7:00 to 8:30 PM
Granite Reef Senior Center
1700 N. Granite Reef Road​​


Are you considering a new roof in the not too distant future? What are your options for durability, environmental performance and curb appeal? Did you know 43% of all electricity consumed in Phoenix metro area homes is used for air conditioning? Cool roofs reduce energy use, ambient air temperature, air pollution, greenhouse gas emissions, and improve human health and comfort.

Cool roofing is one of the hottest topics in the building and construction market. Learn what a cool roof is and about the many types of cool roofs available, such as foam, tile, metal and asphalt shingles.

Hear from George Daisey, research scientist for Dow Chemical as he begins with a “Cool Roofs 101” overview. Tyler Allwood from Eagle Roofing Products will then zero in on steep-slope roofs and discuss the inherent energy efficiency of various steep-slope roof products, with specific attention to concrete and clay roof tile. Tyler will present recent improvements in roof product design and installation systems that can improve efficiency.

George Daisey will discuss low-slope roofs and the various types of flat roofs and cool roof options. You’ll hear about cool roof membranes and coatings and why they are not just “paint on a roof.” The evening will close with an overview of global initiatives, stakeholder organizations and resources where you can learn more about these evolving technologies to help reduce summer cooling costs and mitigate the urban heat island effect.

Season Schedule 2014-2015

November 6, 2014 - Green Home Rating Programs:  Scottsdale Green Building, ENERGY STAR for Homes, and LEED for Homes

Green building programs have evolved over the last 15 years as a whole-systems design approach to minimize the environmental impacts of buildings including energy, water, materials, and indoor environmental quality. Since 1998, over 1300 green homes have been certified under Scottsdale’s green building program. What does this mean? Does it make a difference? Can we do better? Come hear about newly improved green building certification programs, their benefits and differences, including Scottsdale’s regionally derived rating program, Energy Star 3.1, and LEED for Homes v4.

December 4, 2014 - Energy Disclosures in the Marketplace: Building Economic Value while Reducing Energy Costs

Energy efficiency is widely recognized as the most cost-effective way to reduce reliance on non-renewable fuel sources and avoid the costly development of more power plants. While energy codes have made important strides over the last decade for new construction, benchmarking and disclosure programs have gained prominence for existing buildings. Hear about these programs and important links that can drive the real estate market towards greater energy efficiency, comfort, and value for existing homes and businesses.

February 5, 2015 -Edible Landscapes and Urban Gardening

Join urban gardeners as they share the benefits and how-to's of growing your own healthy food, herbs, edible flowers and fruit trees in our desert environment. Learn about our planting and harvesting seasons and how easy it is to raise chickens in your back yard. Find out about the wide range of community gardens available for you to participate in and how school gardens provide students with valuable skills. Come join in the conversation and be inspired to grow.

March 5, 2015 - Tiny House Movement

This is a social movement where people are downsizing the space that they live in. The typical American home is around 2600 square feet, while the typical small or tiny house is around 100-400 square feet. Tiny Houses come in all shapes, sizes and forms but they focus on smaller spaces and simplified living. People are joining this movement for many reasons, but the most popular reasons are because of environmental concerns, financial concerns and seeking more time and freedom. Hear from several local tiny house advocates about the choices they’ve made in pursuing tiny house living.

April 2, 2015 - Using Smart Technologies to Manage Energy and Water Use

Can energy dash boards, smart thermostats, integrated lighting controls and high efficiency plumbing fixtures make a difference in resource depletion and the unintended consequences of growth and development? Hear about new and cutting-edge technologies that reduce our resource consumption, curtail our reliance on non-renewable resources, improve comfort/convenience, and lower our operation costs.

May 7, 2015 - Cool Roofs in the Urban Desert

Did you know that 43% of all electricity consumed in Phoenix metro area homes is used for air conditioning? Cool roofs reduce energy use, ambient air temperature, air pollution, greenhouse gas emissions, and improve human health and comfort. Learn about cool roofing strategies from solar reflective surfaces to radiant barriers and attic ventilation techniques.

June 4, 2015 - Green Innovative Built Projects

Who are some of the local creative agents creating new building prototypes for the 21st century? What are the innovative features? Come see and hear about successes with innovative residential and commercial projects that exemplify principles of resource conservation, energy independence and healthy living.
