This study investigates the technical feasibility of achieving carbon neutrality in campus heating through integration of on-site PV or solar thermal and thermal storage systems. Using a simulation case study based on a real, federally owned campus in Ontario, Canada, various scenarios were explored to assess their potential to meet Canadian 2050 net-zero emission targets while minimizing electrical demand. Results indicate that multiple scenarios employing a combination of PV, solar thermal, BTES, and PTES on a district energy system can achieve carbon neutrality. However, variations in annual consumption, peak demand, and land use highlight the trade-offs that exist in evaluating the feasibility of net-zero emission campuses.

摘要

This study investigates the technical feasibility of achieving carbon neutrality in campus heating through integration of on-site PV or solar thermal and thermal storage systems. Using a simulation case study based on a real, federally owned campus in Ontario, Canada, various scenarios were explored to assess their potential to meet Canadian 2050 net-zero emission targets while minimizing electrical demand. Results indicate that multiple scenarios employing a combination of PV, solar thermal, BTES, and PTES on a district energy system can achieve carbon neutrality. However, variations in annual consumption, peak demand, and land use highlight the trade-offs that exist in evaluating the feasibility of net-zero emission campuses.
