Standard comfort measurements used to design heating and cooling systems share a common flaw, according to new research. The researchers said the error was caused by the standard instrument used to measure thermal effects of radiant heating and cooling. The instrument and associated formulas used to calculate comfort based on the sensor's readings do not properly account for air flow called free convection. The failure led to temperature errors of over two degrees Celsius.
Using 30 years of satellite data, UW researchers discovered that within one year of the opening of a major dam in the Mekong River basin, downstream river temperatures during the dry season dropped by up to 3.6 degrees F (2 degrees C).
Researchers at the University of Technology Sydney (UTS) have developed a cost-effective and practical method to protect pipelines and keep them operating during significant fault rupture incidents and large ground movements.
Academics at UCL have identified 18 reasons why megaprojects such as HS2 and Crossrail often fail, as well as 54 preventative solutions. For the first time, academics developed a systematic literature review of the causes and cures of poor megaproject performance. They identified six key themes and looked at areas where a project might fail, analysing the problems and solutions. The study was published in Project Management Journal.
Researchers have developed a new method that could one day replace conventional pressure treating as a way to make lumber not only fungal-resistant but also nearly impervious to water -- and more thermally insulating.
Economists and business leaders agree that innovation is a major force behind economic growth, but many disagree on what is the best way to encourage workers to produce the 'think-outside-of-the-box' ideas that create newer and better products and services. New research from the University of California San Diego indicates that competitive 'winner-takes-all' pay structures are most effective in getting the creative juices flowing that help fuel economic growth.
During a typical Canadian winter, snow accumulation and melt--combined with sudden rainfalls--can lead to bottlenecks in storm drains that can cause flooding. With that in mind, researchers at UBC's Okanagan campus have been examining urban stormwater drainage systems, and they too have concerns about the resilience of many urban drainage systems
Alexander County sits near the confluence of the Mississippi and Ohio Rivers, at the southernmost tip of Illinois. The sparsely populated jurisdiction is perhaps best known for devastating floods resulting from repeated failures of the Len Small levee in 1993, 2011, and 2016. Homes and businesses have been severely damaged, residents stranded, and rich agricultural land irreversibly degraded by sand deposition and erosion.
Can buildings learn to save all by themselves? Empa researchers think so. In their experiments, they fed a new self-learning heating control system with temperature data from the previous year and the current weather forecast. The 'smart' control system was then able to assess the building's behavior and act with good anticipation. The result: greater comfort, lower energy costs.
The materials the United States and other countries plan to use to store high level nuclear waste will likely degrade faster than anyone previously knew, because of the way those materials interact, new research shows. The findings, published today in the journal Nature Materials, show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
