This Fact Sheet provides an overview of the Better Buildings Workforce Guidelines project. The Department of Energy (DOE) and the National Institute of Building Sciences (NIBS) are working with industry stakeholders to develop voluntary national guidelines that will improve the quality and consistency of commercial building workforce training and certification programs for five key energy-related jobs.
While the availability of “big data” about building energy performance is increasing in response to market demands and public policies, the lack of standard data formats is a significant ongoing barrier to its full utilization. To overcome this barrier, the U.S. Department of Energy (DOE) and Lawrence Berkeley National Laboratory (LBNL) developed the Building Energy Data Exchange Specification (BEDES).
BEDES is designed to enable the exchange, comparison, and combination of empirical information by providing common terms and definitions for data about commercial and residential building’s physical and operational characteristics, energy use, and efficiency measures.
This paper describes the BEDES development process, scope, structure, and plans for implementation and ongoing updates.
Case study on Hannaford Supermarkets’ use case controllers with EEVs for their refrigeration display cases, resulting in 15-30 percent energy savings.
Case study on how CKE, in collaboration with Southern California Edison’s (SCE) New Products Development and Launch (NPDL) organization, field tested an advanced demand defrost control system for walk-in coolers and freezers in their Carl’s Jr. restaurants.
The purpose of the service hot water recovery calculator is to provide a tool for a refrigeration designer to use in estimating the potential energy savings of capturing heat from a refrigeration system for use in pre-heating a domestic hot water system. This tool assumes that only the superheated vapor portion of the refrigeration system's total heat of rejection will be captured with a heat recovery tank. Tank-type heat reclaim systems are one of the most common methods of heat recovery due to both their cost effectiveness and that large volumes of hot water are often consumed in supermarkets on a daily basis. This spreadsheet is intended for use by refrigeration or mechanical designers for rapid yet robust calculation of energy performance. This calculator assumes that the refrigeration input of the hot water recovery tank operates in series between the refrigeration compressor rack and condenser to capture superheat from compressors prior to condensing. This calculator also assumes that the domestic cold water supply is the only input to the hot water recovery tank and that hot water recirculation is not present or is returned to the service hot water system after the hot water recovery tank.
This spreadsheet is designed for use with the Refrigeration Playbook: Heat Reclaim report (www.nrel.gov/docs/fy15osti/63786.pdf). Please note that this calculator is not currently approved for use on Mac computers.
Find the presentation for the June 3, 2015 webinar on the 50% Advanced Energy Design Guide for Grocery Stores below.
The guide shows practical ways for grocery stores to achieve a 50% energy savings over ASHRAE 90.1-2004 and exceeds the requirements of 90.1-2013. Intended for grocery stores owners and designers, the guide includes specialty sections for refrigeration and food service found, not only in grocery stores but in convenience stores and food service establishments as well.
Speakers highlighted the guide, providing practical how-to tips to achieve the 50% savings level. The guide also helps those who build or design retail stores that may include refrigeration.
Below are the speakers from the webinar.
-Michael Lane, Puget Sound Energy
-Merle McBride, Owens Corning
-Caleb Nelson, CTA Group
