PROJECT BRIEFOur client was planning to build a new manufacturing facility in Asia and requested a complete review of the concept design with evaluated options to optimise the energy performance of the facility.
EECO2 provided a report, focused in detail on the HVAC system, but also addressing related engineering and utility services for the facility.
Review of existing scheme to provide a recommendation for a more sustainable approach to building services including HVAC systems:
GMP qualification principles
Building design principles including loads
GMP & non GMP areas
Building controls, cooling, heating and dehumidification systems
Opportunities for heat recovery and renewables
Low energy ventilation including: filters, motors, fans and laboratories
Enhanced / integrated renewable strategies
Metering and monitoring strategy for future energy control
A building energy simulation model was created to evaluate design options on life cycle costs and energy consumption and included modelling of variations in building fabric and construction standards, air change rates and specific fan power
The focus of detail in the report is on the HVAC. However, there is some discussion and recommendations made for best practices on other utility systems including refrigeration, compressed air and dust collection.
From design optimisation
From design plus HVAC optimisation
A 74% energy reduction was found to be achievable through risk based approach to air change rates and incorporating high efficiency air handling plant, refrigeration plant and renewable heating technologies.
