Project Title:  Large Scale Energy Modeling for Building Energy Rating Standard

Project Description:  Commercial buildings accounts for 20% of the primary energy in the US and there is a great potential to save energy in existing US commercial buildings. To promote energy saving of US commercial buildings, ASHRAE Building Energy Quotient (bEQ) rating standard provides a method to evaluate the energy performance of commercial buildings. ASHRAE bEQ system consists of two sections, As Designed rating and In Operation rating. To support the rating standard, this poster displays our research to perform large scale energy analysis and big data analytics for commercial buildings. The workflow of the research contains four steps: 1) identify possible sensitive model inputs, 2) generate models, 3) conduct large-scale simulation, 4) conduct data analysis, and 5) generate the results. The existing outcomes show that we have already identified and modeled 18 main commercial building types which represent for 85% of floor space, developed the workflow to conduct large scale simulation and data analytics, and conducted the large-scale building energy simulation.  Website: https://www.colorado.edu/lab/sbs/

Project Title: Multi-domain Modeling Framework for Future Smart and Connected Communities

Project Description: Infrastructure in future smart and connected communities (SCCs) is envisioned as interconnected public services, including energy, transportation, and communication systems. While the inherent interdependencies among these critical systems may significantly influence both the design and operation of each system, few prior studies have quantified the potential impacts of these interdependencies. The objective of this work is to develop an open-source, integrated modeling framework for planning, deploying, and operating future communities that are sustainable (zero energy), connected (zero outage and zero congestion), and smart (self-organizing operation). We propose a novel multi-level, multi-layer, multi-agent approach to enable flexible modeling of interconnected infrastructure systems. Various component and system-level models for energy, transportation, and communication systems are designed and implemented using Modelica, an equation-based, object-oriented modeling language. To evaluate the interdependencies and quantify the impacts of integrated modeling, three case studies of gradually increasing complexity are presented (energy, energy + transportation, energy + transportation + communication). Results indicate that the average road velocity during the morning commute decreases 10.5% when the communication system is considered. Similarly, when communication and transportation systems are considered, the power draw from the grid decreases 0.33% on average, with the largest decrease of 7% occurring during the morning commute. These results suggest a need for integrated modeling when designing and operating future SCCs. Furthermore, the proposed modeling framework has the potential to be extended for additional applications, including dynamic modeling and optimization, resilience analysis, and integrated decision making in future connected communities.

Project Title: Irrigation with Produced Water: Impact on Crop and Soil Health

Project participants: Dr. Thomas Borch, Dr. Jens Blotevogel, Dr. Jim Ippolito, Dr. Kelly Wrighton, Kandis Diaz, Dustin Diaz, Rebecca Daly, Hannah Hare, Merritt Logan

Project description:  Oil and gas wastewater, known as produced water (PW), has the potential to be beneficially reused for agricultural irrigation. However, PW can be saline and may contain harmful contaminant concentrations. We irrigated wheat with minimally treated PW to investigate its effects on soil health, wheat growth, and soil microbiome to assess its viability for crop irrigation.  We grew wheat in a sandy loam soil matrix in a greenhouse. The irrigation treatments included control irrigation water, 1% and 5% PW dilutions, and a salt water control with equivalent salinity to the 5% PW dilution. During wheat growth, we measured plant physiological parameters, soil electrical conductivity, chlorophyll fluorescence, and collected soil samples for 16S rRNA soil microbial community analysis. Final soil quality parameters were measured after harvest, including: bulk density, microbial biomass, potential mineralizable nitrogen, soil potassium and phosphorus, and total organic carbon and nitrogen. PW treatments did not alter wheat height and chlorophyll measurements; however, both the salinity control and 5% PW treatment had reduced yields as compared to the control. Measures of microbial soil activity were lower in 5% PW treatments as compared to all other treatments. Soil concentrations of phosphorus, potassium, and inorganic carbon were not significantly affected by PW irrigation. In conclusion, watering crops with minimally treated dilutions of PW may result in yield decreases and negatively affect soil health parameters but is dependent on the PW composition. Future large-scale field studies are needed to determine the long-term effects of PW on different soil types and crops.

Project Title: Technical-economic Analysis of Photovoltaic based Distributed Generation Systems for the Mexican Industrial Sector.

