PQP-RE Flashcards
What are the 3 techniques or methods that RE emphasize to reduce energy demand?
- Passive environmental design 2. Appropriate selection of highly efficient mechanical and electrical equipment 3. Facilitation of renewable energy installation.
What are the general credit requirement for RE-R1?
- Energy model, 2. Minimum 12% performance improvement vs baseline performance
The proposed building performance and baseline building performance shall include which end- use load components?
Lighting, Heating, Cooling, Heat Rejection, Pumps, Fans, Service water heating and Receptacle and process loads.
For Emirates of Abu Dhabi what is assumed condition for weather data?
Climate zone 1b “Very Hot and Dry”
How should receptacle and process loads be modelled?
It should be identical in both baseline and proposed building.
Examples of receptacle and process loads
Office equipment, computers, elevators and escalators, kitchen equipment, laundry equipment, water treatment
What is the seasonal average COP if sufficient data cannot be provided on DC network?
COP=4.5
How do renewable energy help in achieving RE-R1?
Renewable energy may be subtracted from the proposed building energy consumption including where the energy produced is exported to the electrical grid.
What is the primary intention of RE-R2?
Improve and understand the use of energy in the buildings by using metering facilities for recording and monitoring of energy performance.
What is required of energy sub-meters?
- Easily accessible; 2. Clearly labelled; 3. Capable of monitoring energy consumption
True or False: All onsite energy generating systems must be seperately metered and their annual energy generation recorded.
TRUE
Can an ODP >0 achieve RE-R3 credit?
No. ODP should be zero.
True or False: RE-R3 refers only to the the refrigeration system contained within the site boundary.
True. District cooling systems which will provide only chilled water to the site are not subject to the requirement of RE-R3.
A document that should be submitted for both RE-R1 and RE-1 credits.
Energy Model Template
1 credit point for RE-2 is awarded for roofing materials with what value of SRI?
SRI>/= 78
Considerations to implement passive design measures?
Building orientation, fixed shading devices, improvements to building fabric, air tightness
What are passive design measures to achieve RE-2?
Cooling methods which require no mechanical systems.
Defined as the sum of solar gain, external conduction gain and infiltration gain.
External heat gain
The ratio of the total area of glazing on a façade to the total façade area.
Glazing Ratio
How are roof areas covered by external shading devices calculated?
As portion of roof area in shade measured at 12 pm solar time on the summer solstice.
In what instance do RE-3 awarded automatically?
When building contains no roof (excluding areas with mechanical plant, vegetated roof and with renewable technologies).
A document that is needed to achieve RE-3 requirements.
Proof of certification by Energy Star program, EU Energy Efficiency Labeling Scheme or equivalent.
What are the equipment considered in RE-4?
Stairs, Lifts, Escalators/Travelators
What is the CRI value required for lighting used within the stairs?
CRI 80
