This course explores the fundamental connection between light and health by examining how translucent structural sandwich panels deliver glare-free, diffuse daylight deeper and more evenly into spaces with maximum thermal efficiency. Learning Objectives: At the end of this program, participants will be able to: discuss the impact translucent fenestration systems can have on the daylighting, energy efficiency, aesthetics, safety, and privacy of a building. explain why daylight modeling is an effective tool in helping to determine the amount and type of daylight that is available to a project and how deeply that daylight will travel into a building. discuss how diffused lighting can positively impact the health and overall well-being of building occupants in a variety of commercial settings. examine how translucent structural sandwich panels are made and why, by their makeup, they can improve daylighting within an interior and the thermal performance of the envelope. ©2021 ∙ Table of Contents < Slide 7 of 101 > About the Instructor About the Sponsor Ask an Expert Contents Daylighting Is Sustainable Design Daylight Modeling The Power of Diffusion Translucent Fiberglass Reinforced Polymer (FRP) Structural Composite Panels Benefits of Translucent Structural Sandwich Panels Structural Skylight and Canopy System Applications Summary ©2021 ∙ Table of Contents < Slide 8 of 101 > About the Instructor About the Sponsor Ask an Expert Daylighting Is Sustainable Design ©2021 ∙ Table of Contents < Slide 9 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylighting? Daylighting is the art of placing apertures into buildings to control either direct or indirect sunlight that penetrates the space to provide interior lighting. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and productive environment for building occupants while reducing as much as one-third of total building energy costs. In architecture, daylighting has gone through a complete 360°. Originally, it was one of the most important aspects of building design, with buildings being planned around movements of the sun to capture the most lighting. This meant that houses in the Northern Hemisphere had fewer windows on the polar side wall than facing south. The opposite was true in the Southern Hemisphere. Then, with the advent of electrical lighting, daylighting became less important and purely aesthetic or utilitarian. Now, architects and designers are placing more and more emphasis back on daylighting and the benefits it brings. ©2021 ∙ Table of Contents < Slide 10 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylighting? In science, computers can now run daylight modeling exercises, generating lux levels, daylight autonomy reports, levels of radiance illuminance, and glare pattern analyses. This technology can find that “sweet spot” between lighting, climate, warmth, and health benefits. In art, daylighting is managed to maximize visual and thermal comfort and/or to reduce energy use from artificial lighting—it’s not just throwing uncontrolled sunlight into a space. Specific daylighting strategies can be used to highlight architectural features and to bring accents to different spaces. By allowing full-spectrum color rendering, daylighting provides an ideal space for showcasing artwork and artistic, scientific, historical, and technological materials. ©2021 ∙ Table of Contents < Slide 11 of 101 > About the Instructor About the Sponsor Ask an Expert Daylight Is Not Direct Sunlight People have been harvesting daylight for thousands of years. The ancient Egyptians covered windows and doorways with reed mats to shade the interior and keep out heat; since Roman times, glass has been used to allow light into a space while blocking out dust, dirt, and wind. While the principle and goal of harvesting daylight remains, technology has developed, and now, translucent panels, sun tubes, and smart glass are providing innovative solutions to reduce energy use and improve occupant comfort. ©2021 ∙ Table of Contents < Slide 12 of 101 > About the Instructor About the Sponsor Ask an Expert Daylight Is Not Direct Sunlight Sunlight provides natural lighting, but simply letting sunlight into a building does not necessarily create a well-lit interior. Letting sunlight penetrate an interior through a specific opening in a wall or ceiling means only a particular interior space will be lit and only by whatever lighting conditions the outside environment can provide. Oftentimes, a high visible light transmittance (VLT) can be problematic; VLT alone shouldn’t be used for a design strategy. This photo illustrates the effect of just letting sunlight/natural light in. The direct beam of illumination has created areas of high contrast between light and dark. A small area of the interior space is overlit, leaving the remaining area in deep shadow. These types of poor lighting conditions lead to hotspots and glare that tires the eyes and hinders visual acuity. Since sunlight’s intensity and color can vary from day to day and season to season, the light levels in this interior will vary greatly as well. ©2021 ∙ Table of Contents < Slide 13 of 101 > About the Instructor About the Sponsor Ask an Expert Why Daylighting? Glass has been used as the portal to the outdoors for centuries. But times are changing. In a world where we are becoming more aware of the environmental effects of structures and people’s changing needs, architects and other industry professionals are concerned that glass no longer adequately addresses these key building factors: daylighting energy efficiency bird strikes safety privacy maintenance ©2021 ∙ Table of Contents < Slide 