title: The Long Bay Restaurant site, R10/1374: Volume 1, the archaeology (HNZPTA authorities 2015/19 and 2016/81): Report to Heritage New Zealand Pouhere Taonga and Auckland Council

authors: Campbell, M

abstract: Auckland Council had proposed refurbishing the Long Bay Restaurant at Long Bay Regional Park (Lot 2 DP 54616), amounting to a near full rebuild of the structure apart from the in situ foundations. Council began the project in mid-2013 with the partial demolition of the existing structure and sawing of the concrete floor slab to install new utilities. Following the discovery of human remains beneath the floor slab on 2 July 2013, work was halted. The remains were inspected by the New Zealand Police who confirmed that they were pre-European kōiwi tangata. An assessment of the site was then undertaken by Beatrice Hudson of ArchOs Archaeology (Hudson 2013) and the find was recorded as site R10/1374 in the New Zealand Archaeological Association (NZAA) Site Recording Scheme (SRS) (this site number applies to any other archaeological features associated with the wider area). Auckland Council applied to the New Zealand Historic Places Trust (now Heritage New Zealand Pouhere Taonga, HNZPT) for an archaeological authority under section 18 of the Historic Places Act 1993 to undertake archaeological test excavations to investigate the nature, extent and condition of the site, and how it would be affected by the proposed development project. Authority 2014/506 was granted on 28 November 2013 and the investigation was carried out on the 20th and 21st of January 2014 (Campbell et al. 2014) (the 2014 excavation is summarised in Chapter 3).

Auckland Council then applied to HNZPT for an authority under section 44 of the Heritage New Zealand Pouhere Taonga Act 2014 to modify or destroy any further material found during the refurbishment project, including associated car parks and footpaths. Authority 2015/19 was granted on 7 August 2014 and works resumed. On 6 November 2014 further kōiwi were found within the project footprint and work once again ceased. 

Following extensive consultation with mana whenua and HNZPT, Auckland Council determined that the refurbishment would continue but it was agreed that the entire footprint of the development would be cleared archaeologically in order to provide assurance that no further kōiwi would remain within the project area. As the scope of the archaeological investigation had changed, a new archaeological authority, superseding authority 2015/19, was required and a full archaeological assessment of efects was also required in support of the authority application (Campbell and Hudson 2015). Authority 2016/81 was granted by HNZPT on 25 August 2015. This report fulfils the conditions of both authority 2015/19 and 2016/81.

Excavation began on 5 October 2015 with site clearance and removal of the concrete pad but not the ground beam foundations, while full excavation commenced on 12 October under the direction of Matthew Campbell (Excavation Director, CFG Heritage) and Beatrice Hudson (Osteologist, ArchOs Archaeology). Excavation continued until 3 November, by which stage kōiwi of a further 10 individuals had been found, bringing the total to 12. Following an onsite hui on 4 November between representatives of mana whenua, HNZPT, Auckland Council and the excavation team, the excavation was halted but mana whenua requested that the 3 possible burials that had been located but not excavated be lifted, and on 9 November the site was shut down. At a second on site hui on 9 December Auckland Council announced that they had resolved to cancel the restaurant project, but mana whenua expressed a desire that the 13 x 12 m excavation area opened up at the time be excavated to a sterile layer to lift all kōiwi. Excavation resumed on 18 January 2016 and continued until 4 March, when all kōiwi and archaeological deposits and features had been excavated.

title: Evaluation of a stratified tank based heat recovery loop via dynamic simulation

authors: Schlosser, Florian

abstract: Prerequisite for hot water recovery in the dairy and beverage industry is the use of heat storage, such as stratified tanks. Total Site Heat Integration enables the targeting of heat recovery potential, the concrete identification of suitable sinks and source profiles and the dimensioning of intermediate circuits and storages. For a cost and energy efficient storage, the aim to maintain stratification by suitable thermocline control management. Dynamic simulation enables a reliable estimation of energy savings and correct storage/control design considering the changing operation times, source and sink loads as well as thermal inertias. This poses two challenges: model accuracy and acceptable simulation time. A stratified tank model with Variable Layer Height (VLH) is evolved reducing numeric diffusion effects. A sensitive analysis shows the increased accuracy with acceptable simulation time. As part of a case study, thermocline growth due to numeric diffusion is reduced up to approximately 35 % by a VLH model. The model is simulated for a case study in the dairy industry. It is shown that up to 94 % of the total heat recovery target can be achieved by the modelled heat recovery loop based on a stratified tank and the applied system control.
