Why is life-cycle cost analysis (LCCA)—an evaluation method which assesses total cost of facility ownership— especially useful for comparingproject material alternatives? LCCA is only applicable where different materials have a similar energy benefit. LCCA takes into account all costs of acquiring, owning, and disposing of a building or building system. LCCA is an evaluation method for material durability only, not total cost of facility ownership. LCCA measures the ability of different materials to capture passive solar gain. OK Question Title * 2. Where can metal components be found on today’s buildings? Metal can be found across the entire modern enclosure, from roof to walls. Metal panels are approved for use on commercial roofs only. Metal panels are used for exterior sheathing only. Metal panels are recommended for walls only. OK Question Title * 3. What initial advantages can metal provide during construction? Installation is much quicker with metal than with other heavier and bulkier wall materials, resulting in significant labor and schedulingsavings. Metal roofs and walls can be erected even in inclement weather conditions, allowing construction to proceed regardless of the season and enabling contractors to move forward with interior work. The cost of risk insurance for metal buildings during construction is half that of other building materials because there is less risk of fire damage. Insurance may also be less after completion. All of the above OK Question Title * 4. How can the durability of metal walls and roofs support an extended building life cycle? Metal does not support building performance long term. Metal roofs and walls are extremely durable, and that durability means a longer product service life that requires minimal maintenance. Metal optimizes energy performance but is not durable. Metal is only considered a durable product when left unfinished. OK Question Title * 5. Why would metal be considered a sustainable material? Since metal is extremely durable with a long service life, this lowers demand for raw materials to produce replacement systems. The high recycled content and recyclability of metals like steel, aluminum, copper, and zinc allow for metal construction products to be routinely included on listings for “green” or sustainable buildingmaterials. Metal is not considered a sustainable material. Both A and B OK Question Title * 6. How does metal contribute to indoor environmental quality? Metal components with an applied finish are shop painted, limiting any volatile organic compounds (VOCs) to the controlled environment of the factory. Metal roofs and walls are inert, with no off-gassing and no VOCs. Metal is recyclable but offers no benefits at the interior of the structure. Metal and on-site painted drywall offer roughly the same indoor environmental quality. Metal does not contribute to indoor environmental quality. OK Question Title * 7. Cool roofs and walls are an emerging trend for commercial buildings. How do metal roofs and walls perform? Metal roofs offer an initial performance savings, but their reflectance quickly depreciates. Metal walls offer good insulation but cannot help buildings with solar reflectance. Cool metal roofing can achieve reflectance of more than 70 percent. The benefits of selecting metal for cool roofs and walls are as durable as the material itself: metal roofing maintains 95 percent of its solar reflectance over its service life. While metal roofs offer minimal reflectance, they can sustain this reflectance value over time. OK Question Title * 8. Why is it important to anticipate extreme weather events when planning and designing a building? To maximize its durability and life, a building must be equipped to shield its occupants from weather, fire, water, high winds, severe storms, and, where applicable, hurricanes and tornadoes. Weather events dictate how designers lay out a floor plan but not what materials may be needed. Weather events should not be a factor when planning structures. Since only wind and rain occur nationwide, these are the only weather events which should be considered. OK Question Title * 9. What natural attributes of metal help buildings survive during fire, water, high winds, severed storms, hurricanes, and tornadoes? Metal resists corrosion and mold only. Metal brings multiple benefits to the table when thinking about how best to preserve a building in the face of natural disasters. Metal panels can offer completely noncombustible surfaces, superior strength, ductility, and the ability to avoid corrosion and mold. Metal offers superior strength but no other benefits. Metal creates a noncombustible surface but offers no other durability benefits. OK Question Title * 10. What daily benefits can the low combustibility of metal offer to a building and its owners? Metal offers indoor environmental quality benefits but no other daily benefits. Low combustibility means better daylighting opportunities. Not only do metal roofs and walls protect during wildfire events on a daily basis, but they can also lower insurance premiums because of their fire resistance. Additionally, insurance premiums can be lowered because metal does not mold, corrode, or suffer from pest infiltration and damage. Metal does not offer benefits related to fire or combustibility.
