Versatile wooden windows In her book, the trained carpenter and architect Judith Resch looks at what scope still exists in modern window design and construction. The process of simplification is more difficult to achieve for windows than for most building components, since windows, due to their function, must meet high technical specifications. She presents a variety of window design projects that have one thing in common: they pursue a singular design concept using the simplest possible means. All projects are presented in detail with technical drawings and photographs. 10 simple wooden window designs From retrofitting historical windows to the possibilities of DIY design Precisely designed, handcrafted, highly repairable windows

Deine neue Solaranlage ist Vertrauenssache.Willkommen in unserem Universalratgeber Photo- voltaik, einem umfassenden Buch rund um das Thema Solarenergie ¿ von der Theorie bis zur Praxis. In eine Solaranlage zu investieren, ist wohl die beste Entscheidung die du als Hausbesitzer im Moment treffen kannst. Lass mich kurz erklären, weshalb ich dieser Überzeugung bin. Zum Einen sind die Energiepreise unbe- rechenbar geworden. Etwas unabhängiger von Strom- oder Gasversorgern zu werden und gleichzeitig auch noch Kosten zu sparen, ist ein wich- tiger Aspekt. Andere wollen so autark wie möglich sein, um sich zum Beispiel bei einem Stromausfall selbst versorgen zu können. Darüber hinaus ist auch der Umweltgedanke wichtig: CO2-Emissionen einsparen durch selbst auf dem Dach produzierten, grünen Sonnenstrom. Und damit nicht nur dir selbst, sondern auch dem Klima etwas Gutes tun. Eine Solaranlage ist heute so preisgünstig und so einfach zu erwerben wie noch nie zuvor. Dieses Buch soll aufzeigen, worauf du achten solltest, wenn du mit einem Anbieter sprichst, damit du viele Jahre Freude an deiner neuen Anlage hast, unabhängiger bist und natürlich auch jede Menge CO2 einsparst. Für Dich, für deine Kinder und für deren Kinder.

This book focuses on latent heat storage, which is one of the most efficient ways of storing thermal energy. Unlike the sensible heat storage method, the latent heat storage method provides much higher storage density with a smaller difference between storing and releasing temperatures.Thermal Energy Storage with Phase Change Materials is structured into four chapters that cover many aspects of thermal energy storage and their practical applications. Chapter 1 reviews selection, performance, and applications of phase change materials. Chapter 2 investigates mathematical analyses of phase change processes. Chapters 3 and 4 present passive and active applications for energy saving, peak load shifting, and price-based control heating using phase change materials.These chapters explore the hot topic of energy saving in an overarching way, and so they are relevant to all courses. This book is an ideal research reference for students at the postgraduate level. It also serves as a useful reference for electrical, mechanical, and chemical engineers and students throughout their work.FEATURESExplains the technical principles of thermal energy storage, including materials and applications in different classificationsProvides fundamental calculations of heat transfer with phase changeDiscusses the benefits and limitations of different types of phase change materials (PCM) in both micro- and macroencapsulationsReviews the mechanisms and applications of available thermal energy storage systemsIntroduces innovative solutions in hot and cold storage applications

In Zeiten des Klimawandels rücken neben dem Einsatz ressourcenschonender Materialien auch die Auswirkungen der klimatischen Bedingungen auf die Zusammensetzung von Baustoffen, Bauelementen und innerhalb der Baukonstruktion in den Vordergrund. Der Wärmeschutz als Bestandteil der bauphysikalischen Lehre spielt hierbei eine besondere Rolle. Ziele, wie die Reduzierung des Wärmeeintrags in Gebäude und eine Verhinderung der Auskühlung von Innenräumen bei geringen Außentemperaturen durch konstruktive Maßnahmen und die Wahl richtiger Materialien reduzieren den Einsatz zusätzlicher Energien für die Klimatisierung. In diesem Band werden die weiteren Ziele des Wärmeschutzes ausgearbeitet, durch bauphysikalische Grundlagen hinterlegt und die Umsetzung im Rahmen der Baustofflehre und Baukonstruktion dargestellt.

A celebrated international bestseller that exposes the ticking time-bomb underneath our new technological order.The resources race is on. Powering our digital lives and green technologies are some of the Earth's most precious metals - but they are running out. And what will happen when they do? The green-tech revolution will reduce our reliance on nuclear power, coal, and oil, but by breaking free of fossil fuels, we are setting ourselves up for a new dependence - on rare metals like cobalt, gold, and palladium. These are essential to electric vehicles, wind turbines, and solar panels, as well as our smartphones, computers, tablets, and other technologies. But we know very little about how rare metals are mined and traded, or their environmental, economic, and geopolitical costs - until now.

