Metal roofing provides several sustainability benefits and can help buildings earn points in the LEED green building rating system. It has high solar reflectance which can reduce cooling loads in buildings and help mitigate the urban heat island effect. Metal roofing is durable with an expected lifespan of 40 years, requiring little to no maintenance over its lifetime. It is fully recyclable at end of life and some products contain recycled content. When used in conjunction with solar PV panels, metal roofing provides an ideal substrate to generate renewable energy and help buildings achieve energy independence.
Explore all of the Sustainable Design options metal roofing has to offer offer! This presentation walks you through topics such as: Solar Reflectance, emittance, recycled content, LEED credits and the use of Solar and Metal roofing. Build green with metal roofing!

The latest advent of innovative ideas and thoughts popping up as green roofing in the minds of Engineers and professionals. The ever changing trends of roof makeover in eco-friendly zones made it a sturdy and diverse option for many homes and buildings.
Ever wondered why some homes feel more comfortable than others? Want to re-discover what our ancestors knew about home building that works in concord with site, climate and orientation? Want to visit a honest-to-goodness passive solar home? Join us as we investigate the concepts and practice of passive solar buildings. Whether you're building new, remodeling or want to improve the energy and comfort performance of your home, this workshop is for you.
In the last five years, the term green roof has taken on ecological and social significance beyond its seemingly simplistic description, this term has become an epithet for the reduction of pollution and improving urban environment, for large scale mitigation of storm water runoff, and for maximum utilization of urban land.
Erbil the capital city of Kurdistan region is facing a lot of environmental problems such as waste water treatment, water supply, land preservation, air and noise pollution due to the increasing number of cars, in addition, interestingly recent statistics suggested that the percentage of green areas in Erbil is approximately 6.5%, while according to international standards 30% of urban areas should be green.
Green roofs infrastructure on the other hand promises to become an increasingly important solution for building owners and community planners which provides a significant numbers of social, environmental and economic benefits that are both public and private nature.
Research problem is the ambiguity of green roofs implementation techniques in the region and the goal is initiated to determine the obstacle and challenges of green roofs implementations in Erbil city as case field by analyzing international experiences and concluding Erbil’s green roofs criteria.
Space is a concern for every urban gardener. You can take your garden to the next level, or start one where you had not thought it was possible! We'll survey growing techniques for vertical surfaces both indoor and out-from vine veneers to living walls. Learn about a variety of vertical planting systems and the appropriate plants for each.
This is the presentation created for the class I offered on June 3, 2015 at the Brooklyn Botanic Garden.

19. Life Expectancy
Based on a study conducted by Ducker in 2003, metal
roofs have a significantly longer expected service life
than either asphalt or single-ply roofs. According to
Ducker findings, metal roofs are expected to last 17
years longer than asphalt and 20 years longer than
single-ply.
Expected Roof Life Years
• Metal: 40
• Asphalt:23
• Single-ply:20
Due to its credible long life and documented durability,
metal roofing makes an attractive investment.
22. Life Cycle Cost
• According to Ducker’s 2004 research study,
the life cycle cost of a metal roof is
significantly less than an asphalt or single-ply
roof.
• The expected life cycle cost of metal roofs
reported in this study is 30 cents per square
foot per year, asphalt is 37 cents per square
foot per year, and single-ply roofs is 57 cents
per square foot per year.

35. What Does a 100kW PV System Mean?
SUNRISE SUNSET
•As the sun rises the photovoltaic
cells begin to produce electricity at
a low level
•At noon a 100kW system is
producing at its optimum output
•In California the average 5 peak
sun hours a day
•Therefore, we could say that this
100kW system produces
500kWh/day (100kW x 5 hours =
500kWh)
•Depending on your energy usage
profile a 100kw system could
produce all or part of your total
energy needs
38. Net Metering
• Under State NET METERING agreements The PV power is
connected to run your meter backwards with the energy you
produce.
• The local utility and the third party monitoring company track
each kwhr your system produces
• Credits are issued monthly by the utility for energy produced
• Credits cannot exceed your historical usage annually.
• Performance based incentives are monitored and paid to the
system owner utilizing this process.
40. How is the Energy Production
Monitored?
• Third party companies provide web based real
time monitoring capability.
• Service cost is integrated into project O&M
cost.
