Everyone loves to get a new tool that will make their job easier, whether it is a power sander for refinishing furniture or a calculator to help you choose the most cost-effective renewable resource or efficiency measure. Here are some “gadgets” that might be just what you need.
Choose your clean power
The Green Power Partnership, a program of the Environmental Protection Agency, has released a new Green Power Supply Options Screening Tool to help you sort through the different supply options. There are many ways to purchase green power—such as green tariffs, competitive green power products and off-site power purchase agreements—and determining which purchasing method works for you can be difficult.
Users answer a few simple questions about their organizations, including their locations and annual energy consumption. The Excel-based tool will describe which supply options might be most feasible, according to the relevant federal, state and utility policies. Background documents accompany the tool to explain how the results are defined and the logic used to produce the result for each supply option.
Calculate equipment efficiency
The DOE Office of Energy Efficiency and Renewable Energy (EERE) created the Better Buildings Residential Program Solution Center as a repository for the lessons learned from other EERE programs dedicated to improving building efficiency. Utility program administrators will find resources here that help them plan, operate and evaluate residential energy efficiency programs.
The Solution Center has recently been branching out with more information about the technical aspects of home performance programs. A new section focused on technology solutions explores innovative technologies, offers installation guidance and estimates potential energy savings.
New pages highlight HVAC systems and heat pump water heaters, two applications that account for about 67 percent of home energy consumption. Use the reports, best practices and other resources to support program offerings and help you to reach your energy-efficiency program targets.
Identify energy savings potential
Researchers at the National Renewable Energy Laboratory (NREL) have developed ResStock, a versatile tool that takes a new approach to large-scale residential energy analysis.
The ResStock software achieves unprecedented granularity and accuracy in modeling the diversity of the single-family housing stock by combining:
- Large public and private data sources
- Statistical sampling
- Detailed sub-hourly building simulations
- High-performance computing
The research team has run more than 20 million simulations using a statistical model of housing stock characteristics. The results uncovered $49 billion in potential annual utility bill savings through cost-effective energy efficiency improvements.
Using ResStock analysis, utilities can target energy-efficiency improvements to specific customer segments to improve cost-effectiveness. Resource planners can determine which measures and distributed energy resources are best for relieving grid congestion and what housing stock segments can provide the greatest load flexibility.
Utility program managers, municipalities and state energy agencies can use ResStock to identify the most cost-effective—and energy-saving—home improvements. The tool is also valuable for helping cities and states figure out how buildings contribute to energy or emissions targets. NREL is pursuing partnerships with industry to adapt ResStock for specific utility, manufacturer, state and local applications.
NREL will be offering the ResStock software at no cost, leveraging DOE’s open-source building energy modeling ecosystem of OpenStudio® and EnergyPlus™. These cloud-based collections of software tools allow users to model energy use for heating, cooling, ventilation, lighting and plug-and- process loads without a supercomputer.
