現今醫院業不斷地成長，更有效的能源管理是必要的。典型醫院由於中央空調系統佔總能源消耗為50%以上，節省加熱與冷卻系統的運轉成本是典型醫院建築最有效的措施之一。
本研究為大型醫院之節能與效率改善更新計畫，已建立一完整的評估程序且在台灣成功證實。替代熱水系統(即為水源式熱泵)與既設空調系統整合之改造方法；使之滿足冷卻負載與熱水同時需求之能力，具較大的安全裕度，並且也節能。本程序是包括執行現場系統診斷，發展對應的改造策略，執行電腦模擬以評估其有效性，然後進行全尺度實驗，以印證結果。
此外, 整合系統為冷卻提供一新來源，可用作為避免空調主機停機的備用系統。當考量醫院中的特定區域時，這是非常有幫助的，例如:加護病房、手術房。在這些區域的任何時刻，不應中斷空調。
在系統設計與選用過程中，可用能分析確認水源式熱泵優於氣源式熱泵顯著；進一步地，以全尺度實驗證實在加熱與冷卻之個別模式下，新增水源式熱泵系統的性能係數，分別為3.62與2.62。而在個別模式利用電腦模擬結果，皆維持在2.2%至2.6%間的誤差，具非常好的精確度。
本整合系統所記錄的全年成本減少約102,564美元，回收年限為1.2年。改造後的醫院運轉更穩定，更有效節能。這在醫院業中實施，保證有巨大的潛力。

Nowadays, the hospital industry is continuously growing, more efficient energy management is necessary. Due to the HVAC (Heating, Ventilating, and Air-Conditioning) system accounts for over 50% of total energy consumption in a typical hospital, it is one of the most effective measures in saving operation cost of the heating and cooling systems in a typical hospital building.
In this study, a complete evaluation procedure of energy-saving and efficiency improvement for a large-scale hospital retrofit project has been established and successfully validated in Taiwan. The retrofit scheme, in integrating the alternative hot water system, namely, a WSHP or Water-source Heat Pump, with the existing HVAC system, enables the system capability to meet the cooling load and hot water demand simultaneously with a larger safety margin and saving energy as well. The procedure consists of performing the jobsite system diagnostics, developing a corresponding retrofit strategy, performing computer simulation to evaluate its effectiveness, and followed by full-scale experiment to validate the results.
In addition, it has been found that the integrated system provides a new source for cooling which can be utilized as a system redundancy in avoiding system shutdown. This is very useful when considering in specific areas in the hospital, such as intensive care units, or operation rooms, where cooling should not be interrupted in any occasion.
During the system design and selection process, an exergy analysis has identified that the WSHP outperformed the ASHP (Air-source Heat Pump) significantly. It has further been validated by the full-scale experimentation that the COP of the newly added WSHP system, under heating and cooling mode, is 3.62 and 2.62, respectively, which correlated very well with the computer simulation results with deviation kept within 2.2% to 2.6% under each mode.
The recorded annual cost reduction by this integrated system is $102,564, with a payback of 1.2 years. The hospital after retrofit has been operating safer, with more redundancy, and more energy-efficient which warrants tremendous potential for implementation in the industry.
