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.

This document lists a set of resources that can help small business owners make informed decisions about their energy use and identify opportunities for long-term financial savings from energy efficiency improvements. These resources include case studies, energy savings and investment calculators, technical guides and information on state and federal incentives programs.
Argonne’s Energy Efficiency Decision Support Calculator is a simple tool that small business owners can use to quickly analyze the high-level economic impact of investments in energy efficient products, retrofits or capital improvements. This tool requires minimal input data and is accessible to anyone, regardless of their experience with energy issues. It is intended to complement many of the more involved, technology specific calculators that are referenced in Argonne’s “Resources for Informed Small Business Energy Efficiency Decision Making.”
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.
"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."
"Zero Net Energy (ZNE) is the future, and in a growing number of places the present, of building design and energy policy. A growing strategy to get to ZNE is to separate the building’s heating/cooling from the ventilation/dehumidification. Design firms and owners are striving to meet heating, ventilation and air-conditioning (HVAC) loads with optimum comfort and minimal energy. Radiant systems can provide heating and cooling through pipes while ventilation and any humidity control requirements are efficiently met by a Dedicated Outdoor Air System (DOAS). This guide provides an overview of Radiant Heating and Cooling + DOAS systems."
A solar ready building is engineered and designed for solar installation, even if the solar installation does not happen at the time of construction. The solar ready design features, if considered early in the design process, are typically low or no cost. Attention to building orientation, available roof space, roof type, and other features is key to designing solar ready buildings.
