“AUTONOMOUS DOMICILE” stands for self-reliant structure or net zero energy building. An autonomous domicile can be defined as a building in which renewable energy is created on the structure itself and same is used for the meeting energy requirements of the structure. This project is mainly constant rated on promotion and optimum use of five components such as Solar Energy, Wind Energy, Rainwater Harvesting, Biogas and Green Building on the structures or buildings to meet their energy requirements and at the same time to reduce the use of non-renewable energy. The installation and orientation of these five components in the structure in such an integrated way so that maximum output can be obtained from the each component have been studied in this project. We have studied in detail about each and every component us as their installation method, the process of energy production, how much input is needed to produce the optimum amount of output from the components and also about their charges of installation.
Energy Conservation is become a necessity for the future of mankind. Energy resources are depleting on a large scale so renewable resources of energy like solar energy and wind energy are used to convert into the necessary forms of energy.

This document discusses renewable energy and green technology. It defines energy and lists different forms of energy, including electrical, mechanical, chemical, heat, and nuclear. Energy resources are classified as either primary/non-renewable sources like coal, oil, and natural gas, or renewable sources like solar, wind, biomass, and geothermal that recur naturally. Renewable sources are attractive because they are inexhaustible, have low operating costs, are site-specific so transmission is not needed, and cause less pollution than fossil fuels. However, renewables also have disadvantages like low energy density requiring larger plants, intermittency due to varying natural conditions, lower efficiencies, and higher upfront costs.

An integrated approach applying multiple strategies is needed to maximize energy savings.
A zero energy building is a building that produces as much energy as it consumes annually through renewable energy sources like solar panels and wind turbines. It has highly efficient design and construction features to minimize energy usage. A zero energy building generates enough renewable energy to meet its own annual energy consumption through solar, wind, or other renewable sources. It can be connected to the electric grid but has no net energy consumption on an annual basis. Zero energy buildings reduce greenhouse gas emissions and fossil fuel dependence compared to conventional buildings.
The document provides information on energy conservation and different types of energy. It discusses that energy can be converted from one form to another but cannot be created or destroyed. Renewable energy sources like solar, wind and hydro are responsible for a small percentage of carbon dioxide emissions while non-renewable sources like coal are the main cause of global warming. The document also highlights the importance of conserving energy to reduce dependence on imports and make efficient use of limited resources. Various strategies for conserving energy in lighting, air conditioners, motors and through renewable options are presented.
Energy conservation is important to reduce costs, promote economic security, and protect the environment for future generations as fossil fuels are non-renewable. While industrialized countries rely heavily on fossil fuels, transitioning to renewable sources like solar, wind, hydroelectric, geothermal, and biomass is key. Individuals can conserve energy through everyday actions like using appliances efficiently, insulating homes, and choosing active transportation when possible. As fossil fuel reserves are depleted, a combined effort of alternative energy development and behavioral changes around energy use is needed.
Net zero energy buildings are highly energy efficient buildings that produce as much renewable energy as they consume over the course of a year. They have net zero site energy, net zero source energy, net zero energy costs, and zero emissions. Buildings account for up to 40% of global energy consumption, so incorporating energy efficient design strategies can significantly reduce usage. With renewable energy sources, buildings can meet all of their energy needs. The document provides examples of design methods and materials that can be used to achieve net zero energy buildings and reduce costs, emissions, and increase comfort. It also highlights India's first net zero energy building as a case study.

Zero energy buildings economical and environmental aspectsMD ASIF AKBARI
The document discusses zero energy buildings and renewable energy sources. It defines a zero energy building as one that generates as much energy through renewable sources as it consumes from the grid. It notes that solar and wind energy will be the major contributors for zero energy buildings due to their widespread availability. While biogas can also be used, it requires large quantities of waste and is not feasible everywhere. Geothermal energy has great potential but more research is still needed to fully tap into its capacity. The document concludes that solar and wind will be the primary renewable sources for powering zero energy buildings.
This document provides an introduction to net zero energy buildings (ZEBs). It defines ZEBs as buildings that produce as much energy as they consume on an annual basis. There is no single agreed upon definition, as definitions vary based on priorities and metrics used. The document outlines some key concepts and factors that make a building a ZEB, such as site selection, passive solar design, building envelope, and active energy systems. It also provides a brief history of ZEBs and discusses their benefits. Examples of ZEB projects from Europe and the United States are summarized.
[Metropolia Student Project Seminar 24.5.] Zero Energy Buildings, Group BGBC Finland
This document discusses zero energy buildings and provides examples from Canada, New Zealand, and the United States. It defines zero energy buildings and compares different standards. The Riverdale NetZero project in Canada and Little Greenie in New Zealand are presented as residential examples that use solar panels, thermal mass, and heat recovery systems. A large zero carbon emission office building in St. Louis, Missouri uses photovoltaics, solar thermal tubes, and is 76% carbon reducing. The document suggests Finland could adopt zero energy building practices using local climate and technologies from neighbors.
This document discusses net zero energy buildings (NZEBs). It provides context on climate change and government policies driving the adoption of NZEBs. It defines NZEBs as buildings that produce as much renewable energy as they consume on an annual basis. However, there is no consistent definition as the energy balance can be measured at the site or source level and can include energy use, emissions or costs. The document also discusses practical challenges to achieving true net zero status and examples of organizations pursuing net zero energy goals.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to look at how improvements are occurring in zero energy buildings. Improvements in the energy efficiency of appliances, in aerogels for insulation, in solar cells for electricity generation, and in passive solar design are helping us reduce energy usage. The goal is zero energy usage of external electricity and fossil fuels.
The document summarizes a Zero Energy Building (ZEB) in Singapore that was retrofitted from an existing building. The ZEB produces enough renewable energy, through solar panels and other green technologies, to power its own operations and reduce its energy costs to zero. It serves as a test bed for green building technologies and aims to educate practitioners and students on energy efficiency and sustainability. Some features of the ZEB mentioned include natural ventilation, daylighting systems, electrochromic glass, solar panels, and vertical greenery walls.
A zero-energy building, also known as a zero net energy (ZNE) building, net-zero energy building (NZEB), or net zero building, is a building with zero net energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on the site,or in other definitions by renewable energy sources elsewhere.These buildings consequently contribute less overall greenhouse gas to the atmosphere than similar non-ZNE buildings. They do at times consume non-renewable energy and produce greenhouse gases, but at other times reduce energy consumption and greenhouse gas production elsewhere by the same amount.
A joint presentation between myself and John Andary from Stantec. Covers the the process and strategies used to get this 218,000 SF office building on the NREL campus to net zero energy.
