Heating - Biomass system - School

Template assignment

Base Case

• 10,000 m² school, heating load is 70 W/m²
• Natural gas fired boiler at 65% seasonal efficiency
• Hot water is 10% of total heating energy
• Fuel rate is $0.40/m³

Proposed case

• 350 kW biomass fired boiler at 70% seasonal efficiency, cost is $180,000
• 10% heating reduction due to energy efficiency measures costing $10,000
• Fuel rate is $40.00/t
• Keep gas boiler for peak loads
• Additional O&M costs is $20,000
