TL;DR

This paper introduces the Green Scale Research Tool, a multi-criteria, multi-metric energy analysis framework integrated into early architectural design workflows. It addresses limitations in existing AECO software by enabling holistic, real-time assessment of lifetime energy consumption and operating energy use through advanced modeling, improving design decision-making and environmental impact evaluation during conceptual design.

ABSTRACT

Prevailing computational tools available to and used by architecture and engineering professionals purport to gather and present thorough and accurate perspectives of the environmental impacts associated with their contributions to the built environment. The presented research of building modeling and analysis software used by the Architecture, Engineering, Construction, and Operations (AECO) industry reveals that many of the most heavily relied-upon industry tools are isolated in functionality, utilize incomplete models and data, and are disruptive to normative design and building optimization workflows. This paper describes the current models and tools, their primary functions and limitations, and presents our concurrent research to develop more advanced models to assess lifetime building energy consumption alongside operating energy use. A series of case studies describes the current state-of-the-art in tools and building energy analysis followed by the research models and novel design and analysis Tool that the Green Scale Research Group has developed in response. A fundamental goal of this effort is to increase the use and efficacy of building impact studies conducted by architects, engineers, and building owners and operators during the building design process.

Motivation & Objective

• To address the fragmentation and functional isolation of existing building energy analysis tools used in the AECO industry.
• To overcome the limitations of current tools, including incomplete data models, lack of lifecycle integration, and disruption to standard design workflows.
• To develop a unified, design-integrated tool that supports comprehensive energy and environmental impact assessment during early architectural design.
• To increase the adoption and effectiveness of building impact studies by architects, engineers, and building operators.
• To enable multi-metric evaluation of energy performance across both operational and lifecycle phases within a single analytical framework.

Proposed method

• The Green Scale Research Tool integrates multi-criteria and multi-metric energy analysis directly into the architectural design process, minimizing workflow disruption.
• It employs advanced computational models to assess both operating energy use and lifetime energy consumption across multiple environmental impact categories.
• The tool is designed to be interoperable with existing design software, allowing real-time feedback during conceptual and schematic design stages.
• A series of case studies were conducted to evaluate the state-of-the-art in building energy modeling tools and to validate the proposed framework.
• The research team developed a novel analytical framework that combines lifecycle assessment (LCA) principles with dynamic energy modeling for early-stage design.
• The tool supports multi-objective optimization by providing visual and quantitative feedback on energy performance across various metrics and criteria.
