Revamping existing buildings to make them energy efficient

http://m.phys.org/news/2014-03-revamping-energy-efficient.html

” The EU-funded BRICKER project aims to develop ways of reducing energy consumption by 50% in existing buildings, within the next four years.”

That is pretty aggressive.  Most buildings in NYC who enroll in the NYSERDA MPP program struggle to meet 20% savings with an sir of 1.0

  “Passive technologies include new aerating windows, with an integrated, newly patented electronic heat exchanger, new PIR (PolyIsocyanurate)-based insulation foams with embedded phase-change materials (PCM’s)— which are substances capable of storing and releasing large amounts of energy—and state of the art ventilated facades, commercial windows and insulation panels.”

What is the payback on these technologies?  Are they readily available in the US?

Can the US implement a similar program?

A Deeper look into the impacts of clean tech on Germany

“The web is littered with conflicting opinion pieces on the German experience — some claiming the country’s aggressive promotion of renewables is anoncoming economic disaster, and some saying those concerns are far overblown, if not totally false. So what are we to believe?

In this week’s show, we’ll look at Germany’s evolving relationship with renewables, the impact on electricity prices, and the outlook for its nuclear phase-out.” — The ENERGY GANG

Exploring the Future of Wind and Hydrokinetic Energy

Hydrokinetic power is attractive due to its abundance, particularly near population centers. It is estimated that 370 TWh/yr (terawatt-hours per year) of hydrokinetic power is available from rivers and tidal currents in the United States, which equates to about 9% of the total annual U.S. energy demand. An additional 1,170 TWh/yr (29% of US energy demand) is available from wave power “–Q&A with Dartmouth’s Brenden Epps

Owens Corning, NYSERDA And Constellation Power Up Largest Solar Installation Under NY-Sun Initiative

“The solar power system is composed of approximately 9,000 ground-mounted, photovoltaic panels located on more than nine acres. The system is expected to generate approximately 3.3 million kilowatt-hours of electricity per year (based on first year production). Generating the same amount of electricity using nonrenewable sources would result in the release of approximately 2,339 metric tons of carbon dioxide, or the equivalent emissions from 487 passenger vehicles annually, according to U.S. Environmental Protection Agency data for the region.”– NYSERDA
