B4.9 ENERGY CONSERVATION & MANAGEMENT B4.9.1 Preamble The University recognises energy conservation and management as a significant element of life cycle costing of new and existing buildings. It is important that an efficient use of energy is accomplished through effective building design. Accordingly, all factors influencing energy consumption shall be considered throughout the design stage. B4.9.2 General Principles and Guidelines When considering use and occupation of buildings, it is desirable that the interface between different user groups, activities and zones within buildings be limited. Where feasible, areas with expected similar energy requirements are to be grouped together. Where multiple unrelated users occupy buildings, the University requires that energy consumption of each group shall be individually monitored. To optimise internal environmental conditions, the following shall be considered: - mechanical ventilation to comply with AS1668. Consider all natural ventilation possibilities; - generally, the University is committed to air-conditioning the buildings to provide a safe and comfortable work environment. However, other energy efficient systems that satisfy the above goals shall be considered if able to meet the University’s OH & S Guidelines for human comfort; - humidity control shall only be provided for specific experimental or storage purposes; - task lighting shall be used wherever practical rather than overall illumination techniques that may require an unnecessarily high level of illumination; - building automation systems (BAS) as described in Section B4.7 'Monitoring and Controls', are used in all University buildings which allows: 1 operation of building plant to be monitored and controlled in each building; 2 plant operation viewing from a central control station and any adjustment of control systems implemented from there;
3 alarm messages transmission to the central control station when the BAS detects a malfunction. The system stores historical data on the PC located in the central control station for diagnostic, energy billing and design purposes; - new plant/controls installed in existing/new buildings shall be suitable for connection to the BAS; - electricity and gas tariffs have been negotiated by the University with the local supply authorities. Consultants should check with the Division’s technical staff when preparing energy consumption or life cycle costing analyses. B4.9.3 Environmental and Architectural Considerations Building form shall be in accordance with the principles outlined in Sections B1 and B3. Organise the efficient use of circulation space and zoning to minimise overall building volume(s). The effects of shape, mass and orientation shall be considered in developing a thermally efficient building design. Roof spaces and walls of buildings shall have adequate thermal resistance to heat loss/gain. The design and position of glazed fenestrations shall ensure that the need for natural light and ventilation is weighed against solar and thermal loads. Demonstrate adequate consideration of the following: - sun control techniques (including sun shades and glare control); - maximum use of natural light and ventilation; and
Internal or glass applied films and sun control measures, shall not be used unless external measures cannot be applied. Internal wall finishes shall be in accordance with the recommendations outlined in AS1680.1 (Section 6) regarding the reflectance of surfaces. Task areas shall be protected from all sources of glare with particular attention being given to areas where personal computers are to be located. B4.9.4 Mechanical Services and Equipment Energy targets shall be established for new buildings to provide a measure of energy efficiency for the design and the impact of any special requirements outlined in the project brief. Such targets will then be used to assess the achievement of energy efficiency in subsequent operation.
When determining the size of plant to be installed, consideration must be given to: - using double glazing for windows to reduce thermal loads on the building; - the availability of power; - the provision of modular plant for flexibility in meeting seasonal changes and changing use patterns; and - thermal storage and heat recovery systems. Ventilation fan power consumption shall be minimised by: - designing ducting and equipment for low static resistance to ensure low fan pressure; - using variable air flow volume to reduce fan power at part load; - selecting the fan and drive train for high efficiency; and - using efficient means to vary fan performance to suit variable air volume (VAV) system. Pumps shall be specified to: - operate at the highest efficiency point avoiding the use of undersized piping systems; and - include consideration of sequenced steps or modulations of pumping capacity for economy. Evaporative cooling is energy efficient when large quantities of air are cooled and the relative humidity is low. Systems integrating both evaporative cooling and heating are not generally energy efficient and incur high maintenance costs and, accordingly, are not favoured except for applications such as green houses, workshops and the like. Where it is necessary to use refrigeration for cooling an economy cooling cycle, utilising up to 100% outside air (when conditions are favourable), shall be used. The use of sprayed cooling coils shall be considered (in conjunction with the economy cycle) to reduce refrigeration and re-heat requirements. Refrigeration plant shall be selected for economical part load operation. With multiple refrigeration equipment, various combinations of capacities shall be plotted against anticipated running costs to determine the most economic configurations whilst not compromising the systems performance, particularly at low system load. Where possible, the heat rejection from the refrigeration system shall be used for heating purposes. Radiant heating generally requires less energy than warm air heating. Heating hot water boilers shall not be used in domestic hot water systems. Hot water supply temperature used for heating shall be as low as practical to reduce system losses, but not to the point where it may effect boiler operation efficiency and life. Thermal storage may be used to store heat for re-use to reduce capacity and maximum demand. Waste heat recovery from exhaust air or gas, condenser water, etc. should be considered. Where it is necessary to condition large quantities of air for laboratories or special areas, air-to-air heat recovery devices shall be considered as a means of reducing plant capacity and running costs. Appropriate plant controls shall be selected to prevent excessive energy consumption. Refer to Section B4.7 'Controls & Monitoring' for details of the University’s requirements. Consultants, Project managers and Contractors shall consider the 'maintainability' of the plant. Ease of access to components requiring scheduled maintenance facilitates better maintenance procedures thus preventing excessive energy consumption by poorly maintained plant. Domestic hot water services shall be selected to ensure that the balance between energy source, location and long term running costs is properly evaluated. To ensure the most efficient operation of the hot water unit standing heat losses through long pipeline runs shall be avoided. Gas fired units shall be selected in preference to electric units and all heating pipe work shall be lagged. Stairwells should be designed and positioned to encourage use for vertical circulation in preference to lifts. B4.9.5 Management of Lighting The goal in the management of lighting is to gain maximum benefit from the system whilst minimising wasted energy. Consultants shall calculate installed lighting loads and submit these to the University for consideration as part of the design review process refer B4.1.3 'Design Review'. Design guidelines for lighting are set out in Section B4.3 'Luminaires'. Building lighting shall: - enable tasks to be performed quickly accurately and easily; - allow building occupants to work and move about in the building in safety; and - achieve the desired character of the interior. Lighting levels shall reflect a practical application of the requirements of the current issue of AS1680 to provide a safe, visually comfortable, working environment.
