Drew Turner, Global Marketing Manager for Oil-free Solutions at Danfoss, joins host John Sheff in this episode of the Envisioneering Exchange podcast for a dialogue about heat pump and oil-free technologies, their benefits and advantages (especially compared to traditional boiler-based systems), and their roles in district heating systems.
Central to the life and operation of any community is its infrastructure. From its roads and other transportation platforms to its sewers and waste treatment facilities, and from its telecommunications and power generation and distribution networks to its building stock, a community’s infrastructure not only defines its quality of life in the moment, but also
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
It is inevitable that the growth of HFC (hydrofluorocarbon) use in industrial countries will soon level off and take a downward turn. Global climate predictions — and indeed, even current climate events — are growing ever more dire, which will increase pressure to reduce the emissions of greenhouse gasses of all types. In a sign
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
In our last post, we looked at the potential for resilient infrastructure and began to consider how stakeholders of high-performance buildings have a strong hand in shaping such a future. The effort to generate support for investment in energy efficiency on the scale required for genuine resilience is, at best, a work in progress. And
In a 2015 article, the Center for American Progress (CAP) noted that resilience today is tied to new causes and consequences: “In 2013, the American Society of Civil Engineers gave America’s infrastructure a D+ rating and recommended increasing investment in infrastructure designed to ‘withstand both natural and man-made hazards.’” Simultaneously, the CAP reported that “the
If the United States is to maintain its dominance in technology innovation, we will need to continue to successfully compete in global markets. It’s as true for HVACR as for any high-tech industry; it means that we must be prepared to play by the same set of rules so that our products meet international norms.
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
