Book excerpt: Abstract: Green architecture, sustainable buildings, environmentally friendly, and other terms have recently become popular in the construction fields among both professionals and non-professionals. Although it is mostly needed and highly feasible, the application of these ideas is not yet at the same level of popularity in Egypt. Researchers are trying to fill this gap by providing different types of recommendations, methodologies, and guidelines to be followed. The aim of this research is to propose a method to be used in solving the energy problem in the building sector in Egypt. Since it is concerned with the existing building stock, the methodology will be addressing retrofitting strategies not new design strategies. The research suggests the nZEB (net zero-energy buildings) methodology as a possible solution for the problem and provides a guideline to be used among the rest of existing building types. The research utilizes energy simulation to validate its initial assumptions and to test the feasibility of the proposed guideline. The final outcome of the research is a method that combines both retrofitting and renewable energy strategies that suit the Egyptian context and potential to convert existing buildings to nZEB buildings. The study starts with the analysis of the current situation of both the existing buildings and the energy sector in Egypt. First, it reviews the classification of the existing building types in the Egyptian context, analyzing the energy consumption patterns and the inefficiencies leading to these patterns, then defining the nZEB concept to familiarize the reader with its different aspects. The empirical part of the study utilizes several cases for a number of prototypes of residential building types in Egypt. Finally, a suggested guideline is applied to an actual existing building and its feasibility is tested by simulation. The research concludes a potential energy saving by applying nZEB strategies to existing residential buildings in Egypt. Future research is required on different building types to validate the nZEB across different building types.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies show that 39% of World's total energy consumption is demanded by buildings. In order to supply this increasing energy demand, renewable energy sources shall be occupied within buildings. Solar energy is a highly available but not yet efficient enough energy source. Energy usage can be sustained by renewable energy sources. Therefore, Net-Zero Energy Building's (NZEB) shall be designed. A NZEB supplies the required amount of energy to a building with renewable energy sources. This thesis allows future researches and studies for retro-fitting existing buildings into NZEB. New buildings can always be adopted during the project phase but existing buildings are harder to convert. Building Information Modeling method is used to find the optimum renovation solution for an Existing building in Florida Tech Campus. Worldwide acknowledged software REVIT MEP is used as a tool for calculations. After finding the optimum design solution, solar panels are located on top of the roof of building to compensate total energy demand.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a methodology for the design, construction, monitoring, optimization, and post-occupancy evaluation of net-zero and positive-energy communities based on the experiences gained in the EU Horizon 2020 ZERO-PLUS project. It describes the steps, tools, and methods developed during the project, providing practical information for the energy and construction sector that will be of interest to students, engineers, architects, developers, and professionals working around high performance architecture and sustainable communities. Through the ZERO-PLUS project, a consortium of 32 partners from eight countries, including academic institutions, technology providers, architects, and construction companies, designed four communities covering completely different geo-climatic regions, construction practices, and cultural backgrounds in Cyprus, Italy, France, and the UK. The communities were designed, optimized, constructed, monitored, handed over to tenants, post-occupancy evaluated, and troubleshooted through a system of continuous collaboration and data acquisition. This book presents these case studies and shows how the project targets of reducing electricity consumption below 20 kWh/m2/y, increasing electricity production from Renewable Energy Systems to over 50 kWh/m2/y, and at cheaper costs when compared to current zero-energy buildings were reached and surpassed. These cases demonstrate that a holistic and interactive approach to design and construction can bring communities a high standard of sustainability. The key features of the book include: Practical guidance drawn from the interdisciplinary, international, and remote cooperation between experts from academia and industry across the construction sector A survey of the state-of-the-art on net-zero and positive-energy communities, including the experience and the lessons learned from previous projects and from the ZERO-PLUS project Descriptions of novel emerging renewable energy technologies, integrated into real case study communities to achieve the energy generation target of the communities A comprehensive set of approaches, tools, guidelines, best practices, challenges, and lessons learned from the five-year ZERO-PLUS project and the completion of four residential case studies to inform the reader of how to achieve affordable net-zero energy communities Four typologies of residential communities located in different climatic conditions are presented, touching on the critical aspects of the design, construction, monitoring, and occupancy phase A discussion of future trends for developing communities that are more liveable, accessible, and sustainable and which can comply with new energy policies in a way that is affordable for the owners and residents.

