Green Buildings

Question 1

Green buildings rating systems categories

Answer 1

Site sustainability- water efficiency - energy performance - building simulation - re- sustainable building material _iaq -lighting - thermal comfort

Question 2

Basic principles of GB?

Answer 2

Sustainable site design - water conservation and quality - energy and environment - conservation of resources and reuse materials. - IEQ

Question 3

What to put in GB:

Answer 3

I-solar panels to produce building’s electricity
2- Solar thermal heating system to heat water
3- high performance thermal windows and doors that reduce heat losses and increase daylight.
4- grey water recovery to reduce waste water and water consumption to use it in toilet flushing and watering plants.
5- low flow water fixtures to reduce water usage.
6- home energy manager: control panel to control and manage energy consumption.
7- energy efficient lighting.
8 - demand response appliances: high efficiency - energy labels A.
9-geothermal or underfloor heating or cooling.

Question 4

GB benefits

Answer 4

1- reduce energy and water consumption.
2- PBP between 3 and 5 years.
3-easter sales and higher occupancy rates.

Question 5

Sick house syndrome

Answer 5

1 - carbon monoxide from incomplete combustion.
2- toxic paint that have VOCS and lead.
3- synthetic insulation.
4- bacteria from toilets.
5- construction materials / construction, dust, small particles.
6-smoke.
7- poor circulation and lack of fresh air.
8- bust mites.
9-synthetic carpet outgassing.
10 -mold and mildew,
11- pet dander.

Question 6

Mold and mildew

Answer 6

Causes: No insulation-thermal bridges- water leak- no roof inclination - leak from upper floor - no roof insulation.
Effects: rapid spread because of lack of fresh air - color changes based on type, material and temp.

Question 7

How common is mold in buildings

Answer 7

Its very common, mold grow in places with moisture such as around leaks in roofs, windows, pipes. Mold grow on paper-carboard- ceiling tiles - wood. - paint - wallpaper and carpets.

Question 10

Principle of rating system

Answer 10

• To measure the sustainability levels of GB and provide best practice experience in the highest certification level.
• it has given benchmarks, design, construction and operation.
• several criteria compiled in guide lines and checklists for building owners

Question 11

Leed rating system

Answer 11

Sustainable site-water efficiency-energ efficiency - materials and resources - IEQ - innovation in design.
40-49 -certified
