Water

The irrigation system at the Golf Club de Lausanne underwent a major overhaul in 2015, resulting in greater efficiency thanks to an automated and programmable system. In terms of basic operation, the water that feeds the sprinkler system is taken from 2 interconnected outdoor reservoirs located to the west of the course towards holes 2, 15 and 16.

• The upstream (upper) reservoir has a surface area of about 1,500 m2 and an average depth of around 2 m, giving it a storage volume of just under 3,000 m3.
• The lower reservoir has a surface area of approximately 1,500 m2 and an average depth of around 2.5 m, giving it a storage volume of around 3,500 m3.

The reservoirs are fed by:

• firstly, run-off (rain) and drainage water from the course (including the return of irrigation water), which can be collected.
• secondly, the City of Lausanne's drinking water distribution network, which supplies the rest of the water required and which is discharged into the reservoirs.

The Golf Club de Lausanne's irrigation policy aims to minimise the amount of water drawn from the city network. Major efforts are therefore being made to recover all the rainwater falling on the surface of the golf course and its buildings.

Changing climatic conditions have prompted the Golf Club de Lausanne Committee to launch a wide-ranging review of future water needs and how to ensure that supplies are as sustainable as possible, whether they come from run-off water, the City of Lausanne or any new underground boreholes. Studies are underway, including the construction of new storage capacity, to ensure maximum autonomy.

Electricity

The Golf Club de Lausanne's total electricity consumption is around 195 MWh/year, and this is set to increase as we electrify our fleet of course machinery in particular.

The photovoltaic solar panels already installed on the farm shed produce around 28 MWh/year. We are planning to install an additional capacity of around 245 MWh/year on a free area and on the car park at Antets Farm, so that, combined with storage capacity, we could approach a self-consumption rate of around 65 to 70%.

Heating

Since 2022, the clubhouse has been heated by a pellet-fired system that has replaced the old oil-fired heating system, which had reached the end of its useful life.

In 2011, we had already replaced the oil-fired boiler with a pellet-fired boiler at Antets Farm, which houses the course maintenance facilities and accommodation for the caddies.
