The 210 room Hotel Hemus in Sofia (85 employees) carried out a cleaner production (CP) and corporate social responsibility (CSR) audit in order to make energy savings and at the same time qualify for a green hotel label. The audit led to several measures including the replacement of old washing machines and an ironing press with more energy-efficient models. The CSR audit led to staff motivation schemes, better working conditions and modernization of staff rooms, and the introduction of a management certification scheme. Implementing the Cleaner Production measures led to a saving of 150 MW per year and reduction of CO2 emissions. CSR measures resulted in: clear bonus systems based on individual motivation and better working conditions and atmosphere; better management practices and higher staff qualifications; increased social security benefits; higher quality of service and overall increased revenue for the hotel.
