Event: International Green Building Conference (IGBC) 2014
Speaker: Stephen Selkowitz, Group Leader, Windows and Building Envelope Materials Group & Senior Advisor, Building Technologies and Urban Systems Department, Lawrence Berkeley National Laboratory
Synopsis:
Enhancing building performance is a central feature of Singapore’s quest for a green building future and this need is echoed across the planet. Global climate change, resource challenges and environmental quality are urgent motivations for transforming the patterns and practices of energy use in the building sector.
This is reinforced with the growing interest in enhancing the indoor environment of buildings to enhance health, comfort and performance, and in tying the operation and performance of buildings more intimately to the electric grid that supplies them. A plausible set of questions to ask in terms of building performance is “What performance goals should we achieve?” and “How are we going to get there?” We explore the answers to these questions through the perspective of recent experience in the U.S. and try to understand the similarities and differences in experience between Europe, Asia and the U.S. Two key perspectives are explored: 1) the degree to which new technologies, integrated systems and human-centered design practice allows us to approach the vision of Zero Energy Buildings and 2) the gap that remains between what has been achieved as proof-of-concept and by innovative teams vs. what has proven feasible to rapidly scale.

The goal of this discussion is to demystify building performance modeling. Computer-simulations give you a more complete picture of how various context and design factors can affect the performance of your space. Modeling information can help you analyze the impacts of your design decisions and determine how to most effectively meet project goals.
Energy modeling is also valuable tool used for code compliance and LEED points. Not to mention the fancy graphics that models produce to show your clientele your commitment to performance-based design.
This discussion will present various opportunities that can arise from building performance simulations with analysis at the early design, whole building, and building component levels. We will examine the following types of analysis:
• Climate
• Daylighting
• Massing and orientation
• Whole building energy usage forecast
• Fenestration design
• Façade development
• Zone level energy performance
• Baseline and design case models
• System selection and optimization
For more information on this training, contact Brittany Grech at bgrech@yrgsustainability.com or (347) 843-3085.
This talk, given at Google on June 6, 2012, summarizes what we know about energy use and information technology in a clear and understandable way. The person preceding me on stage was former Vice President Al Gore, so the pressure was on! I think I delivered, but you be the judge.
Building simulation is the process of using a computer to build a virtual replica of a building.
The building is built from its component parts on a computer and a simulation is performed by taking that building through the weather conditions of an entire year.
In a way, building simulation is a way to quantitatively predict the future and thus has considerable value.
Building simulation is commonly divided into two categories:
Load Design,
Energy-Analysis.
The common phrase for building simulation when energy is involved is Energy-Simulation.
The latest IES Faculty event took place in London on 24th September, 2014. The seminar, which was part of World Green Building Week, focused on the issue of the Performance Gap, with our aim being to engage and work with the industry to diminish the difference between the expected and actual energy performance of buildings.
In this deck from the 2018 Rice Oil & Gas Conference, Doug Kothe from ORNL provides an update on the Exascale Computing Project.
“The quest to develop a capable exascale ecosystem is a monumental effort that requires the collaboration of government, academia, and industry. Achieving exascale will have profound effects on the American people and the world—improving the nation’s economic competitiveness, advancing scientific discovery, and strengthening our national security.”

Building Energy Simulation project by using eQuestAsadullah Malik
The energy shortage crisis and the rapid change of global climate have become important issues in the world now a days since modern trends are shifting to more sustainable solutions to save energy and to reduce the emission of carbon dioxide. Generally speaking, when improving energy efficiency and adopting the energy –saving design, the advantage is not only providing low operating cost for stakeholders, but also reducing the negative impact on the global and ambient environment. This study analyzes the surveyed building integral energy consumption, evaluates its energy performance, and gives further recommendations for saving energy costs by using dynamic energy simulation tool eQuest.

In my system we have to make a system by which a user can record all events coordinated by a particular faculty. In our proposed system some more featured are added which differs it from the existing system such as security.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

Addressing the Building “Grand Challenge”
• Focus on Life Cycle of the Building
– Design Construction Operations Renovation Decommissioning
• Focus on Measurable, Documented Energy Impacts
– Make performance visible, understandable, actionable
• Focus on Integrated Smart Building Systems
– Materials Devices Integrated Systems Buildings
• Focus on Buildings and the Grid
– Renewables, Storage, Microgrids, Neighborhoods, “Smart Grid”
• Focus on People and Behavior
– Policy makers, Designers, Investors, Contractors, Occupants,..
– Occupant behavior, life style, satisfaction, comfort,….
• Focus on “Intersection” of Technology and Policy
– Incremental + Innovative, Disruptive technologies
– Investment and Decision making
13. Lawrence Berkeley National Laboratory
Significant Impact Comes Only from
Comprehensive Balanced Program
To routinely deliver high performance, low-energy buildings
we must find a balance between:
Technology
Process
Solutions fail without this balance
Markets
Economics
Policy
People
Innovation
14. Lawrence Berkeley National Laboratory
•Increase Rate of Adoption of Existing/Emerging Technologies
– Operational improvements
– Better Design and Selection Guidance
– New Market channels
– New Voluntary and Mandatory Programs
– Education: best use for a particular application (climate, etc.)
•Create Pipeline of New Technology Options and Business Models:
– Incremental improvements to technology available today
- Performance enhancements but Cost reductions
- New features
– Breakthrough R&D
- Innovation- new products, new applications
– Components Integrated Systems
– “Net Zero Buildings” – Efficiency + Energy Generation
“Do It Now” vs “Wait and Do It Better Tomorrow”
Why Not Do Both!
15. Lawrence Berkeley National Laboratory
A Framework for Building Performance
1. Predict Performance: Use fully validated simulation
models and processes to reliably simulate and
optimize a wide range of systems and their
interactions.
2. Ensure Actual Performance: Validate/integrate
simulation with measurements in testbeds and real
buildings.
3. Deploy at Scale: Implement performance prediction
tools and smart operations in routine practice
Vision: To design and operate buildings with “guaranteed”
energy performance.
Goal: To accurately predict and verify energy performance
across the building life cycle, from design to operations

“guaranteed” Energy Performance
• Can a Design Team Guarantee Energy Use target?
• Design – Bid – Build – Operate….??
• Need new metrics and new business practices
• New Market Drivers:
• Outcome-based codes:
– “Build anything you want but prove that the building
energy use is lower than target level after occupancy…”

The “Headlines” from
The New York Times Building
• 2003: Building designed to save energy, satisfy occupants
• Shading systems and lighting control systems were rigorously
developed and evaluated in a full scale test bed
• Owners engaged key systems suppliers via performance specs
• 2013: Systems (dimming, shading, UFAD) worked well;
Compared to a similar Code-compliant building:
–56% lighting energy savings
–24% total energy savings
–21-25% reduction in summer peak demand
–Economic Paybacks appear very reasonable
–Overall Occupant Satisfaction is high
• Outcome: “All-glass” building w/ Integrated Building Systems
performs better than a prescriptive “code-compliant” building
