In California, like other states, there are Energy Conservation Standards. We go to great lengths to provide buildings that are energy efficient (envelope, HVAC, lighting, etc).
Yet, as I go through retail stores and some restaurants, most, if not all, leave their front entry doors wide open to the outside. So when temperatures are in the 90 and 100's outside, the HVAC is on full blast and the nice cool air is escaping through the entry door(s) to the outside. Basically, you are helping cool the outside of the building. Talk about putting a great demand load on the HVAC and energy use for the space that we were trying to conserve in the first place!!!
So why design for energy efficiency if we are going to do that??? It's an oxymoron! Why worry about designing energy efficient buildings when they are leaving their exterior entry doors wide open (talk about massive exfiltration problem)!!!! Does not make sense at all
I know the reason why they leave the doors open and nice cool air blowing..it's very inviting for customers trying to escape the heat outside and makes sense to retailers..they will come in and this may be translates into sales $$$.
BUT from energy conservation point of view...what a hypocrisy! I say forget designing and mandating energy effeciency if that is the case.
What say you?