Lamp selection shall be made following consideration of the following: - colour rendition; - lamp lumen depreciation; - lamp shape; - strike/restart time; - ease of lamp removal for changing; and - lamp life and cost. Tungsten lamps may sometimes be suitable whereby careful light control and a high utilisation can be achieved. Fluorescent tubes are the preferred light source and the University has standardised on 36-Watt and 18-Watt units. Fixture selection shall be made after the following have been considered: - the efficiency of a fixture in space (co-efficient of utilisation); - the importance of having as low glare system in areas such as terraced lecture theatres, etc. (visual comfort probability); - resistance to dirt build up (luminaire dirt depreciation - LDD); - low glare diffusers should be used with acrylic prismatic lenses for fluorescent fittings. Opal diffusers shall not be used; - the recommendations of AS1680.1 regarding the minimum shielding angle of luminaires shall be followed where screen based equipment is used; and - the use of heat removal of air handling fixtures may permit the use of smaller more efficient cooling systems to maintain comfort levels. Minimisation of energy consumption shall be considered taking the following into account: - the balance between task and building illuminance; - availability of daylight lighting; - provision of switching controls to enable lighting to respond to daylight variations and room occupancy; - use and maintenance of high surface reflectances; - mounting height of luminaires; - appropriateness of fittings related to use; and - efficient exterior lighting. B4.9.6 Documentation Required To ensure that consultants are aware of the various factors that lead to significant improvements in energy performance, an Energy Evaluation Statement shall be completed when documentation is complete. The statement enables the University to review predicted energy use and to initiate recording, budgetary and energy operations throughout the building life. A proforma of the Energy Evaluation is included in Appendix B4.6.

Working temperature settings shall be in accordance with the BOMA guidelines. Hot water units shall be positioned in a readily accessible position for ease of maintenance. B4.11.7 Cisterns and Flushing Valves The use of exposed half flush cisterns is preferred in buildings solely occupied by University staff, or combination of staff and research personnel. Recessed cisterns shall be used wherever undergraduate use occurs. Flushing valves are preferred where toilets are subject to peak usage, eg. toilets adjacent to a lecture theatre or a large teaching laboratory. If flushing valves are installed, consideration shall be given to providing ease of access for maintenance purposes and sound attenuation. B4.11.8 Neutralising Chambers Consultants shall determine the type, quantities and concentration / dilution levels of chemicals to be discharged into the sanitary drainage system. Users must provide accurate information to assist consultants in determining the need for a neutralising chamber. The local water supply and drainage authority shall also be consulted regarding their requirements. If a neutralising chamber is required, it shall be located to provide easy vehicular access where pumping out or cleaning procedures are necessary. Neutralising chambers shall not be located in plant rooms. Associated dosing tanks shall be located where maintenance staff can gain access independently of any laboratory or office area. An adjacent cold water supply and general purpose outlet shall be provided for mixing purposes. Ventilation of neutralising chambers shall be such that any fumes do not re-enter the building. B4.11.9 Colour Coding Plumbing, electrical and mechanical subcontractors shall colour-code their services for identification.
B4.11.10 Stormwater Reticulation Consultants shall ensure that the entire stormwater reticulation system has ample capacity to cope with intense storms over a short period. Consultants shall check the existing stormwater mains to which a new building is to be connected to ensure that they are serviceable and in the correct location. Gutters, downpipes and discharge sumps shall be designed to minimise the likelihood or blockage caused by vegetable detritus. Refer also to B3.5.3 'Roof Drainage'. B4.11.11 Irrigation It is preferred that the landscape forming part of each project be suitably irrigated as determined by plant species. Where an irrigation system is required, the installation shall form part of the project and be adequately documented. Irrigation systems shall be separately metered and shall not form part of the cold water supply for a particular building. The University prefers that electronic control devices control irrigation systems. The issue of a centralised control system is currently under review by the University; therefore, consultants should discuss the matter with the Division’s technical staff. B4.11.12 Testing and Commissioning Generally, all testing and commissioning shall be in accordance with the requirements outlined in B4.1.7 'Testing and Commissioning of Services'. B4.11.13 Maintenance and Service Consultants should note that the specification shall require the contractor to meet the Division’s technical staff upon completion of the installation for suitable instruction regarding maintenance and servicing of the installation. B4.11.14 Documentation Required Consultants shall submit their calculations on the adequacy of the stormwater drainage system to the University for acceptance early in the design phase of the project. Draft tender documents shall be provided to the University in accordance with B4.1.3 'Design Review'. Operation and Maintenance Manuals shall be submitted to the University in a form and sequence outlined in B4.1.10 'Operation and Maintenance Manuals'. Works as Executed Drawings shall be provided to the University in accordance with the requirements of Clause B4.1.9 'Works As Executed Drawings'. All Certificates of Compliance shall be submitted to the University and bound into the O&M Manuals
