Energy and greenhouse gas emissions

Approximately 20% of Australia’s Greenhouse gas emissions are from buildings. Electricity and gas consumption are the main components of Greenhouse gas emissions at Parliament House.

  • Gas is used for heating, domestic hot water and catering equipment.
  • Electricity is used mainly for office lighting and power, mechanical services, lifts, chillers, computer equipment, catering equipment, water features, the central waste plant and boosted hot water heating.
  • Diesel and petrol make up the remainder of energy consumed.


Energy conservation at Parliament House has been a high priority since the building was opened in 1988. Achievements include;

  • Electricity consumption reduced by 41%
  • Gas consumption reduced by 75%
  • Greenhouse gas emissions reduced by 51%; and
  • Total energy reduced by 59%

Performance for past reporting periods is available in Environment performance publications.

Energy conservation projects and strategies have included;

  • replacing light globes with energy efficient types
  • adjusting the operating times of lights and equipment so that it operates only when required
  • installing roof-top solar panels
  • installing a smarter building management system; and  
  • upgrading the air-conditioning and hot water systems with more efficient types.

To help Parliament House reduce greenhouse gases further, DPS also purchases 10% accredited renewable energy from sources, that include wind power, solar, mini-hydro and biomass.

We recognise our achievements over the past 25 years in reducing energy consumption and endeavour to further reduce our carbon footprint over the next 25 years.
