Building as a Battery

Converting buildings into an efficient energy storage systems to improve energy resilience

Graduate Thesis- Application of Energy Analysis

Advisors : Dana Cupkova (Track-Chair), Vivian Loftness (Co-Advisor), Azadeh Sawyer Kushagra Varma, Sinan Goral

Master in Sustainable Design | Carnegie Mellon University, PA | 2023

Tools: EnergyPlus, IDF editor, HOMER Grid

Increasing number of power outages in the United States have shown vulnerability of the utility grid. To address this issue, there is a growing trend towards stand-alone or building-scale solar panels. However, states like California, known for their high number of rooftop solar panel systems, face challenges due to the diurnal cycle of sunlight. The lack of batteries in existing solar systems affects power production and interrupts critical building functions. A holistic approach integrating PVs, energy storage, and demand control systems can enhance building resilience.

Through simulation analysis, a toolkit of cost-effective, energy-efficient, and environmentally sustainable energy storage solutions was developed. The study led to the development of a scalable and adaptable module to make buildings self-sufficient and support critical loads of other buildings through intentional islanding. It concluded the framework of ‘Building into a Battery’ can help to save the utility grid from DER fluctuations and promote renewable energy adoption for community-based solutions with a focus on equitable social sustainability. The proposed framework, known as ‘Building into a Battery,’ offers a promising pathway to mitigate DER fluctuations, foster renewable energy adoption, and promote equitable social sustainability in community-based solutions.

Research question: How ‘Building as a Battery’ can efficiently manage (generate, store & supply) on-site energy, be energy resilient & serve as an energy hub at a community level during a grid outage?

Research hypothesis: A building-as-a-battery can reduce operational emissions and increase energy resilience for building owners by managing on-site renewable energy systems, while also benefiting the utility grid by reducing fluctuations caused by distributed energy resources.

Scope of research study: The research study focuses on three types of energy load management strategies as below: Distributed Energy Resources (DER), Energy Storage Systems (ESS), and Energy Hubs (EH).

Site analysis based on building typologies in the selected community area of Hazelwood, Pittsburgh, PA

Site Analysis

For the application of the solution set, we have selected a site, which can represent different demographic & socio-economic conditions to minimize the equity & environmental issues with energy resilience. Based on the filters like the number of people under the LMI, category, measures taken for sustainability & energy resilience, access to renewable energy sources, demographic data & cultural data we have selected ‘Hazelwood’. Next, we conducted a simulation study comparing two scenarios for a single building, the ‘Community Kitchen.’

Vacant Buildings Deserted Buildings No Recreational Spaces Dilapidated Buildings

Envelope Assembly & Lighting Power Densities of the building were updated based on Advanced Energy Design Guide (AEDG)

Simulation Study : Scenario-I assumes the building meets min. standards (IECC 2018) and relies solely on the utility grid. Scenario-II optimizes the building’s efficiency using the Advanced Energy Design Guide (AEDG) and incorporates strategies for DER, energy storage, and supports critical loads of 4 other homes. The study establishes a scalable precedent using HOMER Grid & IDF editor as a tool.

Utility Bill Savings

Results from Simulation Study

Comparative analysis of results from simulation study showed $0 savings, no energy resilience, & carbon emission of up to 89,647 kg/yr in Scenario-I.

Where as Scenario-II demonstrated savings in utility bill of $10,425/yr, energy resilience for 3 days, & reduction carbon emission to 78,790kg/yr.

Assessing Policy Support

Lastly the study conducted an extensive review of various policies, grants, tax-credits, and incentives available at the federal, state, and local levels to facilitate the adoption of our proposed design for integrating DER and ESS at the building and community level in our site location. We found that there are currently no policies in the state of Pennsylvania for battery storage.

Pennsylvania can learn from Massachusetts’s SMART Energy Program and improve funding to better enable the community better solutions for energy resilience.

Shaping Daylight Through Simulation and Virtual Reality

Daylight Modeling

Instructor : Azadeh Sawyer

Master in Sustainable Design | Carnegie Mellon University, PA | 2023

Tools: Rhino, Grasshopper, Climate Studio, Enscape & Virtual Reality (VR) technology

Type of Work: Individual

This course aims to delve into the quantities and qualities of light, and how they can be effectively utilized in architectural design through the use of digital design and simulation tools, augmented with virtual reality (VR) technology.

The control and exploitation of daylight is an effective way to reduce the need for electric lighting and improve the overall energy efficiency of a building. The objective of bringing natural light into spaces is not only to support tasks but also to enhance human comfort, wellbeing and building performance.

The course covers design perception, color, vision, lighting techniques, and standards. It provides an in-depth view of how simulation and VR technology can support the design of comfortable and high-performance buildings, enabling students to set various design goals and use simulation and VR to evaluate the impacts of design strategies on targeted performance.

