Green Building The increase in interest in the environment has lead to innovations in building design in general and has also affected the skyscraper. In some instances these innovations are made in collaboration with the other five innovations such as structure, and section and are visibly noticeable as part of the generation of the buildings form and section. But in most cases the innovations are less visually dramatic but no less transforming.
Why Go Green ? • Buildings that are built to be sustainable, or energy independent, are not as dependent on the grid and therefore aren't levered to the cost of energy (such as the price of coal, nuclear energy, or even other alternative sources provided into the grid).
Why Go Green ? 1.Buildings that are built to be sustainable, or energy independent, are not as dependent on the grid and therefore aren't levered to the cost of energy (such as the price of coal, nuclear energy, or even other alternative sources provided into the grid). 2. They leave a lighter footprint on the earth and its atmosphere--zero energy buildings are the epitome of natural resource frugality.

They can be healthier to live in. 4. The operating costs of this type of building are optimized and likely to be minimal when compared to non-sustainable buildings.
Commerzbank, Frankfurt, Germany, Norman Foster “The building should use ambient energy as much as possible to reduce the amount of fossil fuel derived power; users should be exposed to the beneficial effects of contacts with plants, and individuals are to have the possibility of opening their windows to be able to obtain fresh air, even on the highest floors”. Norman Foster
Consumption was lowered • A combination of building orientation and high-performance envelope, day lighting and control systems. By rotating to the east, the tower takes advantage of midday sun while the effects of late-day sun on the larger, southern horizontal exposure are minimized. The south facade’s low-E-glass, double-layer curtain-wall system reduces heat gain, which leads to less demand on the HVAC systems.
Consumption was lowered • The tower reclaims its energy by routing each floor’s exhaust air into the south side’s double-layer curtain-wall cavity. This thermal barrier of hot dry air can then be reused on the mechanical floor for passive dehumidification.
Consumption was lowered 3. The building uses a chilled slab concrete vaulted ceiling in the typical offices this enhances day lighting, as well as cools the air drifting up from the under floor ventilation system.
Consumption was lowered 4. The main absorption strategy takes advantage of a geothermal heat sink, so 100 degrees Fahrenheit water in the mechanical system’s return loop can be cooled to 75 degrees Fahrenheit prior to feeding the cooling towers.
Energy Generating Strategies • Wind • Photovoltaic • And micro-turbines
Strategies Include • Social Sustainability 2. Environmental Sustainability
Social Sustainability • Opportunities for local employment through mixture of use, both on ground and upper levels. This includes housing, retail, leisure, communal facilities and commerce on the retail levels and up the tower. The location of housing in close proximity to employment, retail, leisure and community facilities will reduce reliance on public transport.
Social Sustainability • A healthy mix of residents within the same building. Through "vertical zoning", resident types are grouped according to accommodation preferences (single units, family units, luxury apartments), yet common facilities (e.g. parks, shopping streets etc.) are shared.
Social Sustainability • Close proximity to basic amenities, such as the local grocery store, postal boxes, chemist etc. These are all located within the ground development and/or within the tower.
Social Sustainability • Mixture of residents from different ages, occupations and family structures are accommodated by the provision of a variety of accommodation types: studio apartments 2-room apartments Penthouses.
Social Sustainability • A healthy landscaped environment, with spatial progressions of public open spaces (parks in the sky) to semi-private (entrance courts) to private open spaces (balconies). The design seeks to re-create conditions on the ground up-in-the-sky, with features such as an entrance lobby, light wells and balconies for every unit and shared secondary and tertiary landscaped open spaces and sky pods within groups of housing in the form of sky courts and communal pods.
Social Sustainability • Urban connectivity is a key concept in the design proposal. The proposal here includes a high level bridge over the proposed railway station and direct connections onto the garden terrace and into the retail zones.
Environmental Sustainability 1. The Building’s external interdependencies, consisting of the designed system's relations to its external environment and ecosystems.

External Dependencies Site Eco System Its urban condition meant that the site was essentially a devastated ecosystem with little of its original topsoil, flora and fauna remaining. • increase biodiversity and organic mass • The provision of a park over the land • A system of continuous planting up the towers (as "vertical landscaping")
