Buildings eat up a huge amount of energy—about two-fifths of the country’s total use—so to suppress their appetite for power, efficiency entrepreneurs are churning out a suite of nifty technologies, like automatically shading windows, smarter thermostats, and high-tech heating and cooling systems. But a new report from the National Trust for Historic Preservation’s Preservation Green Lab concludes that constructing new, energy-efficient buildings almost never saves as much energy as renovating old ones. Renovated buildings outperformed new buildings on energy savings in every category: single-family homes, multifamily complexes, commercial offices, “urban village” mixed-use structures, and elementary schools. Though the conclusion may seem counterintuitive in an age of ambitious LEED standards in many new buildings, consider that it uses more energy and creates more impact to construct an entirely new building than to fix up one of the same size for the same purpose.

This graphic shows color-coded simulation results from advanced computational models used to characterize the properties of materials used in organic photovoltaic solar cells in efforts to better understand the physics involved and to improve the technology. The new Network for Photovoltaic Technology research center led by Purdue University and funded by the Semiconductor Research Corporation, aims to develop such computational capabilities for broad range of PV technologies for higher efficiency and reduced manufacture cost.

Data to be a defining tech trend in 2012
Dec 24, Technology/Hi Tech & Innovation The start of this year was marked by a tech industry obsession with where to put growing mountains of information gathered online and by sensors increasingly woven into modern lifestyles. External drives boasted seemingly unfillable capacities and companies touted services for storing bits and bytes at massive data centers in the Internet "cloud." As 2012 approaches, focus has turned to searching for trends, patterns and other useful insights about people's preferences and behaviors that might be buried in troves of data. "Big analytics toward the end of the year became the big term and into next year it will be the big term," independent Silicon Valley analyst Rob Enderle told AFP on Friday.5 Steps To Measure The ROI Of Digital Media Channels
Many marketers have worked hard in 2011 to develop appropriately customized ROI measures for social media. I have dedicated a few previous posts on how to approach these measures. As we move into 2012, I would like to raise a key question of measurement that isn’t consistently addressed but is of critical importance. That is: How are you measuring the interplay and overall performance of your combined paid, earned, and owned digital media channels?Bio Energy
