Building On A Swedish Tradition

Reflecting a long-established Swedish commitment to environmental stewardship, the Nelson Cultural Center addition at the American Swedish Institute (ASI) in Minneapolis integrates several technically advanced sustainable features, including a high-efficiency geothermal heating and cooling system that reduces energy consumption by nearly 30 percent (based on an ASHRAE 90.1 baseline) while supporting the Institute’s diverse community programming.

Calculated Conditioning: The IAQ Of UFAD

Since their introduction in Europe in the 1950s, and their domestic rise in specification during the 1990s, UFAD and displacement ventilation systems promise significant energy savings as a direct result of a higher supply air temperature that yields an increase in the use of economizer or free cooling hours.

The Importance of MEP Coordination

Last month, I addressed the challenge faced by new construction project teams to build faster and cheaper. In the normal project delivery process, this responsibility falls on the construction manager and/or general contractor (CMGC).

The Challenges Of Federal Government Procurement

The procurement process used by the U.S. government (or its contractor) can follow one of several different paths. Usually, an equipment specification is written that contains performance criteria and other requirements. A solicitation is then released and potential sellers competitively bid for the work.

Cooling & Chillers

Chillers Past, Present and Future

We had an idea to try something different this month — invite chiller manufacturers to give us their insights on one of two topics. We invited them to either talk about common errors in project design/installation/O&M, with an eye toward helping readers get the intended performance out of their equipment. Or, they could write about what they see happening in this sector in the future. In a stroke of good luck, we had one response to each question. – Ed.)

Building Automation Evolution

There are many elements to a BAS. Of course, the ability to control systems through direct digital control (DDC) is always a require-ment, but ideally, we expect these systems to be much more.

Steam boilers help distillery with sustainability goals

Death’s Door Spirits in Middleton, WI, is a popular craft distiller known for its vodka, gin, and whisky that uses organic wheat from Washington Island, Wis. The brand is sold across the United States and Europe, and according to the distillery, the beverages would not be possible without the use of two LX-100 SG steam boilers from Miura.
