HASSELL - 61 Little Collins Street, Melbourne
HASSELL is a multidisciplinary architecture and design firm located throughout Asia and Australia. The objective for the HASSELL Studio base building was to achieve high daylight levels throughout the tenancy areas to ensure the lighting system efficiencies could be maximised and also to contribute positively to psychological and emotional conditions within the workplace relating to occupant wellbeing.
Features of Sustainable Lighting
- During the base building warehouse refurbishment, light wells and voids were created through the centre of the tenancy and window openings were increased to ensure increased levels of natural daylight (to a factor of 2.5% as referred to in the Green Star rating tool) were achieved to an average 60% of the tenancy (NLA)
- Given the higher ceiling heights of 4 meters, suspended lighting beams are placed 1300mm (directly) above workstation clusters using high efficiency fluorescent lamps
- Due to the high levels of natural lighting, the workstation clusters provide a range of Lux levels between 220 – 320 Lux at desk levels for all desks and dimmer control per cluster of desks. This allows their designers to control their specific environment within a grouping of 6 -8 staff whilst minimising product usage. Individual task lamping is not required
- Employee education process to ensure employees understand the benefits in glare reduction; occupant control and energy efficiencies of the design
- Obtained employee feedback through the initial 12 month period and conducted employee training in the use of the lighting systems and the studio operations
Lighting energy usage between 6 - 7 watts/m2; as compared to standard lighting energy calculations for commercial fit-out of between 10-15 watts/m2: approximate 30-60% energy saving.
HASSELL has undertaken a Productivity Study on their previous tenancy and new studio environment which is due for completion mid 2007.
Further refining of the lighting Lux levels will occur to provide the option for 180 Lux level and off settings, due to occupant feedback.
