    • Remove facet Reduces heating and cooling loads
View: GridList

Before specifying efficient heating and cooling equipment, it’s important to do what we can to reduce heating and cooling loads. Insulation is one of the key products to consider here, but because there are so many insulation products on the market, we look for additional benefits. Examples include cellulose insulation with recycled content, mineral wool insulation with no flame retardants, and fiberglass insulation with no formaldehyde binders. Other products in this area are high-performance windows and glazings, products that contribute to building airtight envelopes, products that reduce thermal bridging, and window-retrofit products.

With products in this area under constant development, we are always refining our approach. For example, as we have learned about insulation products with hazardous flame retardants and blowing agents that have high global warming potential, we have removed those products from GreenSpec, pending manufacturing changes. We encourage building professionals to pressure manufacturers for those changes through specification language and purchasing decisions.

    Testo makes a dozen models of ergonomic thermal imaging cameras for building, electrical, and mechanical analyses. The models use 160 x 120, 320 x 240, or 640 x 480 detector arrays and incorporate a digital camera so they can capture both standard and thermal images simultaneously. The Testo 875 has a thermal sensitivity of 50mK (it can distinguish temperature differences between 11.25°C and 11.75°C), and for greater sensitivity the 890-2 has 40mK and includes LED lighting and voice recording. Each model comes with a number of options.

  • ENRGY 3.E Polyisocyanurate Board Insulation
    Johns Manville Corporation
    ENRGY 3.E is a polyisocyanurate foam board insulation with no halogenated flame retardants—the first in the industry. Instead of using the standard TCPP, or Tris (1-chloro-2-propyl) phosphate, ENRGY 3.E uses a non-halogenated organo-phosphorus monomer to provide an insulation board with a Class A fire rating. The chemistry of this is proprietary and has not been evaluated by third-party groups, but Johns-Manville has provided information indicating that it is a safer alternative to TCPP and binds much more directly to the foam insulation. This roofing insulation has glass reinforced faces, an aged R-value of 5.7 per inch, and is available in Grade 2 (20 PSI) and Grade 3 (25 PSI) densities.

    LouverShade
    Louvershade is a two-part interior shading system consisting of louvers and solar-shading fabrics, where the upper reflective louver section bounces light into the room for improved daylighting while the lower fabric section provides shade and glare control. Various control systems are available for specific lighting needs, from basic solar sensors to full integration with building automation systems. The aluminum louvers are available in slat sizes from two to six inches; more than 25 fabric color options are available, including those that reflect light outward; and control options include individual or group controls, timers, solar trackers, photovoltaic power, and more.

    Proctor Engineering Group, Ltd.
    Proctor Engineering Group manufactures products that improve the performance of air conditioners in dry climates, including the Western Cooling Control (WCC) system. Air conditioners are designed for humid climates, but in dry climates dehumidification is less important so the WCC allows the fan to run longer than standard AC controls to take advantage of cooling that is still present after the compressor turns off, saving up to 15% in energy, according to the company. The company also offers its Concept3 variable speed, electronically commutated motor and controls for furnaces and air handlers, which can reduce fan energy consumption by 50%. It can be climate optimized for greater dehumidification in humid climates and better cooling in dry climates, and it can accept humidistat input for improved efficiency in mixed climates.

    Cellucrete
    Cellucrete is certified to apply the Elastizell Roof Deck System, which consists of a low density foamed cement slurry cast over embedded EPS insulation up to 12" thick (R-4/inch). The slurry is air-entrained on site with proprietary protein-stabilized surfactants using specialized foaming and mixing equipment. The use of other additives may be specified. Cast densities from 30–50 pcf for various applications have R-values ranging from 0.86–1.8 per inch. Elastizell insulating concrete is applied over fluted metal, concrete, or wood decks; it fills depressions and flutes to eliminate potential air and water channels. The product is positively sloped during installation to achieve proper drainage and eliminate ponding. Then, a built-up or single-ply roofing membrane is applied directly to the sloped surface. The EPS insulation sandwiched within the insulating concrete is protected during future roofing replacement.

    Wausau Window and Wall Systems
    Wausau’s S.E.A.L. (sound, energy, air, and light) window system installs as a retrofit on the interior of existing weather-tight commercial windows or curtainwalls to improve their thermal and acoustic performance. They have a thin profile to fit within existing frames and can be accessed for cleaning via a lockable side-hinged mechanism. A variety of glazing options are available, including laminated glass, polycarbonate, dual-glazed, low-e coatings, and security glazing. Performance of the window assemblies will vary depending on existing glazing and frame. Venetian blinds that sit between the existing window and S.E.A.L. system can also be specified. Wausau recommends a sample S.E.A.L. window be installed for a “seasonal cycle” to ensure that the system will perform as intended. S.E.A.L. comes with a limited 10-year warranty.
