Webinar: Managing Historic Campus Facilities

Managing Your Historic Campus Facilities in Today’s Resource-Constrained Environment

  • Strategies for Historic Management
  • Sustainable Integration
  • HVAC in Historic Buildings

This, the first-ever collaborative webinar between APT International and The Society for College and University Planning (SCUP), will be held 2.00-3.15pm (Eastern time) on 20 October 2020 [that’s 5.00-6.15am on 21 October 2020 AEDT]. And it’s free to register.

How are you addressing your campus’ historic facilities with so many competing needs for limited resources? This webinar will outline strategies for the management of historic properties on college and university campuses, with guidelines, standards, and best practices to address a wide range of concerns dealing with historic facilities.

Preservation of your historic facilities can also be an important part of your long-term plan for a sustainable future for your campus and the planet. Upkeep, renovation, and repurposing of existing structures are seen by many as an essential part of flattening the carbon curve. We will consider examples of successful efforts to integrate sustainability, preservation, and practical re-use of older facilities.

HVAC upgrades in historic buildings present numerous challenges that are only amplified when working in a campus setting. The process for HVAC projects in campus historic buildings will be discussed along with the newest challenge of upgrading systems to provide safer interior environments to prevent the spread of coronavirus.

Whilst the timing is challenging for Australian attendees, this is an opportunity to hear from leaders in the field in North America.  Click here for more information, and to register for this free webinar.

Heritage Technical Codes – lime mortars

The Heritage Council of Victoria has launched two new Heritage Technical Codes. These were developed in partnership with Heritage Victoria, on the topics of lime mortars for the repair of masonry (HTC1) and repointing with lime mortars (HTC2).

These Codes are the result of a pilot project to test a new approach whereby the BCA Performance Solution process is applied to support the use of building materials and techniques compatible with heritage fabric. The Performance Solution process allows for the use of alternative construction codes (including overseas codes), instead of the Australian Standards, so long as these satisfy BCA Performance Requirements. The project aimed to do this by developing specific heritage codes: the Heritage Technical Codes.

The project was prompted by long-expressed concerns by the Heritage Council’s Technical Advisory Committee that the Building Code of Australia’s (BCA) Deemed-to-Satisfy Provisions (including the Australian Standards) are generally not well suited for heritage places, and in many instances their application will damage heritage fabric. The absence of relevant Deemed-to-Satisfy Provisions for historical buildings has created problems for their management and maintenance, with Australian Standards frequently quoted to justify the removal or destruction of heritage fabric, or the use of replacement materials that will cause long-term damage.

The first two Codes have been produced as part of a pilot to enable the Heritage Council and Heritage Victoria to better understand the challenges and opportunities of developing such Codes, and also to allow for stakeholder feedback.

The Codes can be found on Heritage Victoria’s website: https://www.heritage.vic.gov.au/research-and-publications/permit-policies

More information about the pilot project and where to provide feedback is available on Heritage Council’s website: https://heritagecouncil.vic.gov.au/research-projects/heritage-technical-codes/

Australian contributions to the Building Technology Heritage Library

The start of 2019 marked the beginning of a project to add new Australian, European and American documents to the Building Technology Heritage Library (BTHL) supported by the APT Australasia Chapter. These documents come from the collection of Professor Miles Lewis, retired professor of architectural history from the University of Melbourne, and well-known to many of our members here in Australia.

Lewis’s passion for vernacular and urban architecture finds tangible form in his personal library of more than 2,500 documents, which includes many early European documents on building technology and construction. He is also an avid collector of architectural trade catalogues, a principal component of the BTHL. Architectural concrete and prefabricated buildings are but two topics that will be enriched by his contribution.

Professor Miles Lewis and APT Australasia Chapter Convenor Dr Donald Ellsmore were successful in getting a grant from the Vera Moore Foundation to permit the digitisation project, which will be completed by mid-2019. Additional technical support for the digitisation was provided by the University Digitisation Centre at the University of Melbourne.

In the course of this project, the BTHL went beyond the 10,000 item mark, as described in this article from Traditional Building.

Below are samples of documents from Lewis’s collection now incorporated in the BTHL.

Longford Academy – Planning a strong future in new hands

This year the Longford Academy will celebrate its tenth year.  And this brings exciting changes for the future of these hands-on building conservation courses at the World Heritage Sites of Woolmers and Brickendon Estates in Longford, Tasmania.

Donald Ellsmore, Convenor of the APT Australasia Chapter, has been the driving force in initiating and coordinating the Longford Academy for a decade, but he now wants to focus on other passions in his life and gently lessen his commitments to LA. So others involved with the Longford Academy, and equally passionate about what can be achieved in the field, met before the Master Classes last August for a 2 day planning exercise to review the past and plan for the future.

Arising from that session is the formation of the Longford Academy Board with Greg Owen as Chair and Coordinator of the 2019 courses, and Donald Ellsmore, David Young, Elisha Long, Brian Maxwell, Anthony Mitchell, Marty Passingham, Gary Waller and Ray Wiltshire working together as a Board.

The APT Australasia Chapter has agreed to continue to support the Longford Academy, but the Longford Academy Board will now be responsible for organising and running these hands-on building conservation courses.

Probably the most exciting thing to come out of the future planning is David Young’s proposal to commence, at Longford in 2020, a Summer School in Building Conservation similar to those he formerly ran at the University of Canberra. Everyone in building conservation in Australia has either been to or aspired to attend that course, and now it will be available again, in an updated format, in World Heritage-listed surroundings.  The next edition will be offered from 9-15 February 2020. Watch out for more information about this.

