• Valencia has a Subtropical Mediterranean climate. The annual average temperature is 17.8 °C,

• Residential use building: – Constructed in 2001– 4 floors – 12 flats – total floor area of 610 m2

• Annual energy consumption is 61 kWh/m2

– 54 kWh/m2 natural gas, – 7 kWh/m2 from electricity.

• The annual thermal needs are 23 kWh/m2 for space heating,

• 25 kWh/m2 for DHW • 22 kWh/m2 for space cooling

• Updated thermal energy generation system consists of:– A solar thermal field, – Adsorption pump unit, – Three air-water electric heat

pumps,– Three water tanks (heat and

cool)• The system generates the heat and

cooling of DHW and air conditioning demand.

• The heat and cold energy are stored in the heat and cooling water tanks and supplied to the DHW and heating/cooling distribution circuits.

• Solar thermal array connected to two thermal stores,

• The solar heat transfer is controlled by an algorithm in the SCI-BEMS:– The objective is

maximizing the energy efficiency of the system;

– The heat can be used for:• Cooling, • Also for domestic hot

water purposes,• And space heating.

• Objectives:– Generate energy savings in

heating, cooling and domestic hot water of 30% through renewable generation sources,

– With a less that ten years payback period.

• Results according to simulations:– Solar thermal system covers till

the 52% of the heating (SH+DHW) energy needs,

– The system provides a total cooling energy production up to 27%.
