Which factor most directly affects the rate of heat gain and loss in a home?
Number of light fixtures
Length of driveway
Roof color
Insulation R-value of walls and ceiling
The R-value of insulation measures its thermal resistance, directly influencing heat gain and loss. Better insulation reduces energy consumption for heating and cooling by slowing temperature transfer.
Which device is designed to eliminate standby power consumption from electronics?
Programmable thermostat
Solar charger
LED light bulb
Smart power strip
A smart power strip cuts power to devices when they are not in active use, preventing standby or phantom loads. Other options do not directly control standby power.
What does the term "R-value" measure in home construction?
Thermal resistance of insulation
Reflectivity of windows
Solar panel output
HVAC system efficiency
R-value quantifies how well insulation resists heat flow, with higher values indicating better insulating performance. It does not apply to windows or HVAC ratings.
Which type of light bulb is most energy-efficient for household lighting?
LED bulb
Incandescent bulb
Halogen bulb
CFL bulb
LED bulbs convert a higher percentage of electricity into light and have longer lifespans than incandescent, halogen, or CFL options. This makes them the most energy-efficient choice.
Reducing the thermostat setpoint by 1°F during heating season typically reduces energy use by about what percentage?
0.2%
1%
5%
10%
Industry studies show that lowering the thermostat by 1°F can reduce heating energy consumption by roughly 1%. Larger setpoint reductions yield proportionally greater savings.
In winter, which part of a home typically accounts for the greatest heat loss?
Doors
Interior walls
Floor
Roof and attic
Heat rises, making the roof and attic area the largest source of heat loss without proper insulation. Floors and interior walls lose much less by comparison.
What does the SEER rating on an air conditioning unit represent?
Standard Energy Usage Rate
Seasonal Energy Efficiency Ratio for cooling
System Emission Efficiency Rating
Seasonal Electrical Utilization Ratio
SEER measures the cooling output over a season divided by energy consumed, indicating an air conditioner's efficiency. It is not related to emissions or general usage rates.
If replacing old bulbs costs $200 and saves $50 per year on your energy bill, what is the simple payback period?
1 year
4 years
2 years
8 years
The simple payback period equals initial cost divided by annual savings: $200 ÷ $50/year = 4 years. This measures how long it takes to recoup the investment.
Which action most effectively reduces energy loss in a forced-air duct system?
Extending duct length
Painting ducts white
Routing ducts through interior walls
Sealing duct leaks
Sealing leaks prevents conditioned air from escaping and unconditioned air from entering, improving system efficiency. Painting or lengthening ducts has negligible impact on loss.
Which option is an example of integrating renewable energy in a residential setting?
Increasing attic insulation
Installing a standby generator
Installing rooftop solar panels
Using a smart thermostat
Rooftop solar panels generate electricity from a renewable source, directly integrating renewables into home energy. Other options address efficiency or backup power, not renewable integration.
What does net metering allow solar PV owners to do?
Avoid all grid connection fees
Sell excess electricity back to the grid
Store excess energy in site battery only
Increase panel efficiency
Net metering credits solar owners for surplus power sent to the grid, offsetting future bills. It does not directly improve efficiency or eliminate fees.
Which window feature most improves thermal performance?
Single-pane glass
Aluminum frame
Low-emissivity (Low-E) coating
Clear tempered glass
Low-E coatings reflect heat back toward its source, reducing heat loss in winter and heat gain in summer. Single-pane or metal frames offer much less insulation.
Which roof color choice helps reduce cooling loads in hot climates?
Light reflective or white roof
Standard metal roof
Dark asphalt shingles
Green tinted shingles
Light reflective or white roofs reflect more solar radiation, lowering attic temperatures and cutting cooling demands. Dark roofs absorb heat and increase indoor temperatures.
What test is used to measure a home's air infiltration rate directly?
Blower door test
Smoke pencil test
Watt meter reading
Infrared thermal imaging
A blower door test pressurizes or depressurizes the home to quantify air leaks precisely. Infrared cameras identify drafts visually but don't measure infiltration rate numerically.
Which factor most influences the efficiency of a ground-source (geothermal) heat pump?
Orientation of windows
Length and depth of the ground loop
Age of the home
Color of outdoor unit
The ground loop length and depth determine the thermal exchange capacity with the earth, directly impacting system efficiency. Other factors are secondary for the loop's performance.
How should a homeowner use energy storage under a time-of-use rate structure to minimize electricity costs?
Charge battery continuously regardless of time
Never use battery to avoid cycling losses
Charge battery during peak and discharge during peak
Charge battery during off-peak and discharge during peak
Time-of-use rates charge lower prices off-peak, so storing energy then and discharging at peak rates reduces overall electricity costs. Charging at peak would incur higher rates.
Which combination of features is most likely to achieve net-zero energy performance?
High insulation, passive solar design, solar PV, and battery storage
Standard insulation, gas furnace, grid-tied PV only
High insulation, reflective roof, no renewables
Light insulation, small PV array, standby generator
A net-zero home balances demand reduction through high insulation and passive design with renewable generation and storage. Merely adding PV or insulation alone is insufficient.
Thermal bridging occurs when structural elements conduct heat across insulation. Which mechanism best describes this effect?
Direct conduction through studs bypassing insulation
Infrared radiation through air gaps
Absorption of moisture in drywall
Convection currents within wall cavities
Thermal bridging is the conduction path provided by studs or framing, which bypasses the insulation's thermal resistance. Radiation and convection play lesser roles in this phenomenon.
If a solar PV system costs $10,000, receives $3,000 in incentives, and saves $800 annually on electricity bills, what is its simple payback period?
5 years
7 years
10 years
8.75 years
Subtract incentives from cost then divide by annual savings: ($10,000−$3,000) ÷ $800/year = 8.75 years. This calculates how long until the net investment is recovered.
In PV systems, what is the effect of inverter clipping on annual energy yield?
Boosts feed-in tariff rates
Eliminates mismatch losses between panels
Increases energy output under low light
Reduces energy output when DC power exceeds inverter capacity
Inverter clipping occurs when the solar array produces more DC power than the inverter can convert to AC, causing excess generation to be curtailed. It does not affect tariffs or improve low-light performance.
