Shaping Tomorrow's Built Environment Today
May 23, 2024
Throughout May, more than 140 wildfires have burned across Alberta and British Columbia. As warmer temperatures and drier conditions fuel more frequent and severe wildfires, an emerging field of research is uncovering the threat of poor indoor air quality from wildfire smoke. This article investigates the ways poor indoor air quality could affect individuals—and how experts are trying to keep indoor air clean. Read more
A groundbreaking approach employing quantum physics could enhance storage capabilities in batteries, enabling them to accumulate power at a quicker pace than traditional electrochemical cells. Physicists from National Cheng Kung University have devised a new procedure that could turn the conceptual fast-charging quantum battery into a workable model. Rather than using a real battery, the experiment involved a confined ion in a superposition known as a qubit, pictured here.  Read more

The Japanese government will map out a new national strategy encompassing decarbonization and industrial policy targeting 2040 by the end of March of 2025, industry ministry officials said on Monday. The world's fifth-largest carbon dioxide (CO2) emitter aims to cut emissions by 46% from 2013 levels by 2030 and achieve net zero by 2050. The move is aimed at setting out a long-term strategy to encourage investment to accelerate decarbonization and to bolster the competitiveness of domestic industries. Read more
Progression of Energy Efficiency Regulations on Fans
Join Journal Managing Editor Kelly Barraza and guests Christian Taber and Michael Ivanovich as they discuss how the fans and blowers industry has evolved in recent years. Key talking points will include the progression of energy efficiency regulations on fans, ASHRAE Standard 90.1, large diameter ceiling and circulating fans, drives, and commercial and industrial applications of the technology.

The Federal Energy Regulatory Commission (FERC) in a 2-1 vote approved a rule aimed at facilitating a massive build-out of the U.S. electric system and directing U.S. electricity grid operators to plan new transmission infrastructure that can deliver more renewable energy and defend against extreme weather. The rule, Order 1920, stated that grid planners and transmission owners must look 20 years ahead to expected shifts in electricity production and long-term benefits to building and upgrading power lines. The FERC also established new requirements for allocating the costs of building high-voltage power lines among customers, pulling states deeper into issues around regional infrastructure. Read more
