Early Massing Energy Optimization

Generates and evaluates building layouts, massing options, and site plans against energy, daylight, zoning, carbon, and feasibility constraints to support faster, more sustainable design development.

The Problem

“Early-stage building energy and massing optimization for faster, code-aware concept design”

Organizations face these key challenges:

1

Too few design options explored due to time and staffing limits

2

Zoning, parcel, and code constraints are checked manually and inconsistently

3

Energy, daylight, and carbon analysis happen too late to influence concept design

4

Design data is fragmented across BIM, GIS, simulation, and spreadsheet tools

Impact When Solved

Generate and rank hundreds of feasible massing and layout options in hours instead of weeksCatch zoning, daylight, energy, and carbon issues before schematic design hardensImprove design quality through multi-objective optimization rather than single-metric tradeoffsReduce manual coordination across Revit, simulation tools, and feasibility spreadsheets

The Shift

Before AI~85% Manual

Human Does

  • •Interpret site, zoning, and program requirements for concept design
  • •Create a limited set of massing, layout, and site plan options manually
  • •Coordinate separate daylight, energy, carbon, and feasibility reviews across tools
  • •Compare tradeoffs and select concepts for client or developer review

Automation

    With AI~75% Automated

    Human Does

    • •Set project goals, priorities, and acceptable tradeoff criteria
    • •Review ranked options and choose concepts to advance
    • •Resolve ambiguous code, program, or client-driven exceptions

    AI Handles

    • •Generate feasible massing, layout, and site plan options from project constraints
    • •Run and consolidate zoning, daylight, energy, carbon, and feasibility evaluations
    • •Rank alternatives across multiple objectives and surface Pareto tradeoffs
    • •Flag noncompliant or low-performing schemes and explain key failure drivers

    Operating Intelligence

    How Early Massing Energy Optimization runs once it is live

    AI runs the first three steps autonomously.

    Humans own every decision.

    The system gets smarter each cycle.

    Real-World Use Cases

    Generative design studies for Revit building layouts

    Designers tell Revit what they want, such as goals and limits, and the software generates many design options to explore.

    AI-assisted generative building massing and sustainability optimization for SolVista

    The team gives the software the building rules and goals, then it creates many possible building designs and helps pick the few that best balance daylight, facade glazing, and rooftop solar potential.
