Focus: Evaluation of 3 green data centers large elements – building conservation
Although the green data center industry has no uniform evaluation criteria, but we can Building energy efficiency , Operations management, Energy Efficiency and so on to measure whether a data center "green."
Needs to be emphasized is that the green data center Energy Effect is like a long tail curve, its front groups, usually building energy consumption, server energy consumption, air conditioning energy consumption, UPS and energy consumption of "big targets" composed of the tail of the curve by the air flow design, equipment placement , the distance between the cabinet and server, maintaining the degree of difficulty many "small target" component. If there is no overall design ideas and implementation methods, even to seize all the "big targets", it is difficult to achieve the desired effect of green energy.
Elements of building energy efficiency Building energy saving elements include: Construction site location: urban development, the geological environment, climate, air quality, power supply, stormwater management and utilization, such as landscape design and reduce the heat island effect.
Thermal performance of building envelope: shape factor, window and wall area ratio, heat transfer coefficient, thermal bridge envelope internal surface temperature and thermal defect, external shading devices, shading performance, external envelope performance, visible light transmittance of glass, transparent building envelope air tightness, etc..
Mining HVAC Air conditioning and hot water supply system: the indoor temperature, humidity, fresh air, chiller efficiency, boiler efficiency, unit air volume fan power consumption, the main branch loop return water temperature is consistent, fresh air, cold water chiller for return water temperature, water systems supply water rates, energy recovery efficiency.
Distribution systems: power distribution system capacity, electric power quality.
Lighting: Lighting Lighting The value of the efficiency and illumination, lighting power density value, the public area lighting control. Energy Monitoring and Control System
Diagnosis: control and its reliability, validity, central management system data storage, classification, export and other energy related with the analysis.
Comprehensive diagnosis: data center energy consumption and changes in the law; analysis of composition and the proportion of energy consumption; for Energy Used to analyze the problems and key factors, proposed content and method of energy saving; for energy-saving technical and economic analysis.
Water use: landscape water conservation, use of innovative wastewater treatment technology to reduce water consumption and water conservation, etc..
Building energy efficiency and atmospheric: the basic building systems commissioning, minimum energy characteristics of HVAC equipment to eliminate CFC use, optimize energy characteristics, renewable energy, commissioning and trial operation, monitoring and control, green energy utilization.
Materials and resources: renewable resources, collecting, building reuse, construction waste management, use of recycled materials, local / regional materials, rapidly renewable material use, use of sustainable development materials.
Indoor environmental quality: carbon dioxide monitoring, increased ventilation efficiency, indoor air quality, construction management, use of low-emission materials, indoor chemical and pollutant source control, the system can be controlled, thermal comfort, natural light and visual environment.
Elements of Operations Management Operations management elements include: Operations management maturity: service planning and implementation, service level management, service reports management, service continuity management, availability management, IT Service budget and financial management, capacity management, information security management, business relationship management, supply-side management, event management, issue management, configuration management, Change Management, release management.
Sustainable improvement of operational management capabilities include: information security management capabilities and service quality management capabilities.
Energy efficiency factor PUE value: IT equipment, infrastructure, power consumption and power consumption.
IT Equipment Energy Efficiency Ratio: IT Equipment Power supply Efficiency.
