Staying Dry & Comfortable With Liquid Desiccants

Let a scientist with experience both at the National Renewable Energy Laboratory and on the manufacturer side discuss the possibilities of a newer dehumidification technology within the framework of the same old moisture challenges.
In the summer, conventional air-conditioning systems in buildings are challenged to meet peak humidity loads. Over time, buildings have reduced their heat (sensible) load, but have done less to reduce their moisture (latent) load. As a result, this moisture load can become too large for conventional air-conditioning systems to handle.

Building On A Swedish Tradition

The American Swedish Institute looked homeward to plan for its future, using geothermal technology to achieve high-performance energy solutions in an urban setting.
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.

Chillers Best Practices: Past, Present and Future

A couple of industry pros weigh in on how past ‘best practices’ sometimes get in the way of current potential, and on where technology might point.
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.)

Calculated Conditioning: The IAQ Of UFAD

UFAD and displacement ventilation systems require accurate estimates to meet relative humidity requirements and ensure efficient operations. Take a look at a few design options, and contemplate the reader challenge at the end.
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 Heat Is On But The CRACs Are Off... Now What?

With Hurricane Sandy fresh in our minds, let’s examine the anatomy of a recent outage’s immediate HVAC consequences as a guide toward protecting equipment in the future.
October 29 was a Monday. It was also the day that Hurricane Sandy made landfall in New York City. Around 7 p.m., Con Edison shut power off in Lower Manhattan, and it would be sometime Saturday before lights would begin to flicker back on.

Sustainable Schools: Teaching By Example

See how Charlotte-Mecklenburg Schools weathered an economic downturn through efficiency, managing to use less energy while adding facilities.
Providing high-quality education for our nation’s children in grades K-12 has never been more important than it is today. The world is changing fast, and we need to provide an educational system that prepares them for this fast paced world in which we live.

Ventilation To Improve IAQ In Schools

The author heads to the blackboard to break down fundamental outside air and sensor strategies (and how they can work together).

Corps Community Revival: New Chicago Community Center Features Diverse MEP Design

Practical MEP design — comprising modular boilers, waste heat recovery, remote monitoring, designing around local restrictions, and much more — delivers flexibility and sustainability to Chicago’s largest community center.
In today’s world, so-called “high-performance, sustainable” facilities are a dime a dozen. But many of these buildings rely on overly complex mechanical systems to carry out their mission.
