Building & Carbon Profile

Building Type ?What: Determines CRREM carbon pathway and benchmark
Typical: Office, Hotel, Retail, Healthcare
Source: Property classification / lease schedule

GFA (m²) ?What: Gross floor area — used to calculate kgCO₂/m² carbon intensity
Typical: Office: 2,000–10,000 m² | Hotel: 5,000–20,000 m²
Source: Architect's area schedule or property listing

Annual Energy (kWh/yr) ?What: Total annual energy consumption (electricity + fossil fuel)
Typical: Office: 150–300 kWh/m² | Hotel: 250–450 kWh/m² (CIBSE TM46)
Source: Utility bills (12 months) or BER certificate
⚠ Use actual consumption, not design — design often 30% below actual

Scope 1 Emissions (tCO₂/yr) ?What: Direct on-site emissions from fuel combustion (gas, oil, diesel gen)
Typical: Gas-heated office: 10–30 tCO₂/yr per 5,000 m²
Source: Fuel bills × SEAI emission factors 2026
⚠ Don't forget standby generators and gas kitchen equipment

Scope 2 Emissions (tCO₂/yr) ?What: Indirect emissions from purchased electricity
Typical: Irish grid: 0.2241 kgCO₂/kWh (SEAI 2026) — declining annually
Source: Electricity bills × SEAI grid emission factor

Renewable Energy (%) ?What: Percentage of energy from on-site generation or contracted renewables
Typical: Rooftop solar PV in Ireland: 80–150 kWh/m² roof/yr
Source: Energy procurement records / PV monitoring
⚠ Only count REGO-backed or on-site — not "green tariff" marketing claims

Net-Zero Target Year ?What: Corporate or fund-level net-zero commitment year
Typical: 2030 (aggressive) | 2040 (aligned) | 2050 (Paris baseline)
Source: Corporate ESG policy / fund mandate

Planned Decarbonisation Measures ?What: Current status of planned interventions to reduce carbon
Typical: Most buildings at screening stage have "None yet"
Source: Asset manager / sustainability team
