GRAND HOTEL UNION
Company: Grand Hotel Union – Slovenia
Grand Hotel Union is a historic 4-star accommodation in the heart
of Ljubljana. Built in 1905 by architect Josip Vancaš in the Art Nouveau style, the construction of the Grand Hotel Union was a great event for the time and over the years has hosted political, film, musical and royal celebrities, including the British Queen.
Even today Grand Hotel Union maintains its splendid Slovenian style and character, but at the same time offers the modernity of the largest conference center in Ljubljana, which can accommodate
up to 800 guests with a wide range of services and event spaces.
Given its status as a historic and famous hotel throughout Slovenia with a strong sensitivity to the environmental sustainability, the customer was looking for an effective efficiency solution, which would guarantee verifiable energy savings and the monitoring of energy data.
In January 2020, was installed a 1,250 A E-Power device downstream of the general switch that powers all of the hotel’s machinery
and services. The configuration of the electrical loads powered by this line consists mainly of machinery with and without inverter, air conditioning and lighting, for a used power of about 760 kW and
an energy consumption of about 3,500,000 kWh:
• Heating, Ventilation and Air Conditioning: 41%
• Inverter Machinery: 35%
• Non-Inverter Machinery: 13%
• Traditional lighting: 8%
• LED lighting: 3%
