Synthesis & Playbook

Consolidate the series into a practical local playbook: top levers, who controls them, what 'good' looks like, and what to measure next.

Builds on: A1-A10  ·  Leads to: none - this is the capstone session  ·  Cross-series: P11 HVAC, IAQ & Mechanical

P/A bridge: No recommendation is complete unless it names owner, metric, verification method, and cost/performance tradeoff.

Core Concepts

• Not all levers matter equally. Can produce a ranked list of highest-leverage actions.
• Ownership matters more than insight. Each action has a named owner/actor and next step.
• Measurement prevents drift. Can define a measurement plan for the next iteration.

Top CROs by Expected Value

Working estimates for the baseline archetype - ranking basis and dollar values need local verification before advocacy use.

1. DENSITY: Increase effective residential density - $30K mid
2. SIZE: Reduce minimum home size - $25K mid
3. INFRA_BURDEN: Reduce off-site infrastructure obligations - $20K mid
4. PREAPPROVAL: Pre-approve plans/details/archetypes - $15K mid
5. METHODS: Adopt modular/prefabricated systems - $15K mid
6. STANDARDS: Right-size street and parking standards - $15K mid
7. FIN_PREDICTABILITY: Reduced interest, contingencies - $15K mid
8. DURATION: Reduce project duration - $10K mid
9. SHARED_INFRA: Share infrastructure across units - $10K mid
10. UTILITY_FEES: Differentiate tap fees by demand - $10K mid

Playbook by Actor

• Cities / counties: DENSITY, DESIGN_PREDICTABILITY, PREAPPROVAL, PERMIT_FEES, STANDARDS
• Utilities: UTILITY_FEES, SHARED_INFRA, DURATION (connection timing)
• Builders / developers: SIZE, SIMPLIFY, STANDARDIZE, METHODS, EFFICIENCY, DURABILITY
• Lenders / capital: UNDERWRITE, INSURANCE_CREDITS, MITIGATION, GREEN_MORTGAGE
• Community / stakeholders: FIN_PREDICTABILITY (engagement), DENSITY (public acceptance)

Common Ways the Playbook Fails

1. No owner, no action - Assign a named owner and a next meeting date.
2. Picking low-leverage moves - Force every proposal to name the cost element it moves.
3. "Reform" that's unusable - Simplify, publish clear checklists, reduce discretionary uncertainty.
4. No measurement - Track a small set of outcome metrics consistently.

Session Close

Facilitation instruction: Before leaving, each table selects one CE/CRO pair, assigns an owner by name, identifies the data needed to make the case, and schedules a follow-up. No recommendation is complete unless it names owner, metric, verification method, and cost/performance tradeoff.
