This webinar was co-sponsored by ASCE's Geo-Institute (G-I) and ASCE Continuing Education
Instructor: Guney Olgun, Ph.D.
Course Length: 1.5 Hours
Purpose and Background
There is a rapidly developing trend around the world to explore alternative energy sources. The main driving forces are growing global energy demand, depleting natural resources and the potential effects of greenhouse gas emissions from fossil fuel consumption. Geothermal energy is one of the promising renewable sources that can be utilized to offset such trends. To date, the use of geothermal energy has been limited mainly to certain localized areas where it is used for either district heating and/or electricity generation. However, the constant temperature and heat storage capacity of near-surface soils in any region represent a tremendous potential of stored energy that can be used for heating and cooling of structures. This webinar will summarize the general concepts of using near-surface geothermal energy for heating and cooling of buildings, as well as explain how pile foundations can be utilized as heat exchangers for this purpose. Furthermore, the geotechnical engineering design challenges are discussed in connection with the recent research on this topic.
Primary Discussion Topics
The speaker will discuss:
- Ground-sourced heat pump systems
- Energy piles
- Other thermo-active foundation systems and applications
- Design considerations of energy piles
- Findings from ongoing research and implications for design
- Design recommendations to account for heating/cooling induced pile response
