Download or read book Net Zero Energy Buildings written by Linda Reeder and published by Routledge. This book was released on 2016-03-31 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents 18 in-depth case studies of net zero energy buildings—low-energy building that generate as much energy as they consume over the course of a year—for a range of project types, sizes, and U.S. climate zones. Each case study describes the owner’s goals, the design and construction process, design strategies, measurement and verification activities and results, and project costs. With a year or more of post-occupancy performance data and other project information, as well as lessons learned by project owners and developers, architects, engineers, energy modelers, constructors, and operators, each case study answers the questions: What were the challenges to achieving net zero energy performance, and how were these challenges overcome? How would stakeholders address these issues on future projects? Are the occupants satisfied with the building? Do they find it comfortable? Is it easy to operate? How can other projects benefit from the lessons learned on each project? What would the owners, designers, and constructors do differently knowing what they know now? A final chapter aggregates processes to engage in and pitfalls to avoid when approaching the challenges peculiar to designing, constructing, and owning a net zero energy building. By providing a wealth of comparable information, this book which will flatten the learning curve for designing, constructing, and owning this emerging building type and improve the effectiveness of architectural design and construction.

Download or read book Cost Optimal and Nearly Zero-Energy Buildings (nZEB) written by Jarek Kurnitski and published by Springer Science & Business Media. This book was released on 2013-11-20 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cost optimal and nearly zero energy performance levels are principles initiated by the European Union’s (EU) Energy Performance of Buildings Directive which was recast in 2010. These will be major drivers in the construction sector in the next few years, because all new buildings in the EU from 2021 onwards are expected to be nearly zero energy buildings (nZEB). This book introduces the technical definitions, system boundaries, energy calculation methodology and input data needed to set primary energy based minimum/cost optimal and nZEB requirements in national energy frames. Worked examples are provided to illustrate the calculation of delivered, exported and primary energy, and renewable energy contribution. Five case studies of high performance nZEB office buildings across Europe are reported to show alternative technical solutions and to draw some general design rules based on completed nZEB buildings. Specific features of the nZEB design process, especially in the early stages, and architectural competitions are included. These describe important design issues in the scoping and conceptual design phase, allowing design streams to be controlled so that specified targets can be met. This book is intended for readers who need to be aware of or are working with the energy performance of buildings – for decision makers in public and private sectors, architects, engineers, construction clients, consultants, contractors, manufacturers and students. The editor of this book, Professor Jarek Kurnitski has made major contributions to the preparation of the European REHVA nZEB technical definition and has developed energy calculation frames for current Estonian and Finnish energy performance regulations. He is the leader of nZEB research at Tallinn University of Technology in Estonia and Aalto University in Finland, and he has over 300 publications.

Download or read book Modeling, Design, and Optimization of Net-Zero Energy Buildings written by Andreas Athienitis and published by John Wiley & Sons. This book was released on 2015-01-26 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building energy design is currently going through a period of major changes. One key factor of this is the adoption of net-zero energy as a long term goal for new buildings in most developed countries. To achieve this goal a lot of research is needed to accumulate knowledge and to utilize it in practical applications. In this book, accomplished international experts present advanced modeling techniques as well as in-depth case studies in order to aid designers in optimally using simulation tools for net-zero energy building design. The strategies and technologies discussed in this book are, however, also applicable for the design of energy-plus buildings. This book was facilitated by International Energy Agency's Solar Heating and Cooling (SHC) Programs and the Energy in Buildings and Communities (EBC) Programs through the joint SHC Task 40/EBC Annex 52: Towards Net Zero Energy Solar Buildings R&D collaboration. After presenting the fundamental concepts, design strategies, and technologies required to achieve net-zero energy in buildings, the book discusses different design processes and tools to support the design of net-zero energy buildings (NZEBs). A substantial chapter reports on four diverse NZEBs that have been operating for at least two years. These case studies are extremely high quality because they all have high resolution measured data and the authors were intimately involved in all of them from conception to operating. By comparing the projections made using the respective design tools with the actual performance data, successful (and unsuccessful) design techniques and processes, design and simulation tools, and technologies are identified. Written by both academics and practitioners (building designers) and by North Americans as well as Europeans, this book provides a very broad perspective. It includes a detailed description of design processes and a list of appropriate tools for each design phase, plus methods for parametric analysis and mathematical optimization. It is a guideline for building designers that draws from both the profound theoretical background and the vast practical experience of the authors.

