工程
The primary services and responsibilities of the 工程 department include management and implementation of the university's infrastructure projects, 翻新现有设施, oversight of the university's master plan and support for construction of new high performance green buildings including the LEED Platinum certified Human Health Building and LEED Gold certified 工程 Center, Hillcrest大厅, 和橡树景厅. 除了, 我们监督学校的雨水管理项目, 工程设计文件, purchase of utilities and implementation of a variety of energy initiatives. 我们还对校园的资本资产数据库进行管理, continuously promoting initiatives for sustainability best practices and green culture within the campus community.
Take a look at the historical usage and cost of the west campus utilities over the past decade. 而 生活用水和下水道的使用都保持相对平稳 electric and natural gas usage has steadily increased in step with our campus growth. Please note that more updated figures are now available in the latter pages of the above Annual 能源 Reports.
每名全日制等效学生每年大约花费380美元. This equates to 4% of full time student's tuition (based on 15 credit hours for two semesters). 截至2010财年，每平方英尺成本约为2美元.每年50.
我们需要你的帮助! A significant amount of 电 is used during the night time and weekend hours. The University maintains at least 2 megawatts of electrical consumption throughout evenings and weekends. 每个尖峰代表一天. The spikes are grouped a weekly pattern of five high usage days and two weekend days.
我们夏天的用电高峰是7点多一点.5兆瓦.
A significant portion of this off-peak usage comes from equipment that is not turned off! 灯、电脑显示器、电脑、打印机、复印机等... 晚上是否应该全部关闭以延长其使用寿命, 节约能源, 并减少对环境的污染.
天然气: 韦德体育app官网 purchases its natural gas on the wholesale market from various suppliers. The wholesaler then delivers the gas to our local distribution company (消费者的能源), who then delivers it to our door via one gas meter located at the Central Heating Plant. 查看过去天然气批发价格, look at the monthly New York Mercantile Exchange prices for natural gas contacts originating from Henry Hub. Henry Hub is a pipeline hub in Louisiana and is the reference delivery point for all U.S. 天然气期货合约. 查看纽约商品交易所天然气的实时定价. 交易在工作日上午10点开始.
电力: In 2002, 韦德体育app官网 entered into a two year contract to purchase 电 under our State's 电 Choice program. The University saved approximately $500,000 in FY03 and $380,000 in FY04 on the program. 这种情况与天然气采购计划几乎相同. An alternative electrical supplier delivers our required 电 to our local distribution company (底特律爱迪生), 然后谁把它送到我们在南变电站的开关柜. 合同已经完成了, and we are monitoring market conditions and regulatory issues to see if a second contract will be favorable.
水: The west campus receives its domestic water supply from the City of 奥本山 via three meters. 我们校园的水管把三条水管连在一起, 形成冗余的传递路径. 东校区的水源来自罗彻斯特山市.
单独计量的建筑物: Numerous smaller buildings on the east and west campuses are individually metered for gas, 电, 和直接从消费者协会获得的水, 底特律爱迪生, 和罗切斯特山. The cost of these individually metered locations is approximately 1% of our annual utility purchases. Several of the east campus 辅助 units purchase their own gas and power.
由韦德体育app官网计算、能源管理
韦德体育app官网 设施管理 purchases utilities from 底特律爱迪生, 消费者的能源, 奥本山, 罗彻斯特山, 以及其他不同的供应商. All but a few campus buildings are submetered so that utility usage is know building by building. 一个部门只占用大楼的一部分, 估价是按平方英尺的百分比计算的.
Below is an overview of the utilities supplied by 设施管理 to the various Auxiliary Departments. 其他的则由个别辅助部门直接支付.

A Cogeneration system is also called a Combined Heat and Power; it consists of a turbine generator that burns natural gas which produces electrical power and waste exhaust. 废气被回收并转化为热水.
This system produces electric and thermal energy from a single source of fuel and consumes the natural gas in the turbine to generate 电 and recoverable heat from the exhaust air stream. 排气流, 大约950华氏度, is ducted into the Waste Heat Recovery Unit (WHRU) to produce high temperature hot water.
The hot water is then sent out to the campus buildings via the hot water piping distribution system. 热水用来给建筑物供暖, 供家庭热水使用, 也可以用吸收式冷却器进行冷却.
When the University’s heating requirement exceeds the recovered energy from the exhaust, a supplemental duct burner in the WHRU provides additional heating at 90% efficiency.
When the University’s heating load is less than the recovered energy from the exhaust, the diverter bypass damper located in the WHRU releases the excess exhaust heat.