Project description:  The Mexican industrial sector represents an important part of the national consumption of electricity (30%) and during the last 10 years it has maintained a constant annual growth average annual growth rate of 5.8%. At the end of 2016 this sector concentrated 9.8% of the nation’s energy users. All these facts mean that ensuring the supply of electricity for the industrial sector is of great importance, both in terms of availability and quality of service.  Distributed generation refers to a variety of technologies that generate electricity at or near where it will be used. Currently there are 3 schemes that apply to Distributed Generation (Facilities with installed capacity less than 500 kW) in Mexico: Net Metering, Net Billing and Total Sale.  With the objective of evaluating the potential and viability of PV systems to the industrial sector, the most relevant economic indicators in the analysis of energy projects are calculated (Internal Rate of Return (IRR), Recovery Time (Payback), Net Present Value (NPV), Cost – Benefit (C/B) factor). These indicators are calculated for several proposed PV systems and then they are used to compare the costs of consumption of electricity over 20 years in two scenarios: i) with a PV system, ii) without a PV system. This cost over time is estimated calculating and analyzing the Levelized Cost of Energy (LCOE).  The present study focuses on evaluating the economic aspects regarding the integration of PV systems to the industrial sector under the new schemes of Distributed Generation by using the software System Advisor Model (SAM), developed by the National Department of Renewable Energy (NREL).  The cities evaluated in Mexico are the capitals of the 32 states and are selected according to their population as well as the industry concentration.

Project Title: Improving Data Center Energy Efficiency through End-to-End Cooling Modeling and Optimization (Sponsor: U.S. Department of Energy, Award Number: DE-EE0007688)

Project Participants: University of Colorado Boulder (Xu Han, Wangda Zuo, Yangyang Fu), Lawrence Berkeley National Laboratory (Michael Wetter), Schneider Electric (Wei Tian, Jim VanGilder)

Project description:  Data centers in the US consume about 2% of the nation’s electricity and approximately half of that is used for data center cooling. To improve energy efficiency of the cooling system in data centers, many researches have been focusing on either the cooling system or the airflow management in the data center rooms. The separation of cooling system and airflow management leads to local optimum design and operation. The integration of the cooling system operation and airflow management will provide a holistic solution to the optimal operation of the data centers.  The goal is to develop and demonstrate an open-source, modular, free software which provides practical, end-to-end modeling and optimization for data center cooling for use by data center designers, service consultants and facility managers, as well as for integration by data center management software companies. The tool box includes three features: (1) Feature 1: optimization of cooling system operation; (2) Feature 2: optimization of airflow management; (3) Feature 3: simultaneous optimization of airflow management and cooling systems. We have developed the modeling packages of the cooling system and airflow management of data centers, which have been publicly released. Currently, we are working on integrated modeling of the cooling system and airflow management to conduct a holistic solution to the optimal operation of the data centers.  Lab website: http://www.colorado.edu/lab/sbs

Project Title: Water Agriculture Food Energy Research Nexus (WAFERx)

Project Participants (PI and co-PIs): Paul Story (Montana State University), Selena Ahmed (Montana State University), David Swanson (University of South Dakota), Meghann Jarchow (University of South Dakota), Ben Rashford (University of Wyoming)

Project Description: The Water Agriculture Food Energy Research Nexus (WAFERx) is a research collaborative studying the implications of adopting Bioenergy with Carbon Capture and Storage (BECCS) as a form of climate change mitigation.  BECCS reduces atmospheric CO2 first through the production of bioenergy crops, which absorb CO2 from the air during photosynthesis. The CO2 emitted when these crops are converted into energy is then captured and injected into geologic formations underground for permanent storage. This results in what is referred to as ‘negative emissions’—meaning more CO2 is removed from the atmosphere than is released.  BECCS, while potentially reducing atmospheric CO2, would also require transformations in agriculture, land-use, and energy production systems, creating trade-offs among food, water, energy, biodiversity, and economic opportunities. For example, bioenergy crops could displace food crops, threatening local food security. CCS practices and bioenergy production could require changes in water use, affecting water quality and quantity. Grasslands, wetlands, and forests could be converted to intensive bioenergy crops, altering wildlife habitat and biodiversity. These land-use conversions could also cause the release of large amounts of CO2 currently stored in native ecosystems, incurring a carbon debt so large it could take generations for BECCS to repay it. Transitions from fossil fuels to bioenergy industries could impact employment opportunities and local and state tax revenue, affecting regional economic development. The WAFERx team is evaluating the implications of these potential trade-offs for the local people, communities, cultures, and ecosystems of the Upper Missouri River Basin.  WAFERx Outreach Resourceshttps://drive.google.com/drive/folders/1-P4rOj_uukNkmILJT7ZBnmmTRaLvSVA6?ogsrc=32

