The Next Generation of Sales Generation

RetroSpec.ai delivers AI-powered tools for customer outreach, sales enablement, and proposal generation for the building retrofit industry.

Rapid ProposalGeneration

Sales enablement tool allows for real-time forecasting on-site, and on-demand proposal generation, reducing delays and friction throughout the sales process.

Fast & AccurateRetrofit Forecasts

Advanced retrofit forecasting models set a new standard for accuracy, speed, and accessibility. Novel AI models produce forecasts at an hourly level for detailed cost analysis. Capable of parity with calibrated simulations.

Extensive & Extensible Retrofit Library

Currently includes 26 modeled building retrofits representing a broad set of ECMs, including various heat pump options, multiple window retrofits, wall and roof insulation, economizers, etc. Custom retrofits available.

CALCULATE QUOTES,ROI, & OPEX SAVINGS

Calculate equipment and labor costs, and combine with estimated energy savings and operational cost savings for integrated ROI calculations.

An AI-Powered Tool Suite for Sales

RetroSpec’s dynamic proposal engine combines advanced AI models with an intuitive interface, delivering a user experience that’s accessible for non-technical users and fully tunable for experts.

01

prospect

Quickly evaluate prospective customers using limited information: ML models conditionally forecast building energy load and characteristics, with properties based on what is known already (location, annual EUI or usage, building year, other sparse property info, etc).

02

forecast

RetroSpec’s AI-powered ECM forecasting engine delivers accurate, targeted, and specific hour-by-hour forecasts across our entire ECM library. Calculate complex tariff and emissions scenarios in seconds.

03

propose

Create marketing-quality, customer-ready proposals in minutes–without a site visit. Customize templates to match company branding, and create individual proposal templates for outreach campaigns.
