AN INTEGRATIVE BUSINESS MODEL FOR NET ZERO ENERGY DISTRICTS

The Rocky Mountain Institute presents a business model for net zero energy (NZE) districts that achieves life-cycle cost neutrality compared to business-as-usual (BAU) developments. The model centers on an Integrated Energy Services Provider (IESP) that manages a micro-utility, district heating and cooling, and renewable energy deployment. By shifting capital costs for heating/cooling and solar PV away from parcel developers and providing on-bill financing for energy efficiency, the model reduces upfront costs for developers and lowers total energy bills for tenants. The approach includes outcome-based energy-performance requirements enforced through a system of incentives and penalties. A case study of a 180-acre mixed-use development in a midsize U.S. city demonstrates that the model remains economically favorable even under challenging conditions such as low electricity rates and a lack of net metering.

• The proposed business model aims to make NZE districts life-cycle cost neutral or better than business-as-usual (BAU) developments, while specifically reducing first costs for parcel developers.
• The model utilizes an Integrated Energy Services Provider (IESP) to act as a multipurpose developer, financier, operator, and administrator of energy systems, managing functions such as a retail electricity micro-utility and district heating and cooling.
• To ensure financial attractiveness for parcel developers, the model removes the capital costs of solar photovoltaics (PV) and heating/cooling equipment from the buildings and provides on-bill financing for incremental energy efficiency costs.
• Tenants in NZE districts are expected to pay a total energy bill—comprising electricity (including PV costs), district heating/cooling, and on-bill efficiency loan repayments—that is lower than a BAU tenant's energy bill.
• The model implements outcome-based energy-performance requirements based on energy use intensity (EUI), using a revolving fund fueled by penalties from noncompliant buildings to maintain the district's NZE status.
• A case study of a 180-acre, 6 million square foot mixed-use brownfield site in a midsize U.S. city showed that the NZE model's first costs and annualized life-cycle costs were on par with or cheaper than BAU, despite low electricity rates and no net metering for rooftop solar.
