Mass-production techniques + aggregated demand among building owners to cost-effectively retrofit buildings to a net-zero energy standard

The Challenge of Scaling Up Energy Retrofits for Buildings Most building energy retrofits are one-off affairs. “We need an Amazon” in the market, says one architect. By Tom Konrad, GTM, July 19, 2019 Getting to the root of the problem.8 It’s almost always easier and cheaper to build an energy-efficient building in the first place than retrofitting existing structures. But …

Getting the Facts Right: Clean, Electric Buildings Can Reduce Greenhouse Gas Emissions AND Save Money in New Construction

Building decarbonization is a necessary component of our overall climate change strategy. Multiple analyses have shown that for new construction it is cheaper to build all-electric than to install gas-fired appliances and air conditioning. RMI found this to be true for all new construction scenarios, even without considering the gas infrastructure costs of new service lines. In all but the most coal-heavy …

Hawaii to combat climate change with carbon-injected concrete

Produced by Island Ready-Mix Concrete using waste carbon dioxide from Hawaii Gas, the carbon dioxide is mixed into the concrete using CarbonCure technology. The resulting product traps carbon dioxide in mineral form within the concrete and improves the comprehensive strength of the material Jason Plautz@Jason_Plautz, July 8, 2019 The Hawaii Department of Transportation (DOT) plans to use carbon-injected concrete in …

40% of U.S. homes were built before 1970 and reducing emissions in the building sector is 40% more cost-effective than investing elsewhere

By Mirella Vitale, SVP of Group Marketing, Communications & Public Affairs at ROCKWOOL GroupMarch 18, 2019 ROCKWOOL: Energy efficiency is the best way to create resilient cities and communities. We’re at an inflection point in the battle against climate change. With each passing day, the time available to address climate change dwindles while the effects of global climate disruption become …

Researchers In Switzerland Say Zero Emission Society Will Require Seasonal Energy Storage

July 9th, 2019 by Steve Hanley on Clean Technica.com, Researchers In Switzerland Say Zero Emission Society Will Require Seasonal Energy Storage Researchers Martin Rüdisüli, Sinan Teske, and Urs Elber of the Swiss Federal Laboratories for Materials Science and Technology (EMPA) have studied what will be needed to make Switzerland able to use only zero carbon energy. Among their main conclusions is that the …

MIT Aerogel Generates Passive Heat From Sunlight

July 8th, 2019 by Steve Hanley  It’s below freezing on a rooftop in Cambridge, Massachusetts, but inside a device created by researchers at MIT, the temperature is 220º C. There are no moving parts, compressors, or vacuum pumps involved. Just sunlight and a special aerogel it has taken researchers at MIT 4 years to perfect, aided by grants from the Department of …

Nebraska tribe’s latest energy project: reclaimed solar thermal heaters

In addition to this Nebraska example, solar thermal heating technology is alive and well in Minnesota, where the Rural Renewable Energy Alliance (RREAL) designed its own heater and for years manufactured and installed them at no cost to low-income households. RREAL has shifted its focus to community solar and licensed the design to the White Earth Nation in northwest Minnesota. The tribe …

Green New Deal is a Model for Worker Power. The 108th Int’l Labor Conference Recognizes Co-ops as ‘Future of Work’. Co-ops building affordable housing on Pine Ridge.

The Green New Deal is More Than a Climate Plan, It’s a Model for Building Worker Power. At the heart of the Green New Deal is a recognition that shifting to clean energy could leave many behind. That’s why the plan protects workers’ right to organize, calls for universal health care, retirement security and union jobs at a living wage. …

Should Electrification Strategy Emphasize Heating Over EVs?

The U.K. government is backing electric vehicles more vigorously than hybrid heat pumps. Is that the wrong approach? By JASON DEIGN JULY 05, 2019, GreenTechMedia 14 Hybrid heat pumps (HHPs) can use gas as well as electricity The focus of much attention… Moves to foster electric-vehicle adoption for energy system decarbonization in the U.K. could risk shifting the emphasis away from …
