Unmoven light

This stunning installation is composed of hundred of units, which is pieces of glasses and covered with color. It is suspended from the walls and ceilings and transmits a shimmering world of light, shadow, and brillant color. The divided space are created by the twisted  sculptures that look like floating in the air. It seems the feeling that is the physical reality compares with the ideal reality when people stand in the space and always look out.

Using Skylight Instead of Electronic Lamp

Although there is not a window in the bathroom, the skylight can instead of the electronic light. At the same time, it is benefit to reduce the consumption of energy. 

My idea is to create a house that visitors cannot see the master's privacy space from outside. It means that there are not many area could let sunshine through the window. Instead, i am trying to create space on the roof in order to light the interior. Because i do not want to take advantage of too much electronic lamp.

What is the approximate cost of a green roof? How much energy does a green roof save?

• What is the approximate cost of a green roof?

The cost of the green roof is depending on which state you are in, which would range from $10 to $25 per square foot or $108 - $269 per square meter... (one square meter = approximately 10.76 square feet). More sophisticated green roof (or green wall) installations can cost from $25 to $100 per square foot, or $269-$1075 per square meter or more.(source http://www.green-buildings.com/content/78335-green-roof-cost)

How much energy does a green roof save?

According to the Center for Climate Systems Research, a comparison of a standard black tar roof and a green roof showed these results:

One square meter of black tar roof produced 500 kWh per year. 
One square meter of green roof produced 140 kWh per year. (source http://alivestructures.com/FAQ/greenroof_faq)

On average, for one story structures, a green roof saves $4.50 per square foot on an annual basis.(source http://alivestructures.com/FAQ/greenroof_faq)

Advantages & Disadvantages of The Green Roofs

Advantages

- Extended roof life: a green roof protects the waterproofing membrane from climatic extremes,   UV light and mechanical damage doubling its life expectancy.

- Provides thermal insulation in the winter and helps to cool buildings in the summer.

- Excellent sound insulation.

- Growing mediums can be made from recycled materials, such as crushed bricks.

- Reduces water run-off

- Encourages biodiversity.

- Provides attractive green spaces


Disadvantages

- Where the roof pitch is steeper than 40 degrees, a green roof is indefeasibly expensive. (cost http://lisantu2013.blogspot.co.uk/2013/12/what-is-approximate-cost-of-green-roof.html)

- Plant growth is unpredictable because of airborne seeds and those dropped by passing        birds
