Cornell Ithaca Campus heat use data for a model year

Description

Hourly steam use data for all significant buildings from the fiscal year (FY) 2017 (1 July 2016 - 30 June 2017) are provided. The total annual campus heating load in FY 2017 was about 0.81 trillion Btu (283,000 MWth-hrs). The data are presented as a spreadsheet, detailing on an hourly basis the total steam utilized for all buildings in each of three categories of buildings. Also available are conversions of that steam mass to Megawatts-thermal (MWth). For the same hour, the outdoor temperature, relative humidity, and enthalpy values are listed.

53 The data are presented as a spreadsheet, detailing on an hourly basis the total steam utilized for all buildings in each of three categories of buildings. Also available are conversions of that steam mass to Megawatts-thermal (MWth). For the same hour, the outdoor temperature (degrees F), relative humidity, and enthalpy values are listed. The three building categories correspond to the following characteristics: • Type A: Facilities needing high temperature hot water for heat (“High Temperature Facilities”). There are typically buildings with research, teaching laboratories, research plant or animal holdings, or similar facilities that require large make-up air flows. • Type B: Facilities needing “standard” temperature water for heat (“Standard Temperature Facilities”). These include typical teaching spaces, offices, and dormitories not specifically designed for lower temperatures. • Type C: Facilities that do not require temperatures as high as other campus facilities and may be able to utilize “return” water from other building systems to meet their needs (“Low Temperature Facilities”). For most buildings, the data were derived from real-time meters. A small percentage of smaller buildings lack real-time monitoring and for these we have monthly metered data. For those cases, the hour-by-hour usage has been approximated to sum to the known monthly total. https://gdr.openei.org/files/1186/Cornell_Hourly_Steam_Data_FY17%20%28for%20upload%29.xlsx
21 The purpose of this document is to describe the contents contained within Geothermal Data Repository (GDR) node of the National Geothermal Data System (NGDS) that serves as the final report for the project "Earth Source Heat: A Cascaded Systems Approach to DDU of Geothermal Energy on the Cornell Campus". Abstract: Cornell completed a comprehensive evaluation of the potential for Earth Source Heat (ESH), Cornell's specific application of Deep Direct Use (DDU) geothermal energy, to create viable heat energy for its Ithaca, NY campus district heating system. The study included assessment of the natural rock properties within and surrounding two potential reservoirs, coupled to the assessment of the thermal energy needs for a district heating system capable of supplying 20% of Cornell's building heating load. The feasibility and benefits of such a district heating system at the specific location of Cornell University's Ithaca, NY campus are evaluated from the perspectives of economic cost, environmental benefits, and economic benefits in the region external to Cornell University. The economic cost is expressed as the Levelized Cost of Heat, and comparison to the existing inexpensive fossil fuel system. The submission includes descriptions of the assumptions, analyses, data, and models that were combined to reach conclusions regarding the feasibility of a Cornell Campus project. A shortened, descriptive title for the project is "Direct District Heating for the Cornell Campus Utilizing Deep Geothermal Energy." https://gdr.openei.org/submissions/1180
