There is nothing small about the impact that small commercial buildings have on energy use in the United States. In fact, the 4.6 million small buildings across the nation consume 44% of the overall energy use in buildings, presenting an enormous opportunity to cut costs, energy use, and greenhouse gas emissions. Despite this potential, small building owners and operators face unique challenges that have historically impeded the adoption of widespread energy efficiency solutions. A new report developed by the National Renewable Energy Laboratory (NREL) examines these barriers and suggests a path forward to support cost-effective energy savings for the small buildings and small portfolios sector, which typically has limited resources to pursue energy efficiency solutions.

Small buildings have been left behind in the energy efficiency marketplace because financial and technical resources have flowed to larger commercial buildings (PGL 2013). DOE’s Building Technologies Office (BTO) works with the commercial building industry to accelerate the uptake of energy efficiency technologies and techniques in existing and new commercial buildings (DOE 2013). BTO recognizes the SBSP sector’s potential for significant energy savings and the need for investments in resources that are tailored to this sector’s unique needs. The industry research and recommendations described in this report identify potential approaches and strategic priorities that BTO could explore over the next 3–5 years that will support the implementation of high-potential energy efficiency opportunities for this important sector.
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.
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 primarily applies to facility managers and energy managers of large existing office buildings larger than 100,000 square feet, but also includes considerations for small and medium office buildings. By presenting general project planning guidance as well as financial payback metrics for the most common energy efficiency measures, this guide provides a practical roadmap for effectively planning and implementing performance improvements for existing buildings.
Retail buildings in the U.S. are second only to office buildings in total energy consumption and represent approximately 13% of energy use in commercial buildings nationwide. The Advanced Energy Retrofit Guide for Retail Buildings presents general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures to provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. This guide is primarily designed for facility managers and energy managers of existing retail buildings of all sizes.
This guide was created to help healthcare facility decision-makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
The Advanced Energy Retrofit Guide for Grocery Stores was created to help grocery store decision makers plan, design, and implement energy improvement projects in their facilities. It was designed with energy managers in mind, and presents practical guidance for kick-starting the process and maintaining momentum throughout the project life cycle.
The Advanced Energy Retrofit Guide for K-12 Schools is one of five retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as more detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures, the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The K-12 Schools guide provides convenient and practical guidance for making cost-effective energy efficiency improvements in public, private, and parochial schools.
