Zero-Energy Design: an approach to make your building sustainable

Abstract: The concept of Zero Energy Building ZEB has gained wide international attention during last few years and is now seen as the future target for the design of buildings..

Researchers are continuously trying to find out the way of reducing the emission of carbon dioxide and implementations of the renewable energies technologies. The zero energy building concept is a realistic solution for the CO2 emission and reduction of energy demand in the building sector.

Zero energy building design has become a high priority for architects and multi-disciplinary researchers related to architectural engineering and building physics.

A zero energy building refers to a building with a net energy consumption of zero over a typical year. It implies that the energy demand for heat and electrical power is reduced, and this reduced demand is met on an annual basis from renewable energy supply. The renewable energy supply can either be integrated into the building design or it can be specifically provided for the building.

Buildings have a significant impact on energy use and the environment. The energy used by the building sector continues to increase, primarily because new buildings are constructed faster than old ones are retired.

So the role of various renewable energy sources in buildings has been getting full attention around the world. The scientific evidences for climate changes and the associated impacts of greenhouse gas emissions are becoming increasingly obvious. Scientists and built environment professionals are trying to find advanced. The renewable energy supply can either be integrated into the building design or it can be specifically provided for the building, for example as part of a community renewable energy supply system.

It also normally implies that the grid is used to supply electrical power when there is no renewable power available, and the building will export power back to the grid when it has excess power generation.

This two way flow should result in a net positive or zero export of power from the building to the grid. The zero energy building design concept is a progression from passive sustainable design. The object of a zero energy building is not only to minimize the energy consumption of the building with passive design methods, but also to design a building that balances energy requirements with active techniques and renewable technologies for example, solar photovoltaics, solar thermal or wind turbines.

It can be measured in terms of primary energy consumption or carbon emissions. Biaou et al. Photovoltaic PV panels. The results shows that it is possible to achieve a zero net energy for a R- type home with PV and geothermal heat pump. Clarke et al. The integrated software environment can help to identify suitable technology types and capacities at an early design stage. Norton and Christensen [4] presented the full year of energy performance data on the 3-bedroom Denver zero energy home combining envelope efficiency, efficient equipment, appliances and lighting, a photovoltaic system, passive and active solar thermal features.

This case study demonstrates that it is possible to build efficient affordable zero energy homes in cold climates. Bolling and Mathias [5] compared four heating and cooling systems in the aspects of the entire life cost, energy usage, exergetic efficiency and exergy destruction for the same residential house located in four different cities in America.

The four systems include a high efficiency furnace and electric air conditioner, a ground source heat pump, an absorption air conditioner and direct heating and a thermally driven heat pump; the last two systems use solar thermal energy and backup non-renewable energy.

The results showed that vertical ground source heat pump paid back in the shortest time. The construction and laboratory experiments on zero energy houses are a costly method to explore potential variations in building designs. Computer simulations of building systems can provide convenient and quick prediction for zero energy house design and avoid large costs due to building construction and experiments.

Energy Plus models hourly energy consumption in multi-zone buildings based on detailed designs and weather data, while TRNSYS has been widely applied for both energy efficiency and renewable energy analyses. The latter models each component in the system as a module and allows access to the source code for appropriate adaptation. In India, the concern for energy scarcity and the environmental problems associated with the consumption of energy in the building sector has resulted in continued interest in energy efficient building design.

The RETREAT, built as a model training complex with a built-up area of sq meters, demonstrates efficient utilization of energy, sustainable and integrated use of both natural resources and clean energy technologies, and efficient waste management systems [TERI ; TERI ]. It has established that zero energy in — zero waste out buildings could be created and run efficiently in the country.

The building has been designed as south-facing for the winter heat gains. Deciduous trees have been panted on the southern side of the complex which protects the building from the summer sun, and in winter, by shedding their leaves, the trees brighten up the rooms and provide the required heating.

The south side of the structure is partially sunk into the ground to reduce heat gains and losses. Instead of the conventional grid electricity, the complex has a PV-Gasifier hybrid power plant. The biomass gasifier generates 50 kW power by burning twigs, branches, straw and crop residue and a 10 kW roof integrated PV system generates power from solar energy.

To avoid conventional air conditioning methods, an earth tunnel system has been constructed that collects. The air conditioning of the conference hall and other common facilities is achieved by using gas-fired ammonia absorption chillers, which consume 75 percent less electrical energy than a conventional system, as well as being cleaner and CFC chlorofluorocarbon free.

Available renewable energy The volume of the cubes represent the amount of available geothermal, wind and solar energy in TW, although only a small portion is recoverable. The small red cube shows the proportional global energy consumption.

