With Congress and the Administration still plotting their next moves in the wake of the federal courts’ vacating of SNAP rules 20 and 21, many states are pledging to regulate HFCs themselves. And while the risks of this approach, particularly the fracturing of the U.S. HVAC market, have been well documented, one aspect remains relatively
In order for the world to meet the climate goals of limiting global warming temperature rise to no more than 2oC, we will need to make a significant investment in energy efficiency and renewable forms of energy. On the other hand, the cost of doing nothing would likely run into the many trillions of dollars
The dialogue on buildings and energy is quickly shifting. Not that many years ago the focus was on the push for more efficient equipment—an HVAC unit with a higher SEER. Then came the recognition that such progress had both practical limits and limits written into the laws of physics. Attention began to shift to systems thinking—how
Currently, 282 cities have signed on to the ‘We Are Still In’ Group, and in support, the C40 Cities initiative (now actually 94 cities around the globe) and American Cities Climate Challenge are just two of the organizations that provide for cities to share best practices. Among those best practices are energy benchmarking and disclosure
If you’ve been in facility management long enough, you’ve encountered a few of these problems before: variable speed pumps that run close to 100% much of the time; a chiller that labors with low Delta T; or, worst of all, complaints of hot and cold spots in occupied spaces. So, what do you do? Look
One of the barriers to the new refrigerants is the recognition of flammable refrigerants in building codes. Codes dictate so much about building construction and what mechanical equipment can be used. There are codes for fire protection, building construction, mechanical systems, and other aspects of buildings; all affect the HVACR system. A good article on
Henry Ford once said, “You can have any color you want as long as it’s black”—a slogan that launched the early industrial model. And still today industry relies on economies of scale—and scaling means as little product differentiation as possible within a product line. Industrial efficiency thrives on product commoditization, but in a competitive global
How utility demand response works In recent years, many utilities have started offering demand response programs designed to cut electric consumption during peak times of the day when electricity is in high demand. Each program is influenced by many factors, including the transmission system, the individual utilities involved, and the technology used to trigger a
Revolutions in the science, strategies, and prospects for building performance are happening faster than transformation of the American building stock. Within a decade the frontier moved from more energy-efficient building components to integrated buildings systems, opening dramatically new opportunities. Today the focus for strategic leaders is looking toward holistic buildings within systems-integrated communities that cut
Over the next 30 years or so, the world’s population is expected to skyrocket from about 7.6 billion today to more than 9 billion — and a resounding 70% of people, the UN estimates, will live in cities. This begs the questions: How will we prepare our infrastructure to accommodate such a shift? And, how
