Laboratories for the 21st Century: Best Practices; Energy Recovery in Laboratory Facilities (Brochure)

Description: This guide regarding energy recovery is one in a series on best practices for laboratories. It was produced by Laboratories for the 21st Century ('Labs 21'), a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. Laboratories typically require 100% outside air for ventilation at higher rates than other commercial buildings. Minimum ventilation is typically provided at air change per hour (ACH) rates in accordance with codes and adopted design standards including Occupational Safety and Health Administration (OSHA) Standard 1910.1450 (4 to 12 ACH - non-mandatory) or the 2011 American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Applications Handbook, Chapter 16 - Laboratories (6 to 12 ACH). While OSHA states this minimum ventilation rate 'should not be relied on for protection from toxic substances released into the laboratory' it specifically indicates that it is intended to 'provide a source of air for breathing and for input to local ventilation devices (e.g., chemical fume hoods or exhausted bio-safety cabinets), to ensure that laboratory air is continually replaced preventing the increase of air concentrations of toxic substances during the working day, direct air flow into the laboratory from non-laboratory areas and out to the exterior of the building.' The heating and cooling energy needed to condition and move this outside air can be 5 to 10 times greater than the amount of energy used in most office buildings. In addition, when the required ventilation rate exceeds the airflow needed to meet the cooling load in low-load laboratories, additional heating energy may be expended to reheat dehumidified supply air from the supply air condition to prevent over cooling. In addition to these low-load laboratories, reheat may also be required in adjacent spaces such as corridors that provide makeup air to replace air being pulled into negative-pressure ...

Technical Assistance Guide: Working with DOE National Laboratories (Brochure)

Description: A fact sheet that provides an overview of FEMP's technical assistance through the Department of Energy's National Laboratories. The Federal Energy Management Program (FEMP) facilitates the Federal Government's implementation of sound, cost-effective energy management and investment practices to enhance the nation's energy security and environmental stewardship. To advance that mission, FEMP fosters collaboration between Federal agencies and U.S. Department of Energy (DOE) national laboratories. This guide outlines technical assistance capabilities and expertise at DOE national laboratories. Any laboratory assistance must be in accordance with Federal Acquisition Regulation (FAR) Subpart 35.017 requirements and the laboratory's designation as Federal Funded Research and Development Center (FFRDC) facilities.

Greening of the White House: Six year report

Description: The White House, which recently celebrated its 200th birthday, has a long tradition of demonstrating technological innovation. In keeping with that tradition, President Clinton announced the Greening of the White House Initiative on Earth Day 1993. The initiative improves the energy and environmental performance of the White House complex by identifying opportunities to reduce waste, lower energy use, and make an appropriate use of renewable resources, all while improving indoor air quality and building comfort. This report on President Clinton's legacy of greening at the White House summarizes progress made to date and gives an overview of new opportunities identified during the past year. It also includes an environmental history of the White House and a short tour of the buildings that make up the White House complex. Over the past five years, this initiative has involved hundreds of dedicated people from both within and outside government. A description of how they worked together to develop and implement the Greening Plan is also included in this report.

Thermal energy storage for space cooling. Technology for reducing on-peak electricity demand and cost

Description: Cool storage technology can be used to significantly reduce energy costs by allowing energy intensive, electrically driven cooling equipment to be predominantly operated during off-peak hours when electricity rates are lower. In addition, some system configurations may result in lower first costs and/or lower operating costs. Cool storage systems of one type or another could potentially be cost-effectively applied in most buildings with a space cooling system. A survey of approximately 25 manufacturers providing cool storage systems or components identified several thousand current installations, but less than 1% of these were at Federal facilities. With the Federal sector representing nearly 4% of commercial building floor space and 5% of commercial building energy use, Federal utilization would appear to be lagging. Although current applications are relatively few, the estimated potential annual savings from using cool storage in the Federal sector is $50 million. There are many different types of cool storage systems representing different combinations of storage media, charging mechanisms, and discharging mechanisms. The basic media options are water, ice, and eutectic salts. Ice systems can be further broken down into ice harvesting, ice-on-coil, ice slurry, and encapsulated ice options. Ice-on-coil systems may be internal melt or external melt and may be charged and discharged with refrigerant or a single-phase coolant (typically a water/glycol mixture). Independent of the technology choice, cool storage systems can be designed to provide full storage or partial storage, with load-leveling and demand-limiting options for partial storage. Finally, storage systems can be operated on a chiller-priority or storage priority basis whenever the cooling load is less than the design conditions. The first section describes the basic types of cool storage technologies and cooling system integration options. The next three sections define the savings potential in the Federal sector, present application advice, and describe the performance experience of ...

Distributed Energy Resources at Naval Base Ventura County Building 1512: A Sensitivity Analysis

Description: This report is the second of a two-part study by BerkeleyLab of a DER (distributed energy resources) system at Navy Base VenturaCounty (NBVC). First, a preliminary assessment ofthe cost effectivenessof distributed energy resources at Naval Base Ventura County (NBVC)Building 1512 was conducted in response to the base s request for designassistance to the Federal Energy Management Program (Bailey and Marnay,2004). That report contains a detailed description of the site and theDER-CAM (Consumer Adoption Model) parameters used. This second reportcontains sensitivity analyses of key parameters in the DER system modelof Building 1512 at NBVC and additionally considers the potential forabsorption-powered refrigeration.The prior analysis found that under thecurrent tariffs, and given assumptions about the performance andstructure of building energy loads and available generating technologycharacteristics, installing a 600 kW DER system with absorption coolingand recovery heat capabilities could deliver cost savings of about 14percent, worth $55,000 per year. However, under current conditions, thisstudy also suggested that significant savings could be obtained ifBuilding 1512 changed from its current direct access contract to a SCETOU-8 (Southern California Edison time of use tariff number 8) ratewithout installing a DER system. Evaluated on this tariff, the potentialsavings from installation of a DER system would be about 4 percent of thetotal bill, or $16,000 per year.
