With energy efficiency and green design a priority for the new Museum Center on the grounds of Mark Twain s restored Hartford home, Robert A. M. Stern Architects turned to Hope s Windows for the structure s door and window systems. The results were astounding. Despite demanding environmental requirements, the building achieved energy usage 30% below mandated standards. What s more, when completed in 2004, the Center became the first museum to attain LEED certification from the U.S. Green Building Council. Energy efficiency was achieved without sacrificing aesthetic quality. Large expanses of glass, only possible when using steel systems, help create a light-filled interior that is elegant, graceful and meshes perfectly with the building s design and context.

U-Value ratings generally fall between 0.20 and 1.20. The lower the U-Value, the better a product is at keeping heat in. U-Value is particularly important in maintaining valuable energy. Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat from the sun. SHGC is expressed as a number between 0 and 1. The lower the SHGC, the better a product is at blocking unwanted heat gain. Blocking solar heat gain is particularly important during the summer cooling season. Visible Transmittance (VT) measures how much light comes through a product. VT is expressed as a number between 0 and 1. The higher the VT, the higher the potential for daylighting.

CONDENSATION AND STEEL WINDOWS: The Real Story Windows do not cause condensation. Condensation occurs first on windows because glass surfaces have the lowest temperature of any of the surfaces in a home. When the warm moist interior air comes into contact with the cooler glass surfaces, the moisture condenses. Therefore, there is no window material which will eliminate condensation. Windows are the visible evidence of excessive interior humidity. Indoor humidity must be controlled before condensation causes hidden problems elsewhere such as peeling paint, rotting wood, insulation deterioration, etc. The only solution is to control the sources of moisture and increase ventilation. With the advancements available today in HVAC systems and high performance glass, condensation can be controlled. There are maximum safe levels of humidity for buildings. If these humidity levels are maintained, excessive condensation can be avoided. The following are general recommendations: If outside temperature is zero or below not more than 20% humidity If outside temperature is zero to 20 degrees above not more than 30% humidity If outside temperature is over 20 degrees not more than 40% humidity It is unlikely that a building will ever become free of condensation, but by ensuring it is maintained in good condition and by making relatively minor lifestyle changes, condensation can be controlled.

ENVIRONMENTAL IMPACT of Hot-Rolled Steel Through decades of research, development and testing, Hope s Windows, Inc. has worked to perfect the handcrafted artistry of hot-rolled steel windows and doors. As our world changes, many new and unique building codes, policies and guidelines are established to help preserve our planet and natural resources. This is our story. Conserve natural resources Today, steel is the most recycled material in the United States. Each year, the steel industry saves enough energy through recycling to power 18 million homes one-fifth of the nation's households. We are proud of the fact that our steel windows and doors are made with hot-rolled sections that are 100% recycled steel. Improve air/water performance Fusion-welded corners and face-welded muntin intersections, providing seamless construction, set the standard for our impervious products. Hope's triple weatherstripping applied to integral grooves significantly reduces air infiltration and water penetration. Environmentally-friendly coatings An integral part of our 15-stage pretreatment process is an electro-deposited (E-coat) epoxy prime paint application. Hope s steel windows and doors E-coat process is lead-free, contains zero hazardous air pollutants (HAPs), and has ultra-low volatile organic content (VOC). Following the e-coat application, all steel surfaces receive a two-component polyurethane finish paint. This high performance finishing process results in a product with unlimited color options and extremely low maintenance requirements. Sustainability Strength and durability of hot-rolled steel consistently outperform wood, aluminum and vinyl products. The life cycle and unique characteristics of Hope's custom products provide unparalleled value. Hope's custom-made steel windows and doors offer impeccable quality, unrivaled artistry and superior strength that complement any architectural theme. Unlike windows made from aluminum or wood, the depth and visual mass of a steel window are extremely narrow. Large glass lites and narrow sightlines result in better energy efficiency and unmatched aesthetics.