Part 1 (Designing Spaces)

The first part of this assignment is to design two spaces that convey the contrasting feelings/moods, which would have similar light levels. Here I selected two adjectives ‘quiet’ & ‘dynamic’. A skillful arrangement of natural light can create an ambiance of quiet contemplation, whereas its constantly evolving or dynamic nature can bring the liveliness of the space. Formal spaces like libraries give the utmost importance to daylight as it can calm you down, increase your productivity and help you to retrospect. On the flip side, informal spaces like cafeterias continuously tend to change their spatial organization.

The two barrel-vaulted roofs comprise the central skylight and a central reflector brings diffused light & the glazing on the glazing on the East & West facades with operable windows helps natural light & ventilation

The dynamic nature of the cafes is conceptually transformed into the facade of the building creating constantly evolving patterns with the cycle of day & night.

Part 2 (Spatial Daylight Analysis)

In the second part we attempted to reduce the ASE (Annual Sunlight Exposure) to 10% and bring sDA (spatial Daylight Autonomy) between 55-74% or above than the baseline building by performing annual daylight analysis in ClimateStudio and for various design iterations. Additionally keeping the values similar

Part 3 (Glare Analysis)

In this part we aiming to improve the glare performance of the building without disturbing optimum sDA & ASE though spatial & HDR simulations using ClimateStudio. Glare is context-specific, so, we have taken into account factors such as the space program, furniture layout, and views to address glare in areas that may cause discomfort. In the areas where glare is inevitable we have rearranged the furniture and seating arrangement to avoid visual discomfort.

Building Performance Modeling (BPM)

Application of Energy Modeling

Instructor: Wei Liang

Master in Sustainable Design | Carnegie Mellon University, PA | 2023

Tools: eQUEST, IESVE, Design Builder, & EnergyPlus

Type of Work: Team

The BPM course focuses on conceptual foundations and practical applications of advanced and integrated whole-building energy simulation programs with emphasis on architectural building envelope systems, mechanical electrical building systems and their controls (electric lighting and HVAC systems) and building-integrated solar photo voltaic power systems. Building Information Modeling (BIM) concept and its connectivity to Building Energy Modeling (BIM).

The assignment aimed to familiarize me with the IES-VE 2021 software and analyze the energy performance of a specific building design case. By considering factors like site data, building materials, systems, operations, and loads, I gained insights into the synergistic impacts on energy efficiency during the design development phase. For this team project I worked on creating baseline building model, thermal templates & thermal zoning.

20

Several

Baseline Model

Ansys Hall is a six story building located in Pittsburgh, PA. We used EnergyPlus (TMY3) weather data file for energy modeling using IESVE. For construction of our baseline model we selected materials, which are compliant with requirements in the ASHRAE 90.1 2016 for climate zone 5A & created a baseline modeling following the outlines for building envelope, internal gains, & Operational schedules.

Solar shading analysis suggests that the roof and southern facade of the building receive maximum solar energy compared rest of the building.

Solar Shading Analysis

In case of installing PV panels it is important to analyze the shading casted on the building by surrounding objects/vegetation, and energy received on each surface to leverage the maximum energy.

‘Solar shading calculations’ suggests that the roof and southern facade of the building receive maximum solar energy up to 300 - 437.23 kBtu/ ft2. Whereas the western facade receives the least due to adjacent buildings casting shadows.

21
The above image represents the outline used to create the baseline model NW elevation areas of the building are connected to adjacent buildings, making it a complex design to model.

a. Baseline internal load (People, Lighting, Computer (Equipment)) values for each thermal template.

Each space is divided to create HVAC zones by ‘space by space’ zoning method & the entire floor plate at each level is divided into 11 groups based on the geographic directions, interior area, and building cores.

b. Baseline Auxiliary Ventilation Values for each thermal template

Thermal Profile

Based on the types of usage and common thermal comfort requirements, we have created 14 thermal templates for Ansys Hall. Each template has a defined internal loads (refer a) and air exchanges (refer b) according to ASHRAE 62.1 - 2016 addendum for ‘Ventilation for Acceptable Indoor Air Quality’.

The default building office occupancy schedule was used with slight modifications.

Baseline Whole-Building Performance

Compared to median EUI per building type in the U.S., our baseline model for Ansys Hall have a relatively high EUI of 236 kBTU/sf.

Parametric Analysis

Parametric analysis helped to reduce EUI of the building with emphasis on building envelope thermal properties, solar shading, occupancy features, and building geometric properties.

All the key variables decreased during the iterations

Conclusion & Recommendations

To prioritize retrofits and renovations in Ansys Hall, we recommend focusing on increasing insulation for the slab and improving the thermal properties of glazing, if feasible. Following a targeted approach to thermal zoning is recommended. Prioritizing HVAC and lighting upgrades in high-traffic areas such as classrooms and lounges, while implementing energysaving measures like smart sensors in less frequently used spaces like corridors, can yield additional energy efficiency benefits.

