Contracting method

General Contractor

Owner approach of sustainability

As a specific type of public building, hospitals have the characteristic of complex functional layout, complex people, owing many large-scale applications, complex energy consumption systems and continuing to work throughout the year. As a result, hospital buildings require more energy than other public buildings and have a large potential of energy conservation. Hence, it is of great significance for hospital buildings to improve energy management and energy efficiency.
Energy performance contracting method was introduced into the renovation of recovery system of boiler smoke, solar heating water system and intelligent management system to improve enhance the performance of energy management.
As a result of the comprehensive renovation of the hospital, space is reasonable used, waiting areas for visitors are more comfortable, energy consumption was reduced, visual environment of patients was improved.

Architectural description

The intelligent management system realizes digital centralized monitoring and data acquisition of energy consumption.
Energy conservation of external was realized by controlling the window-wall ratio, reducing heat transfer rate of widows, improving shading coefficient and strengthening air tightness.
The hospital has revisited its wastewater treatment system and expanded its capacity to supply water for green area irrigation, garbage flush and so on. Outlet pipes were connected to the pipes of outdoor green areas to ensure the quality of water during supplying.
Under the circumstance of existing underground space, the hospital realized reasonable land using by considering the harmony of environment and hospital area. Two roof greening were applied to form a composite green area in harmony with other grassland in the hospital area.

If you had to do it again?

Oil boiler was replaced by oil & gas boiler in this project. During the process of purchase, storage, energy conversion, distribution and terminal consumption, normal rate of energy loss is 3~5%、8~12%、3~7%, respectively. In other word, by using gas boiler, the rate of energy consumption is expected to be 13.44%~22.25% and the cost of heating supply is expected to be 0.2403~0.2675yuan/MJ. As a result, cost of heating supply was decreased by 10% after the renovation of valves.

Energy consumption

• Primary energy need : 203,41 kWhpe/m².年
• Primary energy need for standard building : 317,53 kWhpe/m².年

Calculation method : Experimental calculation method (China)

• Initial consumption : 96,22 kWhpe/m².年

Envelope performance

• Envelope U-Value : 0,50 W.m^-2.K^-1
More information :

Energy conservation of external was realized by controlling the window-wall ratio, reducing heat transfer rate of widows, improving shading coefficient and strengthening air tightness. In this project, single glazed windows of inpatient building were replaced by hollow double glazing windows to reduce heat transfer through the external window. According to the design and calculation description, heat transfer of the external wall and external window is 0.50W/(m2•K), and 2.9W/(m2•K),, respectively.

• Building Compactness Coefficient : 0,24

Indicator : GB/T 7106-2008

• Renewable energy production : 31,58 ％

Energy conservation of 2nd building was realized by applying solar heating water system and reducing the heat requirements of heat transfer machine room. Based on the automation control of water flow, measurement of temperature and flow mass, applying temperature sensor in heating water storage tank and heat collector, the total area of solar hot water system collector is calculated to be about 383.4 m2.

Solutions enhancing nature free gains :

Single glazed windows of inpatient building were replaced by hollow double glazing windows.

Smart Building

BMS :

Intelligent management system was introduced into this project covering major functional buildings in this hospital, having an area of 64,521 m2. The management system is composed of air conditioning system, electro-metering, public lighting, boiler system, monitor of water-collecting well, domestic water system, monitor of elevator. The system can not only realize real-time monitoring but also can realize failure warning.

Users’ opinion on the Smart Building functions : Entirely management system is applied in this project to make hospital’s service system convenient and effective.

Urban environment

The area of green space is increased by using composite green floor. Grass brick, water drainage brick and other materials are applied to the parking space to satisfy the road requirement of strength and duration. Also, in this way, rain water can permeate to the underground soil directly.

Land plot area

Land plot area : 1 615,00 m²

Green space

Green space : 8 317,90

Parking spaces

The hospital has 38 parking spaces, including 5 barrier-free spaces. There are 184 double-layer mechanical parking spaces located on the 1st underground.
