To date, most green construction has been geared to commercial structures or affordable housing. An overlooked niche is market-rate single-family homes. While buyers are beginning to ask for green homes or are remodeling existing homes with green features, this type of construction is often overlooked due to economic feasibility. We explore issues relating to making green housing affordable. Even if building a completely green house is not economically feasible, incorporating green elements (materials, site planning, energy rebates) into the project is almost always possible and can help the environment.

Australia’s commercial sector is feeling the fallout of the economic downturn. A sharp reduction in demand for office space, along with increasing unemployment and declining economic growth forecasts are beginning to take a toll on the sector.
However, the time ahead could also pose some significant opportunities.
In this report we investigate how building owners can use this ‘down time’ to reposition their assets, increase energy efficiency and improve value. By rethinking the way building owners invest, there are opportunities to achieve greenhouse gas (GHG) reductions while creating a raft of employment opportunities across the nation. This effectively leads to a stimulus ready productivity and performance improvement of a significant part of our built environment.

Finding Value in Distributed Generation, Before it Finds YouJohn Farrell
ILSR Senior Researcher John Farrell is giving this presentation to a collaborative meeting of the Federal Energy Regulatory Commission (FERC) and the National Association of Regulatory Commissioners (NARUC) this weekend. It highlights the proven value of distributed solar to utility grid systems and the urgent need for regulators and utilities to incorporate this value into their long-term plans, because distributed and unsubsidized solar is poised to explode as it reaches retail price parity.

Which Costs Less? A Surprising Comparison of Utility-Scale, Community, and Ro...John Farrell
Electric utilities often misrepresent the cost of solar energy to serve their own profit interests. The truth? Costs are comparable for utility-scale, rooftop, and community solar––and local solar offers benefits aside from clean electricity, from reducing energy burdens for electric customers to providing resilience in the face of natural disaster. State legislatures should create policies to capture the benefits of all sizes and ownership methods of building more solar energy, but should especially work to undo years of utility misdirection by promoting local solar.

Reverse Power Flow: How solar+batteries shift electric grid decision making f...John Farrell
For 100 years, most decisions about the U.S. electric grid have been made at the top by electric utilities, public regulators, and grid operators. That era has ended.
Small-scale solar has provided one-fifth of new power plant capacity in each of the last four quarters, and over 10 percent in the past five years. One in 5 new California customers of the nation’s largest residential solar company are adding energy storage to their solar arrays. Economic defection––when electricity customers produce most of their own electricity––is not only possible, but rapidly becoming cost-effective. As the flow of power on the grid has shifted one-way to two-way, so has the power to shape the electric grid’s future.
In 4 weeks, citizens of Decorah, Iowa, will vote whether to take over the electric company for more local control. In this talk from March 26, John Farrell explains the advantages and opportunities of local power.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
