Steam heating system retrofit in multifamily houses into “vacuum boost” steam heating.

Problem scale. Significant, untapped opportunities exist to improve the energy efficiency of the nation’s multifamily housing stock, which accounts annually for more than 100 million tons of carbon emissions and approximately $22 billion in energy expenditures [1]. Most multifamily rental properties were constructed before modern building energy codes were adopted, and existing utility incentive and rebate programs often overlook the…

Gas vs Induction Cooking Energy Comparison

Comparison Between LP Gas Range and Induction Burner

Energy Burden by Income

It’s no surprise that household energy expenditures put a considerable burden on low- to middle-income families, and a study correlated this impact by measuring the correlation between income and morbidity due to extreme heat or cold.

 

The Centers for Disease Control and Protection published the results of the study that analyzed data between 2006 and 2010. The study analyzed morbidity rates due simply to extreme temperatures. They found that counties throughout the U.S. that…

My Apartment in Tokyo

Every time I visit Japan I learn something new, and my most recent trip was no exception. This time I stayed in an apartment, which exposed me to several new energy-related devices. First, what’s this gadget attached to the wall? (See photo below.)

Reading the Japanese isn’t terribly informative, because the label just says it’s a “peak alarm unit.” The apartment’s owner pays the…

Whole House Fan Thermostat



News for 2016! I have invented a thermostat for whole house fans that can be used on any installed fan. As you know, whole house fans should not be automatically started because there is no way to know if return air is available in the form of, usually, open windows. So my thermostat does not start working until the fan is turned on by the homeowner. Then it senses the home temperature and automatically turns the fan off when the temperature falls to the set point desired. More info at…

Relay Network Targets Multifamily Housing Upgrades Nationwide

Affordable apartment buildings are home to more than 10 million American households, making them a backbone of U.S. housing stock. They also waste a lot of energy.

In fact, energy efficiency measures are far less likely to be found in multifamily buildings than any other type of housing, according to a 2011 report by the U.S. Department of Housing and Urban Development.

Several hurdles have stalled upgrades: building owners lack access to capital, utility-run efficiency…

What is DWHR?

What is Drain Water Heat Recovery?

Answer this...when you take a hot shower, what happens once that HOT water goes down the drain and how do I reuse the energy? That is Drain Water Heat Recovery!

A "DWHR" can capture waste heat energy and be used to heat NEW incoming water, saving money & energy, as well as the life of your hot water tank. It also works well with Geothermal, Solar and Tankless (on demand) Water Heaters.

In residential and commercial applications, all the…
