Commercial Building Energy Audit Optimizer
Analyze commercial building energy data and quantify retrofit ROI with benchmarking
What You Can Do
You can convert raw utility bills, equipment specs, and building data into prioritized, financially justified retrofit recommendations. This skill analyzes 12+ months of consumption patterns, models specific equipment upgrades (HVAC, lighting, controls, envelope), benchmarks performance against industry standards like ENERGY STAR, and delivers client-ready reports that quantify energy savings, payback periods, and implementation ROI.
Features
Extract consumption patterns, demand peaks, and anomalies from 12+ months of billing history to establish accurate baselines
Model retrofit scenarios for HVAC systems, lighting, building controls, insulation, and other major end-uses with realistic efficiency improvements
Compare building performance against ENERGY STAR, ASHRAE, and local compliance standards to identify underperforming systems
Rank improvement opportunities by energy savings potential, capital cost, payback period, and implementation complexity
Calculate annual energy cost reductions, simple payback, NPV, and IRR for competing retrofit packages
Generate measurement and verification plans for performance contracts and utility rebate program documentation
Align recommendations with local energy codes (Local Law 97), tax incentive eligibility, and utility rebate program requirements
Structure audit findings with executive summaries, detailed system analysis, savings calculations, and phased implementation roadmaps

Example 2: Lighting & Controls Upgrade
Input: 500 fixtures (mostly 4-lamp T8 fluorescent, no occupancy sensors), 8,000 sq ft retail
Output:
- Current lighting energy: $24,500/year
- LED + occupancy sensor retrofit: $8,200/year (67% reduction)
- Implementation cost: $42,000 | Payback: 2.1 years
- 10-year savings: $162,300
- Benchmark: Building currently at 1.8 W/sq ft; upgraded to 0.6 W/sq ft (ENERGY STAR compliant)
Example 3: Multi-System Retrofit Package
Input: Full building assessment (office, retail, parking garage)
Output: Phased roadmap:
- Phase 1 (Year 1): Lighting + controls ($185K investment, $45K annual savings, 4.1 yr payback)
- Phase 2 (Year 2): HVAC optimization ($320K, $78K annual, 4.1 yr payback)
- Phase 3 (Year 4): Envelope improvements ($450K, $42K annual, 10.7 yr payback)
- Combined 10-year savings: $1,850,000

You can search Wikidata using four complementary methods: keyword search via the Action API for label-based lookups, semantic/hybrid search through the Vector Database for fuzzy concept matching, direct entity retrieval via Special:EntityData for instant JSON data, and SPARQL queries through WDQS for complex graph relationships and reporting. Each method is optimized for different use cases—from quick entity lookups to multi-table data analysis across millions of linked facts.
