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.
Building Energy Software Tools Directory 
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.

Guidebooks and Documents
Energy Savers
Interactive web site developed by NREL to help consumers identify simple energy saving opportunities around their homes.
Builder's Guides
These guides, developed by Building Science Consortium for Building America, contain construction details for new houses and additions in four climate regions.
Analysis and Evaluation
BESTEST
The BESTEST (Building Energy Simulation TEST) method evaluates design and analysis tools relative to their ability to adequately model the energy performance of buildings.
Energy-10
An award-winning PC-based design tool that helps architects and building designers quickly identify the most cost-effective, energy-saving measures for small commercial and residential buildings.
SUNREL
A detailed hourly building energy simulation program that aids in the design of small energy-efficient buildings. SUNREL is temporarily unavailable.
Rules, Codes, and Standards
Rules, codes, standards, and guidelines for buildings, building equipment, and appliances.
Appliance Standards
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.
Building Energy Codes
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.
