Low exergy (LowEx) building systems create more flexibility and generate new possibilities for the design of high … performance buildings. Instead of maximizing the barrier between buildings and the environment using thick insulation, low exergy … sources” reduces exergy use, and thus primary energy demand. LowEx systems provide many heating and cooling methods for …

The Active Low Exergy Geothermal Insulation Systems (ALEGIS …) minimizes exergy demand and maximizes the use of renewable geothermal heat from the ground. A fluid is pumped into a small pipe … exergy input. We present an overview of the operation and analysis of our low exergy concept and its modeled performance. …
