Work Groups/WG 7 - Energy Harvesting

Chairman: K. Wayne Lee


The urban cityscape is filled with man-made materials that absorb the suns light. Darkly colored roads and roofs have replaced surface area which was once predominantly vegetated lands. Many of these man-made surfaces are also impermeable and typically dry. For these reasons summertime ambient temperatures in cities are typically warmer than those of rural areas. On a sunny summer day city temperatures can be up to 4oC (8°F) higher than rural areas. This phenomenon is known as the heat island effect and it can have several negative impacts to the environment and human health.
Heat island can lead to increased air conditioning use which puts a strain on a city energy grid. This increased demand for cooling can amount to a 5-10% increase in peak electricity. One estimate shows that temperature increase from heat island can account for up to 1.5 gigawatts of energy. This increase correlates to increased emissions from municipal power plants. Therefore the heat island effect contributes to problems with air quality including smog formation.
Cool pavements are defined as a class of materials that increase reflectivity of sun light without losing their structural properties. Cool pavements use different types of amendments to keep their surface temperature low. There are many other benefits associated with cool pavements as well, e.g., longer lifetime of pavement, lower initial costs of the asphalt binder, and savings on street lighting and signs, etc. Some examples of cool pavements include: modified asphalt pavements using lightly colored aggregate; resin based pavement; permeable, porous and/or rubberized pavements; chip seals with lightly colored aggregates.
Recently, more exciting approaches to reduce heat island effects and global warming have been identifies, i.e., solar energy harvesting and conversion with potential economic efficiency substantially beyond that of current technology. Thus, there is a need to investigate novel methods to harvest solar energy from road pavements by asphalt technologists.

Strategic Plan
To investigate novel methods to harvest solar energy from roadway pavements, following tasks can be carried out new work group:

(1) Review literatures and existing practices to investigate novel methods to harvest solar energy from asphalt pavement.
(2) Generate different approaches to capture solar energy from asphalt pavements.
(3) Formulate conceptual design of systems to generate electricity.
(4) Prepare the feasibility study report for the detailed and comprehensive study.
