Pumps Operations in the Building Envelope

Pumps Operations in the Building Envelope

Water flows downhill. Nothing could be more simple. Getting water to the top floor of an urban skyscraper is a bit more difficult. Mere gravity flow or even accumulated static pressure head aren’t sufficient to accomplish this task. Pumps are obviously needed. But what kinds of pumps are used in

Project Profile: Winning the Battle Against High Energy Costs

Project Profile: Winning the Battle Against High Energy Costs

At a recent ceremony recognizing excellence in electrical energy savings, the Montreal-based Hydro-Québec Utility Company awarded three citations of excellence to a system designer who used Daikin water-cooled screw compressor chillers in industrial applications. The awards were impressive. But beyond accolades, the 30% annual energy cost savings achieved by one

Renewable Energy for Onsite Power Generation

Renewable Energy for Onsite Power Generation

Although every situation is unique, and it’s difficult to generalize, Barry Worthington, executive director of the US Energy Association (USEA) in Washington, DC, says progress in renewable energy over the last 10 years has been phenomenal as systems become more efficient. Nevertheless, use of renewable energy for onsite power generation
