Historic Palace Going Green to Safeguard its Future

Blenheim Palace is championing the use of alternative energy within historic properties to help protect their future.

The Oxfordshire UNESCO World Heritage Site has instigated a series of environmental initiatives in a bid both to reduce its reliance on traditional energies and its overall carbon footprint.

Among the most significant improvements are a 42% reduction in overall mains water consumption from 2013, the lowest electricity usage figures in five years and an 81% reduction in its use of heating oil.

The estate has also made major investments in upgrading its heating systems, including the installation of two bio-mass boilers in the Pleasure Gardens and its Park Farm maintenance workshop, and a phased move from a steam to a water-based heating system for the Palace.

This has resulted in the lowest gas consumption figures for three years and a 5% reduction in the consumption per degree day - indicating the duration and severity of cold weather - from 1,110 kWh in 2014 to 1,063 kWh in 2015.

Blenheim Palace has also invested heavily in solar panels and replacing traditional lights with more energy efficient alternatives with a third of all lighting within the Palace now being LED.
