- Utilities planning is important for campus master planning to address health and safety issues, efficiently support facilities, and impact costs of projects.
- Key utility considerations include assessing electrical power sources and capacities, proximity to heating/cooling plants, and sizing infrastructure for future growth.
- ISU's 2000 master plan improved infrastructure, expanded district cooling, and reduced energy use and costs through various upgrades and an energy services contract.
- Failure to comprehensively plan utilities results in piecemeal, expensive, and inefficient systems that require redesign with each new construction phase.
- Strategies for the current master plan include continued interconnectivity of heating/cooling, addressing infrastructure along Gregory Street, pursuing more reliability/efficiency projects

It discussed both the incredible energy and dollar savings while also addresses the importance of the project team and their importance in delivering what was a truly great project.
Thermal Potential in the Built EnvironmentYale Carden
HVAC systems have traditionally used the local ambient air (heating and cooling) or fossil fuels (predominantly heating through combustion) as their heat source and heat sink. Thermal storage is still a relatively new application and typically requires large volumes of water or ice.
This paper explores the available thermal potential within the built environment and how the utilisation of this thermal potential can provide efficient heating, cooling and hot water as well as thermal storage. In some instances, this may be the local ambient air, less likely it will be fossil fuels.
More likely, it includes the thermal potential within the ground, water bodies and infrastructure such as subways, water, sewer, building foundations and other buildings as well as artificial thermal storage such as phase change materials.
The key is to identify the optimal thermal sources, sinks and storages for a given building at a given location and climate. Then, an integrated approach using optimised control strategies, including predictive capabilities, will enable a building to access these various thermal sources at the thermally optimal time to provide significant energy savings and enhanced operation.
Such an integrated approach also maximises the availability of on-site renewable power generation, further increasing energy savings, decreasing the typical cooling peak demand and increasing energy productivity.
Geoexchange and Thermal Potential at GeoscienceYale Carden

or GSHP systems in Australia. Now over 20 years old, the building recently hosted an information session on electrification of heating and cooling in the ACT. Speakers included ACT Government representative as well as this presentation on thermal potential and the role of renewable thermal energy in the removal of thermal gas from our buildings.
Using the Ground for Thermal Energy Storage: The Experience of the Riverina H...Yale Carden
All buildings interact with the ground for its ability to support their foundations. However, very few buildings interact with the ground for its ability to provide thermal energy storage. We have all experienced the moderate temperatures within a cave at depths of just a few metres. These temperatures are a function of average annual air temperature and are the result of the ground absorbing and storing solar energy. The use of this indirect and renewable solar energy can provide significant energy savings for heating and cooling systems.
A Ground Heat Exchanger (GHX) provides the ability to utilise the ground for thermal energy storage, essentially transforming the ground into a thermal battery. It enables us to extract heat from it in winter (heat source) and return that heat in summer (heat sink). It is a dynamic thermal battery that operates both simultaneously and over the annual heating / cooling cycle.
This presentation will provide an overview of how the ground is being utilised for its thermal energy storage capabilities around the world, with focus on a local installation at the Tumut Council owned Riverina Highlands Building, located in Tumut NSW. The installation has provided Council with energy savings on heating and cooling of 80 %, reduced peak energy loads by 40%, reduced maintenance costs and, importantly, provided significantly higher levels of occupant comfort. This has also increased the capacity and effectiveness of the concurrently installed solar PV array and will ensure that future solar energy storage will have greater impact.
The Role of Thermal Potential in Enhancing Energy ProductivityYale Carden
As presented at All Energy Conference in Melbourne on 5 October 2016
In the renewable energy sector, electrical (energy) potential determines the design of renewable power systems (ie solar, wind etc) at any given location. Similarly, thermal (energy) potential relates to the available thermal energy in a given location that can be utilised for heating / cooling a building or group of buildings.
This presentation explores how the concept of thermal potential can increase the efficiency of heating / cooling systems and thus enhance energy productivity in terms of increased value output per kW generated and per tonne of carbon emitted.

