Environmental-Awareness Test 1

According to UK Building Regulations Part L, what must the designed carbon emission rate (DER) and Building Emission Rate (BER) not exceed?

• The average national emission rate

• The Target Emission Rate (TER) for a similar building

• The maximum U-Value for external walls

• The Building Services Efficiency Standard

Which Approved Document covers conservation of fuel and power in existing dwellings?

• Approved Document L1A

• Approved Document L1B

• Approved Document L2A

• Approved Document L2B

Part F defines ventilation as which process?

• Sealing buildings to prevent air leakage

• Removing 'stale' air and bringing in 'fresh' air from outside

• Increasing internal humidity to reduce heat loss

• Filtering internal air without exchanging it with outside air

What is a benefit of removing stale air under Part F?

• Increased solar gains

• Greater airtightness without heat loss

• Removal of airborne odours, pollutants and bacteria

• Higher U-Values in building fabric

The Domestic Building Services Compliance Guide 2013 (with 2018 amendments) gives guidance for which part of the Building Regulations?

• Part F: Ventilation

• Part L: Conservation of Fuel and Power

• Part J: Combustion Appliances

• Part P: Electrical Safety

Which section in the Domestic Building Services Compliance Guide is based on technology, not fuel?

• Section 4 Electric heating

• Section 5 Solid fuel heating

• Section 8 Mechanical ventilation

• Section 2 Gas-fired space and water heating

Which UK framework is used to show compliance with Building Regulations Part L for energy performance in homes?

• Domestic Building Services Compliance Guide

• Standard Assessment Procedure (SAP)

• Reduced Standard Assessment Procedure (RdSAP)

• Central Heating System Specifications (CHeSS)

Which statement best describes a regular boiler in domestic central heating systems?

• It provides hot water directly and may have an internal store.

• It heats a thermal store using a burner.

• It does not provide hot water directly and usually uses a separate hot water store.

• It is always non-condensing and cannot be used with compliant systems.

Which SEDBUK band is for boilers with 82%–86% efficiency?

• Band A

• Band B

• Band C

• Band D

For a basic vented hot water cylinder, what is the required maximum standing heat loss per 24 hours? Use V for cylinder capacity in litres.

• Standing heat loss ≤ (0.2 + 0.051 × V) kWh/24h.
