Prologis partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce annual energy consumption by at least 30% versus pre-retrofit energy use as part of DOE’s Commercial Building Partnership (CBP) program.
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.
A case study of the overview, process, and results of the re-tuning that was conducted in a building in Arlington, Virginia by Vornado Realty Trust in October 2012. Re-tuning provided the facilities management team with the ability to identify and understand building scheduling opportunities that drove significant, low-cost energy savings. Five measures were conducted, many of which pertained to the HVAC system.
The Smart Monitoring and Diagnostic System (SMDS) is a low-cost technology that helps building owners and managers keep rooftop air conditioner and heat pump units (RTUs) operating properly at peak efficiency. The SMDS technology has the potential to significantly benefit small commercial buildings, which predominately use RTUs for space conditioning. Through the Better Buildings Alliance, a field demonstration was conducted at four sites using two SMDS prototypes. This case study provides a summary of the field demonstration results.

Over the course of 5 years, NREL worked with commercial building owners and their design teams in the DOE Commercial Building Partnerships (CBP) to cut energy consumption by 50% in new construction (versus code) and by 30% in existing building pilot projects (versus code or pre-retrofit operational energy use depending on the preference of the Partner) using strategies that could be replicated across their building portfolios. A number of different building types were addressed, including supermarket, retail merchandise, combination big box (general merchandise and food sales), high rise office space, and warehouse. The projects began in pre-design and included a year of measurement data to evaluate performance against design expectations. Focused attention was required throughout the entire process to achieve a design with the potential to hit the energy performance target and to operate the resulting building to reach this potential. This paper will report quantitative results and cover both the technical and the human sides of CBP, including the elements that were required to succeed and where stumbling blocks were encountered. It will also address the impact of energy performance goals and intensive energy modeling on the design process innovations and best practices.
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.
The Department of Energy’s (DOE) Windows Volume Purchase (WVP) program is a market transformation effort that allows potential buyers of highly insulating windows and storm windows to obtain bids from a consortium of qualified window vendors. The program brings together buyers and industry partners to overcome the price barrier of highly insulating windows (a U-factor of around 0.2) and low-E storm windows and to increase their widespread market commercialization for maximum energy savings. This program not only increases the availably of these products, but provides an explanation of benefits associated with these high performance products.
The Rooftop Unit Comparison Calculator (RTUCC) compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost. This web application provides an alternative to complicated building simulation models, while offering more detail than simplified estimating tools that are commonly available. While simplified tools are typically based on full-load efficiencies and full-load equivalent operating hours, the RTUCC accounts for local climate and partial-load, as well as full-load efficiencies.
The Commercial Building Energy Alliances sponsor supplier summits, which allow commercial building owners and operators to communicate their energy-efficiency needs directly to suppliers of building equipment.