Project Description:  Produced water (PW) is the largest waste stream associated with oil and gas operations. This complex fluid contains petroleum hydrocarbons, heavy metals, salts, naturally occurring radioactive (NORMs) and any remaining drilling, stimulation or well maintenance chemicals, as well as their potential transformation products. In the United States, west of the 98th meridian, the federal National Pollutant Discharge Elimination System (NPDES) exemption allows release of PW for agricultural beneficial reuse. Contents and concentrations of chemicals in PW vary by location and time. As a result, treatment strategies vary, and PW NPDES releases are poorly characterized.  The goal of this study is to characterize potential environmental impacts and toxicity of PW discharges on downstream water quality. Water samples were collected from three NPDES PW discharges and surrounding watersheds in a Wyoming oil field. Engineered wetlands were located downstream of each discharge. Thus, the efficiency of using wetlands for onsite treatment of PW was also assessed. PW discharge streams were characterized using chemical analyses and toxicological bioassays. Contaminants including benzene, NORMS and surfactants were identified at elevated concentrations at the NPDES discharges. Concentrations of these chemicals generally decreased with increasing distance from the discharge. Hydrophilic compounds, including surfactants, were significantly attenuated in the wetlands. Mutation bioassays revealed higher chronic toxicity at the discharge than implied by chemical analysis, showing that bioassays are a useful tool for assessing complex water quality. The results of this study can be used to help industry and regulators effectively and safely manage PW discharges for agricultural beneficial reuse.

Project Title:  Economic and Environmental Impact Assessments of Drought-Tolerant Crops in the American Southwest

Project Participants:  Hailey M. Summers, Sproul, E., Johnson, J., Jason C. Quinn

Project Description:  Guar (Cyamopsis tetragonoloba L.) and Guayule (Parthenium argentatum) are drought-tolerant crops that produce high-valued products, guar gum and rubber, respectively. Guar gum demand in the last decade has exponentially increased due to its use in fracking of shale oil and gas. Guayule has recently gained interest as a replacement for rubber in tire manufacturing. Current demand for both crops is primarily met through costly U.S. import. However, minimal work assessing the economic and environmental feasibility of domestic production of guar gum and rubber has been performed. The approach to quantifying economic and environmental impacts for Guar and Guayule has been divided into two steps. First, detailed process models capturing mass and energy requirements for domestic production of guar gum and rubber were developed. Second, economic and environmental data associated with the mass and energy requirements was integrated to perform techno-economic and life cycle impact assessments. Preliminary assessment results were focused on determining areas of high cost and large environmental impact from each crop. It was determined that irrigation and downstream process heating, through natural gas, have a large impact on both economics and the environment for both crops. Additional significant areas of impact were observed from downstream processing stages, namely spray drying for guar gum and solvent extraction for Guayule. Ongoing work is focused on expanding modeling scope, such as including use and end-of-life phases as well as co-products, to perform a complete life cycle assessment. Final assessment results will be compared to current crops cultivated in the American Southwest.

Project Title:  Stochastic Home Energy Management Systems with Varying Controllable Resources

Project Participants: Kaitlyn Garifi, Kyri Baker (University of Colorado Boulder), Dane Christensen (National Renewable Energy Laboratory), Behrouz Touri (University of California San Diego)

Project Description:  This project studies the performance of a model predictive control (MPC) algorithm in a home energy management system (HEMS) as the set of controllable resources varies and under both a constant and a time-of-use (TOU) electricity price structure. The set of controllable resources includes residentially-owned photovoltaic (PV) panels, a home battery system (HBS), an electric vehicle (EV), and a home heating, ventilation, and air conditioning (HVAC) system. The HEMS optimally schedules the set of controllable resources given user preferences such as indoor thermal comfort and electricity cost sensitivity. The home energy management system is built on a chance constrained, MPC-based algorithm, where the chance constraint ensures the indoor thermal comfort is satisfied with a high probability given uncertainty in the outdoor temperature and solar irradiance forecasts. Simulation results for varying sets of controllable resources under two different electricity price structures demonstrate the variation in the HEMS control with respect to HBS operation, electricity cost, and grid power usage.
