GREEN ARCHITECTURE IN CORPORATE OFFICES

Slide 2: 

PERCEPTION GENERAL PERCEPTION OF THE PUBLIC Most people’s perception of a “green building”. Perception that green building doesn’t incorporate beautiful design. People think it costs more.

Slide 3: 

REALITY REALITY OF GREEN DESIGN Reality of green design in market. Designing green building doesn’t sacrifice on amenities. Green design can be functional, urban and modern.

Slide 4: 

WHAT IS GREEN ARCHITECTURE AND DESIGN? site planning Indoor environmental quality material use water management energy performance Design and construction practices that meet specified standards to reduce the negative impact of buildings and tenant spaces on occupants and the environment. (USGBC) A green building uses less energy, water and natural resources, creates less waste and is healthier for the people living inside compared to a standard building. (IGBC)

Slide 5: 

When the well is dry, then we know the worth of water. - Benjamin Franklin THE PREMISE FOR GOING GREEN The world’s resources and ecosystems are increasingly being stretched, and buildings currently account for; 36% of total energy use 65% electricity consumption 30% of green house gas emissions 30% of raw materials use 30% of waste output 12% of potable water consumption

Slide 6: 

GREEN MOVEMENT AND USGBC Introduction Role of USGBC LEED system Levels of LEED ratings Categories of LEED ratings LEED rating system certification levels Robert Watson, scientist for NRDC (Natural Resource Defense Council) chaired the first LEED Green Building Rating System meeting for USGBC. Green building concepts were mostly ignored until early 2000’s. The main reasons for green building concepts was climate change and global warming. USGBC , a national, nonprofit organization founded in 1993. Developer and administrator of the LEED (Leadership in Energy and Environmental Design).

Green office

Slide 31: 

What is a green office? What a green office offers Save by being green Energy efficiency Indoor air quality Resource efficiency GREEN OFFICE A green office saves money, is a healthy place in which to work, and is environmentally friendly. A green office is Ecological (using non-toxic, recycled, environmentally friendly products and supplies). Efficient (using as little energy and resourced as possible). Healthy (with good indoor air quality and small amounts of visual and noise pollution). Helps the environment by putting out the smallest amount of waste possible.

Slide 32: 

What is a green office? What a green office offers Save by being green Energy efficiency Indoor air quality Resource efficiency GREEN OFFICE Increase productivity - healthy work places have been shown to raise employee productivity by more than 10%. Reduce expenses – by reducing energy demand and office supply waste. Improve public relations Environmentally proactive companies have shown 4% higher rate of return. 9% higher sales growth. 17% higher operating income.

Slide 34: 

What is a green office? What a green office offers Save by being green Energy efficiency Indoor air quality Resource efficiency GREEN OFFICE Lighting Daylighting reduces the need for electric lights lowering internal heat gain. Proper glazing reduces solar heat gain. CFLs burn at lower temperatures than incandescent lamps. Improve lighting controls and educate users to turn off unneeded lights. Perform simple maintenance. Sunlight should be reflected and diffused deep into interior spaces. Motion sensors are useful in spaces that are infrequently used.

Slide 35: 

What is a green office? What a green office offers Save by being green Energy efficiency Indoor air quality Resource efficiency GREEN OFFICE Lighting Light sensors are useful for spaces with windows or skylights. CFL uses 75% less energy than standard incandescent lamps. Use low-mercury lamps as they are not classified as hazardous waste. Office Equipments Equipments with energy star label saves money and are more efficient. Use power management devices. Power management saves money and energy.
