Building Technologies Analysis
The Building Technologies analysis supports research and development on technologies and practices for energy efficiency, working closely with the building industry and manufacturers; promotes energy and money-saving opportunities to builders and consumers; and works with state and local regulatory groups to improve building codes and appliance standards.
Described here are 283 energy-related software tools for buildings, with an emphasis on using renewable energy and achieving energy efficiency and sustainability in buildings.
This site includes tables of building energy data, as well as EIA information.
Researchers and analysts in NREL's expertise in solar applications includes solar water heating, polymer materials, freeze protection, system certification, solar absorption cooling, transpired solar collectors, PV technologies, testing, building integration, codes and standards, solar resources, and financing.
NREL helps states and local communities throughout the United States achieve their clean energy goals by supporting renewable energy and energy-saving projects through a variety of technical assistance and technology deployment programs.
NREL supports various federal agencies, including the U.S. Department of Energy (DOE), U.S. Department of Defense, and others by providing technical and project assistance, training, and resources to help meet and exceed energy and environmental targets.
ORNL provides specialized expertise in the areas of heating and cooling equipment, compressor retrofits, and HVAC test facilities.
ORNL provides expertise in building envelope systems, including advanced wall systems, moisture control, roof coatings, hot-box testing, and evacuated panel super-insulation.
These programs include a Weatherization Assistance Program, Rebuild America technical assistance, Partnerships for Affordable Housing, State Energy Program metrics and evaluation, and programs focusing on the effects of utility restructuring on low-income customers.
LBNL conducts extensive research into advanced windows technologies, coatings, optical testing, and software.
PNNL provides expertise on building energy codes, including model energy code development, removal of code barriers, and compliance tools; and provides technical assistance and grants for states to implement energy codes and training.
Guidebooks and Documents
Interactive web site developed by NREL to help consumers identify simple energy saving opportunities around their homes.
These guides, developed by Building Science Consortium for Building America, contain construction details for new houses and additions in four climate regions.
This document collection contains links to NREL research papers about Home Energy Rating Systems and Energy-Efficient Mortgages.
Analysis and Evaluation
The BESTEST (Building Energy Simulation TEST) method evaluates design and analysis tools relative to their ability to adequately model the energy performance of buildings.
A detailed hourly building energy simulation program that aids in the design of small energy-efficient buildings. SUNREL is temporarily unavailable.
Rules, codes, standards, and guidelines for buildings, building equipment, and appliances.
Find out more about DOE's program, the general rules and regulations that manufacturers need to comply with, and the latest information on rulemaking, standards, and test procedures for specific products.
DOE's Building Energy Codes Program is an information resource on national model energy codes. We work with other government agencies, state and local jurisdictions, national code organizations, and industry to promote stronger building energy codes and help states adopt, implement, and enforce those codes.
