ASHRAE 90.1-2010, Appendix G is the referenced standard for defining the baseline building performance for energy simulation modeling in LEED v4 for Building Design and Construction. The baseline building is a hypothetical building that represents the minimum energy performance required by ASHRAE 90.1-2010, which is a standard for energy efficiency in buildings. The baseline building is used as a benchmark to compare the proposed design of the project and to calculate the percentage of energy cost savings achieved by the project. The baseline building performance is evaluated by following the procedures and assumptions specified in Appendix G of ASHRAE 90.1-2010, such as building envelope, lighting, HVAC systems, service water heating, and renewable energy.

The other options are not relevant to the question, as they are standards for different aspects of green building, such as thermal comfort (ASHRAE 55-2010), air filtration (ASHRAE 52.2-2007), and ventilation (ASHRAE 62.1-2010).

Minimal hardscape and permeable surfaces allow water to infiltrate, reducing rainwater runoff and supporting sustainable stormwater management strategies. These practices align with LEED Sustainable Sites goals​​.

Green power, like all electricity, is typically purchased in units of kilowatt-hours (kWh). This unit measures the amount of energy used over time. For example, a 1-kilowatt (1000 watts) appliance used for one hour consumes one kilowatt-hour of electricity. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

One of the values and benefits of building green is that it will enhance the health of the building occupants. Building green is a process that incorporates environmental considerations into every stage of a building’s life cycle, from design to construction to operation to end-of-life. Building green can improve the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants. Building green can enhance IEQ by using low-emitting materials, providing adequate ventilation, controlling temperature and humidity, optimizing daylighting and lighting quality, reducing noise levels, and promoting occupant well-being12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

A life-cycle assessment (LCA) is a strategy that can help an owner of newly acquired land design a building that uses materials that have minimal impact on the environment. An LCA is a method that evaluates the environmental impacts of a product or material over its entire life cycle, from extraction to disposal. An LCA can measure the impacts on various categories, such as energy use, water use, greenhouse gas emissions, resource depletion, and waste generation. An LCA can help compare different products or materials based on theirenvironmental performance and select the ones that have the lowest impact13. References: LEED v4 Green Associate Candidate Handbook1, EPA’s Life CycleAssessment3

Life-cycle assessment (LCA) is the approach that refers to the identification and quantification of environmental effects throughout the life of the materials and products used in a project as well as the project itself. LCA evaluates the environmental impacts of a product, process, or service from cradle to grave, or from raw material extraction to disposal or reuse. LCA considers various impact categories, such as global warming potential, ozone depletion potential, acidification potential, eutrophication potential, smog formation potential, and human health impacts. LCA can help to compare the environmental performance of different design options, select more sustainable materials and products, and reduce the environmental footprint of a project

An office without transit access can substantially reduce its transportation impact if workers are able to walk from the office to basic services. Transportation impact is the effect of transportation activities on the environment, society, and economy. Transportation impact can include greenhouse gas emissions, air pollution, noise pollution, energy consumption, land use, traffic congestion, infrastructure costs, and public health. Walking is a form of alternative transportation that can reduce transportation impact by using less energy, emitting less pollutants, occupying less space, and improving physical activity and well-being. If workers are able to walk from the office to basic services, such as retail, restaurants, banks, or post offices, they can reduce their vehicle miles traveled, fuel consumption, and parking demand1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Transportation and Climate Change
