         (2)   For paragraph 13 (2) (c) of the Act, the guidance in Schedule 1 is determined.

5              Advertisements

         (1)   For section 15 of the Act, an energy efficiency rating for a building must be expressed:

                (a)    by using a whole number, or one-half of a whole number, from 0 to 5, worked out for the building under the NABERS Energy rating rules as applied by section 6, with 0 indicating the lowest rating and 5 indicating the highest rating; and

               (b)    by adding the words ‘-star NABERS Energy rating’ after the number worked out under paragraph (a).

Examples

1   ‘4.5-star NABERS Energy rating’.

2   ‘3-star NABERS Energy rating’.

         (2)   The rating must be displayed prominently within an advertisement so that:

                (a)    it is clearly visible; and

               (b)    it is not obscured; and

                (c)    the number and the text included in the rating is at least as large as the majority of the text contained in the advertisement.

6              Methods and standards of assessment — energy ratings

         (1)   For paragraph 21 (1) (a) of the Act, the assessment methods and standards set out in this section and the NABERS Energy rating rules, as modified under subsection (2), are determined.

Purchase of alternative fuels not counted for ratings

         (2)   In the application of the NABERS Energy rating rules under subsection (1), the purchase of electricity under the GreenPower program is disregarded for the purpose of working out an energy efficiency rating for a building.

Note   Information about the GreenPower program is available at http://www.greenpower.gov.au.

Base building rating

         (3)   A person working out the energy efficiency rating for a building must work out the base building rating for the building.

         (4)   However, the person must work out the whole building rating for the building if it is not possible to work out the base building rating for the building because utility meters installed for the building are not sufficient to distinguish energy measured for a base building rating from energy measured for a tenancy rating.

Schedule 1        Energy efficiency guidance for building owners and tenants

(section 4)

   (e)  include in a user guide mentioned in paragraph (c), information about how daily tasks like opening and closing blinds and switching off lights can improve energy efficiency;

 

 

   (f)  seek regular tenant feedback on thermal comfort and lighting levels, and set up systems for responding to complaints;

 

 

   (g)  discuss with tenants the use of economical indoor temperature ranges, and recommend, for example, a temperature range of 20–22 °C in winter and 23–25 °C in summer;

 

 

   (h)  liaise with tenants about their hours of occupation, and realign HVAC operating times to reflect any changes to the hours of operation

4

improvements to lighting energy efficiency

   (a)  replace old lights with energy efficient ones, for example, with compact fluorescent lamps that use existing fittings;

   (b)  label light switches with clear descriptions of the associated lighting areas;

   (c)  install motion or noise sensors, and install switch‑off timers, for lights in areas that are not always occupied, for example, in storage areas;

   (d)  recommission lighting system controls to ensure they are working correctly;

   (e)  remove light fittings from over‑lit areas (after seeking advice about light levels and consulting with occupants)

5

opportunities for further energy saving improvements and upgrades

   (a)  check whether the temperature settings on domestic hot water systems can be reduced;

   (b)  ask tenants to trial using the recommended minimum settings for domestic hot water systems as follows:

         (i)   for storage systems — the minimum safe level is 60 °C;

        (ii)   for instantaneous systems — the minimum safe level is 50 °C;

   (c)  ask tenants to switch off hot water systems in areas where they are not essential;

   (d)  check whether hot water systems can be switched off overnight and on weekends;

 

 

   (e)  install programmable timers on instantaneous hot water systems;

   (f)  install flow control devices on hot water taps and showerheads and insulate hot water pipes and tanks where it is appropriate to do so;

   (g)  upgrade outdated electrical appliances and equipment with more energy efficient models;

   (h)  make sure that electrical equipment is operating on low energy mode or standby mode and is switched off when not in use;

 

 

    (i)  seek advice about upgrading the building envelope’s thermal performance, for example, advice about insulation, air seals and solar controls on glazing

6

on‑site management systems and processes

   (a)  install real‑time smart metering devices for sub‑metering major equipment and tenancies;

   (b)  monitor energy consumption in the building (for example, by making regular checks on bills, building management control system data, metering data and other relevant data), look for trends and diagnose areas of energy waste;

   (c)  keep management records up to date (for example, commissioning data, asset plans, complaints logs, and operations and maintenance manuals)

7

equipment settings, maintenance procedures and replacement schedules

   (a)  identify heating, ventilation and air conditioning (HVAC) equipment that is due for replacement and seek advice about energy efficient replacement options;

   (b)  check temperature sensor locations and move equipment (or sensors) if heating or cooling sources are interfering with HVAC settings;

