Ainsworth Lake Recreation Hall is a multipurpose recreation hall, used for basketball, netball, badminton and other sports, as well as meetings, movies and theatrical performances located at Lennox Head, in Northern New South Wales, Australia. The building was designed in 2005 by architectural firm Allen Jack Cottier, replacing the obsolete indoor sports facilities.

Design
Lake Ainsworth's multi-purpose recreation hall uses eco-friendly design as its principle. The inspiration for the building was taken from a glass pavilion from the 1800s, in particular, the vision of Joseph Paxton for The Crystal Palace built for the Great Exhibition in 1851, and then moved to its present location in South East London. It was considered 'Winter Park and Garden under Glass'. Despite the inspiration drawn from this building, the recreation room at Lake Ainsworth must face the challenge of installing glass structures into different climatic conditions. Countries with a temperate summer climate are able to maintain a well-structured glass where it provides a wonderful quality of internal light, a vast space and shelter from the weather of those countries. However, in tropical or warm climates, glass palaces are less successful without extensive mechanical cooling and shading.
The design team must not only address Australia's climatic conditions, but also jointly build energy and environment efficiently, respect the site, and inspire for its users while facing tight budgetary constraints. Thus, the solution is achieved by utilizing the sheeting of hot polycarbonate sheeting onto the roof and walls where only a small portion of the heat energy (sun) is displaced. Detailed modeling proves that Danpalon (TM), an insulated UV-resistant material, can be used on a steel frame to incorporate central ventilation for fresh air cooling. Very low energy use and mechanical ventilation are not required.
This design includes three colorful pods that are enclosed in boxes like luminous tubes that are alive. The main area can be closed at both ends and reacts to outdoor weather through a programmed grid sequence and roof vents. At night, the transparent façade of the building shines like a lantern in the landscape when used as a theater.
According to project and design architect, Michael Heenan, the real excitement of this building is how it reflects the colors of morning and evening light, as well as the surrounding bushes. "It's really about light, the building's skin is very smooth, and therefore it reflects whatever is around it."

Materials
Danpalon (TM), a high-tech polycarbon, is used for roof walls and panels that allow up to 90% infiltration during the day. Low energy usage and no mechanical ventilation required.
Originally, it was clear Danpalon (TM) Muticell was proposed, but custom material designs that vary in terms of light and solar transfer properties are suggested by SolarSpace (TM) instead. The Danpalon Heatstop, a reflective gray color, is ultimately chosen for overall efficiency but in addition, the solar transmission class varies and fits the orientation of the building. The resulting solution is to use 1% of the sun's transmitting material on the roof, 3.5% of the solar transmission on the east and west walls, and the 18% solar base transmission in the north and south elevations. Less heat is transferred to the building and artificial lighting is not necessary at all during the day.
The floor system uses concrete slabs with sprung wooden floors for basketball, ball nets, volleyball, and wall climbing.
