In the very first myclimate project, the business school INCAE in Costa Rica, together with myclimate, replaces a diesel burner for the hot water preparation with a solar installation. In addition, the energy efficiency is improved through the restoration of the water pipes.

This first myclimate project was launched at the annual meeting of the AGS (Alliance for Global Sustainability) in March 2002, together with the business school Instituto Centroamericano de Administraciòn de Empresas (INCAE).

With this, the INCAE school, one of the leading training centres of its type in Central America, set an example for climate protection and for the switch to renewable energy sources. With the help of myclimate, the existing diesel burner for water heating was replaced with a solar installation (16.4 m² collector area with a gas boiler as replacement heating). Through the additional renovation of the hot water pipes, the energy efficiency of the system could be increased even more, subsequently leading to higher diesel savings.

The hot water supplies both the kitchen and the shower rooms of the school, and was supplied prior to the project by the central diesel firing via long water pipes. The project, however, relies on two separately located collectors and two insulated reservoirs.

Both students and professors of the INCAE were involved in the project from the beginning, and substantially contributed to its successful monitoring and maintenance. Through its academic background, this project shows great demonstration and multiplication potential in the region.

Since its start-up in 2002, 2,200 litres of diesel have been saved though the project each month (less the gas consumption for the backup boiler).

* In October 2008, after a 5-year run, the project was concluded as a successful offset project so that no new emission reductions are purchased from the project. However, the on-site plant continues to run perfectly.
