PUBLIC Data toolkit

Maalka is always developing new public and open-source tools to help users manage their data-driven programs. On this page, you will find three tools for helping you understand the quality of your data and the performance of your buildings. The tools were developed in collaboration with industry leading partners and are free to use and even customize.


  • PARTNER: Developed with support from the Department of Energy
  • Purpose: The Data Validation Tool allows users to easily import their EPA Portfolio Manager data and automatically identify data anomalies across their building portfolio. Cities may use the tool as a first step to improving data quality before engaging in data analysis.

  • PARTNER: Developed with support from the Northwest Energy Efficiency Alliance
  • Purpose: The Temperature Sensitivity Tool helps users understand how their building energy-use varies with temperature. The tool takes in a spreadsheet and outputs a visualization and parametric model, which can be used to normalize for weather and measure changes to energy-use over time.

  • PARTNER: Architecture2030
  • Purpose: The Zero Tool is used to compare building energy-use intensity with similar building types across the country. The tool leverages the 2003 CBECS dataset to maintain pre-existing goals and baselines so that progress can continue to be consistently measured.
