Building-Level Energy Monitoring
Fundamental Refrigerant Management
What are the Benefits of utilizing a CxA?
Minimize or eliminate design flaws.
Avoid construction defects.
Avoid equipment malfunctions.
Ensure preventative maintenance is implemented during operations.
HVAC&R
Heating, ventilation, air conditioning, and refrigeration
What is the baseline standard for energy performance?
ASHRAE 90.1-2010, Appendix G
Passive designs capitalize on the four natural thermal processes»>
Radiation
Conduction
Absorption
Convection
What are the uses for regulated energy?
Lighting: interior and exterior applications (parking garages, facades, site lighting)
HVAC: space heating, cooling, fans, pumps, toilet exhaust, ventilation for parking garages
Domestic and space heating for service water
What are the uses for process energy?
Computers, office equipment, kitchen refrigeration and cooking, washing and drying machines, and elevators and escalators. Miscellaneous items, such as a waterfall pump, and lighting that is exempt from lighting power allowance calculations such as lighting integrated into equipment, are also categorized as process energy uses.
What two components should be evaluated when determining which refrigerants to use?
Refrigerants should be evaluated based on ODP and GWP impacts.
ODP
Ozone-Depleting potential
GWP
Global warming potential
What is the requirement for existing building projects that have CFC refrigerants?
The CFCs must be phased out
What are the four components of the Energy & Atmosphere category?
Energy demand
Energy efficiency
Renewable energy
Ongoing energy performance
How are electricity, natural gas, and liquid fuel each measured?
electricity is measured in kilowatts per hour
natural gas in therms
liquid fuel in gallons
What are the four strategies to reduce energy demand?
Establish design and energy goals.
Size the building appropriately.
Use free energy.
Insulate.
What are the six strategies to use energy more efficiently?
Address the envelope. Install high-performance mechanical systems and appliances. Use high-efficient infrastructure. Capture efficiencies of scale. Use energy simulation. Monitor and verify performance.
What are the six types of eligible renewable energy sources for LEED projects?
Solar, wind, wave, biomass, geothermal power, and low-impact hydro-power
What are the two ways to incorporate renewable energy into a green building project?
Generate on-site renewable energy and/or purchase green power or RECs.
REC
Renewable energy credit
What are the four strategies to ensure optimal performance for a LEED project?
Adhere to the OPR.
Provide staff training.
Conduct preventative maintenance.
Create incentives for occupants and tenants.
What are the three components to address within the Materials & Resources category?
The conservation of materials
Environmentally, socially and locally preferable materials
Waste management and reduction
What is a rapidly renewable material?
Fiber or animal materials that must be grown or raised in 10 years or less.
Define recycled content
The percentage of materials in a product that are re-cycled from the manufacturing waste stream (preconsumer waste) or the consumer waste stream (postconsumer waste) and used to make new materials. recycled content is typically expressed as a percentage of the total material volume or weight.
What referenced standard declares a material having postconsumer/preconsumer recycled content?
ISO 14021-1999 - Environmental Label and Declarations
