Contact information for GRHC members and GRPs can be found in the Green Pages Industry Directory. A Green Roof Professional would be able to advise you on suitable plants and design of the plantings. Green roofs can sustain a variety of plants and invertebrates, and provide habitat for various bird species. By acting as a stepping stone habitat for migrating birds they can link species together that would otherwise be fragmented. Green roofs can also help reduce the distribution of dust and particulate matter throughout the city, as well as the production of smog.
Ground mounts on the other hand, might take up land that could be used for recreational activities. Solar panels can withstand hail the size of a golf ball striking the glass at 50mph but it’s important to reduce the risk of damage as much as you can. While rooftop solar is common for homes and businesses alike, sometimes rooftop systems are not ideal. A roof needs to meet multiple physical requirements in order to practically support a solar system.
Intensive green roofs offer a great potential for design and biodiversity. This system supports everything from small personal/home gardens to full scale public parks. Plant selection and design greatly affects the maintenance required for the upkeep of these roofs. Rooftop farms, urban roof farms or vegetable farms on roofs are clearly intensive green roofs and require higher nutrient applications and focused maintenance. Admirals Bank offers loans of as much as $40,000 for renewable energy systems and in June announced a partnership with SunPower Corp., a solar-panel manufacturer and rooftop system provider. SunTrust Banks Inc.’s LightStream unit offers financing for rooftop power at rates that start at 4.99 percent.
Flat roofs are an attractive aesthetic choice that give homes a unique form. If you love the landscape or cityscape around your home, a flat roof can help complement that without obscuring the view. The forms below apply to roof-mounted photovoltaic systems for generating electricity. With fast installation and optimal design, the TRAC Rail™ is the perfect system solution to component problems.
LiveRoof offers the convenience of delivery and speed of installation of green roof modules—without grid lines or compartmentalization of soil. It’s important to design and size these systems appropriately and crucial to properly service these systems for maximum useful life as well as efficiency. Alphine Air specializes in both design/installing and maintaining these systems.
The product also features direct drive supply and exhaust fans and final filters not mounted in the roof curb. Factory-installed options include supplemental heating, dehumidification, ventilation, corrosion protection, electrical and refrigeration control. A rooftop photovoltaic power station, or rooftop PV system, is a photovoltaic system that has its electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. The various components of such a system include photovoltaic modules, mounting systems, cables, solar inverters and other electrical accessories. Trane rooftop units and systems are unitary systems manufactured in various configurations providing single or multi-zone heating, cooling, and ventilation.
Blue Oak engineers offer specialized site visualization and energy production modeling for clients and investors. We use our extensive commercial rooftop solar industry knowledge to assess roofing and membrane requirements, and whether your building’s roof can support a PV array. This is also the stage where Blue Oak Energy secures permits and draws up construction documents. As always, we take into account any client concerns and preferences. Integrity Air Conditioning, LLC has over 75 years combined commercial rooftop experience with business and residential customers, including townhomes, condos and any home style that has units on a roof.

For facilities with multiple packaged units, comfort zoning can improve overall efficiency and increase flexibility to tailor temperature setting for specific building areas. These pre-assembled units contain all of the major components found in more complex systems. The break-even cost for PV power generation was in 1996 found to be relatively high for contribution levels of less than 10%. While higher proportions of PV power generation give lower break-even costs, economic and LFC considerations impose an upper limit of about 10% on PV contributions to the overall power systems. In this mechanism, the excess solar power generated is exported to the electricity grid.
Installation of a stone-protection over the membrane would avoid aggregate punctures. To avoid surface cracking from ultra-violet radiation, a field-applied coating (such as aluminum-pigmented asphalt, asphalt emulsion, or acrylic) may be applied. Cap sheets with factory-applied surfacing of granules or metal foil should be specified. Therefore, BURs are surfaced with aggregate, a field-applied coating or a mineral surface cap sheet. If aggregate is specified, wind blow-off should be considered, see Wind Safety—Roof Systems.
MBCI offers a series of roll-up doors to service the self-storage and commercial markets. Learn more about the main things to consider when choosing a metal roof with regard to roof slope, including building codes and minimum slope requirements. Lightweight rooftop support requiring no tools or fittings making installations quick and easy. nVent CADDY Pyramid Rooftop Anchor Systems help ensure the safety and protection of your rooftop mechanical and electrical equipment applications. A fast, flexible and innovative system for supporting heavy-duty mechanical services on rooftop surfaces.
Variable-speed was initially attempted with induction motors, but the performance suffered due to drive losses. Variable-speed compressors offer extremely precise temperature and humidity control. With low in-rush and a high-power factor, there are great benefits in applying variable-speed, the biggest of which is performance.
Building owners have two options available to them when it comes to aging rooftop equipment—fix on fail or planned replacement. The “fix on fail” option creates unplanned events that create equipment downtime and the resulting discomfort of occupants and tenants. Enough downtime and tenant dissatisfaction can have the end result of lost revenues, which can add up to real money. If your RTU is failing, My Plumber PLUS will have you back up and running quickly! Our technicians are knowledgeable in service and repair for systems in all makes and models.