14 of 101 > About the Instructor About the Sponsor Ask an Expert Daylighting Is Sustainable Design Maximizing daylighting is now considered to be fundamental to effective and sustainable design. In the same way that sunshine impacts how we see and feel, daylighting influences energy use, material selection, indoor air quality, and how people react to and behave in the interior environment. The problem, of course, is to reconcile this with increasingly stringent regulations about energy loss through the building envelope. Happily, several glazing and translucent system manufacturers now offer new designs and new technology to provide effective solutions. The challenges associated with improving and maintaining our physical well-being while being mindful of our environmental impact are forcing us to examine how we light our hospitals, schools, offices, gymnasiums, and other buildings where we are spending more time. ©2021 ∙ Table of Contents < Slide 15 of 101 > About the Instructor About the Sponsor Ask an Expert Efficient Daylighting: Energy Use Maximizing the use of natural light and minimizing the use of electricity needs to be a priority in any building project, whether new or retrofit. Thermal and solar heat gain performance is key when factoring in the high costs of energy for heating or cooling. Efficient daylighting design reduces the need for artificial/electric lighting and can drastically reduce heating, ventilation, and air conditioning (HVAC) costs by creating an efficient thermal envelope. Allowing for higher visible light transmittance is not the objective. In fact, allowing in too much natural light can lead to higher cooling costs. ©2021 ∙ Table of Contents < Slide 16 of 101 > About the Instructor About the Sponsor Ask an Expert Efficient Daylighting: Balancing Occupant Comfort and Energy Use Despite recent efficiency gains in lighting technology, the amount of electricity used by the US and around the world continues to increase. According to the US Energy Information Administration’s International Energy Outlook 2017, the world energy consumption is expected to increase 28% by 2040. With regulations becoming more stringent, builders, designers, and manufacturers are being pushed to find ways to be more energy efficient in their use of building materials, fenestration, lighting, and daylighting. How do you find a balance between human needs and energy saving? As we live longer and continue to work beyond the traditional retirement age, we are incrementally spending more time in buildings with artificial light. Factor in the increased levels of lighting needed to accommodate the eyesight aging process, and the result is a higher energy consumption. Energy efficiency codes vary by state in the US, but the majority have adopted at least some version of ASHRAE Standard 90.1 and the International Energy Conservation Code (IECC). This is forcing us to think differently in how we manufacture, design, and build lighting systems. ©2021 ∙ Table of Contents < Slide 17 of 101 > About the Instructor About the Sponsor Ask an Expert Effective Daylighting: Occupant Comfort and Health Light affects the human circadian system. We must constantly be aware that: maintaining the proper circadian stimulus is essential to supporting a healthy sleep–wake schedule, and Inadequate overexposure to improperly lit rooms lacking views to the world daylighting outside affects not only our eyesight but also our overall physical and mental well-being. Without the right amount of exposure to daylight and views to the outside, our: alertness and productivity drops, and memory and cognitive functions are negatively affected. Diffuse, full-spectrum daylighting ©2021 ∙ Table of Contents < Slide 18 of 101 > About the Instructor About the Sponsor Ask an Expert Effective Daylighting: Occupant Comfort and Health In its “Advanced Energy Design Guide for K–12 School Buildings,” the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) describes good daylighting as seeking “the right balance between enough daylight and too much sunlight, which can be a source of glare and excessive heat gain.” Introducing natural daylight without glare or excessive heat is a foundational part of creating a great learning space. Good daylighting in schools has proved to have a marked calming influence on pupil behavior and learning. Research shows that learning rates are higher in reading and math in classrooms with the most natural daylight. At the same time, daylighting has an enormous effect on the overall well-being of the students, including improved behavior and less absenteeism. ©2021 ∙ Table of Contents < Slide 19 of 101 > About the Instructor About the Sponsor Ask an Expert Effective Daylighting: Occupant Comfort and Health Natural daylight is essential for increased productivity in a work environment. A 2017 study conducted by Cornell University professor Alan Hedge found that optimizing visual comfort in an office environment with balanced daylighting and views significantly improves health and wellness among workers, leading to gains in productivity. Office workers reported having fewer headaches, less drowsiness, and reduced eyestrain. The study also found that there are adverse effects when offices rely solely on glass windows for their lighting needs since uncontrolled light leads to direct glare from sunlight and indirect glare from reflective surfaces, such as computer screens and worktops. Covering the windows with blinds can be inefficient and damaging because workers then must rely on artificial lighting sources, and they do not get the health benefits associated with exposure to natural daylight.