Rebrick Lay

A Custom Plug-in for Circular Economy

Application of Computational Design for Sustainability

Instructor: Jinmo Rhee

Scripting & Parametric Design | (MSSD) Carnegie Mellon University | 2022

Tools: Rhino, Grasshopper, & Gh Python

Type of Work: Teamwork with Sanjana Nagaraj

The project goal was to design and develop a custom Grasshopper Plugin, a toolkit that can support complex, repeated, or laborious design processes and helps designers explore diverse design solutions.

For this assignment, we focused on the circular economy. Almost 20% of C & D waste comprises bricks and more than 75% goes to landfills. There are many limitations in reusing these reclaimed bricks, which makes it difficult to use them. Thus, we created a customized plugin using ghPython, which can take the data of these reclaimed bricks and help designers, architects, and engineers to visualize n number of patterns and return an exact number of bricks used from each batch of bricks for it. This can reduce construction waste & encourage a circular economy in the building industry.

28

Algorithm

The algorithm for the plugin is divided into 6 parts from input to output. For input a brick batch parameter will take these parameters to create a 1-D list. Combine data will combine data from these lists to give a 2-D list. Apart from these users must select a wall geometry and an attractor point. These batches will get sorted based on their compressive strengths. Next it will access starting points of each panel, which will get divided in primary and secondary distribution to add bricks based on the given dimensions. At the end it will provide number of remaining bricks from each batch after their use for constructing the wall & create patterns. Users can select their preference through attractor point system.

Waste Management Center,Mumbai

Application of Sustainable Design Startegies

Competition Entry - Asia’s Young Designer Award | 2019

Location: Mulund, Mumbai | Project Type: Industrial & Public

Tools: Revit, Rhino, Grasshopper, Ladybug

Type of Work: Individual

The theme of this competition was to provide a design solution for the ‘Sustainable future’ of our built environment. Considering the exceeding amount of waste and shortage of landfill spaces in Mumbai a waste management center was proposed to replace an existing landfill site.

The program is composed of a waste management area for the segregation of waste, a wasteto-electricity generation plant to produce ‘Clean Electricity’, a cow shed & organic farming, and workshop spaces for community artists, who can create crafts from recyclable waste. Overall building is design with ‘Whole System Thinking‘ approach & aimed to encourage peopel about the ‘Circular Economy‘.

Semi-open spaces such as connecting spaces with openings to frame views, staircases facing central courtyards, and courtyards on the building edges along with rooftop gardens are designed to make spaces interact with nature.

Further it helps to blur the boundary between inside and outside in the public area by creating flexible spaces and opportunities to connect with surrounding landscape.

Sky Dome visualizations for solar radiation mapping over summer solstice time period

We performed solar radiation studies for summer solstice (i.e. 21st June to 21st December) to understand, which sides of the building are receiving more solar radiation.

The incident solar radiation analysis on the building assisting in designing location of fenestrations, glazing areas, shading devices and facade treatment. Further helping to in passive heating strategies by utilizing the thermal radiation, improve indoor thermal comfort & improve energy performance of the building.

The patches on the sky dome with higher solar radiation helped us to find the angle of orientation for the solar panels.

Redefining the Relationship of Humans & their Co-inhabitants through Architecture

Graduate Thesis - Application of Sustainable Design Strategies

Advisors : Swati Chokshi

Undergraduate Thesis | B. Arch | Rachana Sansad’s Academy of Architecture | 2018

Location: Kharghar, Mumbai | Project Type: Public

Tools: Revit, Google Sketchup, AutoCAD

Type of Work: Individual

The aim of this research study was to design a space, where both humans & their co-inhabitants can interact with each other without the solid barrier of a cage, educate people about their surrounding indigenous species & ecosystem and conserve them.

This aim to conserve native flora and fauna and bring humans closer to their co-inhabitants in an urban context led to the proposal of a ‘Zoological Park’. It gives shelter to all the native non-human species struggling to survive in the wildlife due to various industrial or natural issues. The park was designed in such a way as to merge the adjacent mountain ranges of ‘The Western Ghats’ and house hundreds of species native to this tropical ecosystem. It also welcomes visitors, which are immersed in natural life and not vice versa.

The proposal for the zoological park was based on an ‘Ex- situ conservation’ concept, which is part of the ‘Pan-situ conservation’ or ‘Hybrid conservation’ approach. Here animal enrichment is given the highest priority in a way to retain their natural behavior. So, when they are reintroduced back to the wild they can adapt to the environment. The adjacent views shows different architectural and landscape spaces designed to replace the solid barrier of the cage and merge them with the context.