The Autumn ‘Practical Building Conservation’ course will run again in May 2019, and flyers will be out about that soon, with the Spring ‘Specialist Masterclasses’ now planned for the first week in September 2019.

APT Australasia Chapter has created this page containing more detail on the courses now on offer at Longford Academy, and how to choose which is best for you.

Keep an eye out for future flyers and newsletters, but if you have any questions in the meantime contact Greg Owen on (03) 5728 6694 or by email.

Limestone and Lime Building Techniques in Puglia, Italy

Report on APT Australasia Chapter members’ investigation of limestone and lime building techniques in Puglia, Italy

In late October 2018, a group of Australian and New Zealand members met in Ostuni, Puglia, to immerse in the traditional building culture of lime and limestone that are quintessential features of cultural places in southern Italy. The area is dominated by vast expanses of ancient olive groves punctuated with white limestone hill towns, masserie (fortified farm houses) and trulli (conical-roofed structures).

Lime and limestone were the theme of the week-long immersion program, which was facilitated by Peter Lewis (paint manufacturer and owner of the masseria ‘Mangiamuso’ near Ostuni), his architect Aldo Flore (Ostuni-based architectural conservation specialist), other specialists, property owners and lime manufacturers.

On day one, the group was introduced to the main site of the study program, Mangiamuso, which was nearing completion of works to adapt it for occupation by the Lewis family. The sensitive conservation program, designed by Aldo Flore, has converted the place into a very tasteful and comfortable home, without diminishing the historic character of the 300-year-old masseria or substantial parts of the property, including two below-ground frantoii (olive mills), which remain untouched by the makeover.

On day two, Paolo Albergoni, co-owner of the impressive masseria, ‘Garzia’, gave the group detailed historic information about the history of masserie in Puglia. We learnt about the historical circumstances leading to the common practice of locating all the olive oil processes and product below ground for security. Subsequent changes in agricultural practices led to developments of outlying barns, dairies and other structures, and the conversion of many of the below-ground former oil processing and oil storage areas for other uses. Now, hardly any of the masserie continue to function in the traditional manner. Many have been converted for tourism or as residences for wealthy owners.

On day three, Aldo Flore led the group to a small lime production plant at Caravigno, where limestone is calcined in a traditional bottle kiln fuelled with wood products including plywood and chipboard, mostly recovered from demolition sites.

The freshly burnt quicklime is fed into a rotary drum slaking tank from which putty is dumped into large settling tanks, where it remains until it is milled and bagged for sale in a range of putties and mortars for masonry and plaster works.

From Caravigno, we travelled to a more extensive lime production plant at Fasano, where waste wood from wood-working processes at the site is the source of fuel for four bottle kilns. The processes are the same as at Caravigno, though on a larger scale and with further post-production of specialist products including lime paints and decorative finishing material such as cocciopesto (lime with fine-ground terra cotta).

After visiting the lime works at Caravigno and Fasano, we inspected a trulli conservation project with Aldo Flore near Locorotondo. Here it was enlightening to obtain first-hand details of how the traditional cone-shaped structures – which were entirely basic and primitive at the time of their construction – are being adapted to address the architectural challenges of climatic control, damp management and seismic stabilisation. Aldo has managed many similar issues in Puglia and has emerged with specialised knowledge of the building type and adaptation and re-use.

The renowned food and wine of Puglia featured in the group’s next stop where a superb late lunch was served by chef Stefano and his infamously grumpy cameriere at Osteria del Cocopazza (pazza means crazy in Italian) in the centro storico of the hill town of Martina Franca. Time was limited for an extensive walking tour of the historic centre but good memories of the gorgeous historic city will re-surface again when memories of the lunch eventually settle!

On day four, the group got seriously into trulli and more food at Casa Cilona, near Ceglie Messapica with Puglia-based American architect Amanda Roelle, who provides educational programs on trulli, and host/chef Tonino. Amanda led the group on a walking tour of a collection of abandoned, though largely intact, trulli in a gorgeous bucolic landscape at Pascarosa.

After pranzo (lunch) it was down to work with Mario the trullaro (trulli builder), shaping and laying chianche (stone shingles) to construct a cono (conical roof).

At the end of the day Amanda made a more formal illustrated presentation on the typology and construction details, followed by a memorable meal.

On day five, the group travelled to Matera the remarkable historic city of ‘Sassi’ (ancient quarters) built into a rugged gorge, in the adjoining province of Basilicata. Sadly the place was densely packed with visitors on the day, a public holiday, and it became difficult and uncomfortable to navigate around the site. Our guide, Dora, provided a very informative tour of the ancient city, explaining the history, decline, shame, recovery, gentrification and tourism appeal. However, the crowding and lack of easy access to important features compromised the experience. A year ago the experience was different: the place was tranquil. Since then, efforts to promote the World Heritage listed place, including selecting it as European Cultural City of 2019, have tipped the balance towards tourism exploitation. Even so, Matera was and is a special place to visit.

On day six, we travelled to Alberobello, also World Heritage listed, containing a high concentration of trulli. The experience was slightly more relaxed than Matera and highly rewarding, but Alberobello also is labouring under the weight of visitors and there were lots of them on that holiday weekend. The nearby gorgeous small hill town of Locorotondo, featuring a concentration of commerse (barrel vaulted limestone terraces with chianche roof coverings) was also bulging at the seams due to the holiday visitors. Our visit there was truncated by the complications of holiday traffic.

At the end of the week, the group dispersed to other parts of Italy (Lecce, Naples, Rome and Sicily) to continue their Italian experiences, or on to other destinations (USA, Germany and Thailand) and home (Australia and New Zealand).