Download or read book Net zero energy buildings written by Karsten Voss and published by Walter de Gruyter. This book was released on 2012-12-10 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Net zero energy buildings, equilibrium buildings or carbon neutral cities – depending on location and the reasons for making the calculation, the numbers are run differently. The variety of terms in use indicates that a scientific method is still lacking – which is a problem not just in regard to international communication, but also with respect to planning processes as a response to energy challenges. The clarification and meaning of the most important terms in use is extremely important for their implementation. Since October 2008, a panel of experts from an international energy agency has concerned itself with these topics as part of a project entitled “Towards Net Zero Energy Solar Buildings”. The objective is to analyse exemplary buildings that are near a zero-energy balance in order to develop methods and tools for the planning, design and operation of such buildings. The results are documented in this publication: In addition to the presentation of selected projects, it is not just architectural showcase projects that are shown – the focus is on relaying knowledge and experience gained by planners and builders. Even if many questions remain unanswered: Project examples that have already been implemented prove on a practical basis that the objective of a zero energy balance is already possible today."

Download or read book The New Net Zero written by Bill Maclay and published by Chelsea Green Publishing. This book was released on 2014 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new threshold for green building is not just low energy, it's net-zero energy. In The New Net Zero, sustainable architect Bill Maclay charts the path for designers and builders interested in exploring green design's new-frontier net-zero-energy structures that produce as much energy as they consume and are carbon neutral. In a nation where traditional buildings use roughly 40 percent of the total fossil energy, the interest in net-zero building is growing enormously--among both designers interested in addressing climate change and consumers interested in energy efficiency and long-term savings. Maclay, an award-winning net-zero designer whose buildings have achieved high-performance goals at affordable costs, makes the case for a net-zero future; explains net-zero building metrics, integrated design practices, and renewable energy options; and shares his lessons learned on net-zero teambuilding. Designers and builders will find a wealth of state-of-the-art information on such considerations as air, water, and vapor barriers; embodied energy; residential and commercial net-zero standards; monitoring and commissioning; insulation options; costs; and more. The comprehensive overview is accompanied by several case studies, which include institutional buildings, commercial projects, and residences. Both new-building and renovation projects are covered in detail. The New Net Zero is geared toward professionals exploring net-zero design, but also suitable for nonprofessionals seeking ideas and strategies on net-zero options that are beautiful and renewably powered.

Download or read book Advanced Techniques for the Design of Zero Energy Buildings written by Sassan Mohasseb and published by Nova Science Publishers. This book was released on 2021 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The overall aim of the first chapter is to improve the knowledge about the simulation of thermal indoor climate for buildings in different climate conditions and its application for computer-based simulations. The work is done in order to simplify the use of CFD as a powerful tool in order to model the temperature distribution within the building envelope in two real cases in Switzerland, and promote a comfortable indoor environment with a maximum reduction of energy consumption. High energy materials like cement, glass, brick and steel are typically used in building construction. However, it is possible to reduce the environmental impact of any structure through the use of alternative, low-energy materials such as Silica aerogels (aerogel-based plasters), Expanded Polystyrene (EPS), Polyurethane foams (PU), and Mineral wool (Stone or Glass). Increased interest has focused on the development of advanced sustainable construction materials (Nano thermal insulation materials, aerogels, etc.) with adequate mechanical properties and durability performance. The most convenient way to get the most out of their investment in a building is to use energy modeling software. The second chapter will be primarily concerned with the choice of materials, then the suitability of insulation exterior facades. Geothermal is the most energy efficient and environmentally friendly method of heating and cooling buildings. The design of borehole thermal energy, as a common type of geothermal energy, is presented in Chapter Three. The calculation is based on heat transfer principles, including a case study of a BHE for a one-story house with all the properties related to analyze the BHE, e.g., to calculate the changes in the temperature of the circulating fluid. Economic analysis of implementing renewable energy technologies in buildings is especially important for a transition away from the greenhouse emitting energies since a great majority of the current capital stock and infrastructure of today's economic systems are adjusted based on fossil-fuel energies. Chapter Four presents a diverse collection of examples with economic analysis of costs and paybacks covering warm vs cold, social complexes vs private houses, and new vs historical buildings. Solar energy has various uses besides more energy production and it can be incorporated in applications with cooling, heating and desalination processes. The main objectives of Chapter Five are to assess the degree of energy reduction using solar energy in buildings and to establish the requirements for energy-efficient design of buildings in cold/hot regions. Payback period analysis that evaluates the cost savings resulting from energy efficiency improvements is also addressed"--
