Building operations account for about 40% of total US primary energy resource consumption.
Approximately 30-40% of this energy is consumed for heating, ventilation, and air conditioning.
A common strategy to improve building energy efficiency is to use materials with a large thermal mass such as concrete or brick.
While these materials can store large amounts of energy per unit mass, they operate passively.
On the other hand, embedding phase change materials (PCMs) in building elements add an active dimension to the thermal behavior of building envelope.
Indeed, by reversibly undergoing melting and freezing during the course of a day, PCMs are able to actively and adaptively absorb and release their latent heat.
This, in turns, reduces and delays the thermal load on the building and reduces the cost for HVAC operations.
This seminar will present experimental and modeling efforts to predict the effects of microencapsulated PCMs on the thermomechanical properties of cementitious composite building materials.
It will also assess the potential seasonal and annual energy and cost savings of buildings made with such PCM-composite envelopes in selected climates.
Finally, it will discuss a figure of merit and design rules for the implementation of smart multifunctional PCM-composite building envelopes.
