We lack a common understanding or a common definition for the†¦show more content†¦Achieving a ZEB without the grid would be very difficult, as the current generation of storage technologies is limited. Off-grid buildings cannot feed their excess energy production back onto the grid to offset other energy uses. As a result, the energy production from renewable resources must be oversized at all times. In many cases (especially during the summer), excess generated energy cannot be used. Assumption: We assume that excess on-site generation can always be sent to the grid. However, the grid may not always need the excess energy. In this scenario, on-site energy storage would become necessary. Selecting the best technology from available Supply-Side renewable energy Technologies Typical examples of various supply-side renewable energy technologies available for ZEBs today include PV, solar hot water, wind, hydroelectric, and biofuels. All these renewable sources are favorable over conventional energy sources such as coal and natural gas, but their relative preference depends upon the availability of the technology within the building footprint or at the site. Table 1 shows this ranking in order of preferred application. The principles applied to develop this ranking are based on technologies that: †¢ Minimize overall environmental impact by encouraging energy-efficient building designs and reducing transportation and conversion losses †¢ Will be available over the lifetime of the building †¢ Are widely available and can beShow MoreRelatedWhat A Net Zero Energy Building?2304 Words   |  10 PagesThe Department of Energy is continuing its efforts to collect, study and improve upon its Net Zero Energy efforts. With the continuous increase in energy use by commercial buildings, and the ample amounts of new buildings being constructed each year with little â€Å"retirement† of old buildings, the DOE is looking for options/best practices for the future. The overall purpose of this article is to deliver insight into the DOE efforts in realizing cost effective net zero energy buildings.

Traditional buildings consume as much as 40% of the primary energy consumed worldwide and are major contributors for greenhouse gases. Hence, with the intention of reducingRead MoreThe Price to Become Green1280 Words   |  5 Pagesno significant difference between the price of normal homes and zero carbon homes. It is believed that green buildings are considered to be expensive as usually all kind of new modern building methods tend to be more expensive, according to my questionnaire this is also true. I noticed that 60% of the people I interviewed thought that zero carbon homes were to be ridiculously expensive. However, it would be beneficial to have a zero carbon home as the increased initial costs offset the decreasedRead MoreGlobal Warming And The Depletion Of Non Renewable Resources3186 Words   |  13 PagesEmergent Communities A Pathway To Net Zero Energy Kara Boboski Abstract: This paper discusses the issues of global warming, and the depletion of non-renewable resources, and how it has lead to the promotion of net zero energy communities. There are many benefits to achieving carbon neutrality, which will be further explored. A wide variety of clean energy is available, which can be harnessed and even stored for future use. This variety of clean energy no negative effect on the earth.

The design strategy for energy-efficient buildings is based on climate analysis, the main benchmark to define criteria design, in order to reduce the usage of non-renewable energy (Boeri, A.
