H6V2 Verification using reference building

When a model is created for a Specification 44 workflow, default internal loads, schedules and set points are required. We default to H6V2 Verification using reference building sections O-F for different space types.

Table H6V2a: Heating and Cooling Schedules

Table H6V2a outlines the hourly heating and cooling operation schedules for habitable rooms and bedrooms over a 24-hour period. It uses "ON" and "OFF" to indicate when heating or cooling is active, reflecting typical daily usage patterns based on occupancy and comfort needs.

0:00	OFF	ON
1:00	OFF	ON
2:00	OFF	ON

Here is Table H6V2b: Occupancy and Cooking Equipment Loads

Table H6V2b presents relationships between the floor area of habitable rooms, occupancy density, and cooking equipment loads. As floor area increases, the number of occupants per square metre decreases, and the cooking load per square metre of kitchen area also reduces, reflecting realistic diversity in usage.

Floor area of habitable rooms (m²)	Occupancy (m²/occupant)	Cooking equipment load (W/m² of kitchen area)
100	41.2	36.2
125	44.3	34.7
150	47.8	28.9
175	51.7	24.8
200	55.8	25.3
225	60.0	22.5
250	64.4	20.2
275	68.9	18.4
300	73.3	16.9
325	77.5	15.6
350	81.6	14.5
375	85.4	13.5
400	89.0	12.7

Table H6V2c Occupancy schedules

Table H6V2c defines hourly occupancy patterns for habitable rooms (separately for weekdays and weekends) and bedrooms (combined). The percentages represent the fraction of maximum occupancy, enabling accurate modelling of internal gains and system controls based on time-of-day presence.

Hour ending at	Weekday occupancy in habitable rooms other than bedrooms	Weekend occupancy in habitable rooms other than bedrooms	Weekday and weekend bedroom occupancy

Table H6V2d Lighting, cooking and appliance schedules

Table H6V2d provides the hourly usage profiles of lighting, cooking, and household appliances as percentages of their respective peak daily loads. These schedules are crucial for estimating internal heat gains and energy consumption in residential energy modelling.