Daylight modeling brings science into the art of daylighting. It removes the design mystery and reveals the pattern of daylight on any building through 3D simulation software. Architects and designers use daylight simulation services to demonstrate the impact of their daylighting design options to achieve balanced, glare-free daylighting and to document contributions to sustainability objectives, including those of Net Zero, BREEAM®, LEED®, and the WELL Building Standard®. Factors taken into consideration include building orientation, location, local climate data, and interior finishes, all of which impact the amount of available daylight for a specific project. Daylight modeling software can help quantify daylight- transmitting products, determine optimal light transmission, help with positioning on a building to prevent glare issues, and provide interior lux levels. ©2021 ∙ Table of Contents < Slide 25 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylight Modeling?

Point-in-Time Radiance Simulation: A metric that looks at specific light levels at a set day and time using localized weather conditions to review lighting design and glare. Illuminance: The quantity of light emitted by a source that falls on a surface. Illuminance is measured in lux (lumens per m2) or footcandles (lumens per ft2). Results shown in lux (1 fc = 10.76 lux). ©2021 ∙ Table of Contents < Slide 27 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylight Modeling? Useful Daylight Illuminance (UDI): An annual illuminance metric that describes multiple categories of “usable” lux levels in a space, reporting a percentage of floor area that falls within a specified illuminance range for 50% of the time. Daylight illuminance levels 3,000 lux are generally not usable, as this is likely to produce visual and thermal discomfort. ©2021 ∙ Table of Contents < Slide 28 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylight Modeling? Spatial Daylight Autonomy (sDA): A measure of annual daylight sufficient for a given area, reporting a percentage of floor area that exceeds a specified illuminance level (e.g., 300 lux) for a defined analysis period (10 hours/day, 365 days/year). For LEED projects, scoring varies by building type; higher scores equal more credits. sDA 300/50% (300 lux for 50% of annual hours) 40% = 1 credit 55% = 2 credits 75% = 3 credits ©2021 ∙ Table of Contents < Slide 29 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylight Modeling? Annual Sunlight Exposure (ASE): A measurement to help limit excessive sunlight in a space. Defined as the percentage of a space in which direct sun exposure exceeds a predefined threshold (e.g., 1,000 lux) for some quantity of hours (e.g., 250 hours) in a year. Although not technically a glare metric (see DGP on next slide), ASE values can be used as a guide to identify potential sources of glare and solar heat gain. ASE is used in conjunction with sDA to determine LEED credits per the Illuminating Engineering Society’s Lighting Measurement 83 (LM-83), “Approved Method: IES Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE).” ASE is not an issue when using translucent materials. However, transparent materials are problematic due to direct sunlight. LEED projects must demonstrate ASE 1,000, 250 h (1,000 lux for 250 hours) for 10% of the space. If ASE is >10%, glare conditions must be addressed, or the project will receive a FAIL score for all LEED daylighting credits. ©2021 ∙ Table of Contents < Slide 30 of 101 > About the Instructor About the Sponsor Ask an Expert What Is Daylight Modeling?

This short video is a snapshot of the capabilities of daylight modeling and shows how daylight modeling can assist with optimizing design. Shown is a comparison between glass and a translucent sandwich panel. By eliminating uncontrolled sunlight and reducing the reliance on artificial light, architects and designers can introduce the dramatic benefits produced by diffuse natural daylight. It’s not about choosing the product with the highest levels of visible light transmittance but about making an impact with the ideal amount of usable light while minimizing glare.

Daylight modeling reports can be displayed through a false color grid and renderings. The reports can be looked at from a cost point of view and recommendations made depending on the results. After an initial analysis, a design team can look at individual rooms or at the overall situation and then modify the building model to reflect options that may improve the daylight design, such as changing glazing location or light transmittance. In the example shown, toplighting was added when the initial design featuring punched openings did not achieve the desired light levels. ©2021 ∙ Table of Contents < Slide 34 of 101 > About the Instructor About the Sponsor Ask an Expert Optimizing Design A daylighting analysis takes the unpredictability out of a site- specific daylighting design.