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 Development and Analysis of Approaches and Strategies to Facilitate the Conversion of Canadian Houses Into Net Zero Energy Buildings written by S. Rasoul Asaee and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional building design is not aligned with modern housing requirements. Growing energy demand, international pressure to reduce greenhouse gas (GHG) emissions and increasing cost of energy motivate the building energy research community to provide alternative solutions to improve traditional housing. One of the most popular options for housing is the adoption of net zero energy building (NZEB) concept, which is defined as a building that exports more or equal energy than it imports. So far, majority of research efforts have been focused on finding solutions for the design, construction and operation of new NZE houses. Since the renewal of the housing stock is slow, the impact of introducing NZEBs into the housing stock would not be significant for many years, making the conversion of existing houses into NZE or near NZE buildings an important objective to reduce energy consumption and associated GHG emissions. Canada has numerous climatic and geographical regions and the Canadian housing stock (CHS) is diversified in terms of vintage, geometry, construction materials, envelope, occupancy, energy sources and heating, ventilation and air conditioning system and equipment. Therefore, strategies to achieve NZE and near NZE status with the current stock of houses need to be devised considering the unique characteristics of the housing stock, the economic conditions and energy mix available in each region. Identifying and assessing pathways to converting existing houses to NZE or near NZE buildings at the housing stock level is a complex and multifaceted problem and requires extensive analysis on the impact of energy efficiency and renewable/alternative energy technology retrofits on the energy use and GHG emissions of households. To develop and analyze techno-economically feasible approaches and strategies to support the conversion of Canadian houses into NZE and near NZE buildings by implementing energy efficiency and renewable/alternative energy technology retrofits, the Canadian Hybrid Residential End-Use Energy and GHG Emissions Model (CHREM), a state of the art residential sector energy and GHG emission model statistically representative of the CHS, was expanded and used. For this purpose, a wide range of energy efficiency and renewable/alternative energy technology retrofits including envelope modifications, appliance/lighting upgrade, internal combustion engine and Stirling engine cogeneration, solar combisystem, air to water heat pump, solar assisted heat pump and building integrated photovoltaic and thermal system architectures were developed/adapted and models were incorporated into the CHREM. The impact of the retrofit measures on the energy consumption and GHG emissions of the CHS was investigated. Numerous retrofit scenarios involving various technologies were developed for each province and post-retrofit source energy intensity and GHG emission intensity of houses were determined to evaluate the performance of the retrofit scenarios to achieve NZE and near NZE status for Canadian houses. The results indicate that substantial energy savings and GHG emission reductions are techno-economically feasible for the CHS through careful selection of retrofit options. While achieving large scale conversion of existing houses to NZEB is not feasible, achieving near NZE status is a realistic goal for a large percentage of Canadian houses.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The building sector has a large environmental footprint that contributes to the current global GHG emissions. Implementing energy efficiency measures in the building sector will assist in reducing energy consumption and has the potential for substantial CO2 reductions. There is an increased interest for net-zero energy buildings to reduce the high energy demands associated with buildings. This project investigates the techno-economic feasibility of implementing a net-zero energy retrofit for a MURB in Halifax, Nova Scotia. A MURB was selected and modeled in its current state using the building performance software OpenStudio. Iterations of energy efficiency modifications were implemented until the total annual energy consumption was reduced to a level that would allow for the building to achieve net zero energy status. The building reached net zero energy operation after the addition of 2,280 solar panels, or 47,400 ft2 of solar cells. The economic feasibility was determined using the TCC method.

