Enabling efficient and sustainable energy usage.


Maalka is a mixed-source, digital platform designed to enable energy resource managers such as building owners and local governments achieve efficient and sustainable utilization of energy resources.

The challenge

Energy resource managers need to manage toward specific energy-consumption goals, but lack the tools for tracking progress in meeting those goals and leveraging information to further optimize energy usage.

The solution

To address this challenge, John Teeter and the Maalka team developed a mixed-sourced (combination of open-source and proprietary technologies), sustainability-as-a-service platform. The platform features automated data ingestion of both custom and standardized representations; a modularized, extensible architecture to support a variety of sustainability initiatives flexibly; and a standards-based architecture leveraging the U.S. Department of Energy's Building Energy Data Exchange Standard and Standard Energy Efficiency Data Platform to maximize reuse and interoperability.

The results

Thus far, notable results include:

  • Adopted by a number of customers in support of their initiatives at city, state, and national levels
  • Attracted an ecosystem of collaborators who are extending the platform's core services through open-source components and analytics (for example, benchmark, squants)
  • Received "best application" award at the U.S. Department of Energy’s Better Buildings Summit
  • Selected into Wells Fargo's Innovation Incubator program, which is co-administered by the U.S. Department of Energy National Renewable Energy Laboratory
