By completing this course, you will be able to:
Explain the various LEED rating systems, categories, and minimum program requirements.
List the requirements, strategies and intent of each credit in LEED v4 for New Construction
Identify the core concepts and define key terms behind green building.
Differentiate between the many referenced standards used by LEED v4, such as ASHRAE Standard 90.1-2010, Green-e Energy product certification, and the California Department of Public Health Standard Method v1.1-2010.
Identify best practices for achieving a sustainable project site, such as site selection, reducing building footprint and restoring native vegetation, to reduce impact to the environment.
Learning Objectives
W H AT W I L L YO U L EA R N ?
Determine appropriate water saving strategies, such as using non-potable water and selecting water efficient fixtures, to reduce the use of municipal drinking water for non-drinking purposes.
Prioritize strategies related to energy use, such as energy efficiency, use of clean energy, and on-going operations, to maximize pay-back and diminish impact on the environment.
Relate material selection to Life-Cycle Assessment with concepts such as extending building stock, redirecting resources back to the manufacturing process, and sourcing locally harvested materials, in order to reduce the environmental impact of using virgin materials.
Explain the ways in which the building process and operations can affect a projects Indoor Environmental Quality, such as access to daylight and views and implementing an Indoor Air Quality Management Plan.

LOCATION AND TRANSPORTATION
Strategies & Terms Responsible Party
During the site selection process, give preference to that do not include sensitive elements or restrictive land types.
Select a suitable building location and design the building with a minimal footprint to minimize disruption of the environmentally sensitive areas identified above.
If possible, choose a previously developed site, therefore there is less environmental impact, since the site has already been disturbed.
When selecting a site evaluate how much land disturbance will be involved for construction and the overall developed portion of the site.
Incorporate the natural features of the site into the site development.
During design take into account what wildlife has been living on the site prior to development.

Minimize parking lot/garage size. Consider sharing parking facilities with adjacent
buildings. Credit calculations must include all existing and new off-
street parking that is leased or owned by the project, including parking outside the project boundary used by the project. On-street parking is excluded.
Projects with shared (or pooled) parking, should calculate compliance using only the projects share of the pooled parking.
Mixed-use projects should calculate compliance by first aggregating the parking amount of each use (as specified by the base ratios) and then calculating the percentage reduction from the aggregated amount.
Parking spaces for fleet or inventory vehicles are not counted unless these vehicles are regularly used by employees for commuting.

Non-US projects may use a local equivalent to the EPA WaterSense fixture labeling requirement.
Use of alternative water sources does not count for prerequisite compliance, but can contribute for the credit (beyond the first 20%).
Credit calculations factor in all plumbing fixtures used by occupants, even if some fixtures are outside the project boundary. Prerequisite calculations consider only project fixtures.

WATER EFFICIENCY:
Strategies & Terms Responsible Party
Evaporation of cooling tower water leads to build up of dissolved solids.
Makeup water is the added water to the cooling tower system or evaporative condenser to offset water lost due to evaporation and other causes.
Blowdown is the process of discharging cooling tower water to remove dissolved solids.
Increasing the number of cycles between blowdown reduces the amount of makeup water inputs.
Nonpotable sources should generally contain low levels of dissolved solids. This can include air-conditioner condensate, rainwater, steam system condensate, food steamer discharge water, fire pump test water, and ice machine condensate

Cooling Tower Water Use:SAMPLE QUESTION
QUESTION:
Water is periodically discharged from cooling towers as blowdown. Why is this necessary?
1. To avoid unsafe water temperatures
2. To prevent the formation of radioactive isotopes
3. To reduce concentrations of dissolved solids
4. To reduce formation of ice
5. Blowdown is an optional process, used to increase efficiency
