Track 1, Sustainable Homes: Hot Attics — Turning a Problem into a Resource
Christopher M. Roseberry, Ph.D.

photo of Christopher RoseberryIn the interests of sustainability, existing residences need to be modified for better energy management. However, most households are not equipped to make use of solar energy or heat from cogeneration. The seasonally hot attic space of a house is generally an underexploited source of low-grade heat. The roof surface and attic space may be considered a large, low efficiency solar collector that uses air as the working fluid. The primary factor determining the expense involved with most solar heating and power systems is that they require a large amount of new material to present a large surface area for sunlight absorption. As compared to conventional solar collectors, using the hot attic space requires a relatively modest investment. It has been demonstrated that the installation of a simple heat exchanger and blower can meet much, if not all, of the heating requirements of a typical backyard swimming pool. This approach could be applied to most of the seven million swimming pools in the U.S.

Track 2, Zero Waste: What? Zero Waste in Construction?
Karen Benson

Construction generates a huge amount of waste by the nature of the process of manufacturing building products, then turning products into buildings. What steps are being taken in the design and construction of school buildings to reduce and eliminate waste? Is it possible to get to zero waste? What's being done in North Texas to get to zero waste, and what are the challenges? Are there opportunities for new businesses and jobs? This overview of the industry will include a discussion of the political economy of waste in the Metroplex, what green building rating systems like LEED and CHPS do to change the market and the processes used in construction, and how your school can make a shift to zero waste in construction and operations of buildings.
