features and resources surrounding the site. There are several key steps in designing sustainable buildings: specify ‘green’ building materials from local sources, reduce loads, optimize systems, and generate on-site renewable energy.
Our Process We manufactures the best insulating glass in the world. ECO GLASS is the most eco-friendly glass on the market helping you achieve your GREEN Building objectives and higher LEED certifications. About 25 years ago, some very inventive folks at MIT created a revolution in insulating glass by adding a unique coated film between the two panes of insulating glass. That film, Heat Mirror, allows the glass to deliver greater control of R-values, UV protection and other comfort benefits not available from any other insulating glass.

ECO GLASS is the greenest glass on the market today with dramatically superior performance characteristics. Windows can play a critical role in reducing energy consumption since 40% of that energy is lost through those windows. The wasted energy results in over 250 million tons of emissions per year. A typical commercial or residential window will have an R-Value of R-2 to R-4. Windows with ECO GLASS can typically deliver an R-5 to R-14 and higher. A significant reduction in energy costs provides a fast payback. A smaller HVAC HVAC (Heating, Ventilating, and Air Conditioning) system is typically needed which further reduces capital costs and speeds up ROI (Retern of Invesment). ECO GLASS allows architects the design freedom to use more glass in more creative ways and deliver the highest LEED certifications possible. No other insulating glass delivers the performance of ECO GLASS.

THE BENEFITS COMFORT Heat Mirror glazing offers improved air quality, fresh air, increased daylighting, reduced noise and controlled temperatures. These features make a marked difference in our general well being and performance. INSULATION Heat Mirror glazing has DOUBLE the insulation compared to the best LowE / Argon glazing glass in the marketplace Typically 25-35% of a buildings energy is lost through it windows. We know that thecost of oil and electricity will continue to climb. Heat Mirror’s insulation reduces the amount of energy lost and significantly reduces the buildings heating and cooling bills, month over month for the Life Cycle of the building. Heat Mirror’s insulating properties allows engineers to downsize the entire HVAC assembly and system. Perimeter heating may be reduced or eliminated because of the increased insulation. SOLAR HEAT CONTROL Heat Mirror’s solar heat properties can be customized to meet a buildings needs. From Passive Solar to the best Solar Heat management capabilities in glazing. This equates to decreased operating costs by reducing the amount of energy required to run our boilers or chillers and lower capital costs by downsizing the capacity of these units. ELIMINATES CONDENSATION ON GLASS Heat Mirror makes a significant reduction or total elimination of harmful interior condensation. Since Heat Mirror provides outstanding insulation, a much higher level of humidity can be tolerated within the building before condensation forms. Heat Mirror resists wintertime condensation at exterior temperatures up to 45 ºC colder than conventional insulating glass. Reducing the risk of mould growth is a particularly important benefit for Health environments. DAY LIGHTING Heat Mirror provides the Optimum solution for natural daylighting. Its solar capabilities allow short-wave energy to be transmitted through the glass (natural light), but reflects long wave infrared radiation (solar heat). Daylighting that is comfortable and enjoyable. Tinted glazing is no longer a requisite. The perpetual use of blinds and shading devices is eliminated. In a Heat Mirror glazed building the occupants enjoy the benefits that natural lighting is meant to provide.
SOUND CONTROL In noisy environments, Heat Mirror’s unique construction insulates against unwanted sound transmission better than ordinary double-pane windows. As building technology becomes more sophisticated, improved performance requirements are being placed on building components. The need for acoustical glazing solutions is increasing due to environmental noise caused by aircraft, highway traffic, rail transportation, and the congestion of buildings around areas of high noise levels. Consumer / Owner demands are requiring building components such as insulating glass meet specified Sound Transmission Loss (STL) levels. STL is a standardized measure of the noise reduction in decibels for specific frequency ranges. Determining sound transmission loss—The American Society for Testing and Materials (ASTM) has developed a Sound Transmission Class, or STC rating, in which a single number rating is used for describing the sound isolation performance of a material. The higher the STC number the better the system is at isolating airborne noise. An STC rating of 45 means that the element reduces the sound passing through it by 45 dB. The higher the STC values, the greater the noise reduction. Using different thickness’ of glass gives greater noise reduction. The resonances for each layer fall at different frequencies thereby reducing noise. Staggering the thickness of the air/gas space has the same effect by altering the resonances. Heat Mirror® film suspended between 2 lites will increase ratings by 1 to 2 points depending on the insulating glass make-up. ULTRAVIOLET FADING REDUCTION Heat Mirror with XUV transmits less than one half of 1% of UV radiation -50 times less than competitive Low-E window products and more than 100 times less than ordinary double-pane glass—while maintaining a clear, colorless appearance. For those institutions where ultra-violet light is detrimental, Heat Mirror is a perfect solution. The optimum in natural light with limited UV penetration.
