5 Star Greenstar and a 5 Star NABERS Energy rating

42 Honeysuckle Drive is a new mixed-use precinct which combines commercial office space with the Little National Hotel. The development will be Newcastle’s first Cross Laminated Timber (CLT) commercial building and aims to set new environmental standards for the Newcastle market, with a commitment to a 5 Star Greenstar and a 5 Star NABERS Energy rating. The project aims to bring commercial investment and boost the city’s economy.

Holmes worked on the commercial portion of the building, providing fire engineering and structural fire engineering services. The structural fire engineering analysis focussed on determining whether the mass timber structure is sufficient to maintain stability in the event of a fire. Advanced finite modelling was undertaken to determine the heat transfer and damage to the CLT floor slabs and glulam timber beams throughout the building. Holmes justified the design and demonstrated the robustness of the timber building under fire exposure. Our team of specialist engineers developed performance solutions to address several non-compliances in the building which included reduced FRL for the retail areas, rationalised zone smoke control, and undertaking CFD modelling to address rationalised stair pressurisation and travel distances within the carpark portions.

Additionally, our team assessed the risk of fire spread via the external sky signage of the Little National Hotel which is designed with a limited amount of combustible material. Holmes demonstrated that the sky signage is unlikely to contribute to the risk of fire spread to and from the building.
