COOLING BY DESIGN
Cooling and efficient temperature control is our business, we constantly study trends and factors affecting the industries we support and provide insights to issues affecting you.
The Clean Energy Council reports that the average school classroom uses 3800 kWh of electricity per year – about half that of an entire average household.
With only 27 per cent of schools having an Action Plan to reduce their energy consumption various State Governments have developed programs to support schools in the lowering of the power bills of schools.
In Victoria, the Government is piloting a program the Greener Government School Buildings Pilot Program
Amongst the initiatives contained in the program, The Victorian Government will stump up the funds for upgrades and schools will pay back the costs over a five-year period based on savings. After payback is complete, each school will keep half of the savings generated, making more funds available for other activities. Currently, 100 schools have been selected for the pilot
In NSW, the most ambitious and targeted program, targeting the cost and benefits of cooling schools is the Cooler Classrooms program aimed to deliver sustainable cooling, heating and fresh air ventilation systems to eligible classrooms and library spaces.
In Queensland, the Advancing Clean Energy Schools program has engaged, via a tender process, three contractors to carry out the state’s work. Unfortunately, schools are unable to be proactive in advocating their needs by applying for the program, so we could see a lot of Queensland school students swelter until the government comes around to their school.
The Northern Territory understandably is focussing on power generation as a sustainable option with their Rooftop Solar in Schools program.
As part of a significant boost for maintenance across Western Australian schools, the government will be removing old and inefficient heating and cooling systems.
At the time of writing, Tasmania does not have a specific school energy program in place.
Of course, it’s not just schools that are looking to reduce their power bills and become more energy-efficient, small to large businesses across the country have been looking for achievable options to reduce, specifically, their heating and cooling costs.
When it comes time to heat or cool large spaces – warehouses to a school gymnasium – refrigerated and even evaporative cooling become a highly expensive option to install and to run. The efficiency of these options is greatly improved when a High Volume Low Speed (HVLS) fan – the big fans sometimes seen in large hospitality and industrial environments – is incorporated into the cooling plan.
As a stand-alone option, HVLS fans are the most economical option for cooling medium to large areas. SkyBlade’s 1.8m Turbo Prop Fan cools an effective area of 18m or 262 m2, dropping the perceived temperature by 10ºC. SkyBlade’s Turbo-Prop range is also the quietest available 3X quieter than any other HVLS fan.
Ceiling fans as big as Texas! Only in America…….
It’s true these Ceiling Fans are big and hugely popular in America – not quite as big as Texas but they are made in the USA! Big on cooling and low in cost they’re becoming big news in Australia and New Zealand too.
To get you up to speed, here are a few facts about these big HVLS fans:
Known as HVLS fans, High Volume Low Speed, they move a seriously high volume of air and are the only affordable option when cooling large spaces, like warehouses, manufacturing areas, school halls and alike.
Circulation; High Volumes of air are circulated at Slow Speed, creating a gentle breeze and lowering the perceived temperature by up to 10°C over a wide space. Effectively turning a 35º day into a comfortable 25º.
Low Cost; HVLS fans have a low running cost, approximately 0.75c to $1.60 per kWh depending on the brand. That’s approximately $2 a day! Compare this to evaporative cooling at 0.90c and refrigerated air at $3.45 per kWh.
Efficient; Slow and steady, a 3.6m HVLS fan moves up to 3000 cubic meters per minute at a maximum speed of 88 rpm. This slow and steady rate creates a gentle breeze with low energy expenditure. It would take more than 10 pedestal fans to move this volume of air at a significantly higher running cost.
Big; HVLS fans are big! Ranging in size from 3.6 – 7.3m in diameter, however not all fans are created equal, the area cooled differs greatly using the same sized fan from different manufacturers, it is worth comparing the numbers. Designed for big areas warehouses, open-plan offices, indoor fitness, play centres, restaurants etc.
Quiet; A new generation of HVLS fans are not quite as big – 1.8 to 4.9m – and operate even quieter than their big brothers, thanks to the direct-drive motor. Designed specifically for smaller spaces – 262 to 1.8m2 –where sound minimisation is valued. Some brands are as quiet as a church mouse.
Works well with others; HVLS fans are great autonomously and love teamwork, in a team of other fans or other cooling systems. Working with existing cooling HVLS fans can lower energy cost by up to 30%, by operating air-con at 5-7°C higher temperatures and for fewer hours.
With the comparative testing results to back us, we know that SkyBlade the most efficient and cost-effective. Also, we have lived experience, our 900 m2 Australian warehouse and workshop is cooled using a single SkyBlade HVLS fan.
Made in the USA SkyBlade fans are simply better – Better Blades, Better Efficiency.
