Specification JVc Modelling profiles

Specification JVc Modelling profiles

1. Scope

This Specification contains modelling profiles as referenced in subclause 3(c)(vii) of Specification JVb.

Intent

To prescribe the operation profiles that may be used in the modelling required by JV2 and JV3.

2. Modelling profiles

(a)

The air-conditioning, must be modelled on the basis of—

(i)

the daily occupancy and operation profiles in Tables 2a to 2k; and

(ii)

the internal heat gains in a building—

(A)

from occupants and hot meals, in accordance with one of the options in Table 2n; and

(B)

from appliances and equipment, in accordance with Table 2l; and

(C)

from artificial lighting, determined in accordance with (b).

(b)

The artificial lighting, must be modelled on the basis of the proposed level of artificial lighting in the building with the daily profile in Tables 2a to 2k.

(c)

The heated water supply, must be modelled on the basis of the consumption rates of Table 2m.

Table 2n Internal heat gains for occupants and hot meals

Application

Internal heat gains per person

Dining room, restaurant or cafe

(a) 80 W sensible heat gain and 80 W latent heat gain

(b) The average adjusted metabolic rate for sedentary work from Table 45 of AIRAH-DA09

(c) The heat emission rate for sedentary work from Table 6.3 of CIBSE Guide A

Other applications

(a) 75 W sensible heat gain and 55 W latent heat gain

(b) An average adjusted metabolic rate from Table 45 of AIRAH-DA09

(c) A heat emission rate from Table 6.3 of CIBSE Guide A

Note to Table 2n


Notes to Table 2n :

  1. The number of people must be calculated in accordance with D1.13.
  2. For a dining room, restaurant or cafe, the internal heat gains per person account for heat gains from both occupants and hot meals. For other applications, the internal heat gains per person only account for heat gains from occupants.
Intent

To prescribe the operation profiles for air-conditioning, artificial lighting, and equipment and appliances that may be used to model the proposed and reference building.

This Specification sets out standard operation profiles for calculating the annual energy consumption, and hence annual greenhouse gas emissions, of a proposed and reference building. It provides various options in Table 2n to account for heat gains per person and where applicable, heat gains from meals. The number of people must be calculated in accordance with D1.13.

Although the values stated may not be those actually achieved in some buildings, the values are derived from industry accepted data sources and are considered the most typical. The same rates apply for the proposed building and reference building under JV2 and JV3.

They do not have to be used as part of the Verification Methods provided the operating hours of the building per year used in the calculation are not less than 2,500 hours. The profiles in the NABERS Energy and Green Star simulation requirements can also be used (see subclause 3(c)(vii) of Specification JVb).
