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.

Visual Arts- Wenda Gu and Shayne Higson Essay Discuss how cultural experience informs the practice of artists, art critics, art historians and/or curators. The influence of cultural experiences from different worlds has altered artists perceptions on their concept of depicting art, which is displayed in their series of artworks. Artists including Wanda Gu, Shawnee Higgins and William Gentrified demonstrate various aspects Of the cultural world they live in such as their background, shown through their artists practice. Wanda Gu questions the distinction between cultural languages, race and gender in his artworks United Nation, 2001 and Forest of stone steles, 1993-2003. Similarly, William Gentrified offers his experiences through the distinction and separation of people by their skin colors shown in his artworks Procession of the dispossessed, 1983 and Procession in the landscape with highest, 1989. While Shawnee Higgins demonstrates her cultural world through her real life experience of the political issue that is occurring in Australia which is emerging in her artworks Unsuitable, 2000 and Give me Warmth, 2004. These artists cultural experience significantly informs their practice through their artworks. Wanda Gu was born in china and graduated from the Shanghai school of Arts in 1979. He gained interest in the creation of unreadable calligraphy as he relates it to his lack of understanding towards most seal-style characters. Gu began to establish fake Chinese characters since he became inspired by the mistake he made, which lead him into creating an artwork that challenges the traditional medium through its monumental size and false ideograms. His idea was to contrast it to the controlling traditions However his artwork was not accepted to be revealed to the public as it showed no political messages like propaganda that benefits Chicanes society. Due to his countries rejection, Gu left for America where he loud actually experiment with his interests. Wanda Gu explored many issues relating to the concerns Of cross cultural understanding and the changing Of world cultures in response to globalization. These concepts are being displayed in his artwork United Nations, shown in the National gallery Of Australia; where Gu uses human hair from different country and assemble into translucent wall that is designed specifically for a country. The installation allows the audience to interact with the artwork as they deconstruct Guys idea and what he is trying to express. There was various way of interpreting his work, during that time lobar issues affect the way people decoded the armor. According to various countries, hair was seen as either their soul or a representation of power, while its color reflects the multiculturalism in Australia. The installation also consists of scrolls that have a combination to Chinese seal script and other countries character, hung above the translucent screen, that was aim to provoke questions on cultural and racial divides. Another addenda Guavas installation Forest to stone steles is set up by having stone slabs being place on the floor and 162 ink rubbings all around the walls. These pieces have calligraphers that he has once again created to challenge the notion of translation. The audience could easily misinterpret the characters as they are unreadable thus only shows the lack of cultural understanding. He uses script to give an idea of how he felt towards his cultural experiences through the importance of languages as it displays identity from individuals style of writing. Chicanes controlling tradition in art had shaped Wanda Guys concept of depicting identity as he questions it through text using calligraphy relating it to issues like translation and globalization.