Glass is the oldest way of allowing natural light into a building. Its transparency offers unparalleled visual freedom with those inherent biophilic advantages of linking people to nature. Along with its benefits, glass brings several challenges to the fenestration industry. It is probably the heaviest material and can be costly, inflexible, and fragile. It can also provide relatively poor thermal properties, and it needs a secondary solution to control solar gain and glare. Polycarbonate sheeting offers a stronger, more durable, and lighter alternative to glass and helps block harmful UV rays, but it also has several disadvantages. It can be easily scratched and become discolored and brittle over time. In addition to poor impact resistance, it has very low levels of thermal efficiency and will melt and drip when exposed to flame. Acrylic is probably the least expensive glazing option. It can offer UV resistance, but it often offers the shortest life expectancy because it becomes brittle over time. ©2021 ∙ Table of Contents < Slide 40 of 101 > About the Instructor About the Sponsor Ask an Expert Glazing Materials Fiber reinforced polymer (FRP) panels offer distinct advantages over both glass and polycarbonate in terms of weight and thermal insulation (which can be the same as an insulated cavity wall). In addition, FRP panels offer the highest protection and resistance to wind-borne debris, impact, abrasion, and point loads. Sometimes, incorporating more than one product offers the best solution. For example, you can achieve the performance benefits of an FRP panel while incorporating vision glazing for a connection with the outdoors. ©2021 ∙ Table of Contents < Slide 41 of 101 > About the Instructor About the Sponsor Ask an Expert Additional Glazing Factors to Consider Selecting fenestration products for a project requires considering many performance factors of the glazing material and the components of a fenestration system. The National Fenestration Rating Council (NFRC) is an independent nonprofit organization that offers standardized testing and documentation of the total performance of fenestration products and systems. NFRC-certified products receive the NFRC label that is designed to help consumers and designers compare the energy performance of a product in several categories—all of which are important in a daylighting analysis. (Link accessed Apr. 2021.) U-factor measures how well a product can keep heat from escaping from the inside of a space. The lower the number, the better a product is at keeping heat in. The overall thermal performance of a product should take into consideration performance of the whole framing system. Insulated translucent FRP sandwich panels are capable of achieving a U-value from 0.5 to 0.29. Visible light transmittance (VLT) measures how much light enters a space through materials. VLT is reported by the NFRC on a scale of zero to one, e.g., 0.65, where the higher the number, the more light is let in. Manufacturers may report VLT as a percentage, e.g., 65%. VLT is only a measure of the amount of light, not the quality or usability of that light. VLT alone does not indicate daylighting success, it must be looked at for each specific application to understand how the product impacts daylighting goals. Solar heat gain coefficient (SHGC) measures how well a product can resist unwanted heat gain. Designing the look and feel of a building’s daylighting is a delicate balance of factors, and SHGC is a primary consideration. Some translucent sandwich panels offer best-in- industry SHGCs with values as low as 0.04—up to 900% improved performance over midrange IGUs. ©2021 ∙ Table of Contents < Slide 42 of 101 > About the Instructor About the Sponsor Ask an Expert Solar Heat Gain Coefficient (SHGC) A fenestration unit that allows daylight to pass through will also induce solar heat gain. Deciding how much solar radiation to allow through requires answering the following questions: What is the climate where the building is located? How energy efficient is your daylighting? How much daylighting do you want? How will the daylighting affect a building’s aesthetics? ©2021 ∙ Table of Contents < Slide 43 of 101 > About the Instructor About the Sponsor Ask an Expert VIDEO: Solar Heat Gain Coefficient (SHGC) The SHGC is measured on a scale of zero to one, with one representing the highest amount of heat allowed into a building through fenestration. A building exposed to intense heat and with little shade requires a lower SHGC, while a higher SHGC would be appropriate for the fenestration of a shaded building in a northern climate. Beyond the obvious climatic conditions, topography also factors into determining the SHGC for a building’s fenestration. Well-planned daylighting considers solar orientation, nearby site features like mountains and trees, or reflections off the surfaces of adjacent buildings, paved surfaces, and bodies of water.

