Plug and process loads in commercial buildings account for 5% of U.S. primary energy consumption. Minimizing these loads is a primary challenge in the design and operation of an energy-efficient building.

This presentation describes how the designers, owners, and occupants can take advantage of opportunities to reduce plug loads in the Research Support Facility.
This presentation decribes how building an energy-efficient data center can improve a business's bottom line.
The Research Support Facility complex (RSF, RSF II, parking garage, and associated site lighting) was designed to produce more on-site renewable energy than it uses over the course of a typical weather year, when accounted for at the site. To date, the end use performance monitoring and verification suggests that when the RSF complex is fully built out, we will meet the annual energy use goals. Continued performance monitoring and occupant education are required to ensure annual energy use goals will continue to be met.
This presentation highlights the importance of modeling the off-design performance of equipment in data centers as a consequence of their dynamic behavior and describes an experimentally validated tool for modeling the energy use of the data center and cooling infrastructure.
An energy-efficient data center includes targets for its power usage effectiveness (<1.2) and energy resource efficiency (< 0.9). It should be designed with hot isle–cold isle separation, use free cooling (economizer) and evaporative cooling when available, minimize fan energy, and use the most energy-efficient equipment possible.
A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.
Understand the purpose of re-tuning, definition of small and medium-sized building re-tuning, and what to expect from the re-tuning training class.
