Summary
The application of Passive Downdraught Evaporative Cooling (PDEC) to the central atrium space within the New Stock Exchange in Malta, demonstrates the viability of its wider application Southern Europe, both to new buildings and in refurbishment projects. PDEC meets approximately 25% of the cooling requirement and the residual load is met by chilled water cooling coils. The system avoids the needs for conventional air conditioning and saves approximately 50 kWh/m2/year. The building was completed in 2001.
Results
The potential savings for the atrium space alone represent over 60% of the predicted energy consumption for large fan coils units. The general building improvements (shading, insulation, night ventilation) also benefit the cellular office accommodation, reducing the energy consumption of the cassette units by approximately 23%. The total cooling energy consumption for the whole building using fan coils was estimated at approximately 103 924 kWh, compared with 54 139 kWh for the built solution using cooling coils and PDEC, resulting in a total energy saving of 48%. This represents an annual saving of £ 3 080/year based on £ 0.06/kWh. The economic benefits are capital and running cost savings and the environmental benefits are reduction in CO2 emissions by approximately 28 152 kg CO2.
