Commercial space conditioning (heating, cooling, and ventilating) accounts for about 7.0 quads of primary energy per year, or about 40% of total commercial energy use in the United States. Through the Space Conditioning Technology Research Team, partners work together to deploy energy-saving space-conditioning strategies by partnering with industry on the Advance Rooftop Unit Campaign, coordinating real world building demonstrations, and generating tools to help partners understand and improve the performance of HVAC systems.
Better Buildings partners participate in webinars, peer-exchange calls, meetings, and industry workshops and conferences. Browse upcoming events and opportunities to participate by month.
Through the Better Buildings Alliance, over 200 public and private sector organizations across the country are working together to share and replicate positive gains in energy efficiency.
The 2019 Better Buildings, Better Plants Summit is happening July 10-11 in Arlington, VA. Don't miss this opportunity to explore emerging technologies and share innovative strategies in energy and water efficiency alongside peers.
HVAC Resource Map Technical AssistanceThe HVAC Resource Map is an intuitive graphical interface that provides quick access to a broad array of quality information on operations and maintenance best practices and energy and water efficiency measures.
RTU Inventory Spreadsheet
The rooftop unit inventory spreadsheet can be used to gather basic RTU information in a streamlined evaluation process.
RTU Field Evaluation Checklist
The RTU Field Evaluation Checklist is a visual-based field evaluation to help identify damage, dysfunction, or degradation that requires more than routine maintenance.
Advanced Energy Retrofit Guides
The Advanced Energy Retrofit Guides (AERGs) provide practical roadmaps and example efficiency measures for effectively planning and implementing performance improvements in existing buildings. The AERG series covers K-12 schools, retail buildings, grocery stores, office buildings, and healthcare facilities.
Buildings Re-tuning Training
Re-tuning is a low-cost process to identify and correct building operational problems that lead to energy waste. The Department of Energy and the Pacific Northwest National Laboratory developed training curricula focused on re-tuning large and small commercial buildings.
ENERGY STAR Building Upgrade Manual
This manual contains energy-saving building upgrades and cost-effective retrofit opportunities. See Chapter 5 for retrocommissioning, Chapter 8 for air-distribution systems, and Chapter 9 for heating and cooling upgrades.
Federal Energy Management Program (FEMP) purchasing requirements
A FEMP resource on procuring high-efficiency products, many not covered by ENERGY STAR®. Although developed for a federal audience, they can apply to the private sector. See also the FEMP energy and cost savings calculators for energy efficient products.
