Shepherds Bay
This project consisted of 9 multiunit residential buildings. The domestic hot water plant for each building consists of a single pass heat pump hot water system, design to minimise electricity use during peak electricity tariff periods.
Using a heat pump domestic hot water plant, in lieu of a business as usual gas plant, resulted in a significant reduction in gas distribution infrastructure. The lower energy intensity of the heat pump solution also resulted in an improved Basix rating.
This superbly master planned waterside village is brought to you by Holdmark, a developer of high-quality apartments and living precincts in Sydney's best locations. For more than 25 years, Holdmark has built a reputation for creating thriving communities from the ground up.
Shepherds Bay reflects the company's commitment to creating spectacular living environments and outstanding investment opportunities that enhance the urban landscape and the way people live.
The works by Automation Industries involved the design and implementation of
-
New Central Heat Pump Hot Water Plant (CHWP)
-
Embedded electricity metering system
-
Hot Water metering
-
Cold Water Metering
-
Recycled Water metering
-
Meter data management
-
Compliant Carpark ventilation with Carbon Monoxide (CO) monitoring
Automation Industries designed and installed a heat pump hot water system which is capable of load shedding during peak electricity tariff periods. The new hot water system is independent of other mechanical services and is completely managed by the DEOS control system.
Automation Industries worked with Flow to implement a metering and billing system.
The building electricity network is an embedded electricity network managed by Flow Systems.
The Metering system includes electricity metering for all apartments, commercial tenancy and common property meters.
It is implemented with a utility grade Landis+Gyr Electricity metering system, and meter data management is integrated to Automation Industries fully managed cloud infrastructure.

Challenges
The challenges on this project were all related to designing systems to align with current architectural designs and builders time constraints, these challenges included -
-
The Air-cooled hot water system had to be designed to fit into basement plant rooms – considerations for space, acoustics and ventilation were required to be met.
-
The metering system architecture had to align with current electrical designs and cable risers.
-
The carpark ventilation plenums had to be designed to share the HWP exhaust with carpark CO to take priority.
-
Co-ordination of new Hydraulic and EEN designs between the builder and their subcontractors.
How We Helped
Metering systems
On this project Automation Industries have designed, supplied and installed a multi-utility metering system to meter and provide the client with Hot and Cold water usage, recycled water usage and electricity usage for each apartment and commercial tenancies, also providing meter data reports for billing.
Central hot water plant
Automation Industries have designed and installed a highly efficient centralised closed loop heat pump system with off-peak storage for each stage.
Carpark Ventilation
The carpark ventilation system consists of Carbon Monoxide control strategies and Variable speed drives on the exhaust fans. This system is also managed by the DEOS BMS and integrates to the Hot Water Plant room exhaust system.
The Technical Details
The EEN provided by Automation Industries consists of landis+Gyr Smart meters connected to an Automation Industries AMI (advanced metering infrastructure ) the billing data is collected and processed by Automation Industries highly secure MDMaaS (Meter Data Management as a Service). Billing data is managed and provided by Automation Industries.
The water metering system provided by Automation Industries consists of NMI approved smart MBUS water meters.
The water meters are also connected to Automation Industries AMI system, and billing data is securely transported via IPsec VPN and processed by our MDM service.
Control Systems
Control of the mechanical plant this is achieved through Automation Industries Digital Energy Optimization System (DEOS). The DEOS software is continually analysing site conditions and plant performance to optimise plant efficiency, through changing the heat pumps configuration from series or parallel, varying flow rates and heat exchanger optimisation.
During shoulder and off-peak, the DEOS system will run the plant to produce hot water for the building and hot water for the storage tanks, the tanks are sized to provide sufficient capacity/buffer for the heat pumps to be shut down during the peak electricity period. (2PM-8PM) Due to the hot water plant not running in peak periods, it adds no additional demand or capacity changes to the building.
