This product is a zip file that contains files that consist of PowerPoint slides synchronized with the audio-recording of the speaker, PDF files of the slides, and audio only (mp3 format) as noted. Radiant cooling and heating systems are a natural match to ground-source heat pumps as their temperature ranges for heating and cooling are very moderate and allow highly efficient operation. The application of a high-mass radiant heat transfer system with predictive control significantly reduces peak HVAC loads and reduces energy use.
