Q1 · Difficulty 1/3
Which of the following BEST describes a 'green building'?
- A building painted green to reflect solar radiation
- A structure designed to minimise environmental impact throughout its lifecycle
- A structure located near a forest or natural green space
- A building constructed entirely from recycled steel and glass
Show answer & explanation
✓ Answer: B — A structure designed to minimise environmental impact throughout its lifecycle
A green building is one designed and operated to reduce negative environmental impacts and resource use across its entire lifecycle — from design and construction through to demolition. Option A confuses colour with sustainability. Option C is too narrow; green buildings use many strategies beyond recycled materials. Option D relates to location, not building design principles.
Q2 · Difficulty 1/3
Which certification system is most widely used internationally to rate and certify green buildings?
- ISO 14001
- ASHRAE 90.1
- LEED
- BREEAM
Show answer & explanation
✓ Answer: C — LEED
LEED (Leadership in Energy and Environmental Design), developed by the US Green Building Council, is the most widely recognised and internationally used green building rating system. ISO 14001 is an environmental management system standard for organisations, not specific to buildings. BREEAM is a UK-based rating system widely used in Europe but not as globally dominant as LEED. ASHRAE 90.1 is an energy efficiency standard, not a green building certification scheme.
Q3 · Difficulty 2/3
A homeowner in Barbados installs a photovoltaic (PV) panel system on a south-facing roof. What is the PRIMARY reason south-facing orientation is recommended in the Caribbean?
- South-facing roofs receive maximum solar radiation in the Northern Hemisphere
- South-facing roofs reduce the urban heat island effect more effectively
- South-facing roofs receive the most prevailing trade winds
- South-facing roofs are required by Caribbean building codes for all dwellings
Show answer & explanation
✓ Answer: A — South-facing roofs receive maximum solar radiation in the Northern Hemisphere
The Caribbean lies in the Northern Hemisphere, where the sun arcs across the southern sky; south-facing surfaces therefore receive the greatest annual solar irradiation, maximising PV output. Trade winds are not relevant to PV panel orientation. Reducing urban heat island effect relates to roofing materials and vegetation, not panel orientation. No universal Caribbean building code mandates south-facing panels specifically for all dwellings.
Q4 · Difficulty 2/3
In sustainable construction, which term refers to the total energy consumed by a building over its entire life, including construction, operation, and demolition?
- Embodied energy
- Passive energy
- Operational energy
- Lifecycle energy
Show answer & explanation
✓ Answer: D — Lifecycle energy
Lifecycle energy encompasses ALL energy used from raw material extraction through construction, occupancy, and eventual demolition. Embodied energy refers only to the energy used in producing and transporting materials. Operational energy covers only the energy used during the building's day-to-day use. Passive energy describes energy gained through passive design strategies, not a total energy measure.
Q5 · Difficulty 3/3
A building wall assembly has the following R-values for each layer: outer render = 0.04 m²K/W, concrete block = 0.19 m²K/W, insulation = 1.80 m²K/W, inner plaster = 0.03 m²K/W. What is the total thermal resistance (R-value) of the wall assembly?
- 2.06 m²K/W
- 1.84 m²K/W
- 1.99 m²K/W
- 2.10 m²K/W
Show answer & explanation
✓ Answer: A — 2.06 m²K/W
Total R-value = sum of all individual layer R-values. R_total = 0.04 + 0.19 + 1.80 + 0.03 = 2.06 m²K/W. Option A (1.84) omits the concrete block layer. Option C (1.99) omits the outer render. Option D (2.10) adds an incorrect value, possibly by rounding one layer up. The formula is R_total = R₁ + R₂ + R₃ + R₄ for layers in series.
Q6 · Difficulty 3/3
A community centre in Jamaica uses a 5 kW solar PV system that generates electricity for an average of 6 hours per day. The building's daily electricity consumption is 25 kWh. Evaluate whether the PV system meets the building's daily energy demand and identify the energy surplus or deficit.
- The system generates 20 kWh/day — a deficit of 5 kWh/day
- The system generates 30 kWh/day — a surplus of 5 kWh/day
- The system generates 30 kWh/day — a deficit of 5 kWh/day
- The system generates 25 kWh/day — exactly meeting demand with no surplus
Show answer & explanation
✓ Answer: B — The system generates 30 kWh/day — a surplus of 5 kWh/day
Energy generated = Power (kW) × Time (hours) = 5 kW × 6 h = 30 kWh/day. Daily demand = 25 kWh. Surplus = 30 − 25 = 5 kWh/day. The system exceeds demand by 5 kWh. Option B incorrectly states output equals demand (confusing 5 kW × 5 h = 25 kWh). Option C uses 4 h instead of 6 h (5 × 4 = 20). Option D correctly calculates 30 kWh but then incorrectly states it as a deficit.
CXC CSEC Building Technology FAQ
What does the CXC CSEC Building Technology exam look like?
The CXC CSEC Building Technology exam is structured across 3 components. Paper 1 (Section A): 60 multiple-choice questions, 1 mark each. 75 minutes. Tests knowledge across the whole syllabus. Paper 2: Structured short-answer + 1 extended response question. Section A is compulsory; Section B has a choice. Approximately 2 hours 10 minutes. School-Based Assessment (SBA): Coursework component graded by the teacher, externally moderated. Worth ~20-30% of the final grade depending on subject. Total exam time: ~3.5 hours across Paper 1 and Paper 2 sittings.
Can I download a free CXC CSEC Building Technology past paper?
Real CXC past papers are published directly by CXC on their official website. Kramizo doesn't redistribute copyrighted past papers, but we do generate free AI-written practice papers in the exact same style — same command words, same difficulty tier, same mark conventions. Use this practice paper as warm-up, then time yourself on official past papers before exam day.
How is CXC CSEC Building Technology graded?
Grades: I (highest) to VI (lowest). A grade of III or above is typically required for further study. Kramizo's practice questions are tagged with difficulty 1-3 mapping roughly to the lower, middle, and top grade boundaries you'll encounter in the real exam.
