Unit 13

1. Read and translate the text lightining and ventilation

Significant energy savings are also achieved through the use of natural lighting and ventilation, as well as the incorporation of automated supplementary lighting.

Energy efficient fixtures, fittings and appliances have been incorporated into The Grove fulfilling a key objective of providing a tangible real-life example of sustainability in action.

The interior lighting of the building consists predominantly of energy efficient fluorescent T5 lamps with dimmable daylight harvesting controls. The lighting in infrequently used areas is monitored by motion sensors that turn off or dim lighting as required. Zone relevant dimmer controls are used to suit usage and prevailing ambient light conditions. Individual workstation lighting consists of energy-efficient Z-Bar LED task lights and floor lamps, as well as Hafele LED desk lights.

External lighting uses a combination of LED and metal halide lights with photo sensor controls to turn area lighting on or off as necessary.

Each of these energy efficiency measures has a real and measurable impact on reducing electricity consumption and associated greenhouse emissions. It is estimated that the dimmable lighting control system at The Grove will result in electricity savings of approximately 17,000kWh per year, which translates to a reduction of around 14,000kg in greenhouse gas emissions annually.

Natural lighting and ventilation is provided by: - A 1m high continuous roof light for the library to maximise natural light and ventilation within the centre library space. - A roof light/clerestory (1.2m high x 9.5m long x 1.5m wide) in the foyer area to maximise natural light and ventilation above the stair of foyer. - Nine ‘sky domes’ to illuminate the corridor and internal spaces in the Shire administration building and community nursing room. - High level glass louvers will allow natural cross ventilation and night cooling of the library space.

It is estimated that the natural lighting alone will result in energy savings of approximately 11,000 kWhrs each year.

This translates to $1,600 per year at current electricity prices, and $4,000 per year at anticipated future electricity prices.

In addition, the basement car park has been designed to utilise natural ventilation so as not to require mechanical assistance.

  1. Read and translate the text comfort and conveniences Why comfortable flooring is so important

One of the main concerns for any floor is how comfortable it is for you to walk on. Whether this is in shoes, socks or bare feet, it will make a huge difference to how much long term value you get from your floor. There are a huge range of textures and feels, even among the same types of flooring surface. A thick plush carpet, for instance, gives a completely different sensation underfoot compared to one of a shorter pile.

You will also want a floor surface to not only suit your needs now, but those you might have in the future too. Comfort covers a variety of things like texture, slip resistance, heat retention, bounce and hardness – all will have a direct impact on how you walk on the floor and your enjoyment of it.
