A recast of a presentation done for the Fairfax Chapter of Association of Energy Engineers in November of 2013. Presentation focuses on the the Advanced Energy Design Guides published by ASHRAE with association of AIA, USGBC, and IES with funding and technical support from DOE, NREL, and PNNL. In addition, the DOE Advanced Retrofit Guides are also discussed. Both sets of guides are available for download from this resource database.

The Advanced Energy Design Guide for Grocery Stores (AEDG-Grocery) is intended to provide a simple approach for contractors, designers, and owners to achieve 50% savings in grocery stores and other like retail that has refrigeration systems. Application of the recommendations in the Guide should result in grocery stores with 50% energy savings when compared to those same stores designed to the minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004. Energy Standard for Buildings Except Low-Rise Residential Buildings.
NorthBay VacaValley Hospital completed lighting retrofits to their 150,000 square foot parking lot and its 225 parking spaces. They did so with help from The California Lighting Technology Center (CLTC) at the University of California, Davis. The project has achieved 65% savings and received a 2014 Lighting Energy Efficiency in Parking (LEEP) Campaign’s award for best use of lighting controls. In addition, the retrofits improved lighting maintenance operations and end-user satisfaction.
The lighting retrofit included replacing roughly 50 induction luminaires with new LED fixtures with embedded lighting controls.
The new LED fixtures were coupled with various kinds of lighting control systems, including a radio frequency (RF) connectivity control system that was installed in dedicated zones with passive- infrared (PIR) and long-range microwave sensors to achieve energy savings. An “ultra-smart” lighting control network was also put in place, giving facility managers the ability to adjust lighting schedules, light levels and time-out settings, monitor the system’s energy use, and receive automated alerts when luminaires require maintenance.
This guide covers each major step in procuring a solar photovoltaic (PV) system:
- Conducting technical and financial studies
- Financing a PV system
- Project execution
- Operations and maintenance
- Assessing benefits
The guide provides information on the basic steps, key considerations, and where to go for more information. It is intended to provide an overview and some level of detail, with pointers to highly detailed information and resources.
This fact sheet summarizes recommendations for designing elementary, middle, and high school buildings that will result in 50% less energy use than conventional new schools built to minimum code requirements. The recommendations are drawn from the Advanced Energy Design Guide for K-12 School Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use school buildings.
Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller schools with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed an easily replicable combination of measures to achieve 50% savings in K-12 schools.
"This paper discusses the evidence regarding daylighting and student performance and development, and presents four case studies of schools that have cost effectively implemented daylighting into their buildings."
"Improved lighting efficiency has long been a major strategy to reduce the energy use in buildings. These savings have traditionally come from improved efficiency of lamps and ballasts. Today, deep energy reductions and Zero Net Energy (ZNE) are possible by continually controlling each of these efficient fixtures in response to varying details within the space. This guide provides an overview of luminaire-level lighting control (LLLC). The full LLLC approach provides controllability at each fixture with real-time energy tracking and data collection."
How to determine the amount of continuous insulation required by codes, while still retarding water vapor according to climate zone locations
"While ASHRAE 90.1 has been pushing continuous insulation (CI) for the past decade, the building codes are catching on. And now that the U.S. Department of Energy (DoE) has mandated all states to adopt a commercial building energy code that meets or exceeds ASHRAE Standard 90.1-2010, CI specifications are really being cast into the spotlight."
A detailed two page case study on the Zero Energy Ready Turkey Foot Middle School.
"Turkey Foot is revolutionizing the way kids learn, all within a new building that uses half the energy of the previous school despite being twice the size. Turkey Foot leveraged the practices and experience on other high performance goals in the District."