Since the first use of windows, the amount of light entering a building has needed to be controlled. Whether it be preventing excessive solar gain or stopping glare and hotspots, daylight has always been constrained using sunshades, brise-soleil, curtains, blinds, louvers, or shutters. Transparent mediums, e.g., glass, have no built-in filter to control daylight, which is why translucent solutions that diffuse daylighting are popular. When a fenestration unit offers the broad diffusion of light over a large area, it means more usable light penetrates deep into the interior space, allowing excellent visual clarity. Furthermore, it has been shown that diffused daylight offers other benefits over transparent options. This goes from the calming and attractive ambience to enhanced concentration and better responsivity compared to traditional glazing. ©2021 ∙ Table of Contents < Slide 45 of 101 > About the Instructor About the Sponsor Ask an Expert The Power of Diffusion Translucent materials can scatter visible light waves to provide diffuse daylighting to interior spaces, but not all translucent materials produce the same degree of light diffusion even though all can reduce glare. It’s important to have third-party validated measurements of diffusion for accurate daylight simulation of any products being evaluated. Light behavior and material interaction ©2021 ∙ Table of Contents < Slide 46 of 101 > About the Instructor About the Sponsor Ask an Expert VIDEO: The Power of Diffusion In physics, Lambertian diffusion represents the mathematical ideal for light dispersion. Translucent FRP reproduces this effect and creates the ideal daylit environment. Transparent glass with various glazing films/coatings and other translucent materials such as thermoplastics, e.g., polycarbonate, acrylic, and ethylene tetrafluoroethylene (ETFE), aren’t Lambertian diffusers.

It is stronger, lighter, and more energy efficient than look-alike and alternative products. Translucent structural sandwich panels are formed by permanently bonding two specially formulated translucent FRP faces to a grid core composed of interlocking aluminum or thermally broken composite I-beams. Aluminum frames are used because aluminum and fiberglass expand and contract at essentially the same rate, creating a diaphragm action.

What does this mean? Natural daylight is most often considered the best form of illumination for interior fittings and finishes of historic buildings, museums, and galleries because it can reveal the true color(s) of the preserved objects and paintings. But, as we know, natural light is also responsible for the degradation, e.g., fading and cracking, of many materials due to its thermal energy and ultraviolet (UV) rays. ©2021 ∙ Table of Contents < Slide 53 of 101 > About the Instructor About the Sponsor Ask an Expert Museum-Quality Visible Light Translucent structural sandwich panels can block 99% of harmful UV-A (between 315 and 400 nm) and UV-B (between 280 and 315 nm) wavelengths yet transmit the full spectrum of visible light for perfect color rendition within interiors to protect occupants and materials inside the space. In other words, they provide museum-quality light—light without glare or shadows that shields people and objects from harmful UV rays and does not require the use of traditional methods of controlling daylight. ©2021 ∙ Table of Contents < Slide 54 of 101 > About the Instructor About the Sponsor Ask an Expert Optimized Daylighting The random distribution of glass fibers within translucent structural sandwich panels can diffuse large amounts of usable light with a relatively low level of light transmission. Less radiant energy is transmitted, and this, coupled with diffusion, eliminates the hotspots that are so common to other light-transmitting sources. Because the panels throw evenly distributed light further into an interior space, the need for artificial lighting and the loads on mechanical systems are greatly reduced. ©2021 ∙ Table of Contents < Slide 55 of 101 > About the Instructor About the Sponsor Ask an Expert Optimized Daylighting Skylight Here you can see how true diffused Translucent sandwich panels daylight fills the space— even the 8% VLT purple and blue areas are a minimum of 40 footcandles.

