Energy and Atmosphere promotes the following measures… (4)
|
• Energy reduction and efficiency
• Using benign forms of energy • Ensuring continued energy performance • Managing refrigerants |
|
|
The goals of Energy and Atmosphere can be achieved by implementing the following strategies: (5)
|
• Reducing energy demand
• Increasing energy efficiency • Renewable energy • Commissioning, Monitoring & verification • Refrigerant management to eliminate CFCs |
|
|
EPA’s ENERGY STAR Target Finder is ...
|
An online tool that allows planners to set an aggressive energy performance target for building design and compare estimated energy consumption to the established target.
|
|
|
Energy efficiency strategies are: (3)
|
• Passive and thermal design.
• High performance building envelope and building systems. • Verify and monitor building performance. |
|
|
Process energy is considered to include, but is not limited to...
|
Office and general miscellaneous equipment, computers, elevators and escalators, kitchen cooking and refrigeration, laundry washing and drying, lighting exempt from the lighting power allowance (e.g., lighting integral to medical equipment) and other (e.g., waterfall pumps).
|
|
|
Regulated (non-process) energy includes …
|
Lighting (for the interior, parking garage, surface parking, façade, or building grounds, etc. except as noted above), heating, ventilation and air conditioning (HVAC) (for space heating, space cooling, fans, pumps, toilet exhaust, parking garage ventilation, kitchen hood exhaust, etc.), and service water heating for domestic or space heating purposes.
|
|
|
Renewable energy sources include: (7)
|
• Photovoltaic
• Wind energy • Solar thermal: active and passive • Biofuels: from organic materials such as wood by-products and agricultural waste • Geothermal heating • Low impact hydroelectric • Wave and tidal |
|
|
Green-e is...
|
A certification program for renewable energy that has been certified by the Center for Resource Solutions.
|
|
|
There are 3 approaches to purchase offsite renewable energy:
|
• Open electricity market: governing utility company may be able to select a Green-e certified provider
• Closed electricity market: governing utility company may be a Green-e certified provider • If local utility company cannot provide Green-e certified power, Owner may purchase renewable energy certificates (RECs) |
|
|
RECs are also known as...
|
Green tags, Renewable Electricity Certificates, or Tradable Renewable Certificates (TRCs).
|
|
|
RECs are ...
|
Tradable, non-tangible energy commodities in the United States that represent proof that 1 megawatt-hour (MWh) of electricity was generated from an eligible renewable energy resource (renewable electricity)
|
|
|
Purchase offsite renewable energy is based on… and must be at least a…
|
• Based on quantity of energy consumption, not energy costs.
• Must be at least a 2 year contract for 35% of the building’s electricity consumption. |
|
|
Commissioning (Cx) is ...
|
a mandated quality control process that should be initiated at the beginning of the project.
|
|
|
The benefits of commissioning include ... (5)
|
• Reduced energy use, lower operating costs,
• Fewer contractor callbacks, • Better building documentation, • Improved occupant productivity and • Verification that the commissioned systems perform in accordance with the owner’s project requirements. |
|
|
At a minimum, the systems to be commissioned are: (4)
|
• HVAC&R systems and related controls
• Lighting and daylighting controls • Domestic hot water systems • Renewable energy systems |
|
|
In the prerequisite EAp1, the commissioning steps include: (7)
|
• Designate the commissioning authority (CxA)
• Document owners project requirements (OPR) and develop the basis of design (BOD) • Review OPR and BOD • Develop and implement a commissioning plan • Incorporate commissioning requirements into the construction documents • Verify installation and performance of commissioned systems • Complete a summary commissioning report |
|
|
EAc3 Enhanced Commissioning: Enhanced commissioning requires the CxA to be on the project earlier and stay on the project later than what is necessary with Fundamental Commissioning by requiring 3 additional tasks to be added to the scope. The 5 tasks, in order, are:
|
• Conduct commissioning design review prior to mid-construction documents
• Review contractor submittals applicable to systems being commissioned • Develop systems manual for commissioned systems • Verify that requirements for training are completed • Review building operation within 10 months after substantial completion |
|
|
Monitoring and verification tracks …
|
Energy performance by comparing actual building performance measurements against predictions from energy simulations or industry standard benchmarks.
|
|
|
EPA’s Energy Star Portfolio Manager is...
|
A project database of electricity and natural gas consumption to compare against a benchmark building to arrive at a building’s energy performance.
|
|
|
Features of CFC (ChloroFluorCarbons):
|
• Stability and long life with greatest Ozone Depletion Potential (ODP) caused the production to be banned in 1995.
|
|
|
Features of HCFC (HydoChloroFluorCarbons):
|
• Stable and short life, not as great ODP as CFCs, allowing a phase out plan.
|
|
|
Halocarbons
|
• Used in the cells of foamed insulation and fire fighting systems
|
|
|
Natural Refrigerants include... (4)
|
• Carbon Dioxide (CO2)
• Water (H2O) • Ammonia (NH3) • Hydrocarbons (HC) |
|
|
Home Energy Saver is ...
|
A government program used for performing energy audits on residential projects.
|
|
|
The main standard that establishes minimum requirements for the energy efficient design of buildings is...
|
ASHRAE Standard 90.1-2007
|
|
|
The main standard that establishes minimum requirements for the ventilation of buildings is...
|
ASHRAE Standard 62.1-2007
|
|
|
Simple Payback Method is...
|
Payback considers the initial investment costs and the resulting annual cash flow. The Simple Payback Method calculates the amount of time (usually measured in years) to recover the initial investment in an opportunity.
|
|
|
The Montreal Protocol is...
|
