Within the wide use of precast concrete technology... does the precast concrete considered energy efficient?
Dear Segun Michael Abegunde ... thanks for answering..
There are many idea discussed in this subject.. many of them consider it not...
Dear M. A. A. Al- Fatlawi ... Thanks for joining our discussion...
Dear
Kindly be specific, during manufactur, it is not considered an energy saving. During installation and erection it is also not energy saving. During the use as residential or commercial use, it is also not energy saving.
Energy efficient mainly depends on manufacturing raw materials and also on type of curing.
Dear Anil Kumar Thakur ... Thanks for answering..
So did you think that precast concrete could be considered energy efficient?
Dear Hussam:
Regarding the energy performance of precast concrete structures, the most energy efficient component is the precast concrete insulated sandwich panel which features an insulated core sandwiched between concrete layers. This component can be used a loadbearing wall panel as well. The energy efficiency depends on the thickness of the insulation layer, as well as the connectors used to link the concrete layers. In the USA it has become very popular and competes effectively with other systems used for commercial buildings.
For your benefit I am including a couple of links each for pages from the Precast/Prestressed Concrete Institute (PCI) and the National Precast Concrete Association (NPCA), as well as a link to a PCI Committee State-of-the-Art Report.
