Few people seem to realize that energy costs and use in buildings such as homes and apartments takes as much money if not more than in autos. I guess this is because natural gas and electricity meters tend to be hidden in dusty corners, with read-outs that are often indecipherable, so most people in the USA simply don't know when they are using a little or a lot of power.

Where I live in California, we are also facing a water shortage. So basically here are some of things I've done on one of my rental properties that might give others some ideas of whats possible to save energy, water and $$$ over the long run...
The above photo is an old apartment building in a "walkable" neighborhood that is in a pre-suburbia and pre-strip mall part of town. Basically my goal was to combine the "charm and allure" of 1920's restored Spanish architecture with a totally renovated and "pragmatic" open floor plan studio apartment that use to be a tiny and poorly laid out one bedroom unit.
Over a few year remodeling period the building was torn down to the studs and rebuilt "literally" from the ground up to be the most energy efficient and thus environmentally friendly apartment building in the area. One example of the the building being environmentally friendly is the choice of lighting, for example to save energy and illuminate the second floor hallway solar tubes were installed with the optional "Light Kit" which makes it possible to have an energy saving compact fluorescent hallway light at night and let in natural sunlight during the day, all in one fixture... I've calculated that with all the up grades, the building now uses I'd estimate somewhere in the neighborhood of 60% less energy over all, because it is now insulated, has dual pane windows, energy star appliances, and lighted throughout with compact fluorescent bulbs as compaired to when it was first acquired.
Unencumbered by the the thought process and somewhat immune to conventional social norms (since I religious ignore advertisements and useless social buzz) I opted to use the KISS design philosophy. Basically this means design selections were based on the idea things should be pragmatic, economical and durable. If ya look at the pictures you'll notice there are NO granite countertops and/or stainless steel kitchen appliances which I think of as faddish and didn't pass my cost/benefit analysis.
I'll bet in years to come these items (granite countertops and/or stainless steel kitchen appliances) will be associated and dated with subprime era kitchens, just like some variant of green color paint was used in many 60's and early 70's kitchens, and a 1950's era kitchen might be associated with red formica counter tops and steel cabinets.
Besides the faddish aspect, I consider granite countertops and stainless steel kitchen appliances akin to putting makeup on pig. Got that idea long ago and it was reinforced from watching various TV news segments about the number of foreclosed properties, ya know ones where a TV reporter was going thru a few properties with a real estate agent and in most places featured, they all had granite countertops and stainless steel kitchen appliances.
The money I could have spent on granite countertops and "upmarket" stainless steel appliances, I used instead to have custom build solid 3/4" plywood cabinets thru out in place of MDF in some parts, and I opted for old school "oil based paints" which from experience lasts much longer than water based finishes.
Since drought(s) will become more sever in the western part of the United States and seriously impact the San Diego area. When ya consider that landscaping accounts for about 50 percent if not more of residential water usage, and that in San Diego we have had below average rain fall for the last two years, I'm betting that water officials might be forced to restrict watering of lawns in the very near future!!!! So to address big problems of drought, environmental quality issues and help boost curb appeal, in place of unimaginative water wasteful turf landscaping, low-water use or xeriscaping principles along with edible landscaping ideas (by including citrus trees and strawberries plants) were used in the early California Mission inspired landscape design.
I've included some of the hard scape photos, to illustrate ideas I used to eliminate traditional lawn landscaping and I'm still going to add a few more landscaping elements (like planting some borage which is a herb that helps strawberries to thrive, and is a bee attractor) in the future.
FYI with the lawn taken out, and using various hardscaping that prevents run off, is used as lower on going maintenance costs, etc., I've estimated that the property uses 80% less water over all for landscaping when compared to a verdant, green lawn.
BTW tennant water use is way down because all the toilets are ultra low flush, and I installed the most water efficent front loading washer I could buy, so I'd estimate interior water use is down by over 70% when compared to using the 1920's toilet(s) and shower head(s), and the washing machine uses less than half the water of a top loader...
Now that I have the basic solid infrastructure done on this property, the only major thing for me to do on this property is add solar panels on the roof for net metering program. But right now as it stands, California laws are kinda wacked for net metering in a rental property, I'm more than willing and able to pay for solar cells, but there is more BS laws and regulations than I'm currently willing to deal with for net metering on a rental property.
I'm also encountering the same kind of BS building codes and laws in a historical district, which is the place I want to build a garage and put solar cells on the garage roof for my own home.
