Couple lives green in their Key Largo dream

South-facing small windows and Bahama shutters, light paint and a white roof offer clues to the character of this house within a hammock: It is a ''green'' home that proudly wears a photovoltaic system and thermal water heater on its roof and envelopes a 7,500-gallon cistern within its walls.

Kendall house is a model of efficiency

Albert Harum-Alvarez, a software designer and consultant, grew up in Kendall and has spent years planning his home among the trees. Now under construction, it will catch the southeast breezes, use a geothermal pump for optional air conditioning, and employ a composting toilet system. Harum-Alvarez believes it's the greenest home in Miami-Dade County.

How to build a green home

If you are building a home, there are ways to make it energy-efficient: Orient it so the long axis runs east and west. Limit west-facing windows.

CERTIFICATION

Interest in going green is growing

Standards now qualify homes, commercial buildings and neighborhoods to be green. Certification is gaining in popularity.

Habitat homes designed with efficiency in mind

Pompano Beach houses will reduce water use and energy costs.

Two '60s houses are models for green living

This is one in a series about living green. Next week, we explore contemporary green homes. Forty years ago, Gwladys and Eugene Scott combined their lives and families and set out to design their dream house: a Japanese-inspired home in a South Florida hammock.

How to retrofit older homes

How can you retrofit a concrete block house with few windows to be more resource-conserving? ''It may not be practical to add a porch, but it might be practical to add shade trees on the south and west sides,'' suggests Janet McIlvane with the Florida Solar Energy Center in Cocoa.

Air conditioning changed everything

Half a century made all the difference. We went from designing with the climate to defensively shutting it out while shutting ourselves in, and today we are paying the energy price.

Tips for living without air

Living without air conditioning has its challenges, and with experience, Joyce Gann has learned how to do it.

Go native: Florida friendly landscapes thrive with less water

Wise use of native plants can go a long way toward reducing outdoor water use while celebrating the place you call home.

APPLIANCES

Switch to water-friendly appliances is on tap

How many times a day do you flush a toilet? How long are your showers? How many loads of laundry do you wash a week?

Saving resources as your clothes spin at high speed

A new washing machine will appear in stores this summer that spins clothes so fast (1,200 revolutions per minute) they come out almost dry.

Let us count the numerous ways that toilets can flush

How lush does it flush? The newest high-efficiency toilets use only 1.28 gallons of water. Not lush. And that's the point. While 1.6 gallons per flush still is the standard, the new versions use 20 percent less water. The Environmental Protection Agency's voluntary WaterSense program, begun in 2006, will certify that products use less water.
