Owners and Renters Collaborate to Reduce Energy Use
"By mandating that large residential buildings disclose their energy use, Tokyo is getting tenants and owners to collaborate on prioritizing energy efficiency upgrades.
Large residential buildings included in Tokyo’s Cap-and-Trade Program must report their energy use and efforts to reduce consumption, under the city’s mandatory Tenant Rating and Disclosure Program. As part of the program, each apartment unit receives an evaluation and a grade, which is disclosed on the city’s website. While Tokyo already works with owners to reduce energy use, tenant engagement is essential to accelerate the uptake of energy efficiency upgrades. The program not only increases awareness and transparency, but also incentivizes owners and tenants to collaborate by making tenants responsible parties. In addition, the city supports the disclosure program by providing important information on how to improve energy performance, as well as pilot projects for retrofits and environmental performance attached to leases."
