Eight capabilities that close audits

01

Accuracy & Consistency

A physics model that passes BESTEST standards, with cascading inputs and region-age defaults so every audit starts from a sensible, defendable baseline.

  • BESTEST-compliant hourly modeling of the current home and every alternative package simultaneously
  • Model settings update with every input so you always get the best model for available information
  • Region- and age-aware defaults avoid inappropriate assumptions (e.g. basements in Florida)
  • Cascading inputs — area drives length, width, volume, windows, and foundation dimensions
02

Self-Calibrating Audit Wizard

A streamlined wizard with live load charts and automated utility calibration — so auditors discover savings opportunities in real-time instead of truing up models after the fact.

  • Realtime feedback from 40 continuously updated hourly models
  • Wizard focuses on high-impact inputs (with one-click access to full detail tabs)
  • Specify ranges for uncertain values — the wizard calibrates within those bounds
  • Automated utility calibration builds the best model true to all available information
03

Powerful Utility Analysis

Careful utility handling turns bills into a calibration signal: weather matching, outlier flagging, delivered fuels, and BPI-2400-ready workflows.

  • Current weather for 1,000+ locations, matched automatically to bill periods
  • Estimated, vacation, and outlier bills flagged and handled correctly
  • Automated calibration so the model agrees with utility usage
  • Delivered fuels, multiple heating fuels, wood/pellet support, and BPI-2400 compliance
04

Custom Reports

Fast, stable report generation to PDF, DOC, and DOCX — with factory templates, photo slots, and a WYSIWYG editor over thousands of project variables.

  • Over 50 dynamic pages; PDF reports with dozens of editable photo slots
  • Brand covers and headers with your logo; save page selections for reuse
  • Charts, improvement tables, incentives, financing, and component narratives
  • Bundle external PDFs and build custom content blocks from OptiMiser variables
05

Detailed Financial Analysis

Configure financing and incentives once, then compare packages on SIR and modified internal rate of return — including periodic maintenance costs that often get left out.

  • Flexible loan and financing analysis with simple configuration
  • Up to five incentives per improvement — fixed, percent, cost-based, or formula
  • Periodic O&M costs included in cash-flow analysis
  • SIR with or without incentives, plus modified internal rate of return (MIRR)
06

Renewable Systems Support

Model efficiency and renewables together — panel and inverter databases, automatic array layout from roof dimensions, and payback metrics that include SIR and MIRR.

  • 2,800+ solar panels and 600+ inverters in the PV module
  • Automatic array configuration from roof dimensions
  • Dynamic graphs of production, solar fraction, and net metering
  • Solar thermal f-Chart analysis with 400+ panels for DHW and space heat
07

Advanced Modeling Features

Support for the building details that change savings estimates — so guidance stays accurate when homes are anything but simple boxes.

  • Window overhangs and shading, mass walls, reflective barriers, BASESIMP ground coupling
  • ASHRAE 152 duct analysis and EnergyStar appliance databases
  • Pool pumps, 120+ miscellaneous loads, BPI combustion-safety (CAZ) analysis
  • Ventilation standards, heating/cooling design loads, and a customizable interface
08

Efficient Sales Tool

Win customers with accurate information in a compelling format — from one-button package ranking to touch-optimized tablets that capture signatures without a scanner.

  • One-button generation of ranked packages optimized for payback
  • Compare up to 10 packages for savings and cost-effectiveness
  • Automated form filling and on-tablet signature capture to PDF
  • Touch-optimized interface that resizes for Windows tablets in the field
