MARKET FOCUS: DATA CENTERS
Introducing Data Center Energy Standard
|
|
|
|
Cloud adoption is expected to double the size of the data center industry during the next five years. Companies in Brazil, Russia and many other nations are aggressively building data centers for storage of new servers. ASHRAE Standard 90.4-2016 provides baseline energy efficiency requirements for data centers for design, construction, operation and maintenance, along with use of renewable energy resources. Data center applications differ from commercial building counterparts because of higher plug loads and rapidly changing technology for the IT equipment and associated power/cooling approaches. By using an approach that requires compliance to a “system” level of performance, designers and end-users can make trade-offs in their optimization strategizes depending on business models. Designers and building owners will keep this article for its important information on efficient data center technology and required performance.

College Police Substation & Parking Structure
|
|
The variable refrigerant flow systems provide HVAC for a California community college’s police substation. Condensing units are on the rooftop, with indoor fan coils located within the ceiling space. An outdoor condensing unit with multiple indoor units and premium efficiency direct-drive fans for space cooling and heating serve the common areas of the substation. The system creates an arrangement allowing for heat recovery between multiple zones and simultaneous heating and cooling for maximum efficiency. The photovoltaic system generates 35,000 kWh per year. Designers will share this article for its information on alternative energy, solar chimneys and natural ventilation.

Journal Roundtable: Mildly Flammable Refrigerants
|
|
Global climate change and protection of the earth’s ozone layer has prompted the phase-out of commonly used refrigerants such as R22. ASHRAE Journal assembled a roundtable of experts to discuss refrigerants classified by ASHRAE as A2L, or mildly flammable with low toxicity. This article will explain lessons learned from using A2L refrigerants in Europe and Japan and how humidity affects flammability. Refrigeration engineers will keep this article for its information on alternative refrigerants for air conditioning.

Using Carbon Dioxide Refrigeration Systems in Ice Rinks
|
|
Artificial ice rinks are evolving, partly related to the phase-out of refrigerants tied to global climate change. Naturally occurring refrigerants such as carbon dioxide, ammonia and hydrocarbons are refrigerants commonly considered. This article explains how transcritical carbon dioxide systems differ from traditional ice rinks in design and operation. Engineers will read this article for its guidance on refrigeration, naturally occurring refrigerants and compressors.

How to Improve Commercial Building Energy Intensity?
|
|
Singapore’s Green Mark program provides results on improving that country’s commercial building energy use. According to a report by the U.S. Department of Energy, American commercial buildings have plateaued. This article examines the Green Mark’s impact by mandating minimum verifiable system-wide operating efficiencies. Building professionals will keep this article for its data on commercial building components, along with how they interact within the whole building system.

How to Address Stack Effect for Tall Buildings
|
|
Stack effect is the movement of air through buildings resulting from air buoyancy. Problems can occur when a building is operating in cold weather. An automation system could indicate the building static pressure is slightly positive relative to the exterior while static pressure at the base of the building is negative compared to the exterior. Failure to maintain slightly positive or, at least, neutral pressurization at the base of the building will allow the infiltration of cold, unfiltered outdoor air into the building through construction gaps and exterior entryways. Building professionals will share this article for efficient ventilation by preventing unintended outdoor air infiltration.
