The New Edible Landscape

While the edible garden may seem rather unconventional today, 65 years ago, when the nation was at war, edible landscapes were the norm. In a huge effort, the government encouraged individuals to plant Victory Gardens in their own yards or in community settings, to help fill in gaps in the food supply. It was seen as patriotic to provide food for oneself or for one’s neighbors. Continue reading »

Dwell Design Conference – Greywater

In June, I made a presentation at the Dwell Design Conference in Los Angeles entitled “Luxury Eco-Homes go Net Zero Water for the California Landscape”. The following post outlines the key points of my talk that illustrate how to achieve Net Zero landscape design.

Greywater and rainwater systems are a sustainable, cost effective ways to irrigate your landscape and are key to achieving net zero water usage. To achieve Net Zero, the landscape design must be done intelligently, with the supply anticipated so that the available water will inform the demand that is generated. Similar to an income which determines allowed expenses, the landscape design may need to be adjusted in order to respond to the available water by adjusting the specified irrigation system and plant choices.

On Demand Retrofit Hot Water Recirculation Systems

For many older homes built before the advent of hot water recirculation systems, lag times while we wait for hot water to come out of a faucet is something many of us deal with in our homes every day.  This not only wastes our time, but it also wastes energy and a lot of water, 6+ gallons of water a day on average per household.  This equals 700M gallons a day, nationwide, dumped down the drain because the water was not hot enough for its application.

Rainwater Diversion in the City of San Francisco

HOW DO YOU MAKE 1,800 GALLONS OF RAINWATER DISAPPEAR?

With a typical roof shedding hundreds of gallons of water in a major rainstorm, an important and potentially expensive issue arises in many San Francisco remodels: where does it all go?

Rainwater diversion can be a cost-effective and sustainable solution. In this post, we will walk you through the definition of rainwater diversion, its benefits, and the permitting issues and methods necessary for execution.

Passive Air Cooling – It’s not Just for the Birds

In 2007, Matarozzi Pelsinger Builders worked out of a loft-like industrial space in the Mission that lacked sufficient air flow on the handful of warm San Francisco days.  During those San Francisco “heat waves,” we had to haul out 6’ tall industrial fans in a feeble attempt to move the air. With the fans howling, it felt like working in an old airplane hangar with prop planes readying to taxi out to the runway. Continue reading »

Water Heater Basics: Gas or Electric?

Photo by Paul Dyer Photography

Most households in the U.S. use natural gas to heat water. Other fuel types include electricity, propane, and heating oil. A typical gas storage water heater has an Energy Factor (efficiency rating) of about 0.6, while a typical electric storage water heater will be rated about 0.9. Based on these Energy Factors it would seem an electric water heater uses less energy.  Actually the opposite is true, here’s why: Continue reading »
