Australia’s aged care sector is undergoing a construction boom driven by an ageing population, Royal Commission reforms, and updated Aged Care Quality Standards. Every new residential aged care facility (RACF) and retirement living village requires MEP (Mechanical, Electrical, and Plumbing) systems that balance resident comfort, clinical care requirements, and operational efficiency. Unlike standard residential construction, aged care MEP design must accommodate vulnerable occupants who are sensitive to temperature extremes, require assisted living infrastructure, and depend on essential services continuity for life safety.
This guide covers the specialist MEP drafting requirements for Australian aged care and retirement living facilities, including individual room climate control, nurse call and emergency systems, hot water safety, accessible amenities, and compliance with the Aged Care Quality Standards, NCC 2022, and relevant Australian standards. Whether you are an aged care developer, MEP consultant, or building services contractor, this resource provides the technical foundation for delivering compliant, resident-focused aged care facilities.

HVAC for Resident Comfort and Care
Individual Room Climate Control
Aged care residents spend the majority of their time in their rooms, making individual temperature control a critical comfort requirement. The HVAC mechanical drafting must document room-by-room climate control systems — typically fan coil units (FCUs), variable refrigerant flow (VRF) indoor units, or ducted split systems — with individual thermostatic control accessible to mobile residents and nursing staff. Design temperatures should accommodate the higher thermal sensitivity of elderly occupants, typically targeting 22–24°C in summer and 20–22°C in winter.
Infection Control Ventilation
Post-COVID aged care design places increased emphasis on ventilation for infection control. MEP documentation must address outdoor air ventilation rates exceeding AS 1668.2 minimums (many operators now target 10+ L/s/person in common areas), HEPA-filtered air supply for isolation rooms, pressure relationships between corridors and resident rooms, and air change rates in clinical treatment areas. These requirements overlap with healthcare MEP drafting standards, reflecting the increasing clinical acuity of aged care facilities.
Common Area and Back-of-House HVAC
Aged care facilities include diverse spaces with varying HVAC requirements: dining rooms (high occupancy density, kitchen adjacency), activity rooms (flexible use), hair salons (exhaust for chemical vapours), commercial kitchens (kitchen exhaust per AS 1668.1), commercial laundries (heat and moisture extraction), and staff areas. Each zone requires dedicated HVAC documentation coordinated within the building’s central plant system.
Electrical Systems for Aged Care
Nurse Call and Emergency Systems
Nurse call systems are a fundamental requirement for residential aged care facilities, mandated by the Aged Care Quality Standards. Electrical drafting must document call button locations in every resident room (bedhead and bathroom), corridor dome lights and display panels, staff pager/mobile integration, and system integration with building management and fire alarm systems.
Essential Services Classification
Aged care facilities classified as Class 9a or 9c under NCC 2022 require essential services power provisions similar to healthcare facilities. AS/NZS 3003 mandates emergency power supply for life safety systems (emergency lighting, fire detection, nurse call), with generator backup for extended outages. MEP electrical documentation must clearly distinguish essential and non-essential circuits through the distribution system, from main switchboard to final sub-circuits.
Assisted Living Technology
Modern aged care facilities incorporate smart building technology including automated lighting with motion sensors (for fall prevention in corridors and bathrooms at night), door access control, CCTV for common areas, wander-management systems (for dementia care units), and building management systems (BMS) for HVAC optimisation. The electrical and data documentation must coordinate these systems within the overall MEP design.
Hydraulic Services for Aged Care
Hot Water Safety
Hot water scalding is a serious risk for aged care residents with reduced sensation or cognitive impairment. AS/NZS 3500.4 and AS 4032.1 mandate thermostatic mixing valves (TMVs) limiting hot water delivery temperature to 45°C maximum at all accessible outlets in aged care facilities. Hydraulic drafting must document TMV locations, storage temperatures (60°C minimum for Legionella control), circulation system design, and temperature monitoring points — balancing scalding prevention with Legionella risk management.
Accessible Amenities
Every resident room requires an accessible bathroom compliant with NCC Part D and AS 1428.1 (Design for access and mobility). Hydraulic documentation must coordinate accessible shower drainage (hobless entries, minimum 1:60 fall), grab rail locations (coordinated with wall-mounted services), accessible basin heights, and toilet cistern arrangements. The repetitive nature of aged care room design makes BIM templates particularly efficient for documenting these standardised layouts.
Commercial Kitchen and Laundry
Aged care facilities typically include commercial kitchens serving 60–150+ residents and commercial laundries processing significant volumes of linen and personal clothing. Hydraulic documentation covers kitchen plumbing (similar to hospitality fitout requirements), grease management, laundry water supply (hot water demand for commercial washing machines), and wastewater treatment where applicable for regional facilities not connected to sewer.
Fire Safety for Aged Care
Sleeping Area Protection
NCC 2022 classifies residential aged care as Class 9c, requiring fire safety measures that protect sleeping occupants who may have reduced mobility, hearing, or cognitive awareness. MEP fire services documentation must address sprinkler systems throughout (AS 2118), smoke detection in every resident room and corridor (AS 1670), emergency warning and intercommunication (EWIS) with visual as well as audible alarms for hearing-impaired residents, and smoke compartmentation to allow staged evacuation. BIM coordination ensures fire-rated construction aligns with services penetrations.

Frequently Asked Questions
What NCC classification applies to aged care facilities?
Residential aged care facilities are classified as Class 9c under NCC 2022. This classification requires specific fire safety measures (sprinklers, smoke detection, EWIS, compartmentation), essential services power provisions, and accessibility compliance. Retirement village independent living units may be classified as Class 1b or Class 2 depending on the level of care provided.
What hot water temperature is safe for aged care?
AS 4032.1 limits hot water delivery temperature to 45°C maximum at accessible outlets in aged care facilities. Water must be stored at 60°C minimum to prevent Legionella growth, with thermostatic mixing valves (TMVs) reducing the temperature to safe levels at each outlet. MEP drafting documents TMV locations, monitoring points, and circulation system design.
Do aged care facilities need individual room HVAC control?
While not strictly mandated by NCC, individual room temperature control is expected under the Aged Care Quality Standards (Standard 5 — Organisation’s service environment) and is considered best practice for resident comfort and dignity. Most new aged care facilities specify individual FCU or VRF units per room with resident-accessible thermostat controls.
What nurse call system requirements apply to aged care?
Aged Care Quality Standards require reliable nurse call systems with call buttons in every resident room (bedhead and bathroom), corridor display, and staff notification. Systems must be documented in the electrical drawings with conduit routing, power supply, battery backup, and integration with fire alarm and BMS systems. AS/NZS 3003 provides guidance for healthcare-grade nurse call installations.
How does BIM help with repetitive aged care room design?
BIM enables creation of validated room module templates that can be replicated across 60–150 rooms with consistent MEP coordination. Once the template room is fully coordinated (HVAC, electrical, hydraulic, fire, nurse call), it can be propagated across the building with floor-specific adjustments, reducing drafting time by 50–70% compared to individual room documentation.
Can existing aged care facilities be upgraded using Scan to BIM?
Yes. 3D laser scanning captures existing building conditions without disrupting resident care. The scan data is modelled in Revit to create accurate as-built models for planning MEP upgrades — such as adding sprinkler systems, upgrading HVAC for infection control, or installing nurse call systems in older facilities that need to meet current Aged Care Quality Standards.