   (c)  develop a preventative maintenance program and revise the operations and maintenance (O&M) manuals to reflect this;

   (d)  train the on‑site building manager to carry out simple HVAC maintenance tasks, and highlight the tasks and the building manager’s responsibilities in the O&M manuals;

   (e)  check that all preventative tasks relating to the maintenance of the HVAC system are included in the HVAC maintenance contract;

   (f)  aim for long‑term maintenance contracts, recognising that a longer term can enable contractors to better diagnose problems and identify areas for improvement;

   (g)  encourage maintenance contractors to provide feedback on energy waste, and ensure this feedback is acted upon

8

alternative fuels

   (a)  prioritise energy efficiency initiatives over the purchase of alternative fuels, recognising that the purchase of alternative fuels can reduce the building’s carbon emissions but will not reduce the building’s actual energy consumption;

   (b)  seek advice from suppliers about the suitability of purchasing alternative fuels

Part 2                     Guidance on how energy efficiency might be improved — tenants

Item

Guidance about ...

To improve the energy efficiency of an area of a building, a tenant can:

1

lease negotiations

   (a)  ask the building owner to include energy efficiency clauses in the lease contract (a green lease);

   (b)  use the negotiation period for the green lease to establish procedures for collaborating with the building owner on energy saving initiatives

2

improvements to lighting energy efficiency

   (a)  discuss the results of the tenancy lighting assessment (that building owners are required to arrange before entering a new lease) with the building owner to identify opportunities for improvement;

   (b)  replace old lights with energy efficient ones where they suit the existing fittings, and seek expert advice in the case of more complicated upgrades;

   (c)  label light switches with clear descriptions of the associated lighting areas;

   (d)  ask the building owner to adjust lighting controls so they suit the tenant’s requirements;

   (e)  look for opportunities to install automatic lighting controls, such as timers or sensors, for areas that are not always occupied

3

building management

   (c)  ask the lessor for an upgrade from normal tenant sub‑metering to real‑time or smart metering, and discuss the options and breakdowns for monitoring and reporting;

   (d)  ask the lessor for occupant‑controlled master isolation switches so the last person to leave the office can switch off lighting and appliances;

 

 

   (e)  ask the building manager to provide a building user guide that includes instructions about using blinds, windows and doors, being a guide that explains how tenants can make shading and natural ventilation work with the heating, ventilation and air conditioning system rather than against it;

   (f)  ask the building manager for advice about the optimum location of appliances, such as fridges, that generate heat;

 

 

   (g)  set up procedures for the prompt reporting of complaints and feedback about building services;

 

 

   (h)  ask the building manager to make seasonal adjustments to indoor temperatures that are within the range of
20–22 °C in winter and 23–25 °C in summer

4

energy efficiency policies and procedures

   (a)  develop and promote a corporate-wide energy management policy and action plan that includes targets, responsibilities and resources, and schedule regular progress reviews at senior management, executive or board meetings;

   (b)  check that all equipment and appliances are operating in low energy or standby mode;

   (c)  introduce a switch‑off policy that requires staff to switch off equipment when they leave the office or when the equipment is not in use;

   (b)  make the building user guide available to staff, and ensure it is covered by induction sessions for new staff;

 

 

   (c)  use information sessions, posters and signs to remind staff about saving energy and reducing the load on the air conditioning system;

   (d)  focus the awareness of staff on day‑to‑day activities that will improve comfort and allow building services to operate in the most energy efficient way, for example, activities such as:

         (i)   opening and closing blinds to make the most of natural light or to block unwanted heat;

        (ii)   switching off lights or hot water systems when they are not in use;

       (iii)   switching off supplementary air conditioning systems in vacant rooms;

       (iv)   using dishwashers only when they are full;

 

 

   (e)  make sure all staff members know how to use the building’s air conditioning system correctly;

   (f)  check with the building manager about the most efficient way of using building services after hours;

 

 

   (g)  make a note if staff attempt to alter or supplement the heating, ventilation and air conditioning system, for example, by blocking diffusers or by using personal heaters, and, in each case:

         (i)   asking the building manager for help in diagnosing the problem; and

        (ii)   ensure action is taken to resolve it;

   (h)  ask staff to use hot water efficiently and immediately report hot water leaks

6

alternative fuels

   (a)  prioritise energy efficiency initiatives over the purchase of alternative fuels, recognising that the purchase of alternative fuels can reduce the building’s carbon emissions but will not reduce the building’s actual energy consumption;
