Investing in more efficient ACs could cut future energy demand in half
Our Efficient Cooling Scenario shows that effective policies can double average AC efficiency and reduce cooling energy demand by 45% compared to the Reference Scenario.
Cooling will drive peak electricity demand, especially in hot countries
More efficient ACs can reduce the need for new power plants to meet peak power demand, especially at night.
2018/10/02: Traditionally, geothermal systems are custom made for homes. But Dandelion wanted to automate the manufacturing process and make the system work with every home.
"One thing we looked for at X was adding technology to an industry that hasn't benefited [from tech]," Hannun said. "I started working on it part-time. About two-thirds of the year in [we realized], 'There's something here. Let's focus on it.'"
The startup claims Dandelion Air is four times more efficient than furnaces, and almost twice as efficient as traditional air conditioning systems. It also comes with a Nest learning thermostat and a monitoring system to track its performance.
What is a healthy room temperature? On releasing its Cold Weather Plan for 2014, Public Health England has recently revised its recommended minimum levels to keep in good health. No longer, they say, do
The steadfast rotating fan has been employed to keep people cool since the eighteenth century, and it remains highly effective, requiring much less energy and providing more comfort than air-conditioning. Cooling people by increasing local airflow is at least ten times more energy efficient than refrigerating the air in a given space, and it also adds the benefit of a personally controlled thermal environment. If used in combination with air-conditioning, fans could lower energy use by 30-70%, even in incredibly hot climates or during heat waves. Circulating fans, which have become very energy efficient in their design, can be readily and cheaply applied in both new and existing buildings. Recent changes in international comfort standards have paved the way for...
A team of students at MIT is working on a prototype wearable that asks one important question: Why heat or cool a building when you could heat or cool a person?
