Leadership in Environmental and Energy Design (LEED®) is a rating system for assessing environmental performance of buildings. It is administered by the non-profit group, U.S. Green Building Council (USGBC). By establishing a common standard of measurement, LEED® provides a complete framework for assessing building performance and meeting sustainability goals.
Benefits of Sustainable Offices:
Currently, buildings are responsible for 33 % of total annual energy used in Turkey. Buildings also account for significant portions of fresh water consumption during both construction and occupancy. Material waste during construction accounts for up to 45 % of landfill, depending on location. A carefully designed, sustainable building operates to reduce impact on the environment while providing financial and health-related benefits for the Owner and Tenants.
One important issue, from which tenants benefit most, is the comfortable, controllable environmental design of sustainable buildings. The impact of such an attribute shall result in increased employee retention. “Green,” or sustainably designed buildings not only reduce consumption of energy, fresh water and materials, but also provide a comfortable, healthy indoor environment for the occupants.
The quality of the workplace has impact on both direct and indirect costs to an organization. Direct costs such as utilities and waste disposal or treatment are often passed on to the tenant. Indirect costs, such as non-productivity or sick-leave (the maximum amount of non-productivity) are borne by the tenant. When improvement in the workplace results in increased productivity and reduced direct cost, the result is profit for the Tenant.
Office worker salaries are typically the largest operating expense for a business. Therefore, a small rise in productivity may generate huge savings. Productivity, retention and reductions in absenteeism are usually related to the high quality of workspaces, which are comfortable and safe.
Most common complaints effecting tenant comfort, health and satisfaction are:
• Poor indoor air quality, lack of fresh air
• Poor lighting
• Distractions such as Noise or Odors
Some common complaints result from psychological factors such as:
• Lack of control over switches, thermostats etc.
• Lack of contact to the outside (view, daylighting)
A workplace that addresses issues of comfort and satisfaction can attract potential employees. Employees will be less likely to be affected with physical complaints or “sick building syndrome” and related employer liability is therefore reduced.
WHAT CAN BE PRACTICED AT HOME?
Several strategies were followed in order to use water more efficient in AND which can be practiced at home as well, such as :
– Water efficient fixtures can be used in bathrooms
– Reuse of gray water from lavatory faucets and showers for reservoirs reduce potable water consumption
– Choice of less water consuming vegetation and reuse of rainwater for irrigation are also effective strategies for water conservation in the building
RECYCLABLE WASTE MANAGEMENT
Recyclable waste can be separated at home as in AND which is explained below:
– Recyclable waste generated on each floor will be collected and transported to the main area. A recycling waste company is contracted to collect these waste.
– This strategy will reduce the amount of waste disposed from the building into local landfills.
– Recyclable waste materials include: paper, cardboard, glass, plastic, and metals.
– All tenants are encouraged to promote recycling programs within their tenant spaces.
Energy efficient lighting fixtures can be chose at home and façade isolation such as façade glass performance values can be improved. AND C&S building’s envelope, HVAC system, and lighting were designed to optimize energy performance of the building.
– This building complies with the mandatory provisions and prescriptive requirements of ASHRAE 90.1-2007 which is beyond Turkish local standards.
– An energy model of the proposed building was developed and energy performance of the building was analyzed by running simulations on that model. This model can be developed further by integrating the design criteria for each tenant.
– Interior Lighting Power Density values must be 20% less than values shown in ASHRAE Table 9.6.1 and lighting fixtures must be chosen according to these values.
The environmentally sensitive management plan will be in place for the site’s natural components. The plan employs best management practices that significantly reduce harmful chemical use, energy waste, water waste, air pollution, solid waste and/or chemical runoff compared with standard practices. The plan addresses the following operational elements:
– Diversion of landscape waste from the waste stream via mulching, composting or other low-impact means.
– Chemical fertilizer use. The use of artificial chemicals can be minimized by the use of locally adapted plants that need no fertilizer, less-polluting alternatives to artificial chemicals, or other low-impact maintenance practices.
INDOOR ENVIRONMENTAL QUALITY
Choosing low VOC content adhesives, sealants, paints and coatings for our home is an important practice for our health. Other IEQ applications which AND has made:
– Smoking is prohibited inside the building. Dedicated smoking spaces are beyond 25 feet of entries, outdoor air intakes and operable windows.
– VOC content of adhesives, sealants and interior paints used in the core& shell areas comply with referenced standards in LEED rating system. Tenants should incorporate a plan to avoid use of construction materials and furniture with high VOC limits.
– Core & Shell AND building provides the required infrastructure for lighting systems to be individually controlled.
– Building fenestration was designed in order to provide sufficient daylight and views for everyone in the offices and regularly occupied areas.
You can reduce your carbon footprint with the use of public transportation, carpooling or cycling…
AND is located in a commercial district which provides different benefits such as easy access to public transportation, and numerous facilities and services in close proximity. These opportunities will eliminate the need for personal car use which is an important environmental issue.
Additionally, several strategies such as provision of bicycle parking areas and preferred parking for low emitting vehicles were implemented in order to reduce negative effects of personal car use further.
