Perkins

Earth as modified by human action: man and nature

Thermal mass

Every mass retains heat and radiates it. So can heat with concrete that takes up heat during the day and radiates it at night.

"Climate Change" and "Weather Changes" are the same thing

False

What is the phases of Life Cycle Analysis as defined by ISO?

Goal Definition and Scoping Inventory Analysis Impact Assessment Interpretation (happens throughout)

The highest R-values are assigned to the materials that provide the ___________

Greatest amount of insulation and the greatest resistance to heat flow

R value

Insulation of wall, roofs and floors. has to do with capacity of a material to resist heat flow. Lower the R value, lower insulation.

Kyoto Protocol

International treaty that stated CO2 is culprit of climate change caused by humans. Nations must come together.

Why is night time light pollution a problem?

It can affect our safety as it takes time for human eyes to adjust from dark to light surroundings It limits our view of the night sky It can adversely affect sleep and migration patterns of nocturnal animals

Living Bldg Challenge vs LEED

LBC - creates more energy than it takes to zero energy voluntary certi program categories are petals higher stakes than LEED no optional credits, must do all of requirements

Why would exponential growth of the human population cause stress on the environment?

People use finite natural resources to create food and energy. As the population grows, the use of these resources (like coal) increases, thus harming the planet

solar hot water vs solar pv panels

Photovoltaic panels are solar cells built out of silicon that reacts to sun creating a positive charge that generates electricity. Solar hot water is a tube filled with gel that heats up from solar energy and heats up water to use in home.

All of the following are passive design strategy to take advantage of solar gain in the winter AND block the sun the summer:

Planting deciduous trees near windows on the south side of a building Long roof overhangs on the south side of a building Elongating a building on the east/ west axis to increase the surface area of the north/ south exposure

Porous and open grid pavement

Porous asphalt lets rain seep in and reach ground open grid uses grid pattern with cement and vegetation that allows water to reach ground

Which one single sustainable strategy in building design can have a ripple effect on all of the other needs of a building?

The size of a building affects the amount of materials needed, maintenance, embodied energy, how much energy is needed to heat, cool, and light the place, site disturbance, and more. The smaller the building, the better the environmental impact.)
