Climate risk and innovation take center stage on the pathway to net zero emissions
With a net zero emission goal for 2050 on the horizon, Hennepin County in Minnesota is looking to reduce carbon consumption across their property portfolio of 77 buildings, spanning over 6 million square feet (557,418 square metres). They engaged us to help with the energy transition for these buildings.
We performed a building system decarbonization study and recommended strategies to reach net zero greenhouse gas emissions by 2050. While reviewing numerous carbon emission reduction principles, we considered climate risk mitigation. To make the most of the existing embodied carbon portfolio, we looked at the reuse of existing buildings, structures, and materials. Our team prioritized energy reduction through passive design strategies and efficient systems. We conducted a comprehensive solar photovoltaic feasibility assessment across the portfolio that considered electrical and structural constraints and life cycle cost assessments.
To reduce dependence on natural gas, we proposed innovative techniques, like using carbon-free electricity for heating. Where full decarbonization implementations were cost-prohibitive or infeasible, our recommendations included alternative strategies to offset remaining emissions, such as using renewable natural gas or purchasing renewable energy credits.
These recommendations align with the County’s Climate Action Plan goals—to reduce, eliminate, and offset carbon energy sources—and can help the County plan for net zero buildings by 2050.
