Specification JV Annual Energy Consumption Criteria

Specification JV Annual Energy Consumption Criteria

1. Scope

This Specification contains the requirements for calculating the annual energy consumption of services in a building.

Intent

To clarify the requirements of the calculation for the annual energy consumption of services.

2. Annual energy consumption of services

The annual energy consumption—

(a)

for air-conditioning, must be calculated on the basis of—

(i)

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

(ii)

plant serving public areas of a Class 3 or 9c building being available on thermostatic control 24 hours per day; and

(iii)

the internal heat gains in a building—

(A)

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

(B)

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

(C)

from artificial lighting, that is calculated in (b); and

(b)

for artificial lighting, must be calculated on the basis of the proposed level of artificial lighting in the building with the daily profile in Tables 2a to 2g; and

(c)

for heated water supply, must be calculated on the basis of the consumption rates of Table 2i.

Application Internal heat gains per person
Dining room, restaurant or cafe
  1. 80 W sensible heat gain and 80 W latent heat gain
  2. The average adjusted metabolic rate for sedentary work from Table 45 of AIRAH-DA09
  3. The heat emission rate for sedentary work from Table 6.3 of CIBSE Guide A
Other applications
  1. 75 W sensible heat gain and 55 W latent heat gain
  2. An average adjusted metabolic rate from Table 45 of AIRAH-DA09

Notes:

  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 outline the inclusions in the method of calculation of annual energy consumption.

The Specification sets out a standard procedure for calculating annual energy consumption and provides various options in to account for heat gains per person and where applicable, heat gains from meals. The number of people must be calculated in accordance with .

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 .

They do not have to be used as part of the Verification Method provided the operating hours of the building per year used in the calculation are not less than 2,500 hours (see ).

to provide occupancy and equipment operation profiles for different building classifications and uses. Those for office buildings are the same as those used in the Australian Building Greenhouse Rating Scheme (ABGR) with respect to people and air-conditioning but not for lighting and office equipment. ABGR has higher values for equipment use.
