1. Objectives of a Green Building
What is Green Building?
A Green Building, also known as a sustainable building, is a structure that is designed, built, renovated, operated, or re-used in an ecological and resource efficient manner.
Objectives of a Green Building
Protecting occupant health,
Improving employee productivity,
Using energy, water and other resources more efficiently,
Reducing overall impact to the environment,
Optimal environmental and economic performance,
Satisfying and quality indoor spaces.

2. What is LEED?

3. LEED (Leadership in Energy & Environmental Design)
The LEED (Leadership in Energy & Environmental Design) green building certification system is the accepted program all over the world for rating the design, construction and operation of green buildings which is given by The United States Green Building Council (USGBC) since 1998 that aims to reduce greenhouse gas emissions and contribute a healthy living and work environment for residents and workers by using energy efficiently.
The rating systems can be changed for specific building typologies, sectors, and project scopes.
LEED certifications are awarded according to the following scale (0-100) :
-Certified (40–49 points),
-Silver (50–59 points),
-Gold (60–79 points),
-Platinum (80 points and above).

5. NİDAKULE LEVENT & LEED
Nidakule Levent Project achieved GOLD level certification in the Core & Shell category of LEED. In this context, numerous environment and human friendly characteristics are integrated into the project design and construction. Such as;
SUSTAINABLE LAND AND LOCATION
Selection of natural plants well-adapted to the climate of Istanbul to save water
Adequate numbers of bicycle parks with a view to encouraging alternative means of transportation and reducing the use of private cars.
Charging stations are offered to encourage the use of these more environment- friendly vehicles.
The use of lighter colored tiles and materials on the roofs, and by taking most of the parking underground, the ’ heat island impact ’ was prevented.
MATERIALS AND RESOURCES All construction materials used in the building are selected to ensure sustainability and environment-friendliness. A substantial portion of the waste produced during the construction were recycled and/or reclaimed, to minimize the amount of waste sent to disposal sites.

6. NİDAKULE LEVENT & LEED WATER & ENERGY EFFICIENCY
Rainwater and grey water systems reduce the total annual water consumption by approximately % 50 in comparison to conventional buildings.
The landscaping design makes use of plants well-adapted to the climate and consume less water. The use of tap water for landscaping is reduced through the use of rainwater and condensation systems which allows the reduction of water use more than %50.
All power-consuming systems subjected to the international commissioning and testing procedures provided by LEED. The systems checked during both assembly and use, to see if they meet the established performance criteria.
Energy efficiency is prioritized for all service systems utilized within the framework of the project. Efficient lighting fixtures, high-grade isolation materials, efficient heating and air-conditioning devices make a point of compliance with the US energy efficiency standard (ASHRAE 90.1).
Energy consumption of all systems are being monitored through power analyzers, calorimeters, and associated building power monitoring systems. The air- conditioning systems used in the project make use of environment and OZONE layer friendly refrigerants.

7. NİDAKULE LEVENT & LEED QUALITY OF INTERIORS and USER COMFORT
The construction chemicals (paint, primer, adhesives, pastes etc.) to be used interiors were selected for compliance with international limits with respect to Volatile Organic Compound (VOC) contents.
All materials used during the construction were protected from humidity, dust, and dirt, and the completed sections of the building were protected in detail, in order to ensure that a healthy and clean environment is provided to end users.
Design criteria required for the ventilation of interiors are in accordance with the standard ASHRAE The volume of fresh air fed into the building is above the requirements of American ASHRAE 62.1 standard.
The interiors thermal comfort design is compliant with ASHRAE 55 standard. Individual control over heating and lighting systems is prioritized, to increase both energy savings, and the inherent level of comfort.