Speak to a manufacturer about their custom fabrication capabilities— there are many first-time applications developed by people just like you. When the panels are secured to an aluminum pre-engineered box beam system, span areas in excess of 100 feet (30 m) can be built while providing a clean, finished appearance that is virtually maintenance-free, energy efficient, and highly corrosion resistant. Relying on the structural nature of the panel itself, the fastening system makes the most efficient material use of its aluminum profiles, allows for panel expansion and contraction, and provides a weathertight envelope. ©2021 ∙ Table of Contents < Slide 58 of 101 > About the Instructor About the Sponsor Ask an Expert Aluminum Box Beam System To create a skylight or sky roof using the aluminum box beam system, the translucent panels are overlapped starting at the lower edge to create a shingle effect. This type of construction virtually eliminates leakage because rainwater and snowmelt will continue to flow downslope and will not get trapped in a ridge or joint. In addition, the sealants used will not degrade due to sun/environmental exposure because they remain protected under the aluminum battens. ©2021 ∙ Table of Contents < Slide 59 of 101 > About the Instructor About the Sponsor Ask an Expert Review Question How are translucent structural sandwich panels fabricated? ©2021 ∙ Table of Contents < Slide 60 of 101 > About the Instructor About the Sponsor Ask an Expert Answer Translucent structural sandwich panels are formed by permanently bonding two specially formulated translucent fiberglass reinforced polymer (FRP) faces to a grid core composed of interlocking aluminum or thermally broken composite I-beams. ©2021 ∙ Table of Contents < Slide 61 of 101 >  About the Instructor About the Sponsor Ask an Expert Benefits of Translucent Structural Sandwich Panels ©2021 ∙ Table of Contents < Slide 62 of 101 > About the Instructor About the Sponsor Ask an Expert Thermal Performance The diffuse light-transmitting, structural composite technology of translucent sandwich panels is inherently highly insulating because of its double skin panel construction, which can provide a U-value of 0.23. When aerogel translucent insulation is incorporated into the grid, panel U-factors can range from 0.05 to 0.29. In addition, the panels can achieve very low solar heat gain coefficients, as low as 0.04, which reduces energy usage from heating and cooling loads. ©2021 ∙ Table of Contents < Slide 63 of 101 > About the Instructor About the Sponsor Ask an Expert Thermal Performance To address potential thermal bridges, which can produce localized areas of higher heat transfer, translucent sandwich panel systems employ proprietary thermal break technologies for both the panel and the fastening system. This diagram shows a thermal gradient, generated using a thermal design performance software, to illustrate the effectiveness of a panel’s thermally broken grid core. Not all thermal breaks perform to this degree. It is important to examine thermal break technology when comparing look-alike products. Poured and debridged thermal breaks are dramatically less efficient, resulting in cold interiors. ©2021 ∙ Table of Contents < Slide 64 of 101 > About the Instructor About the Sponsor Ask an Expert Safety and Privacy Creating a safe environment in every building and public space is essential to helping people feel welcome and motivated to socialize, learn, and be productive. Increasing the level of safety in our buildings and public spaces can consist of measures that include utilizing blast or wind-borne debris- resistant materials, well-designed entry and exit points, and increased lighting in common areas and walkways. Translucent sandwich panels offer line-of-sight protection or total visual privacy from the outside. Daylight is allowed into a space, but the occupants are shielded from view. Nighttime illumination of entryways and exterior façades provides a friendly, safe environment via backlighting that emits a soft glow without light pollution. ©2021 ∙ Table of Contents < Slide 65 of 101 > About the Instructor About the Sponsor Ask an Expert VIDEO: Security and Blast Protection An important aspect of designing with translucent structural sandwich panels is their innate shatter/impact proof nature, making them suitable for use in areas of high security or those at risk from blasts. They are increasingly used in airport design and other areas deemed as high risk, high value, or target rich. These include extreme weather events and man-made risks such as terrorism. Systems designed with security as a priority meet the requirements of UL 972, “Burglary Resisting Glazing Material,” and ASTM F1233, “Standard Test Method for Security Glazing Materials and Systems.” Blast-resistant systems meet the US Department of Defense (DoD) UFC 4-010-01 Anti-Terrorism Force Protection (ATFP) criteria.

Daylight modeling allows architects and designers to tailor visible light transmission (VLT), thermal insulation values, and solar heat gain control properties for a project based on light level targets, climate zones, and building type, as well as building orientation and microclimatic considerations. Modeling can also identify potential areas where glare would be an issue. Introducing diffuse, full-spectrum natural daylight into educational facilities provides students with a well-lit environment that supports learning and their well-being. The elimination of irritating glare and shadows also has important implications for the playing surfaces in sports and recreation venues and the safety of pools. Diffuse light-transmitting daylighting systems also create glare-free, private environments that support people in commercial buildings, retail spaces, industrial plants, places of worship, and cultural centers. Translucent sandwich panels are engineered to withstand the toughest environments, from hailstorms and hurricane winds to high snow and drift loads. When they are secured to aluminum box beam members, a rigid, cohesive, prefabricated, prefinished structure can be delivered to a jobsite ready for rapid installation. This single-source design solution from the curb up reduces labor and on-site trades, saving time and money. ©2021 ∙ Table of Contents < Slide 100 of 101 > About the Instructor About the Sponsor Ask an Expert Conclusion If you desire AIA/CES, state licensing, or CE credits for another organization, please click on the button to commence your online test.
