1. Which document provides the primary guidance for the conservation of fuel and power in
new and existing buildings in England?
A. Approved Document L
B. Approved Document P
C. Approved Document G
D. Approved Document F
Answer: A
Conceptual Explanation: Approved Document L deals with the conservation of fuel and
power, setting standards for energy efficiency in buildings.
2. What is the primary role of the Microgeneration Certification Scheme (MCS)?
A. To provide insurance for installers
B. To issue building control certificates for all electrical work
C. To ensure quality of products and installations for eligibility in incentive schemes
,D. To define the health and safety regulations for construction sites
Answer: C
Conceptual Explanation: MCS is a quality assurance scheme that certifies
microgeneration technologies and installers to ensure standards are met, often required
for financial incentives.
3. Under Permitted Development rights, which of the following is usually a restriction for
building-mounted Solar PV?
A. It must not exceed a total area of 2 square meters
B. It must be installed on the north-facing roof only
C. It must be colored to match the existing roof tiles
D. It must not protrude more than 200mm from the wall or roof slope
Answer: D
Conceptual Explanation: Permitted development rules for England state that panels
should not protrude more than 200mm beyond the plane of the wall or roof slope.
4. What is the ‘Coefficient of Performance’ (COP) used to measure in a Heat Pump system?
A. The ratio of heat output to electrical energy input
B. The speed of the circulating pump
C. The maximum temperature the pump can achieve
D. The volume of refrigerant within the system
, Answer: A
Conceptual Explanation: COP is the ratio of useful heat provided by the heat pump to the
electrical energy consumed to move that heat.
5. Which Solar Thermal collector type is generally more efficient in colder, windier conditions
due to reduced convective heat loss?
A. Evacuated tube collector
B. Unglazed plastic collector
C. Flat plate collector
D. Parabolic trough
Answer: A
Conceptual Explanation: Evacuated tubes have a vacuum between the glass layers, which
acts as excellent insulation, minimizing heat loss to the outside air.
6. In a Solar PV system, what is the function of the ‘Inverter’?
A. To step up the AC voltage to 400V
B. To store energy for use during the night
C. To convert DC generated by the panels into AC for use in the building
D. To track the sun’s position throughout the day
Answer: C
