User-friendly, yet highly sophisticated, residential energy analysis, code compliance and rating software developed specifically for the needs of HERS providers. REM/Rate calculates heating, cooling, hot water, lighting, and appliance energy loads, consumption and costs for
new and existing single and multi-family homes. Climate data is
available for cities and towns throughout North America. A home
energy rating is calculated based on the proposed DOE HERS
guidelines (10 CFR 437) as modified by the RESNET/NASEO HERS Technical Committee. In addition to an energy rating, REM/Rate creates value added information including energy efficiency mortgage report, energy appraisal addendum, energy code compliance (MEC, IECC, and ASHRAE), improvement analysis (existing homes), design optimization (new homes), heating and cooling equipment sizing, utility DSM compliance analysis, and U.S. EPA Energy Star Home analysis.
�
REM/Rate operates in Windows and has many unique features, including a simplified input procedure, extensive component
libraries, automated energy efficient improvement analysis, duct conduction and leakage analysis, latent and sensible cooling analysis, lighting and appliance audit, and active and passive solar analysis. In addition, REM/Rate has a User Defined Reference Building feature which enables the HERS provider to create other reference buildings that can be compared to the
rated home, and an Export/Archive File feature that creates a file of inputs and outputs that can be imported to database software for statistical analysis, rating archiving and custom report generation.

Validation/Testing
N/A
Expertise Required
Medium level of computer literacy required.
Users
REM/Rate is used by utilities, HERS Providers, weatherization agencies and others in over 35 states for energy design assistance, residential DSM programs, weatherization assistance programs, and home energy rating programs.
Audience
HERS Providers, weatherization agencies, and energy auditing consultants.
Input
Two levels of input: simplified and detailed. Simplified inputs use general building design characteristics (e.g., house type) and built-in algorithms to determine building shell areas and other characteristics. Detailed inputs provide the user greater control over calculational values. Inputs include, opaque wall construction details, window conduction and solar gain values, HVAC efficiencies, duct system characteristics, passive and active solar design features, infiltration rates (measured or estimated).
Output
27 preformatted reports, available for viewing on screen or printing. Reports include rating, quick report, improvement analysis, energy use, energy cost, normalized energy use, design loads, code compliance, and economic analysis of energy upgrades.
Computer Platform
Computer Platform: PC-compatible, Windows 95/98/NT/2000/ME, 8 MB disk space
Programming Language
C++
Strengths
Considered one of the easiest residential energy analysis and rating tools to use. One of the only tools that allows
side-by-side comparison of two homes, making analysis of energy upgrades easy. Automatic improvement analysis makes
automated design optimization possible. Multi-purpose tool brings together in a single package the capability to perform home
energy ratings, design optimization, improvement analysis, compliance analysis and equipment sizing.
Weaknesses
Single zone model. Seasonal methodology cannot predict hourly values. Unsophisticated HVAC equipment
modeling.