With increasing degradation of the environment because of increased energy consumption, environment conscious building design has become urgent. The benefits of green design to society in general, and building owners and users in particular, are manifold. The construction of such buildings results in reduced destruction of natural habitats and bio-diversity, reduced air and water pollution, less water consumption, limited waste generation and increased user productivity.

The cost differential between passive and conventional systems is hard to determine, as passive elements are an integral part of the building architecture. However, it is believed that passive design could prove to be a cost effective solution and should not cost more than 15 to 20 percent of the total building cost. What is needed now is to educate society about energy conserving concepts and motivate architects and builders to. The sector is a promising one and is expected to develop further at a faster rate with the active cooperation of architects, engineers, builders and policy makers.

The whole design process can be summarized into three steps. Firstly, an analysis of local climate data is of primary importance in order to make use of the local climate condition for promoting zero energy homes. Secondly, the application of passive design methods and advanced facade designs to minimize the load requirement from heating and cooling through building energy simulations. Finally, through the use of TRNSYS to investigate various energy efficient mechanical systems and renewable energy systems including photovoltaic, wind turbines and solar hot water system to enable system design optimizations.

Leadership in Energy and Environmental Design

Buildings must, at a minimum, offset all of their energy consumption with on-site generation from renewable resources. Grants will be paid incrementally, with full payment contingent on actual building performance. The program goal is to encourage exemplary buildings that bring together beautiful design and careful construction to maximize energy efficiency, showcase renewable energy and, by educating the public and professionals, help pave the way for a larger shift in the building sector. The Foundation aims to fund projects that demonstrate that net zero energy buildings are realistic and achievable.

Green Building Council USGBC it includes a set of rating systems for the design, construction, operation, and maintenance of green buildings , homes, and neighborhoods which aims to help building owners and operators be environmentally responsible and use resources efficiently. JD Polk co-founder of Solar Cells Inc First Solar also contributed to the guidelines set forth in the initial formation, as did long time solar advocate Lawton Chiles the Governor of Florida at the time. As founding chairman of the LEED Steering Committee, Watson led a broad-based consensus process until , bringing together non-profit organizations, government agencies, architects, engineers, developers, builders, product manufacturers and other industry leaders.

Although the definition of ZEB still lacks a national building code and international standards, the number of ZEB projects is still increasing worldwide which seems to be the pioneer ZEB buildings. However, due to the intermittency of the renewable resources, various uncertain parameters, and dynamic electricity price from the grid, how to select the renewable energy system for buildings is one of the challenges and therefore becomes an extensive concern for both researchers and designers.

Green Building Standards and Certification Systems

They provide some of the most effective means to achieving a range of global goals, such as addressing climate change, creating sustainable and thriving communities, and driving economic growth. Highlighting these benefits, and facilitating a growing evidence base for proving them, is at the heart of what we do as an organisation. The benefits of green buildings can be grouped within three categories: environmental, economic and social. Here, we provide a range of facts and statistics from various third-party sources that present these benefits. One of the most important types of benefit green buildings offer is to our climate and the natural environment. Green buildings can not only reduce or eliminate negative impacts on the environment, by using less water, energy or natural resources, but they can - in many cases - have a positive impact on the environment at the building or city scales by generating their own energy or increasing biodiversity.

Reduction of energy consumption of buildings is an important step in the move towards a sustainable economy. How can buildings be made net zero energy, in different climates? This course introduces you to zero energy design. It will teach you a stepped approach to design a zero energy climate concept for existing buildings: homes, schools, offices, shops etc. It will demonstrate how an integrated approach, which takes into account both passive measures such as thermal insulation and sun shading and active measures such as heat pumps and photovoltaic panels , can deliver the best results. It will do so by providing you with an overview of possible measures, and through reviewing several case studies of zero energy buildings in the Netherlands, with lessons for other climates as well. Thus, you will learn which measures are most suitable for individual buildings under local climate conditions.

Рабочим местом Джаббы была платформа, с которой открывался вид на подземную сверхсекретную базу данных АНБ. Именно здесь вирус мог бы причинить наибольший ущерб, и именно здесь Джабба проводил большую часть времени. Однако в данный момент у него был перерыв и он поглощал пирог с сыром и перцем в круглосуточной столовой АНБ. Джабба собирался взять третий кусок, когда зазвонил мобильный телефон. - Говорите, - сказал он, быстро проглотив пирог. - Джабба, - проворковала женщина в ответ.  - Это Мидж.


As a result of advances in construction skills, renewable energy systems, and academic research, creating Net Zero Energy buildings is becoming more and more.
