The Golden Jubilee HospitalThe Golden jubilee hospital was selected as the case study for the project. The hospital was build in 1994 and was originally built to be used as a private hospital to be run by an American company. With this in mind the hospital was built with a focus on comfort levels for the patients which has resulted in a particularly comfortable and pleasant facility. Part of what makes the facility comfortable is the fact that a large amount of Air Conditioning is present throughout the building. This air condition is however a large part of the facilitys energy demand and will be addressed as part of the project. As well as HVAC (heating Cooling Air Conditioning) within the facility their is also radiator heated areas where only air supply and extract is present. The diagram below shows the area's where the hospital is heated by the HVAC system along with the areas that are radiator heated. The Blue Line is the external boundry of the HVAC system and internal boundry of the Radiator system, whislt the red lines form the external boundry of the radiator system.  The hospital energy demand has been captured by the graphs shown below. these allow us to gain an appreciation of the energy requirement of the hospital. it will also give us something to use to compare with and clarify modelling results.  From looking at the hospitals electricity usage over 2009 no clear pattern of electricity usage appears, suggesting that the electricity is not affected largly by seasonal effects and is possibly more reliant on equipment usage within the hospital. With regards the annual electricity usage it is clear that the usage has been increasing over the past 5 years, however it has not been a constant increase and has instead been over 2 separate steps. The stepped increase suggests that major changes within the usage of the facility may have contributed to the increase. One notable change that could have been involved is the change of use of part of the hospital from hospital space to NHS 24 call centre space. This is likely to mean a different level of demand being present within the hospital.  The gas usage over 2009 shows more of a pattern slightly following the traditional U-shaped usage pattern. This is obviously due to the increased demand in the winter when the heating demand increases. It is notable that the demand does not fall away completely in the summer which could be due to the fact that gas is still required for cooking purposes and also for use in sterilising equipment within the hospital. The annual gas usage has been increasing in a more consistant fashion than that of the electrical usage, however obvious weather conditions can affect this on a yearly basis. |