Master's Thesis from the year 2018 in the subject Engineering - Power Engineering, grade: 4.0, Kathmandu University, course: Master of Engineering in Electrical Power Engineering, language: English, abstract: This thesis presents the techno-economic feasibility study and reliability analysis of a hybrid energy system for Kathmandu University (KU), Dhulikhel, Nepal by using the resources available at premises. For the analysis, both on-grid and off-grid cases are considered. Various energy mix models are identified and optimized for the comparison purposes using HOMER (Hybrid Optimization Model for Multiple Energy Resources) software.The results are also analyzed and compared based on their reliability using Monte Carlo Simulation in RAPTOR software. Based on various combinations and simulations, best cost-effective and reliable model has been proposed. From this study, it is found that being a cost-effective model doesn¿t mean it¿s reliable too. In order to get the reliable supply, one may have to bear the extra cost to provide standby or emergency supply system. So, the cost plays an important role to determine what level of reliability is required.

Master's Thesis from the year 2019 in the subject Engineering - Power Engineering, , language: English, abstract: World population has reached 7 billion people in 2013 and there has been an increase in energy consumption, especially in emerging countries. In 2050 it will be more than 9 billion people living on the planet. Because of this, there has been a rapid increase in CO2 concentration levels, so the average planet temperature is rising, causing a greenhouse effect, as the CO2 is trapping in the heat and not releasing it. Consequently, ocean levels are rising, because of the shrinking polar ice caps. We also have seen an increase in the frequency of extreme atmosphere events around the globe. The refrigeration industry has contributed a lot to the global ozone depletion and global warming. To reduce the environmental impact by the heating, ventilation, air conditioning and refrigeration industry ¿ both commercial and domestic ¿ there is an urgent need to look for solutions that are both ozone friendly and CO2 friendly (greenhouse effect friendly).Eradicating the damage to the environment has encouraged the industrial and commercial refrigeration industry to investigate refrigerant alternatives that reduce the environmental impact although a good transition to them will also depend on the training that technicians acquire, as well as the understanding of the current and future benefits for the companies and the end users.This thesis aims at such a system which is both above mentioned. Once such a system is designed, it is of the utmost importance to test it and compare it with the systems that are being used currently to assess the benefits of using such system. The thesis has a focus on the liquid cooling systems such as water coolers and small commercial systems that help attain cooling of the liquids to a set temperature. In this thesis, the improvement of energy consumption and environmental degradation prevention is attained by switching the refrigerant used from R134a (current) to R290 (Propane) which is a natural refrigerant and Hydro Carbon Blend which is a mixture of refrigerants but is safer and environmentally friendlier. A comparison of both systems is done against the current system in terms of efficiency, energy consumption and chemical properties with respect to global warming potential and ozone depletion potential and ultimately proven that natural refrigerants and HC Blends are the refrigerants of the future.

Master's Thesis from the year 2017 in the subject Engineering - Power Engineering, grade: 2.0, RWTH Aachen University (Institute for Automation of Complex Power Systems), language: English, abstract: To rise to the challenge of the growing number of distributed Renewable Energy Sources (RES) for grid integration, Ancillary Service (AS) is increasingly crucial to maintaining the stability of power grid worldwide. In recent years, discussions about Data Centers (DCs) no longer limit to their energy efficiency. Considering the rising rigid demand from ICT customer and the high energy demand of DC, it is possible for DC to be one of Demand Response (DR) resources providing ASs in the smart grid.This thesis presents an online energy-aware scheduling algorithm based on Model Predictive Control (MPC), which realizes a proper adjustment of DC power demand, enabling the flexible operation of DC. The present work focuses on the identificationand implementation of an MPC strategy which aims at a proper scheduling for DC which makes the total power consumption of DC flexible to track the reference signal in a DR context. It is demonstrated how the combination and interaction of the components under DC architecture can be utilized to achieve the realizable potential of operational flexibility for AS. Numerical simulation results have been carried out aimed at the later application in real pilot DCs. Furthermore, the capacity of resisting disturbance of this MPC approach has been discussed.

Low-Temperature District Heating Implementation Guidebook. This guidebook was written between 2018 and 2021 by seventeen authors within the IEA DHC/CHP TS2 annex. The input came from 250+ literature references and 165 inspiration initiatives to obtain lower temperatures in buildings and heat distribution networks. The author group wrote 40 internal documents about early implementations of low-temperature district heating. Fifteen of these early implementations are presented in this guidebook. The guidebook contains aggregated information about the main economic drivers for low-temperature district heating, how to obtain lower temperatures in heating systems inside existing and new buildings, and how to obtain lower temperatures in existing and new heat distribution networks. An applied study of a campus system in Darmstadt shows the possibility of reducing temperatures in an existing heat distribution network with rather high temperatures. The competitiveness of low-temperature district heating is explored by analysing business models and heat distribution costs. Early adopters of low-temperature district heating are presented by examples and by identified transition strategies. Five groups of network configurations with fourteen variants are presented to be used for low-temperature district heating. Finally, all 165 identified inspiration initiatives and all 137 locations mentioned are listed.
