Developing a Framework for Zero Carbon Buildings

Net zero carbon buildings are green and healthy buildings. They use energy ultra-efficiently and are supplied by renewables. They are comfortable homes where money isn’t wasted on energy bills, productive workplaces insulated from extreme temperatures, and healthy schools free from dirty air.  Action is needed today, because most buildings will be standing for generations to come. Missing this opportunity locks …

Can NY Make Buildings Super Efficient, Super Fast?

“What’s smart about this bill is it doesn’t ask for a small increase. It asks for a big increase,” says Greg Kats, president of Capital-E, a clean-energy consultancy and capital firm. “It’s the kind of thing where if you’re going to do something, you should do quite a lot of it, because the transaction costs [for landlords] to set it …

Hamburg’s Green Roads, bike paths and green space linkages

Joe Bauer, Streetfilms.org, In EUROPE/ TRAVEL  A Look at Cycling Culture in Hamburg, Germany Recently I was in Hamburg, Germany to cover their cycling scene and the car-free story that swept across the internet. Check out more at Streetfilms.org. My interest in traveling to Hamburg, Germany piqued following news early last year that the city would become car-free over the next 15 to 20 years. The distaste …

Clean energy engineering experts share blueprints for zero-emission buildings

Both new construction and retrofits can move to net-zero greenhouse gases and save money, experts report. Buildings account for nearly four-tenths of U.S. energy consumption through heating, cooling and other electricity use, according to the Energy Information Administration.  Steps like moving from T8 fluorescent bulbs to LED lighting could provide up to 35% savings, with dimming controls and occupancy sensors adding more savings. …

A quantum leap forward in air conditioning technology

A quantum leap forward in air conditioning technology.  “Refrigerators and air conditioners based on HFCs and HCs are also relatively inefficient,” said Dr. Xavier Moya of the University of Cambridge. “That’s important because refrigeration and air conditioning currently devour a fifth of the energy produced worldwide, and demand for cooling is only going up.” Eco-Friendly Solid Could Replace Conventional Refrigerants …

New York City Seeks To Reduce Carbon Emissions From Buildings By 40%

April 19th, 2019 by Steve Hanley on Clean Technica Climate advocates know that meeting the goals of the Paris climate accords means more than generating more renewable energy. It also requires reducing emissions from existing sources. At present, 67% of all greenhouse gas emissions  in New York City come from buildings, not from transportation as you might expect. On April 18, the city …

The next frontier in fighting climate change – your cooktop/kitchen stove: California is looking for ways to phase out fossil gas, not just from power plants but also from stoves, water heaters and furnaces

A recent report, the California Energy Commission described a “growing consensus that building electrification is the most viable and predictable path to zero-emission buildings.” Renewable gas, the report said, “can be a part of the solution to reducing [greenhouse gas] emissions from buildings, but the role is likely to be constrained by limitations on renewable gas availability, cost, and ongoing methane …
