Dieses Buch stellt das Konzept der „Ganzheitlichen Sanierung“ vor, auf der Suche nach dem kürzesten Weg hin zum emissionsfreien Gebäudebestand. Dabei wird vom Zielzustand 2050 aus gedacht und geplant. Durch diese langfristige Perspektive wird ein effektiveres Vorgehen ermöglicht, denn man vermeidet dadurch, sich mit halbherzigen Sanierungsschritten die Zukunft zu verbauen. Wie solche annähernd emissionsfreien Gebäude bereits heute realisiert werden, beschreibt die abgeschlossene Sanierung eines Sparkassengebäudes mit einer abgestimmten Kombination aus Energieeffizienz, Erneuerbaren Energien und Einbeziehung der Mitarbeiter. Die vielschichtigen Maßnahmen werden Schritt für Schritt diskutiert, um die in der Praxis gemachten Erfahrungen für alle, die sich mit Sanierungen beschäftigen werden, weiter zu geben. Die Mitarbeiter der Sparkasse sind über den Zugewinn an Komfort und Umweltfreundlichkeit begeistert und der Sanierungsfahrplan weist einen Weg zum emissionsfreien Gebäude der Zukunft. Der Inhalt Die Stadt der Zukunft - Das Konzept der Ganzheitlichen Sanierung - Praxisbeispiel einer Ganzheitlichen Sanierung - CO2-freier Sanierungsfahrplan der Sparkasse - Beispiel Faktor 11 Sanierung Münsterländer Hof - Beispiel Effizienzhaus Plus im Altbau, Ulm - Beispiel Niederländischer Energiesprong Die Zielgruppen Bauherren, Immobilienbesitzer, Architekten, Ingenieure, Fachplaner, Energieberater Studierende der Fachrichtungen Architektur, Bauingenieurwesen und Clima Design Jeder, der sich mit der Sanierung von Gebäuden beschäftigt Der Autor Dipl.-Ing. Stefan Oehler ist Architekt & Ingenieur für Nachhaltiges Bauen mit der Spezialisierung auf Energieeffizientes Sanieren, seit 2011 Leiter der Abteilung GreenTech im Büro Werner Sobek Frankfurt.

Procedures for selecting external insulation that is likely to be subjected to an outdoor environment that includes combinations of contamination, ice, snow, or cold fog are specified by this guide. The selection methods are applicable to insulators, surge arresters, bushings, live line tools and other high voltage ac and dc apparatus with a rated voltage above 1 kV.

The objective of this document is to provide guidance for the development and implementation of a national energy efficiency (EE) investment program for public buildings in the Kyrgyz Republic. It begins by assessing the country's EE potential; analyzing its institutional, legislative and financial frameworks; reviewing the market for EE supply and services; and summarizing current barriers to EE implementation in the public sector. It then provides two forward-looking chapters: a vision 2040 list of medium- and long-term targets for a sustainable, climate-resilient, safe, and low-carbon stock of public buildings in the Kyrgyz Republic by 2040, with reference to the United Nation (UN) sustainable development goals and the draft concept for the development of the fuel and energy sector of the Kyrgyz Republic until 2040; and a roadmap and accompanying catalogue of recommended measures that sets out the steps and timeframe necessary to: improve the political and regulatory framework for EE; strengthen the delivery capacities of relevant institutions and sectoral stakeholders; and scale up the nation's EE investments in the country.

Cement is paramount for economic development and poverty reduction in emerging markets. Along with aggregates and water, cement is the key ingredient in the production of concrete, and, as such, is an essential construction material that enables large infrastructure projects in energy, water, and transport, as well as, importantly, the construction of modern buildings and urban infrastructure. Given the rapid urbanization rates in developing countries, cement is crucial for delivering on the climate-smart cities agenda. Emerging markets have been rapidly increasing their cement use and now account for over ninety percent of cement consumption worldwide. This report and an accompanying report on alternative fuels provide a summary of international best practice experience in the cement sector and focus on specific technical measures that could be implemented by cement plants to reduce their operating costs and improve their carbon footprints. The reports provide a plethora of practical information from implemented projects and include detailed technical descriptions, capital and operating costs, and case studies and references from locations where the measures have been implemented. A combination of general and in-depth information will make these reports a helpful read to both management and technical and operating personnel of cement plants as well as to a larger range of stakeholders.

Floating solar photovoltaic (FPV) technology is considered commercially viable, given the number of largescale projects that have been implemented. Challenges to its deployment remain, however, including the lack of a robust track record; uncertainty about costs; uncertainty about the environmental impact; and the technical complexity of designing, building, and operating on and in water (especially electrical safety, anchoring and mooring issues, and operation and maintenance). This handbook provides developers, utilities, contractors, investors, regulators, and decision makers with practical guidelines on FPV projects. Most of the handbook focuses on technical aspects relating to developing and operating FPV projects; some sections focus on commercial and legal aspects. Most of the observations are made for inland water bodies or near-shore coastal FPV installations. Many observations incorporate learning and opinions from the industry, but they are also based on the experience from the 1 megawatt-peak (MWp) floating solar testbed in the Tengeh Reservoir in Singapore. The testbed has a comprehensive monitoring system that tracks more than 500 parameters in real time, ranging from electrical to meteorological and module-related factors. Given the early stage development of the technology, this handbook cannot answer all questions about FPV. Further studies and field data analysis are needed to better understand some of the risks of FPV systems, especially their environmental impact and long-term performance. All recommendations provided in this report are based on past and current experiences, which are limited to several years of operating data for most projects. A longer operating lifetime of FPV installations will lead to new and improved recommendations and best practices; new developments in technology,testing, certification, and equipment/materials deployed are likely to evolve as the industry grows and diversifies. An active dialogue among all stakeholders, public and private, is required to further the global understanding of FPV technologies and the development of well-designed projects while minimizing possible negative environmental and social impacts. Through this handbook, the World Bank Group, the Energy Sector Management Assistance Program (ESMAP), and the Solar Energy Research Institute of Singapore (SERIS) hope to contribute to this goal and to disseminate lessons learned from early projects.
