You cannot decarbonize or recover a multi-tenant asset with landlord-only emails. Data access, retrofit disruption, and emergency instructions all require a communication system.
Message types
- Data-sharing request — meters, after-hours use, submeter access
- Retrofit notice — timeline, noise, access, benefits
- Emergency / continuity — where to go, who decides re-entry (PM continuity playbook)
- ESG program update — honest, non-greenwash progress
- Lease cycle — green-lease clauses in plain language
Cadence

Template — data request (short)
Subject: Building energy data partnership — [Building]
Body: purpose · what data · how used · privacy · deadline · PM contact · optional incentive
Template — incident
What happened · safety status · what tenants should do · what not to do · next update time · hotline
NYC buildings: keep filing-season noise out of incident messages. LL97 belongs in the annual / quarterly packet, not the all-clear.
