A bright idea has led the Letterkenny Shopping Centre to win a Green Jersey Award from Rayal Energy.The popular shopping centre, which is part of the Harcourt Shopping Centre group, has earned praise for making the switch to LED lighting. The results have been immediate and extremely cost effective.Letterkenny Shopping Centre is committed to being as energy efficient as possible and the conversion to LED has vastly reduced the centre’s energy consumption. Ed McCulloch, the property manager who received the award at the recent FM show in Dublin’s RDS on behalf of Letterkenny SC and the other Harcourt Centres said: “Harcourt Developments are proud to receive the Green Jersey award from Rayal Energy for saving 642,401 kg of CO2 by making the big switch to LED. “All six Shopping Centre’s in the Harcourt Group have now completed LED lighting upgrades which use significantly less energy than fluorescent fixtures, while increasing lumen output to make our Centre’s brighter. On average the upgrades have provided energy savings of approx. 40%, so great for the planet and our tenants,” Mr McCulloch said.Tom Hefferon (CEO) Rayal Energy, Ed McCulloch (Senior Property Management Surveyor) Harcourt Developments, Michelle Shirley (Sales & Operations Director) Rayal Energy.Letterkenny Shopping Centre awarded for making the big switch was last modified: April 5th, 2019 by Rachel McLaughlinShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:harcourt development groupled lightingLetterkenny Shopping Centre.rayal energy
Brattleboro, Vermont is fortunate to have a long history with solar water heating. When I moved to the area in 1980, the company Solar Applications had been installing solar hot water systems for five years, and a spin-off company, Solar Alternatives, was manufacturing quality flat-plate solar collectors—many of which are still in use in the area. While Solar Alternatives closed down in the 1980s with falling energy prices and the end of solar tax credits, Solar Applications, has continued to install and service solar water heating systems for more than thirty years.Frenchman Alain Ratteau, who founded Solar Applications in 1975, sold his company this year to Andy Cay, and it has been renamed Integrated Solar Applications. When interest in solar waned in the mid-80s, my friend Alain shifted most of his focus to oil or gas space heating (specializing in the more sophisticated systems), but I was always impressed that he maintained the company name Solar Applications and maintained a deep commitment to renewables. Alain works with the new company and is helping to establish it as a premier provider of not just solar water heating systems, but also solar space-heating, solar-electric, micro-hydro, wind, and biomass. Visit the company on Spring Tree Road (past the Marina Restaurant).Most solar water heating systems consist of one or more flat-plate collectors mounted on a roof or separate rack through which potable water or another heat-transfer fluid is pumped. This fluid circulates to a storage tank where the solar-heated fluid passes through a heat exchanger to heat water in the tank. With “closed-loop” systems, the heat-transfer fluid—usually a mix of water and nontoxic propylene glycol antifreeze—remains in the collector all the time. In other systems, referred to as “drainback systems,” plain water is used in the collector, and when the collector gets too cold, the water drains back into a small tank in the house.Other systems operate passively by “thermosiphoning” (the principle that heated water rises naturally). With this approach, more common in warmer climates, potable water in the collector naturally circulates into a storage tank located above the collector.A fairly recent option with some solar water heaters is a solar-electric (photovoltaic) panel to power the circulation pump. In this case, the PV panel serves as both the pump’s energy source and the controller. When the sun is shining and the PV panel is generating electricity, the pump operates and water is heated; when there isn’t enough sunlight to power the circulator pump, the solar water heater shuts down—it’s a simple control system.No matter what type of solar water heating system is used, in our climate it is generally used as a “preheater” for a conventional water heater—which can be either a storage-type water heater or an on-demand (tankless) water heater. The standard water heater, which could be electric or gas-fired, boosts the water temperature as needed.Don’t expect a solar water heater to provide all your hot water. A well-designed and properly sized system in our climate may provide all of the summertime hot water, but it is likely to provide less than half of what you need during the winter months. Some homeowners combine solar water heating with a heat exchanger in a wood stove—so that they’re heating their water primarily with renewable energy sources year-round.To maximize the percent of hot water your family can obtain from the sun, it’s important to conserve hot water use: install low-flow showerheads and faucet aerators; insulate your hot-water pipes; buy a top-efficiency dishwasher and only wash full loads; and consider washing clothes in cold water.Installers of solar hot water systems in the area include Integrated Solar Applications in Brattleboro (257-7493), Gary MacArthur in Marlboro (257-7026), John Kondos of Home-Efficiency Resources in Spofford (603-363-4505), Green Energy Options in Keene (603-358-3444), and the Greenfield Solar Store (413-772-3122).

Tina HouseAPTN NewsFor over 40 years, activists Bernie Williams and Gladys Radek have been fighting for justice for missing and murdered Indigenous women and girls.But now they are mourning news that the national inquiry tasked with examining the missing and murdered will only be granted a six-month extension.“There is a lot of things that are happening to our women today and our women are still disappearing, our girls are still being murdered and our men and boys are going missing and still being murdered,” said Radek, while standing beside a downtown Vancouver monument honouring the missing and murdered.“Nobody is doing a damn thing about it and they wanna pull the plug?”Tina House reports.
