Ch. 16 - Sustainability and the Built Environment

What does the acronym LEED stand for?

Leadership in Energy and Environmental Design

What is the triple bottom line?

Measurement of business success by the financial performance of the organization as well as the environmental and social factors

6 Fundamental Principles of Sustainable Building Design

1 - Optimize Site Potential 2 - Optimize Energy Use 3 - Protect and Conserve Water 4 - Optimize building space and material use 5 - Enhance indoor environmental quality 6 - Optimize operational and maintenance practices

According to the EPA buildings in the US account for:

39% total neergy use 68% total electricity use 12% of total water use 38% of all CO2 emissions 60% of thr total non-indistrual waster generated

8 common types of environmental performance measurements?

Air quality Water quality Water usage Electricity consumption Fossil fuel consumption Recycling trends Hazardous waste quantities Air and water pollutants Health impacts

Name three ways we can reduce and optimize energy use.

Among ways to reduce energy use are to reduce heating, cooling, and lighting demand through passive strategies such as daylighting and conservation practices; specify energy-efficient HVAC and lighting systems; utilize and install energy-efficient appliances and products displaying the Energy Star designation; employ renewable energy sources such as solar heating for hot water, photovoltaics, and geothermal heating systems; optimize building performance by employing energy modeling programs during design and after occupancy and operations; optimize system control strategies by using programmable thermostats and other occupancy sensors.

Green Building Materials

Basic materials that may be the components of products or used in a stand-alone manner in a building. Green building materials have low environmental impact compared to the alternatives.

How can construction waste be eliminated?

By recycling, reusing, and eliminating waste.

LEED Certification Levels

Certified, Silver, Gold, Platinum

Define life-cycle cost analysis (LCCA).

Determining the most cost-effective option among different alternatives

What is the life-cycle of building products?

How materials are extracted and processed, manufactured and shipped, purchased and used, repaired and maintained, and disposed of.

How do buildings earn LEED certification?

It must earn money points by meeting certain criteria. Based on the total number of points achieved, a project then achieves on of four LEED rating levels.

What are the six fundamental principles of sustainable building design?

Optimize site potential Optimize energy use Protect and conserve water Optimize building space and material use Enhance indoor environmental quality Optimize operational and maintenance practices

Product Life Cycle

Raw Materials Manufacture Transport Purchase Use & Maintain Disposal

Name 6 types of green materials?

Recycled content Reclaimed material Low-Emitting Materials Certified Wood materials Rapidly renewable materials Locally/Regionally sourced materials

Optimize Site Potential

Smart placement with existing natural terrain Taking a advantage of sun

Leadership in Energy and Environmental Design (LEED)

The U.S. Green Building Council (USGBC) LEED green building program is the preeminent program for the design, construction, maintenance, and operation of high-performance green buildings.

Life-Cycle Cost Analysis

a method of determining the total cost of a building, building component or system over a period of time. Allows two or more alternatives to be evaluated and their total costs to be compared.
