All Mod (Air) Cons

Posted by andrew on August 5, 2010

As the temperatures took a real dive yesterday, thanks to the rain, air-conditioning became unnecessary (even if lurking were some truly bizarre, exaggerated ideas as to yesterday’s temperature, but ’tis ever thus). By coincidence though, there was a report in “Ultima Hora” about the optimum setting for air-con units during the summer. A couple of days ago, the government’s energy director-general kicked off a campaign for different aspects of energy-saving. One of them is that the temperature should be 26 degrees. For every degree lower, energy consumption rises by eight per cent, so he says. Given the cost of electricity, his advice is probably worth heeding. But those of you who have been paying attention will recall a piece on 8 July (“Rattle and Hum”) about air-con. In that, I mentioned the plan to establish temperatures in bars and restaurants etc (“a mad proposal”). Interior temperatures would not be lower than 26, which is exactly what the director-general is now recommending.

Recommendation is one thing. Getting people to do anything about it quite another. But there is more than just recommendation. In the article, it says that a temperature of 26 degrees is “obligatory for public places”. Is it really?

A while ago, there was another press report about temperatures being too high in public buildings during the colder part of the year. One of these buildings was the island’s environment ministry. Heating too high or air-con too low. It’s the same waste of energy, and guess who’s wasting it? One should perhaps applaud the town hall of Andratx which has banned air-con. Sales of fans must have soared, and not necessarily electric ones.

It’s the definition of “public places” that is confusing. The smoking ban will apply to just these public places, as in bars and restaurants. So has an obligatory level of air-con temperature been applied to these and no one has been told. If it hasn’t, then one can guess that it probably will be. It might sound like a mad proposal, but the government is serious as to its energy policy.

There are places one goes into which are near freezing. Supermarkets, for example. Are these public places? The 26 degree advice (78/79 Fahrenheit) is widely accepted as being energy-efficient, and not just in Spain, but when there are higher air temperatures, the temptation is to turn the air-con down lower. It is for this reason, one presumes, that there is the other proposal regarding keeping doors to bars and restaurants closed.

If the current definition of public places is only public sector, then one can expect that it will be widened, and that recommendation will turn into enforcement. Bars and restaurants have been warned.

By the way, as far as weather is concerned, and there will be those who are concerned given the rain, this is the link to the Spanish Met Office for Alcúdia. You can go to http://www.aemet.es/es/-m:b/eltiempo/prediccion/localidades/alcudia-07030. It shows (or did at 21:00 yesterday) 30 degrees maximum by Friday with a five per cent chance of rain and the same for a few days after. For Pollensa, you can click on “localidades” and get to the forecast for there which, you will not be surprised to learn, is the same. On the HOT! AlcudiaPollensa Facebook, I posted the links for the local weather stations, and these give current weather information.

Rattle And Hum: Air-conditioning

Posted by andrew on July 8, 2010

Could you live without air-conditioning in the heat of a Mallorcan summer? Many make do without it. Like me. I rarely even put it on in the car. To some extent, it has to do with home design and situation, especially the interaction of the position of the sun during the day and any shielding, such as an intervening terrace roof. But even without the influence of direct sunlight, the temperatures are high.

Air-con is hardly cheap to run. It can also be expensive to install. A restaurant owner recently explained to me that a new system had set him back 50,000 euros. That’s a lot of lunches and dinners to be sold. Home units may not come to anything like this amount, but neither are they inexpensive.

Somewhere still lurking in the Wacky Department of the Spanish Government is a proposal for temperatures in bars and restaurants, one that would also insist on doors being closed and operated automatically, in order to limit changes to temperatures inside. The proposal was that interior temperatures would not be lower than 26 degrees (79 Fahrenheit) during the summer months. It was and is a mad proposal, but the thinking behind it was to conserve energy and to be environmentally friendly. It is still possible that it might actually be passed into law, at a stroke rendering air-con units more or less redundant. That it seems to have been put on the back burner, so to speak, probably has more to do with the politics of the smoking ban than any desire to save the planet.

Air-con has become pretty much de rigueur for bars and for hotels. Its presence forms part of the promotional mix. “We have air-conditioning.” But not all hotels do, especially the older stock. I am led to believe that Bellevue – all 1400 plus apartments of it – could finally be kitted out with air-con. The new owners have an air-con company in their portfolio. It would still represent a massive investment, even given some favourable inter-company transfer pricing, to say nothing of the need for a dedicated system of power generation and also the charges to the guests.

In 2003, the summer of outrageous heat, the power system in Mallorca gave up one day in August. The outage lasted for up to eleven or twelve hours in parts of the island. We are told that there is plenty of capacity now to meet demand, but just think about the level of supply – for all those hotels, restaurants, shops, homes and everything else. One can argue that demand for electricity is very much lower in winter, thanks to all those cold hotels being closed. Open them all up and the gross demand for energy on the island would be significantly greater than it currently is. Perhaps this is a good reason for there only being limited winter tourism.

Air-con units and the demand for electricity have now moved into overdrive if not overload, but the temperatures are still not particularly excessive, despite an average two-degree above normal for the start of July. The fear is that, somewhere down the line, temperatures will become excessive and normal. The demand would be colossal.

The good news is that the island’s power stations now have capacity, at least for current needs and a foreseeable future not sent haywire through climate change.  The new one in Palma, that was opened in 2006, should be capable of handling estimated increases in demand of up to 6% per year. The growth in demand had actually gone up by a third in the five years before the plant started operating. The arrival of natural gas should be an advantage, albeit not to the plant in Alcúdia, which is coal-fired and which remains a bone of contention for environmentalists – Greenpeace have, in the past, tried to stop the shipping of coal to Mallorca.

The answer to the original question is almost certainly no. No you couldn’t live without air-conditioning, and it may be that air-con becomes a matter of life or death, if we are to believe the predictions as to temperature rise. For now though, you can be sure that there will not be a collapse of the power system and that the air-con unit can rattle and hum away, racking up the electricity bill. There again, you could always keep the windows open. Or could you? Some would argue that an open window just lets in warm air, while at night in fly the mosquitoes. And then there is always that mad proposal. To air-con or not to air-con? Who’d be one who wants to save the planet?
