A little water conservation can go a long way. And as the second-most visited space in commercial buildings — just behind the lobby — the restroom and its water-saving fixtures can help lead the way when it comes to cutting back consumption.
AWWA discusses current challenges and how its committees are working to provide solutions.
July 18, 2022
Having completed its inaugural Water Quality Matters column series focusing on the theme, “Hot Topics in Water Quality,” the AWWA Water Quality and Technology Division’s committees look to extend the conversation by responding to a common question: “What keeps your committee members up at night?”
The state of Rhode Island has very little in common with the city of Anchorage, Alaska. Both, however, have something in common with the worldwide travel destination known as French Polynesia.
The commercial water heating market has options for building owners and facility managers when it comes to selecting equipment for their facilities — tank or tankless, gas models or electric — even heat pump water heaters are seeing growth in this space. So which is the most popular? Well, it all depends on who you ask.
All hydronic systems designed around renewable energy heat sources — as well as those designed around conventional boilers — have at least one controller that measures and responds to temperature. Common examples are temperature setpoint controllers, outdoor reset controllers, mixing controllers and differential temperature controllers. Complex systems that operate in multiple modes, or use multiple heat sources, often have several temperature-based controllers.
The 7th Emerging Water Technology Symposium (EWTS) was held in San Antonio the second week of May. The Symposium is sponsored by the leading plumbing groups: IAPMO, ASPE, PMI, World Plumbing Council, and the Alliance for Water Efficiency. This two day Symposium always has some interesting presentations.
Pressure relief valves protect fire sprinkler system components by relieving excess system pressure from supply surges or temperature changes. Since the 2010 edition, NFPA 13: “Standard for the Installation of Sprinkler Systems” has required pressure relief valves to be installed on all wet pipe fire sprinkler systems.
While it may feel like the other side of the world, Russia’s invasion of Ukraine will have lasting effects — including sparking the European Union’s hasty transition to energy independence. Last month, the EU announced a $300 billion roadmap to ditch Russian energy — mainly oil and gas. The EU said it would slash consumption of Russian gas by 66% by the end of the year, and break its dependence completely by 2027 by saving energy, finding alternate sources and speeding up the transition to renewables, according to ABC News.
As global energy planning moves away from fossil fuels and toward electricity, an increasing number of hydronic heating systems are being supplied by heat pumps. Some use water-to-water heat pumps supplied by geothermal earth loops. Others use air-to-water heat pumps.
