Turning things off when they are not needed.
DDC controls with better algorithms and controlling more building systems.
More efficient pumps, fans, motors, etc.equipment.
More use of variable flow pumps and fans.
Increased insulation.
Better performing windows.
Heat recovery between outside air intake and exhaust.
Gas fired heating equipment that use low flue temperatures to capture the heat of condensation from water vapor in the flue gases.
Lower wattage lighting.
Architects paying attention to the orientation of the building and shading of windows to maximize heat gain in the winter and minimize it in the summer.
etc.
Problem is, most of these require additional upfront costs and businesses are often more worried about being in business a year from now than they are about how much they'll save over 7 years.
Combine that with the extra effort it takes to design with yet another factor (energy) to consider, and there's a lot of inertia to keep things as they have been. Fortunately, many of these are becoming mainstream off-the-shelf items now.
Don't worry, if the Saudis pump the price of oil below $70/bbl, all new fracking will stop and the cost of using natural gas will rise well above coal within a year or two.
I work in the HVAC field, and believe me, there is plenty that can be done relatively cheaply to reduce energy use. It is starting to happen now, but it could have been done 30 years ago if it weren't for the inertia of the construction industry.
Sounds like a lot of ordinary construction projects I've been involved in. For example, a large, 3-story anchor store in a shopping mall decided to move the escalator after the structure had been erected. And a famous business machine company suddenly realized that they couldn't put their remote backup service in the high rise office they were remodeling because the reception of the satellite dish on the roof would be blocked by their own building next door. And yes, sometimes regulations are involved, such as changes to completed work because of building inspectors' rulings.
People who only care about the cost don't rent offices in skyscrapers . . .
True, but people that care about having a large pool of workers to hire and close proximity to as many clients as possible tend to want offices downtown. Downtown is full of skyscrapers in order to house as many a commuters as possible during working hours. So many people rent a space with a "very expensive view" even though they don't care about it as a status symbol.
It is not just cost, we don't have the technical ability to make good enough robots that clean as well as humans.
I'm guessing that we would have the technical ability, we just haven't put enough time and money into developing it, since there is no great payoff at the end.
Being a business or not might not have much impact on liability for a particular incident, but the insurance actuaries know that business insurance is riskier.
You are not correct.
My home insurance will cover accidents that visitors have on my property, but will not cover customers if I'm using it as a place of business - that'd be a whole different level of risk for the insurance company.
Similarly, insuring a taxi driver is a much larger risk for an insurance company than insuring a private driver, even for the same number of miles.
Why should I, as a private driver, pay for the same insurance that covers the larger risks of taxi drivers?
This eliminates the gap, which starts vortices (causing noise and other issues)
Those air gaps are essential to keeping the air flow attached to the wing surfaces at the large angles of attack required at landing and takeoff speeds.
I doubt that this could allow the large angles of attack provided by the flaps that deploy with multiple separated segments that are used on most commercial aircraft.
One thing it will cost is the deal that no new construction will happen at the lakefront. It is supposed to be park land open to the public. There is almost sure to be a lawsuit to prevent it being built east of Lake Shore Drive.
Montgomery Ward was instrumental in creating that precedent, which has, nevertheless, been violated several times.
A newly released email shows that White House officials sought to shape the way Susan E. Rice, then the ambassador to the United Nations, discussed the Middle East chaos that was the context for the attack on the American diplomatic mission in Benghazi, Libya, in 2012.
That's not a scandal, that's just a (partial) description of an ambassaor's job.
The whole problem is that you may have been reading an article written by a blogger who made some rather idiotic assumptions about the precision of the sine function.
The only incorrect assumption the blogger made was that Intel's documentation stating the precision of their implementation of the sine function was correct.
But even then, it does not really make sense to discuss the precision near special values such as PI/2 because the precision of your input data will be unrealiable around that number.
In the subject case, though, the input was precise because it was a purely mathematical operation to illustrate a technique for converging towards the exact value of Pi. The misleading documentation led the author to believe that the technique should work using a compiler that uses Intel's FSIN(), but doesn't. He also found out that some compilers avoid the issue.
I was just about to say the same. Also, most of the best Bugs Bunny 'toons and other Looney Tunes were originally movie shorts made to play in the theater.

TFA calls gallium rare, too, which is not exactly true, at least not compared to most so-called precious metals.

I think she should be sued for copyright infringement.
The first time I encountered a computer virus it splashed a big marijuana leaf across the screen to let us know it was compromised. Just saying.
It might be funny, but it's not true
I don't know where Karmashock lives, but I live in northern Illinois, USA, where we get over half of our electricity fom nukes.

You're belief is incorrect, for younger kids, anyway.
