Table 1: Maximum Acceptable Equivalent Sound Level 2.4 Ecological Balance Equivalent Sound Level at some common locations is indicated in the table below: Ecology is the scientific study of the relations that living organisms have with respect to each other and their natural environment. Variables of interest to ecologists include the composition, distribution, amount (biomass), number, and changing states of organisms within and among ecosystems. Biodiversity is the variety of life and its processes. It includes the variety of living organisms, the genetic differences among them, the communities and ecosystems in which they occur, and the ecological and revolutionary processes that keep them functioning, yet ever changing and adapting.

7.1 The Living walls as an Approach for a Healthy Urban Environment Architects Henry Browne and Borja Huidobro have built the National Insurance building in Las Condes, Santiago, Chile. The building has various eco-friendly features that made it a sustainable one. One of the features is its interior and exterior thermo panel’s vegetation that absorbs the heat of the sun. Another great green feature it has is its front wall that turns into a vegetable garden of around 3000 square meters vertical, wherein the plants changes into different looks over the years depending on the season as shown in figure. The proposal is based on the a few articles that have contributed and thrown light over this subject

The Genzyme Center is an example of a company doing the right things and this building was chosen as an AJA Top Ten Green Project for 2004. The goal of the design was to develop a building from the inside out, from the individual working environment to the overall complex structure of the building. There are eighteen gardens contributed to the green building concept. The building act as a living organism that would provide a connection to the outside through a visual connection with the outside, to look outside at the green and to bring that green into the building through the gardens and it was a high level of commitment to include the interior plants because it was the right thing to do for a green building as shown in figure. Interior planting in this building has mostly been met with a positive response. The air quality in the buildings is excellent, the shading and air-conditioning functions and also the aesthetic effect indoors are viewed positively. In administrative buildings, the number of staff off sick has decreased the individuality of the workplace plays a role here. high level of commitment to include the interior plants because it was the right thing to do for a green

Table 3: Summary of Sound Absorption Coefficient However, due to the high cost of installation and maintenance, vertical greenery systems should not be chosen only for acoustics consideration. There are other wall facades like plastering and gypsum board which are more economic. Lastly, to obtain a reasonable insertion loss, care must be taken to ensure that there are no empty gaps within the vertical greenery system which allow transmission of noise without significant absorption or scattering. 2 dB to 3.9 dB. However not all vertical greenery systems exhibit a good noise reduction. From Table 2, VGS 2, 7, 5, 1 and 6 have a reduction of around 5—10 dB for low to middle frequency range (zone B). This acoustics reduction is perceptible or even clearly noticeable for human perception in the change of sound intensity. In the high frequencies (zone D), VGS 8 clearly outperforms the rest with a highest insertion loss of 8.8 dB. The rest of the vertical greenery systems have an insertion loss ranging from 9 dBto 3.9 dB.
