Endive cold-storage building features energy savings

By doing so, California Vegetable Specialties can avoid the higher-priced Pacific Gas & Electric peak electricity rates.

The walls are composed of two layers of foam panels, between which expanding polyurethane foam is injected.

Then about 3 inches of concrete is applied to both sides of the wall.

Not only does this help maintain more stable humidity and temperature inside, but it also has a lifespan of at least 200 years and an earthquake seismic rating similar to those of police departments and hospitals, Burda said.

Concrete envelope design isn’t new and has been used since 1994 on a handful of wineries, Burda said. In those structures, straw bales provided about R-87 insulation.

This is the first time foam has been used, “and it worked like a charm,” he said.

The energy savings will pay off the building in about 15 years, Burda said.

If those energy numbers are correct, it will change the whole industry of cold storage.

High R-values are easily achieved with a variety of existing technologies. The only hard part is getting people to pay for the insulation and installation.

Seems like under 3 year ROI and pays for the entire building with energy savings in half the mortgage should get people to pay for insulation and installation.

Energy prices aren't going down. Seems like a no brainer with those kind of savings.

I am continually amazed at the long term cost savings featured being designed into buildings by Integrated Structures. Gary, Cullen, Jenny and the others they work with at Integrated Structures are absolutely amazing in what they are able to design for their clients.

With a little digging I was able to find the website for the wall system used at CVS: http://energymasswall.com Really interesting stuff... and it doesn't look like it would be that much more expensive than a typical building because they are using mainly off the shelf components...
