V4 Green Associate Test 1 (Part 4)

Question 80 Explanation:

Granite is naturally occurring with no VOCs. VOCs are substances that vaporize at room temperature and can cause health problems. VOCs off-gas from many materials, including adhesives, sealants, paints, carpets, and particle board

Question 81 Explanation:

Regenerative design is 'sustainable plans for built environments that improve existing conditions. Regenerative design goes beyond reducing impacts to create positive change in the local and global environment.' - USGBC By generating more electricity than the project uses, the system is considered regenerative.

Question 82 Explanation:

On-site restoration involves restoring compacted soils and revegetating. The others help with rain water management or increasing open space.

Question 84 Explanation:

Although not the best option especially for LEED, HCFC were the first refrigerant to replace CFCs.

Question 85 Explanation:

Prerequisites and MPRs must be met regardless so they are not the answer.

Question 86 Explanation:

When calculating indoor water-use baselines or design cases, the calculations are based on the number of occupants in the building using the fixtures.

Question 87 Explanation:

Projects in an urban site with a zero lot line (the building footprint is on the site limit) will have to use green infrastructure (GI) and low-impact development (LID) rainwater management strategies since there is no land.

Question 89 Explanation:

With Building Disclosure and Optimization remember there are two parts - the disclosure and the optimization. The disclosure is about transparency, which includes environmental product declarations (life-cycle impacts), material ingredients (health product declarations), and raw materials sourcing (corporate sustainability reports). The optimization is about using a certain quantity or percentage of those products that have disclosure for the project. Optimization usually includes a third party certification for the product. For material ingredients those certifications are GreenScreen and Cradle-to-Cradle Certified. Choosing products that have met one of those standards helps earn the credit. For international projects REACH Optimization can be used instead.

Question 90 Explanation:

Building Automation Systems (BAS) are systems that use computer controls to monitor and control building subsystems for maximum operating efficiency and reporting. There are additional options that can identify problems that should be addressed by the facilities manager: • Building-Level Energy Metering supports energy management and identifies opportunities for additional energy savings by tracking building-level energy use. • System-Level Energy Metering supports energy management and identifies opportunities for additional energy savings by tracking building-level and system-level energy use. • Ongoing commissioning (aka recommissioning) is a type of commissioning that occurs when a building that has already been commissioned undergoes another commissioning process. The decision to recommission may be triggered by a change in building use or ownership, the onset of operational problems, or some other need. Ideally, a plan for ongoing commissioning is established as part of a new building’s original commissioning process or an existing building’s retro-commissioning process. Enhanced Commissioning is an extension to the original commissioning process that, among other things, reviews building operations 10 months after substantial completion and develops an ongoing commissioning plan. Recommissioning (aka Retro-commissioning ) is the application of the commissioning process to existing buildings.

Question 91 Explanation:

This strategy maximizes a building's ability to use natural lighting and natural heating.

Question 92 Explanation:

Demand response (DR)is a program where the utility company contacts a consumer with a request to cut back on their power draw during a curtailment event (e.g. Severe weather, heavy load on the grid, utility company maintenance). DR is simply a contract agreement between the utility company and consumer (usually large commercial or industrial) and not a form of alternative or renewable energy. Renewable energy production is the generation of onsite renewable energy, which protects projects from energy price volatility and reliance on the grid. It also allows the project to achieve net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is roughly equal to the amount of renewable energy created on-site. Renewable energy sources allowable include: Biofuel, wave and tidal energy, wind, low-impact hydroelectricity, geothermal, photovoltaic, and solar thermal. Renewable Energy Certificates (RECs)are tradeable, non-tangible energy commodities. RECs represent proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource (renewable electricity). Green power may be purchased either directly or indirectly from utility providers, and while some utility providers actually deliver green energy through the grid, many purchase RECs. Carbon Offsets are reductions in emissions of carbon dioxide or greenhouse gases made in order to compensate for or to offset an emission made elsewhere. In the voluntary market, individuals, companies, or governments purchase carbon offsets to mitigate their own greenhouse gas emissions from transportation, electricity use, and other sources. One carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases. RECs allow buildings that use nonrenewable power to create market demand for renewable energy while carbon offsets allow buildings to fund activities that decrease carbon emissions or remove carbon

Question 93 Explanation:

Smart growth is developing in areas near transportation, housing, and jobs in order to leave open spaces and farmland free from development. A site far away from existing development is probably a Greenfield.

Question 94 Explanation:

Stone and wood are not well suited nor are materials from overseas. LEED entryways should be grills, grates, or mats to help clean people's shoes off as they walk in. This keeps dust/dirt/contaminants out. The low VOC material is the best choice available.

Question 95 Explanation:

Metrics and measuring for success are part of the integrative process. While the integrative process continues until the building's end-of-life - not at project handover.

Question 97 Explanation:

The fact that it states apartment gives away that we are asking about a private faucet’s flow rate

Question 98 Explanation:

The WE section is based on an “efficiency first” approach to water conservation. As a result, each prerequisite looks at water efficiency and reductions in potable water-use alone. Then, the WE credits additionally recognize the use of non-potable and alternative sources of water. In the Indoor Water Use credit, these alternative water sources are permitted: • municipally supplied reclaimed water • graywater • rainwater • stormwater • condensate • foundation • dewatering water • used process water • reverse osmosis reject water Untreated water sources ineligible for this credit include: • raw water from naturally occurring surface bodies of water • streams, rivers • groundwater • well water • seawater, etc.....

Question 99 Explanation:

Some of the obstacles teams face with people new to green building include: •The costs and time to hold meetings •Resistance to green goals •Resistance to the integrative process •Not being familiar with the approaches suggested •Getting people to use the modelling tools

Question 100 Explanation:

To determine the quality of the water, a water test would need to be done.

Question 101 Explanation:

Transportation demand strategies that can reduce single-occupancy vehicle use include: • Locating a project near public transportation • Encouraging carpooling • Encouraging walking or bicycling • Providing preferred parking for green vehicles • Discounted transportation passes for buses, rails, ferry's, etc. • Telecommuting • Compressed workweeks
