Energy Conservation – MCQ from Study Material (Basic Level)

Section 5.2.4 explicitly states that the sealing requirements apply to all except naturally ventilated buildings or spaces, which rely on air movement through openings.

Table A2.1 lists New Delhi under the 'Composite' climate zone, which is characterized by a combination of hot-dry, warm-humid, and cold seasons.

Table A1.1 in the appendix assigns a default U-factor of 5.1 for metal frames without a thermal break and double glazing.

The document explicitly expands the acronym to ‘LIFE’– ‘Lifestyle for Environment’, promoting a mass movement based on conservation and moderation.

The updated NDC commits to achieving about 50 percent cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030.

Section 8.2.11 specifies that lifts in Super ECSBC buildings must achieve an energy classification of 'A' as defined in IS 17515 – Part 2.

Section 10.3.2 requires that for Super ECSBC compliance, 95% of organic waste generated post-occupancy is composted on-site.

The definition for Gray Water includes wastewater from bathtubs, showers, and lavatories, excluding toilet and kitchen sink waste.

Section 8.2.2 specifies that the voltage drop for any branch circuit shall be a maximum of 3% at design load.

Section 8.2.1 specifies that an ECSBC Plus building requires transformers conforming to the BEE 4-star labelling requirement.

The copyright and publisher information on the title page clearly identify the Bureau of Energy Efficiency as the publisher.

Section 2.5 states if a part of the building has a different classification and is less than 10% of the area, it can be treated as part of the primary classification.

Section 4.2.4 requires that the clear width of the accessible entrance door shall not be less than 900mm.

Section 2.2 states that the provisions of the code do not apply to plug loads, which are devices plugged into outlets by occupants.

Section 5.2.3 mandates that a certain percentage of the floor area must meet the UDI requirements, which measures the annual hours a space receives usable daylight.

The U-factor, or thermal transmittance, measures heat transmission per unit area per unit temperature difference. A lower U-factor means better insulation.

Section 6.2.3-(b) requires that controls shall be capable of providing a temperature dead band of 3.0°C within which energy supply is shut off.

The definition states a cool roof has high solar reflectance to reject sunlight and high thermal emittance to radiate away absorbed heat.

The definition for 'Fenestration' explicitly categorizes a surface with a slope less than 60 degrees from the horizontal as a skylight.

The document explicitly states that the update to the NDC is a step towards the long-term goal of reaching net-zero by 2070.

The updated NDC states a commitment to reduce the emissions intensity of its GDP by 45 percent by 2030 from the 2005 level.

Section 10.3.1 specifies that for ECSBC Plus compliance, 75% of non-hazardous waste must be reused, repurposed, recycled, or salvaged.

Table 9.1 specifies that domestic water pumps, flushing water pumps, and surface water pumps must have a minimum overall efficiency of 60%.

Section 8.2.11-(e) mandates that a minimum of 20% of the parking capacity must have EV charging facilities for baseline ECSBC compliance.

Section 8.2.3 specifies that ECSBC Compliant buildings must use motors of the minimum IE 3 (high efficiency) class.

Table 7.1 lists the Lighting Power Density for an Office Building at the ECSBC compliant level as 9.5 W/m2.

Section 5.3.3 states that the maximum allowable Window Wall Ratio (WWR) is 40% for buildings using this compliance method.

Section 5.3.3 states that the maximum allowable Window Wall Ratio (WWR) is 40% for buildings using this compliance method.

Section 4.2.1 specifies that fertile topsoil ranging from 150 to 200 mm in depth must be preserved and stabilized.

The code outlines these two paths: ICM, which uses whole-building simulation, and SCM, which follows a prescriptive approach.

This category is explicitly defined to include schools, colleges, universities, and other training institutions used for instruction and education.

The code establishes a baseline 'ECSBC Compliant' level that is mandatory, while the higher tiers (Plus and Super) are voluntary and aspirational.
