1.2 Project Description

Torrens Early Learning - Passive House

Torrens Early Learning is a long-day-care facility which provides early education and care for 89 children aged from 6 weeks to 6 years, and has a staffing element of around 20 carers/teachers /administration staff.

The facility consists of 2 separate buildings, (both 2 storey) linked by a large external deck and playgrounds and front entrance.

The first building has administration, commercial kitchen, dining rooms and a baby’s nursery space – this building was a re-adaption of the existing building’s footprint. The re-adaption reused the slab and services, retained brick fences, and boundaries, and rebuilt and re-developed the space. The building was built to the Passive House standard, but did not meet the final airtight criteria.

The second building is a certified Passive-House building – certified as Premium. The building was developed for solar performance – to face north, allow a roofline for maximum solar panels, to allow natural light into all learning spaces, and mobility access for children to all spaces and playgrounds. Careful attention was paid to windows and the distribution of light into classrooms, and importantly solar heat gain in winter, and the rejection of such heat in summer. The building consists of 6 large classrooms, and 3 bathrooms.

5 Construction details

5.1 Floor slab/basement ceiling

Part of the building has a concrete slab floor that is insulated above with 50mm Phenolic foam (Lambda 0.020 W/mK). The other part of the building has a timber suspended floor insulated with 240mm of fiberglass insulation (Lambda 0.043 W/mK).

Project Documentation Page 11 of 18 05/2020

5.2 Exterior walls

The walls are timber framed and insulated with 140mm of fiberglass batts (Lambda 0.035 W/mK).

Project Documentation Page 12 of 18 05/2020

5.3 Roof

The roof is made from timber rafters and insulated with 240mm of fiberglass batts (Lambda 0.043 W/mK). Above, it is lined with OSB, a weathertight membrane and then counter battens, battens and metal roofing.

Project Documentation Page 13 of 18 05/2020

5.4 Windows

The Windows and doors are Neuffer brand timber – aluminium framed, made of Eucalyptus and have an average Uf value of 1.03 W/m2K. The glazing is triple glazed Argon filled with low E coatings and laminated glass where there is the possibility of human impact. The average Ug is 0.60 W/m2K and g value 0.54. Barrier free thresholds were used in the bathrooms for wheelchair access.

6 Airtightness

Pro Clima Intello airtight membranes were used on the walls and ceilings for airtightness. These were taped to the windows, doors, and junctions with matching airtight tapes. Penetrations were sealed with grommets.

The building achieved an airtightness test result of 0.6 ACHn50. Main leakage areas were around penetrations for data cabling.

Project Documentation Page 15 of 18 05/2020

7 Ventilation systems

Three SystemAir heat recovery ventilation machines are used to service the building. The heat recovery efficiency is 77% and electrical efficiency is 0.22 Wh/m3. Fresh air is delivered to the classrooms and extracted in the bathrooms. Air is delivered via rigid metal ducting that is insulated in some areas with fiberglass batts.

8 Heating and cooling systems

Each classroom has an average area of 83m2 and is heated and cooled with its own reverse cycle air sourced heat pump with a capacity of 5 kW.

9 PHPP results

The project is the first of its kind to achieve the Passive House Premium certification in Australia owing to its very low energy usage and very large 30kW solar PV array.

10 Build cost

The construction cost was 2050 Euro/m2 of Treated Floor Area and that included the outdoor play area, shading devices and landscaping.

11 Experience

Some observations after the owner occupied the site for over 12 months:

“Working at Torrens is so comfortable, we rarely need to use artificial heating or cooling, and the constant temperature and quietness of the building (no external noise, no mechanical noise) makes for a relaxing work environment. The building feels fresh and the air is clean – even during poor weather – like the January smoky bushfire events when Canberra had the worst air quality in the world. “

“My other buildings cost me 9,000 Euro a year in electricity – whilst Torrens is only 21 Euro – and that is mostly from the administration fees for being connected to the electricity grid.”
