    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.

    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.

    Qualified transit routes must meet the following: Paired route service (service in opposite directions) Only trips in one direction are counted Only count a single stop for each route

    Projects served by two or more transit routes such that no one route provides more than 60% of the prescribed levels may earn one additional point, up to the maximum number of points.

    If existing transit service is temporarily rerouted outside the required distances for less than two years, the project may meet the requirements, provided the local transit agency has committed to restoring the routes with service at or above the prior level.

    A project is planned for an urban site. Which of the following situations might qualify for Access to Quality Transit? (select 1):

    1. A pedestrian would have to cross a busy interstate to reach 2 bus lines that stop 1/4 of a mile away.

    2. A pedestrian can walk to 2 bus stops for the same bus line, both within walking distance.

    3. A pedestrian-accessible commuter train stop will be built 1/2 mile away, within 1 year of the projects completion.

    light pollution

    waste light from building sites that produces glare, is directed upward to the sky, or is directed off the site. Waste light does not increase nighttime safety, utility, or security and needlessly consumes energy.

    SS Credit Light Pollution Reduction

    SUSTAINABLE SITES:

    Strategies & Terms Responsible Party

    The lighting boundary, similar to the LEED project boundary or property line, can vary from these other defined areas, as special considerations (such as abutting public walkways) can allow for limited expansion of the eligible site (generally making trespass requirements easier).

    Adopt site lighting criteria to maintain safe light levels while avoiding off-site lighting and night sky light pollution.

    Minimize site lighting where possible, and use computer software to model the site lighting.

    Technologies to reduce light pollution include full cutoff luminaires, low-reflectance surfaces and low-angle spotlights.

    Uplight and Light Trespass assessments may use different methods (Option 1 or Option 2) to determine compliance.

    Some lighting is exempt: Specialized signal, directional, and marker lighting for

    transportation Faade lighting used in MLO lighting zones 3 or 4 which is

    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.
