Data sources

Residential heating life-cycle data sourced from:

• Bakshi, N., Vale, R. & Vale, B. (2013) “Which heater should I choose? A comparative study of appliances and fuel sources”, Cutting Edge: 47th International Conference of the Architectural Science Association (ANZAScA), pp. 335–344
• Alcorn, A. (2003) Embodied Energy and CO₂ Coefficients for New Zealand Building Materials, Centre for Building Performance Research, Victoria University of Wellington
• EECA (2013) ENERGY STAR appliance ratings and Energy End Use Database — space heating is ~29% of typical NZ household energy
• Ministry for the Environment (2013) recommended low-emission wood burners; NES for Air Quality burner rules
• Rule, B. (2009) New Zealand electricity generation mix — 55.2% hydro, 21.8% gas, 12.2% coal, 7.6% geothermal, 3.2% wind
• Isaacs, N. et al. (2006) Energy Use in New Zealand Households (HEEP Year 10), BRANZ — space heating ≈ one third of household energy
• ISO 14040:1997 Environmental Management — Life Cycle Assessment: Principles and Framework
• World Health Organization recommended minimum indoor temperature 18 °C (16 °C in bedrooms overnight)

⚠️ Life-cycle figures are drawn from a 2013 New Zealand study of a single-room heating regime and are scaled to this building's steady-state heat demand. They exclude installation, maintenance, transport of fuel, comfort and air-quality effects, and assume a fixed electricity generation mix. Use for comparison and feasibility only; confirm appliance selection with the current EECA/manufacturer data and your local council's air-quality rules.
