Thanks to new laws, buyers and tenants of large buildings in some areas are entitled to know a building's energy score before they complete their purchase or lease. How long before the U.S. catches up to Europe, where buildings will be labeled according to their energy consumption? Is simply reporting a score meaningful, if there aren't also requirements to improve energy efficiency? Can cities achieve their carbon-related goals without imposing both kinds of rules on businesses? Denis Du Bois interviews Phil Bomrad, Director, Building Technologies, Siemens. (podcast)

Southern California Edison has launched one of the most ambitious solar initiatives yet. It involves using the roofs of commercial buildings to develop renewable energy resources. Building owners get paid to host the solar arrays on their rooftops, and the utility takes all the risk. Where else is this kind of program happening? Why would a building owner choose this over the other alternatives for rooftop solar? In this month's briefing Denis Du Bois and guest co-host Stephen Lacey decipher the impact for owners, tenants, and solar companies. Denis interviews the corporate sustainability executive for AMB Property Corporation, who just joined SCE's new program. (podcast)

Imagine a building so energy efficient that it can generate what power it needs with the solar modules on its own roof -- a net zero energy building. It's not a pipe dream. We've been building them in the United States for a decade. The U.S. Department of Energy wants the "ZEB" to be the standard for new buildings. Why is it important to match renewable energy output with the demand for power on a building-by-building basis? And after ten years of zero-energy design, why do we only have eight buildings to show for it? In this month's briefing Denis Du Bois talks with David Orr, who designed and built the largest zero-energy building in the U.S. If you think that's cool, wait until you hear what Orr is doing for an encore.

What do Seattle, Austin and New York have in common? They've all enacted regulations to expose energy-wasting buildings. Owners of large buildings will have to disclose their energy scores to prospective buyers, tenants and lenders. Similar laws have been passed in three states -- and more are on the way. In this month's briefing we explore what's driving these mandates, and how they affect building owners and tenants. Some building owners are making improvements now, to raise their energy scores before they're made public. What's the business case? We'll learn about that, as well as where are the best places to look for low-cost and no-cost ways to boost a building's efficiency score. (podcast) (transcript)

In the 1970s, American utilities started burying cables to avoid unisghtly poles and vulnerable overhead lines. It soon became common practice to also bury privately-owned power lines under corporate campuses, universities, hospitals and factories. Now there are billions of feet of underground aluminum and copper cables nearing the end of their 25-year lifespan. One company has invented a way to rejuvenate cabling and extend the life of its insulation. Novinium treats the cable by injecting chemicals into it, for about half the cost of replacing the line. There are important environmental advantages to this method, too. Denis Du Bois interviews Glen Bertini, CEO of Novinium. (podcast)
