Modelling Economically optimal heat supply to low energy building areas – The...IEA-ETSAP
The document analyzes the economically optimal heat supply options for new low-energy building areas (LEBs) located near urban areas in Sweden. It models three options: individual heating systems for each building, a small local district heating system within the LEB area, or connecting to the larger district heating system of the nearby urban area. The analysis considers various LEB densities and distances to urban areas. It finds that connecting to a large urban heating network is generally the lowest cost option due to economies of scale in transmission and distribution costs. The cost components, including transmission and distribution costs, vary significantly based on density and distance.

The usage of thermoelectric generator as a renewable energy sourceTELKOMNIKA JOURNAL
Currently thermoelectric generators (TEG) are widely used in biomedical, military and space satellite power applications. TEG of high power plants are mostly used in automobile and industrial engines. This paper discusses TEG as a renewable energy source. Here the TEG in the application is used in the thermoelectric generator power plant. The working principle of this thermoelectric generator is on the heat side of the TEG peltier which is coated in metal in the form of aluminum, which is heated by a heater. And the cold side of the TEG Peltier is placed on the heat sink (as a heat dissipation metal). Heatsinks are submerged in water which are submerged about half or more. If the temperature of the metal being heated and the temperature of heat dissipation metal have a certain difference, then the temperature difference causes TEG to start working. The greater the temperature difference, the greater the electrical energy produced will be. However, if the temperature difference is too large it will damage the bismuth semiconductor material used. After TEG starts working it will produce voltage and current.

This document summarizes the results of modeling pathways for Germany's energy transition and achieving its climate targets. It finds that:
1) A fast phase out of coal in Germany by 2030-2035 can help meet short term climate targets but stronger European cooperation is needed to achieve long term 2050 targets.
2) National actions through a "Coalition of the Willing" among some EU states can help bridge gaps but will not be sufficient on their own.
3) A fast coal phase out would increase electricity costs slightly but require large additional system costs of €41-106 billion that would need to be compensated.
4) Replacing coal primarily relies on increased gas, imports,

Getting Solar PV off the ground - some practical feedback from the Worthy Far...Farming Futures
The document discusses considerations for installing a solar photovoltaic (PV) system on a farm, based on lessons learned from installing a system at Worthy Farm. Key factors discussed include site selection considering orientation, shading and electrical supply; performance forecasting requiring a third-party report; structural and safety reviews of the building; planning and grid capacity checks; ensuring proper plant room conditions for inverters; rodent proofing of wiring; safety during installation; security considerations; and selecting an experienced installer that can provide a comprehensive turnkey design and installation service.
Solar PV Systems (Engineering, wiring & grid connection) - Martin Cotterell (...Farming Futures
Sundog Energy is an installer of solar photovoltaic systems since 1995. They have installed hundreds of systems across the UK on various building types. Their current projects include a 240kWp system at Kings Cross Station and a 50kWp facade system for a Newham Council building. PV systems generally consist of solar panels that convert sunlight to electricity, an inverter to convert DC to AC, and a connection to the building's electrical distribution. Proper siting and components are important for performance. MCS certification provides standards for installers and products but does not guarantee all aspects of safety, experience or system complexity.
In October 2011, WRI launched a five-year global initiative to advance the progress of building environmentally sustainable and livable cities in China, India, and Brazil. We intend to develop low-carbon city models and pathways for environmentally sustainable urbanization, by partnering with four urban centers to increase energy efficiency, curb greenhouse gas emissions, and improve water quality, urban mobility and land use.
This document discusses densities and compactness in developing country cities. It finds that densities are much higher than in developed countries, facilitated by smaller dwelling sizes, mixed land uses, and higher densities near city centers. While central city densities are higher, overall city areas are larger in developing countries. Higher densities support more diverse transit options but congestion is also higher. Compactness provides some environmental and infrastructure benefits but does not necessarily correlate with better environmental quality. Lessons are that developing country transportation cannot be directly replicated and compactness results less from planning than from economic factors.

CCS as least-cost options for integrating intermittent renewables in low-carb...Global CCS Institute
Intermittent renewable energy sources (intermittent‐RES) such as wind and solar PV can be a key component of the resulting low‐ carbon power systems, but their intermittency requires more flexibility from the rest of the power system to maintain system stability. In this study, the efficacy of five complementary options to integrate intermittent RES at the lowest cost is evaluated with the PLEXOS hourly power system simulation tool for Western Europe in the year 2050. Outcomes of the study show that amongst the various options to reduce system’s costs one of the most effective is the implementation of CCS at natural gas‐fired power plants.
In this webinar, Machteld van den Broek, Assistant Professor at the Utrecht University, and Anne Sjoerd Brouwer, PhD student at the Utrecht University, presented the method and the results of the study.

The methodology uses optimization algorithms to determine the optimal PV panel technologies, sizing, orientation, and other parameters to meet energy demand at minimum cost. It involves forecasting building energy demand, simulating PV panel performance under different conditions, maintaining a database of PV technologies and costs, and using genetic algorithms to iteratively optimize the design. The methodology is intended to provide an easy to use tool for designers, installers and other professionals to cost-effectively design BIPV installations.
This document summarizes the status of building integrated photovoltaic (BIPV) applications in Malaysia. It discusses that between 1998-2002, Malaysia successfully completed several pilot BIPV projects totaling over 400kWp installed across various buildings. Key lessons learned included addressing issues like roof leakage and lightning protection that are prevalent in the tropical climate. While BIPV system costs in Malaysia have decreased significantly, costs remain relatively high compared to other countries due to components still being imported and lack of local market. The government is now working to further develop BIPV through new programs and a national steering committee on renewable technologies.

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.

• Solar analysis on DIVA for calculating the optimal
distance between the louvres: 75 cm
115. • Wind speed less than 5m/s Below 1.5m
• In summer the pressure difference of front and back side of the
building has to be about 2 Pa to ensure enough natural ventilation
• In winter the pressure difference of front and back side of the
building has to be less than 5 Pa (except for the first row of the
buildings towards wind)
