LEED recognizes Living Building Challenge credits

LEED to Recognize Living Building Challenge Credits

The U.S. Green Building Council recently announced that it will recognize energy and water requirements from the Living Building Challenge (the Challenge) green building system within the LEED green building program. Projects achieving the energy and water requirements in Living Building Challenge will be considered as technically equivalent to LEED. “USGBC and the International Living Future Institute, developers of the Living Building Challenge, share a common commitment and goal to transform the way we design, build and operate our buildings,”…

Eiffel Tower Goes Green

An ambitious remodel project at the Eiffel Tower is making its operations greener. The first floor of the landmark building was recently refurbished for a better visitor experience and to improve the environmental impact of the historic building. First floor glazing was changed to provide a 25% reduction in solar heat gain during the summer months. This will significantly reduce the need for air conditioning, saving money and energy. Almost all of the lighting in the first floor was changed…

Wind Tree Provides Silent Wind Power Beautifully

A new French start-up, NewWind, is making wind power beautiful! Their new Wind Tree offers almost a hundred mini-windmills on an apparatus designed to look like a tree. Due to the light construction of the “leaves,” the Wind Tree generates power at wind speeds as low as 4.4 miles per hour! This translates into sustained operation times (an average of 320 days a year) that are almost double those of standard windmills that need higher wind speeds in order to…

Author John Perlin and The Solar Cell

In a discussion today about solar energy and the coming Year of Light, author John Perlin helped enlighten me about the importance of the solar cell (photovoltaic systems) as a source for renewable electricity. What is the biggest consideration in designing a PV system, as opposed to a solar thermal system that uses multiple heliostats?   The answer: PV functions without requiring moving parts. Perlin, author of Let It Shine: The 6,000-Year History of Solar Energy, elaborates on that answer,…

Hybrid Solar Cell Is Also A Battery

Solar cells are great. They provide us with clean, renewable energy for free. As long as the sun is shining, that is. For decades, critics of solar power have taunted that electricity generated from fossil fuels is better because it is available any time of the day or night. But what if there was a solar cell that is also a battery and could store the electricity it makes for later use? In an article published by Ohio State University this…

Home Energy Storage Market to Grow 1000% by 2018

  Market research firm IHS says home energy storage will explode from 90 megawatts this year to over 900 megawatts by 2018. That’s a growth rate of 1000% – a staggering increase, if true. What’s driving this trend toward more in-home energy storage? IHS says its all about rapidly falling costs. The vast majority of people with solar arrays on their rooftops today are using the electrical grid as their storage medium. Any excess electricity they generate during the day is sold to…

Soccer Field Lights Powered By Players’ Energy

In a Brazilian neighborhood plagued by blackouts, panels under the turf of a neighborhood soccer field, fueled by players running over them, provide electricity to light the field and the surrounding homes. A typical soccer player can run up to seven miles during a football game. Most of the players in this neighborhood are local children, poor, who formed a very attentive audience while the field was being installed. The panels provide clean, human powered energy to a neighborhood that…

Links Leading to Today’s Solar Revolution

This miniseries on the solar revolution is based on John Perlin’s Book, Let It Shine: The Story 6000-Year of Solar Energy. We commence with the discovery of photosensitivity. Read this , then read his excellent book. Part 1 – The Discovery of the Photosensitivity of Selenium When my book, Let It Shine: The Story 6000-Year of Solar Energy, first came out several experts criticized me for not recognizing Edmund Becquerel as the direct link to the solar cells in use today. When…

What is LEED? – Energy and Atmosphere

This is the fifth post in a series on the LEED green building rating system. The first post provided an Introduction to LEED, the second looked at the Sustainable Sites credit category, the third at the Location and Transportation credits, and the fourth at Water Efficiency.   Energy and Atmosphere Improving energy efficiency is one of the easiest ways to save money and improve the sustainability of a building. Therefore almost a third of the points available in LEED are found…

Water and Sunlight the Formula for Sustainable Fuel

This news on water and sunlight from Australian National University is worth reading. An Australian National University (ANU) team has successfully replicated one of the crucial steps in photosynthesis, opening the way for biological systems powered by sunlight which could manufacture hydrogen as a fuel. “Water is abundant and so is sunlight. It is an exciting prospect to use them to create hydrogen, and do it cheaply and safely,” said Dr Kastoori Hingorani, from the ARC Centre of Excellence for…

Composite Material Reduces Cost of Solar Panels

Yingli Green Energy, the largest vertically integrated photovoltaic module manufacturer in the world, known as “Yingli Solar,” announced that they have successfully completed trial production of monocrystalline ingots for solar panels using new material technology. Instead of using traditional graphite crucibles when pulling monocrystalline ingots, Yingli experimented with crucibles made from a carbon-carbon (C-C) composite material. Yingli’s initial estimates suggest that the new material could reduce manufacturing costs for solar panels by nearly 0.01 USD per watt. CivicSolar defines monocrystalline silicon as…
