Liveroof Patented Hybrid Green Roof Systems

Commercial boilers are pressurized systems that burn combustible fuel or use electricity to heat water that is used to provide heating in your building. … Inside the boiler, the burners or electric coils generate heat that is transferred to the water by the heat exchanger. SolarCity’s loan program also allows it to enter states such as Georgia and North Carolina that ban third-party ownership of rooftop solar systems. With SolarCity’s MyPower loan program, homeowners who qualify can finance rooftop solar systems at a rate as low as 4.5 percent. SolarCity became the largest U.S. supplier of rooftop solar power by offering leases for no money down. Today it will begin offering 30-year loans in eight states that are repaid through borrowers’ power bills, the San Mateo, California-based company said today in a statement.

APP MB roofing systems are typically composed of a base sheet, an interply sheet, and a cap sheet. The cap sheet is either heat-welded (i.e., torched) to the base sheet, or it is adhered in cold adhesive. The following membranes are typically used on low-slope roofs, but may also be used on steep-slope roofs. When used on steep-slopes, the system’s fire resistance may be reduced and/or special precautions may be needed when used on steep-slopes.

Intensive green roofs weigh from 35 pounds to beyond 100 pounds per square foot when dry – it is all a matter of the soil depth, which is affected by the amount of mounding that is used. Tray systems are not a viable option for intensive roofs due to the weight; therefor, a significant amount of attention must be paid to the various waterproofing and root barrier details. Extensive green roofs are generally made up of a very thin layer of soil or other planting medium with shallow-root plants like sedum, mosses, and grasses. Perhaps the most important benefit of green roofs is that they can reduce the amount of and improve the quality of stormwater runoff from a building site. The soils of a green roof will capture a significant amount of stormwater, which is absorbed and used by the planted material. Any water that is released is done so at a slower and more consistent rate, which helps prevent flooding and runoff that can be destructive to the surrounding environment.

This happens because the soil media used in construction will soak up some of the water as well as slow down how quickly watersheds from the roof. The trend of sustainable architectureis happily growing in popularity. While there are many different techniques and designs incorporated in these more eco-friendly facilities, one of the most impactful is the vegetative roof system.

When developing the design for the new building, the architect, PF&A Design, was challenged to create a high-tech aesthetic concept as opposed to continuing to use a brick facade. Complete portfolio of walkways, ladders, towers, bridges, and platforms for constructing a rooftop pathway. Black & Veatch has assisted owners in developing and building more than 3,000 megawatts of solar facilities. IB Roof Systems is proud to work with, be a part of, and have our products and systems certified with these industry organizations.

While the modified bitumen systems are related to BUR, the other low-slope alternatives are radically different. Along with new choices of membrane materials, plastic foam roof insulations also emerged in the 1970s. The abundance of materials and applications from which to choose has created a complex and challenging subject matter. In a typical rooftop unit, the compressor is located at one end of the cabinet, and the condenser coils are wrapped around or in close proximity to it. Rooftop units that also provide heating often contain a gas heat exchanger downstream from the evaporator fan. components are assembled within one cabinet, it’s considered a packaged unit.

However, ground mount arrays aren’t bound by this and can align to the perfect angle to get as much sun as possible. Rooftop HVAC units are usually installed on the roof of a building, though they can also be installed on a slab at ground level. Commercial buildings with flat roofs have ample space atop the structure for installation of HVAC equipment. On the roof, HVAC systems are protected from theft and ground space is conserved. Deck-Frame is the first metal building roofing solution designed specifically to incorporate a membrane roof with a metal building.

An extensive green roof can reduce sound from outside by 40 decibels, while an intensive green roof can reduce sound by decibels (Peck et al. 1999). A green roof system is an extension of the existing roof which involves, at a minimum, high quality water-proofing, root repellent system, drainage system, filter cloth, a lightweight growing medium, and plants. Trane ZRS offers the connectivity small buildings have been searching for by offering a pre-engineered system compatible with Trane’s full portfolio of light commercial units and backed by the expertise of Trane engineers.

If an emphasis on sustainable roof design is desired, sustainable design criteria can become major factors in the selection process, depending upon the degree to which sustainability is pursued. At the very least, the selected system should be thermally efficient, with consideration given to R-value, reflectivity and emissivity. And for those buildings that are intended to have a service life in excess of 20 years, a system with enhanced durability should be selected to reasonably maximize the life of the roof to the extent that the budget allows. For most projects, the costs associated with eventual tear-off and disposal are seldom considered. Because some systems are inherently more difficult to tear-off than others, LCC analysis should consider this issue. Also, it may be possible to salvage or reuse some of the system components.

The system is fully customizable for your specific fall protection need and is easy to install. The RoofSafe® Lo-Profile Rail is the most effective solution for fall risks associated on a jet bridge. Established in 1983, Rooftop Systems Inc. is one of the leading manufacturers of Commercial Air Conditioning Accessories in the United States.

“We don’t need mandates,” said Lauren “Bubba” McDonald, a member of the Georgia Public Service Commission, who is widely credited with helping jumpstart the state’s solar industry. The Austin Energy contract opened a market for big solar in sunny Southeastern states, Jim Hughes, chief executive of utility-scale solar developer First Solar told investors in April. They did a great job and I would hire them again to do siding and other projects. I hired them to replace my roof and they did a great job at a reasonable price.

The owner should understand that a green roof requires routine landscape maintenance, which can vary from occasional to regular and can add a significant ongoing cost. In addition, space should be allocated for storage of maintenance materials. For instance, it may be inconvenient to take a lawnmower to the roof on a weekly basis if there is an area of grass that requires regular trimming. There are a number of things to consider when designing for a green roof. This is especially true of intensive green roofs, which can have soil that is two feet deep or more.

The best course of action is to schedule a monthly, quarterly, or semi-annual maintenance appointment. The RoofSafe® Rail is best suited for modern building projects and roofs that are pitched at more than 15 degrees. It provides a sound anchorage point and fall protection safety that does not flex. In the event of a fall, the fall protection rail distributes very low loads to the roofing structure and does not deflect. The RoofSafe® Rail offers excellent functionality through it’s free flowing attachment carriage and is capable of navigating corners and changing of directions. The PR-Series of packaged rooftop systems are designed to provide fresh air for critical facilities and features air source cooling-only, air source heat pump, and boiler/cooling tower or geothermal water source heat pump.

The phenomenon leads to zones of higher temperatures around urban areas. We have attempted to address this by using high albedo materials, but this simply reflects the radiant heat to other materials that can absorb it an release it in the evenings. The natural plantings and soils in green roofs mitigate the heat island effect by better modulating temperature fluctuations caused by radiant heating during the day. This leads to lower ambient temperatures in the microclimate surrounding buildings.
