Hong Kong Science and Technology Parks Corporation

Background
The Hong Kong Science and Technology Park is a science park located in Pak Shek Kok, New Territories, Hong Kong. It has been planned as a research and development campus where High and New Technological firms can set up their bases. It is administered by the Hong Kong Science and Technology Parks Corporation.
The Hong Kong Science and Technology Park is being developed in multiple phases, each incorporating diverse Building Management System (BMS) solutions from different manufacturers. These systems operate independently within each building, lacking support for open protocols and integration into a unified platform. Transitioning all BMS systems to a single open system platform, potentially involving controller upgrades at both the Network Control Unit (NCU) and Direct Digital Control (DDC) levels, poses substantial capital expenses and operational disruptions.

Project Objectives
The primary goal is to establish a comprehensive BACnet protocol platform across all buildings in Phases 1, 2, and 3, focusing on the NCU level while preserving the integrity of the DDC level. This initiative aims to foster open protocol communication among buildings, thereby facilitating seamless system upgrades and expansions. By embracing the BACnet standard, end users will no longer be constrained by proprietary systems, enabling them to upgrade and extend their systems at their own pace. The new system will streamline monitoring, control, and alarm handling of existing BMS setups, ensuring a consistent user interface experience.
Project Achievement
We integrated the diverse BMS from different manufacturers across all buildings in Phases 1, 2 and 3 by establishing a comprehensive BACnet protocol platform. The integration involves 25 buildings, over 3,500 DDCs and 10,500 VAVs with over 210,000 points. The integrated equipment includes VAV, PAU/AHU, chiller plants, power analysers and various building services such as P&D.
