Energy Saving Sustainable Technologies
The project, contributing to minimising the carbon footprint of the site utilises renewable technologies such as Air Source Heat Pump (ASHP), log boiler, solar thermal panels and wind turbines. Partial funding to procure these was made available by Community Energy Scotland (CES) and Energy Saving Trust (EST) Scotland
Eco heating systems
Endevouring to be a low carbon community, some of the major buildings at Karuna Bhavan have recently undergone reconstruction and have been insulated to minimise the heat requirements. The heating and hot water are supplied through a well insulated, district heating pipe-work - by a Frohling S4 Log Gasification Boiler of 50kW capacity which has a 4400 litre thermal store. The boiler and thermal store are in a containerised unit within the large warehouse where we cut and store our logs. The boiler feeds the under floor heating system and radiators. Also, Solar Thermal Panels have been installed on the south facing roof of Gouranga Hall. These supply domestic hot water and heating along with the log boiler for two of the community buildings.
To help reduce the environmental impact of our electricity consumption, in 2011, we installed two Gaia 11kW wind turbines with the financial backing of Energy Saving Trust (EST) Scotland to help generate green electricity. One of the wind turbines is linked into the electricity supply for the ASHP while the other is linked to the Bio-Mass Boiler. Surplus electricity generated is exported to the national grid.
We have a water system, whereby rainwater is collected from the roof of Gouranga Hall and stored in 6000 litre water tanks for the Project needs in the walled garden.
Greenhouse & Air Source Heat Pump (ASHP)
One of the three greenhouses is heated via an Air Source Heat Pump (ASHP) supplying a heated floor specially designed for greenhouses with de-stratification fans on the ceiling to prevent hot air from escaping through the glass roof.
Savings on energy costs will be used to make further improvements to the site to make it more sustainable and to be able to offer services at a low cost or free of charge for the local and wider community and visitors from further afield, schools and other organisations.
