All Consultancy Projects
IES Consulting were commissioned by Penston MEP (M&E Consultants) to carry out integrated building performance modelling for two Jaguar Land Rover facilities at its Software Engineering Centre in Shannon, Republic of Ireland.
The Software Engineering Centre in Shannon is branded as Jaguar Land Rover’s hub for autonomous and next generation vehicle projects. The centre will develop new technologies to support electrification and self-driving features on future Jaguar and Land Rover vehicles.
IES Consultants used its world leading VE software to analyse the performance of a four-storey office development and a 3,100m2 warehouse and lab facility situated at the Software Engineering Centre. Both projects were pursuing certification via LEED v4 Interior Design and Construction – Commercial Interiors.
This 4-storey development consists of a total occupied floor area of 4105m2 and includes office space, meeting rooms lounge areas and lab areas.
Using IESVE to apply the building performance rating method (BPRM), IES consultants were able to determine the proposed energy consumption for the office development and compare it against the ASHRAE 90.1 2010 baseline model. This included assessing and applying a number of energy efficiency measures (EEMs) to the model, and analysing various options to ensure a high-performance building envelope. In doing this, IES consultants were able to achieve a total energy cost saving of 24.5% over the ASHRAE 90.1 2010 baseline model. This saving meets the minimum 3% LEED EAp2 prerequisite and also achieves 24 LEED EAc1 points, which led to the building achieving a LEED Gold certification.
The primary HVAC system for the new building consists of two roof mounted OAHU feeding the restrooms and kitchen. The tenant areas are served by zone level FCU’s with outdoor air supplied by zone level heat recovery units. Hot water is supplied by two high efficiency natural draft boilers each with a heating capacity of 327kW. Chilled water for the FCU cooling coils is supplied by two air cooled scroll chillers each with cooling capacity of 308kW. Chilled water is circulated via a number of VSD secondary pumps and CV primary pumps.
Additional energy efficiency measures implemented are as follows:
Warehouse and Lab Facility
This facility is used for the testing and analysis of Jaguar’s electric and automated driving vehicles in support of electrification and self-driving elements on future Jaguar and Land Rover vehicles. The warehouse/testing facility takes up the majority of the building floor area at 2,300 m2. The remaining floor area is comprised of offices/research labs, meeting rooms, restrooms and a staff kitchen.
Using the same modelling process as outlined above, IES consultants were able to demonstrate that implementing a combination of energy efficiency measures along with a high-performance building envelope would lead to a total energy cost saving of 28.9% for the building. This facility also achieved LEED Gold certification.
The building has been designed for high energy efficiency by employing a number of low energy design strategies. The warehouse is heated via high efficiency gas-fired, air heaters with axial fans that operate in parallel with de-stratification fans that significantly improve the heat distribution effectiveness. It is ventilated via a mixed mode mechanical ventilation system comprised of exhaust fans with variable speed drives and low-level intake louvers that include motorised dampers linked to air quality sensors. The system automatically adjusts outside airflow to ensure adequate ventilation is provided at all times. Occupants also have access to operable windows for local comfort.
The office area is conditioned by a high efficiency Variable Refrigerant Flow (VRF) air conditioning system. Outside air is provided by an air handling unit with high efficiency energy recovery. LED lighting is provided throughout the building. Lighting control is provided by the “Enlighted” lighting control system that incorporates both PIR occupancy sensing and digital ambient light sensors for daylight harvesting. A photovoltaic system comprised of 18m2 of monocrystalline modules contributes in reducing the buildings energy costs by over 1%.
