the premises are part only of the tenancy building; and

(b)

the landlord is not the sole owner of the whole of the tenancy building; and

(c)

complying with regulation 6 (in the absence of this regulation) would require—

(i)

something to be installed or provided in part of the building of which the landlord is not the sole owner; or

(ii)

the landlord (or a person acting on the landlord’s behalf) to access part of the building of which the landlord is not the sole owner; and

(d)

the matters referred to in paragraphs (a) to (c) impede the landlord’s ability to comply with regulation 6.

(3)

Regulation 6(2) applies as if—

(a)

“take all reasonable steps to” were inserted before “ensure” in each place; and

(b)

the following paragraph were inserted after paragraph (b):

“(ba)

if, despite paragraphs (a) and (b) being complied with, the premises or tenancy building does not meet a standard set out in any of subparts 2 to 6, take all reasonable steps to ensure that it meets that standard to the greatest extent reasonably practicable; and”.

Example

Mr L is the landlord of premises that are part of a unit title development. The required heating capacity for the main living room of the premises is 3 kW. The only reasonably practicable qualifying heater Mr L could install would be a fixed heat pump. However, the body corporate’s rules prohibit the installation of external heating units on common property without the consent of the body corporate.

Regulation 6(2)(a), as modified by this regulation, would require Mr L to take all reasonable steps to get consent from the body corporate to install the heat pump.

If Mr L were not able to get consent, paragraph (ba) would require him to comply with the heating standard to the greatest extent reasonably practicable, for example, by installing a different kind of qualifying heater that does not require an external unit, even if its heating capacity is less than the required 3 kW.

For the purpose of determining its area or construction R-value, a window, skylight, or door is taken to include its frame and associated joinery.

2 Required heating capacity

is the transmission heat loss in respect of the building elements that form the boundaries of the living room but are not part of the building’s thermal envelope (W)

Aq

is the area of ceiling q (m2)

Rq

is the construction R-value of ceiling q (°Cm2/W)

q

is the numbering index for all of the living room’s ceilings that are part of the boundary of the living room but are not part of the building’s thermal envelope

As

is the area of wall s (m2)

Rs

is the construction R-value of wall s (°Cm2/W)

s

is the numbering index for all the living room’s walls that are part of the boundary of the living room but are not part of the building’s thermal envelope

Au

is the area of floor area u (m2)

Ru

is the construction R-value of floor area u (°Cm2/W)

u

is the numbering index for all of the living room’s floors that are part of the boundary of the living room but are not part of the building’s thermal envelope.

(4)

For the purposes of subclauses (2) and (3), if a ceiling, wall, or floor consists of 2 or more areas that have different construction R-values, each of those areas is taken to be a separate ceiling, wall, or floor.

4 Ventilation heat loss

The ventilation heat loss of a living room is to be calculated using the following formula:

v = w × y × z × (b − c)

where—

v

is the ventilation heat loss of the living room (W)

w

is the internal volume of the living room (m3)

y

is the assumed air change rate of the living room, being 1.0

z

is the assumed value for the density of air multiplied by the specific heat of air, being 0.34 Wh/m3K

b

is the required internal temperature, being 18°C

c

is the assumed external temperature for the premises as set out in clause 5.

5 Assumed external temperature

The assumed external temperature for residential premises is the temperature set out in the following table for the territorial authority in whose district the premises are located.
