Net Zero Energy Design

Net zero energy occurs when local renewable sources produce an amount of energy equivalent to what the project consumes, thus balancing supply with demand and creating a net zero loss in energy. LHB has conducted several net-zero and net-positive energy studies to analyze how to achieve these ambitious goals at the building to neighborhood scales.


  • Net-zero and net-positive energy analysis and design
  • Design of renewable energy systems

Beyond Zero, A Cost-Effective Approach to Developing a Net-Positive Energy Warehouse

The St. Paul Port Authority, LHB’s client, has a goal to develop a net-zero energy warehouse by 2020. Our team was commissioned to identify the “most probable path to building a net-zero energy warehouse” to assist in achieving this goal.

This feasibility study investigates this question through four parts: a high-performance design guide specific to office-warehouse buildings in Minnesota, a prototypical concept building design, a concept design pricing exercise, and an analysis and recommendation on the most cost-effective approach to developing a net-zero energy office-warehouse building.

Using an integrative process, this study benefitted from the insight and expertise of a diverse team of building professionals, owners, and operators.

Railroad Island Net Zero Energy Neighborhood Plan

LHB worked with Dayton’s Bluff Neighborhood Housing to create a plan that directs the Railroad Island community in St. Paul toward achieving net-zero energy use by 2030.

The study surveyed existing site conditions, calculated baseline energy consumption, established energy targets, identified opportunities to reduce building energy consumption, provided cost estimates for reduction strategies, and proposed local renewable energy production alternatives.
