Whitest paint ever created could have air-con like cooling effects

"...The materials we coat our buildings with can have a big influence on their ability to reflect heat from the Sun and overall energy efficiency. Engineers at Purdue University have been at the cutting edge of this field of research for some time, and have just produced the whitest paint ever created, which they say reflects 98. 1 percent of sunlight and can produce cooling effects that are on par with common air conditioners..."

Launching a new report on transforming home energy retrofit programs across British Columbia

"...Our newest report now turns to the topic of income-qualified energy efficiency programs, in particular, the Energy Conservation Assistance Program (ECAP) administered by utilities including BC Hydro and FortisBC, through a lens of equity-based program design. We considered the customer experience in depth, including a process of “journey mapping” the path of a participant through all stages of ECAP. Our research also looked at better practices and program examples from several other jurisdictions including Ontario, Nova Scotia, California, and Vermont..."

Designing selective membranes for batteries using a drug discovery toolbox

"...Now, as reported today in the journal Nature, researchers have designed a polymer membrane with molecular cages built into its pores that hold positively charged ions from a lithium salt. These cages, called "solvation cages," comprise molecules that together act as a solvent surrounding each lithium ion - much like how water molecules surround each positively charged sodium ion in the familiar process of table salt dissolving in liquid water. The team, led by researchers at the U..."

Low-cost technology reduces the cost and carbon footprint of pressurized irrigation

"...With the aim of increasing the energy efficiency of irrigation, researchers at the Hydraulics and Irrigation Group with the María de Maeztu Unit of Excellence,at the Department of Agronomy of the University of Cordoba (DAUCO), Juan Antonio Rodríguez Díaz and Jorge García Morillo, have field-tested a low-cost technology that takes advantage of the excess pressure on the grid to generate energy. This technology has made it possible, on the farm where it was installed, to forego the diesel generator that was used to power filtering equipment, fertilizer injector pumps and other devices necessary for irrigation, rendering the gridself-sufficient and operating on clean energy. The annual savings for the farmer came to €2,400, and his carbon footprint was reduced by up to 9 tons of CO2 thanks to the complete elimination of the diesel generator..."

What is building as a system, and why is it important? ECO Canada

"...Before the introduction of the systems approach, building components and parts were looked at in isolation[2]. This led to issues with buildings becoming too hot, too cold, having high condensation levels, noise complaints from occupants or flooding where the building’s connection to municipal sewage systems was not taken into consideration[3]..."

BLOG: Despite court ruling, Ottawa’s carbon tax remains fundamentally flawed

"...In a highly anticipated announcement, the Supreme Court of Canada today ruled that the federal carbon tax is constitutional. This decision allows the federal government to push ahead with its ambitious plan to ensure every province and territory has a price on carbon to reduce greenhouse gas (GHG) emissions. Leaving constitutional law aside, it’s worth reminding Canadians that the federal carbon tax still has several design flaws, which unnecessarily damage the economy..."
