Water-conserving faucets were installed at both sinks, and a designated tap provides filtered water so the family can avoid drinking bottled water. (Empty plastic water bottles are a growing litter and environmental issue.) 

Energy-efficient compact fluorescent lamps were used in the recessed ceiling fixtures. Because most fluorescent lights are not dimmable, David put the recessed fixtures on two separate switches or lines. That way, when less light is needed, only half of the recessed lights—interspersed throughout the room—are turned on. (Lighting manufacturers are developing dimmable fluorescent lights for residential use, but traditionally dimming fluorescent bulbs requires adding expensive controls, and is mostly done in commercial buildings.)

Countertop task lighting in the kitchen is provided by halogen lights, which can be dimmed.

For the family dining area, David designed decorative pendants made of recycled materials. Circular fluorescent tube lamps are housed in two translucent boxes fashioned from resin of 40 percent post-industrial recycled content. David designs eco-minded light fixtures for his business, Fire and Water.

Existing skylights were repaired and new energy-efficient windows installed. Air quality was also improved with a new central air- conditioning system equipped with a HEPA (high-efficiency particulate arresting) filter.