A printed circuit board (PCB) is a fundamental component in modern electronics that serves as a platform for assembling and connecting electronic components. It provides a solid foundation for the interconnection of various electronic elements, including integrated circuits (ICs), resistors, capacitors, and other passive and active components.
The construction of a PCB typically involves a thin board made of non-conductive material, often fiberglass reinforced with epoxy resin or other laminates. The surface of the board is coated with a layer of copper, which serves as the conductive material for the electrical pathways.
PCB design involves a meticulous layout of conductive traces, which form the pathways for electrical signals to flow between components. These traces are usually etched onto the copper layer through a process of chemical etching or mechanical milling. The layout of the traces is determined by the circuit schematic, aiming to minimize signal interference, optimize signal integrity, and ensure efficient electrical connectivity.
In addition to the conductive traces, a PCB features various other elements. These include pads and vias. Pads are small areas of exposed copper where electronic components are soldered onto the board. Vias are holes drilled through the board that connect different layers of the PCB, facilitating the routing of traces between them.
PCBs can have multiple layers, ranging from single-sided boards with components mounted on one side, to double-sided and multi-layer boards, which have components mounted on both sides and multiple layers of conductive traces sandwiched between insulating layers.
The manufacturing process for PCBs involves several steps, including design and layout, fabrication of the board itself, application of the copper layer, etching or milling of the traces, drilling of holes for components and vias, and finally, assembly of components onto the board through soldering or other methods.
PCBs are essential in a wide range of electronic devices, from simple consumer electronics like calculators and remote controls to complex systems like computers, smartphones, and medical equipment. Their compact design, reliability, and scalability make them indispensable in the world of modern electronics, enabling the creation of increasingly sophisticated and efficient electronic devices.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Editor's Notes
Examples of #2: you cannot plan a major remodel project without considering Utilities Infrastructure. In fact our experiences with SCH, STV/TUR, Res. Halls and CDS projects all involved significant mechanical issues. #3: The same applies to new construction COB tunnel for steam and CW, placement of SF&KR impacted the capacity of the Quad chiller and required the S. Plant project to be initiated. Gregory St. will require all new sources of power, heating, and cooling. CFA is a case where all utilities are in place and only minimal utility infrastructure improvements will be necessary.
These are some of the Utility Infrastructure issues Master Planners will need to consider in both the case of new construction and facility upgrades.
This plan has been the Bible for virtually every utility decision made in the past 8 years. As you can see by the condition, it has been either on my desk or in my notebook the entire time. The good news is as you go down the Table of Contents you can see we have completed or made substantial progress in all of the areas. Lighting Upgrades: thanks to almost $900,000 in grants from Il Clean Energy Foundation we have been able to perform T12/Elec ballast upgrades in every building on campus. Every year since 2002 energy savings from the utility budget have been reinvested in not only lighting, but also boiler upgrades, insulation, and steam trap replacement. These are the “low hanging” fruit of the energy conservation projects. District cooling and the installation of 4 boiler economizers have been the primary infrastructure improvements since 2002. In the area of Procurement, the most significant event was the deregulation of the electrical market in 2007. ISU took the leadership role and joined with 4 other state univ (EIU, SIU/SIUE, WIU) to combine our loads and profiles and a joint RFP process to guarantee us favorable rates. Let me walk you through the District cooling progress we have made since 2002.
This is the status of chiller water units in 2001. As you can see most every building had its own chiller unit, and most of these were in marginal or high risk condition. There were no redundant systems, if a chiller broke, the facility went without AC until a repair or replacement was made. The yellow sites mark the beginning of District cooling on our campus. A large chiller was purchased with the construction of CPA and was installed in the HP. Subsequently, the chillers in Cook, Edw, and FC, MET failed and those facilities became the first buildings on the Quad district loop.
Funds from both the COB and SCH projects were used to purchase the second Chiller & Tower and were also installed in the HP. You can see the list of buildings that have been added to the Quad loop as a result of this plan. Left to be added are CE/CW, OU, the remainder of Wms, and FEL. BSC was build with two large redundant chillers. So rather than replace the chiller in Milner, BSC was made into a “notional chiller plant” and now serves BSC, Braden, Milner, and Bowling-Billiards center. Does anyone know where our second “Notional Chiller Plant” is Located?
E. Campus chiller failed. UHS had $1.5M project planned. But…SLB was built with 2 chillers with double capacity so SLB became the NE chiller plant. Soon after, the remainder of the 5 chillers in the CRP failed or were expensive to maintain, so the CRP was scrapped and all of those buildings were added to the NE Loop.
These two chiller plants were constructed simultaneously and opened during the summer of 2008. Next season Linkins DC will be added to the SE Loop and Turner Hall will be added to the NW loop this summer with N/S to follow when its current chiller starts to show signs of old age. With two season under their belts, both of these plants are operating with far less that their anticipated loads which is indicative of even greater efficiencies that used in the design.
The last of the planned chiller loops is the South plant currently under construction to primarily support the SF&KR facility. In addition it will take some of the load off of the Quad chiller system by also cooling COB and FEL immediately, and eventually will extend to Coll of Fine Arts.
Now that these loops are nearly complete, the next goal will be to start incorporating some inter-connectivity between the loops. SW-SLB-SE-South could all be linked. This will significantly increase reliability, redundancy, and will give us the opportunity to exercise some fuel flexibility between the gas chillers in the Quad loop and the electric chillers in the satellite plants.
Might want to mention the Utility issue at U of I as an example of failure to Master Plan.