This book was released on 2017 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] In most developed economies, buildings are directly and indirectly accountable for at least 40% of the final energy use. Consequently, most world cities are increasingly surpassing sensitive environmental boundaries and continue to reach critical biophysical thresholds. Climate change is one of the biggest threats humanity faces today and there is an urgent need to reduce energy use and CO2 emissions globally to zero or to less than zero, to address climate change. This often leads to the assumption that buildings must reduce energy demand and emit radically less CO2 during construction and occupation periods. Certainly, this is often implemented through delivering 'zero energy buildings'. The deployment of residential buildings which meet the zero energy criteria thereby allowing neighbourhoods and cities to convert to semi-autonomous energy systems is seen to have a promising potential for reducing and even eliminating energy demand and the associated greenhouse gas emissions. However, most current zero energy building approaches focus solely on operational energy overlooking other energy uses such as embodied energy and user transport energy. Embodied energy constitutes all energy requirements for manufacturing building materials, construction and replacement. Transport energy comprises the amount of energy required to provide mobility services to building users. Zero energy building design decisions based on partial evaluation and quantification approaches might result in an increased energy demand at different or multiple scales of the built environment. Indeed, recent studies have demonstrated that embodied and transport energy demands account for more than half of the total annual energy demand of residential buildings built based on zero energy criteria. Current zero energy building frameworks, tools and policies therefore may overlook more than ~80% of the total net energy balance annually.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "According to the World Green Building Council (WGBC), the construction industry accounts for more than 35% of global energy use and nearly 40% of energy-based carbon emissions. To have a resilient built environment, the building sector requires integration of optimized energy efficiency and utilization of renewable energy in building design and operations. Net-Zero Energy Buildings (NZEBs) have the potential to be one of the climate solutions that can push the built environment towards decarbonization. Though there has been a significant growth in the number of NZEBs in the United States in the last decade, NZEBs still face challenges in their market penetration and there still are several concerns about adopting NZEBs. There is an urgent need to understand the kind of barriers that exist today since the perceptions of NZEBs have changed over the years. This thesis explores what NZEBs are and identifies the challenges and barriers that exist in implementing Net-Zero Energy projects with a focus on residential and commercial buildings in the United States. The study sought to understand the current scenario for NZEBs through interviews with professionals who have been involved with working on Net Zero Energy goals in the built environment in various roles which formed the primary data. The secondary data obtained through literature review was also used to realize the barriers and challenges of NZEB implementation. The comparison of both primary and secondary data helped understanding the changing landscape for NZEB implementation. The motivation behind choosing the above topic was a combination of my educational background, interests and the knowledge of sustainability and climate change gained through my Masters in Sustainability studies.

Download or read book Approaching Net Zero Energy in Existing Housing written by Canada Mortgage and Housing Corporation and published by . This book was released on 2007 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research project explored the technical feasibility of reducing the energy consumption of existing houses to net zero on an annual basis. The project characterized the energy consumption patterns in existing housing and compiled energy efficiency and energy generation measures. Through this work, the potential for energy reduction, energy storage and renewable energy generation was assessed. The project also considered the trade-offs in comfort, cost, and convenience necessary to attain very low energy consumption in existing housing. This is conceptual research as the possibility of creating a net-zero-energy house from an existing dwelling is extremely challenging. The research showed that some houses (e.g . bungalows) and some locations (e.g. Vancouver) had a far better chance of achieving net zero energy usage due to their inherent advantages. Most of the modelled houses were able to attain very low heating energy requirements. The compensating energy production, through solar thermal and photovoltaics, is often limited in effectiveness by roof size and orientation, as well as by high capital costs. The report provides a good background on what is possible for older houses and at what cost. It also provides interesting information on potential wall assemblies for these houses and decision trees on which energy retrofits to select for specific houses.

Book excerpt: This dissertation aims to utilize the application of Vehicle to Home technology to reach NZEB by developing two new models in two phases; the macro based excel model (NZEB-VBA) and agent based model (NZEB-ABM). Using these two models, homeowners can calculate the savings through implementing abovementioned technologies which can be considered as a motivation to move toward greener buildings. In the first step, an optimization analysis is performed first to select the best design alternatives for an energy-efficient building under the relevant economic and environmental constraints. Next, solar photovoltaic sources are used to supply the building's remaining energy demand and thereby minimize the building's grid reliance. Finally, Vehicle to Home technology is coupled with the renewable energy source as a substitute for power from the grid. The whole algorithm for this process will be running in the visual basic environment.

This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The buildings respecting the concept ,ÄúNet Zero energy,Äù are becoming more and more flowering in the world these last years. The main goal of this research is to evaluate the different possibilities of implementation of buildings with Net zero energy and low environmental impacts in Sub-Saharan Africa. The proposed building is 80% made of local materials with low carbon emissions and especially at lower cost. The optimization and modeling of the building is carried out by the Design Builder software, which is a world-renowned software in the field of optimization of comfort, cost, carbon reduction, etc. By fixing the insulation thickness up to 11¬†cm, cooling and heating energy are found equal to zero during the different operating seasons in this residential building. The results show that the optimal solution to consider a net zero energy building in Antananarivo city requires an additional expense estimated at 40% of the cost of buildings more conventional encountered in the island. This will save $475 each year starting in 2030, with 99% reduction in the CO2 release. The choice of local materials with low conductivity, low emissions, and low cost, has a significant impact on the implementation of a sustainable building, and more adapted to climate change concept.
