The Light Sentry by Sonne Industries

Since no building has lighting automation as intuitive as a simple thermostat, EVERY building could benefit from the patented, transformational technology of the Light Sentry…the only lighting automation solution that offers a wireless, remote light sensor that communicates with a hub, that commands nodes to turn on, dim/brighten, and turn off. These commands are triggered by natural light, time or a combination of both. ...more »

App for mortgage lenders/borrowers to predict utility bills, local costs of EE/solar & effects upon total monthly expenses

Adding money for energy efficiency retrofits and solar installations (EERSIs) to the mortgage will overcome the primary behavioral challenge that a homeowner experiences when considering them post-purchase. A person borrowing $500,000 to purchase a home will think that adding $50,000 to reduce their bills is a much better deal than a homeowner who is asked to go from $0 to $50,000 to do the same. This web application ...more »

A software-centric approach to Building Automation to improve utilization of energy efficiency technology.

Building owners who can't afford legacy building automation systems (at a starting price of $10,000) currently have just one real solution: the programmable thermostat. They’re cheap but they quickly stop delivering efficiency and don’t provide data to facility and energy managers. Our approach is to turn the traditional building automation model on its head. Instead of costly hardware devices at the sites and specialist ...more »

Building Automation is too expensive for smaller commercial buildings. Can software help?

Even for a relatively simple building such as a box retail store, the cost of a basic automation system starts at more than $10,000. That's a lot of capital to invest for energy efficiency, and many building owners and operators simply decide to do without. Instead, they install a basic programmable thermostat for each rooftop HVAC unit. While that solves their construction cost problem, it creates an even greater one ...more »

App for mortgage lenders/borrowers to predict utility bills, local costs of EE/solar & effects upon total monthly expenses

One of the biggest hurdles for homeowners in performing deep energy efficiency retrofits or adding solar is a behavioral one, not technical or financial. It’s actually two problems. The first is that people tend to ignore the operational costs of an item, such as the utility bills of their home or fuel costs for their vehicle and focus solely on the sticker price or the monthly mortgage. This leads to non-realistic ...more »

DC Microgrid Controller for Tesla Powerwall and Other Battery Storage Systems

Problem: DC microgrids will play an important role in the sustainable electric infrastructure of the future but currently require a prohibitive amount of expertise and customization for substantial market penetration. Elon Musk announced on April 30th, 2015 that the Tesla Energy battery systems will be open-source (see attached link). I propose building on this open-source technology with a DC-DC converter/controller ...more »

Energy efficiency game?

People love games and, as silly as it is, a great game is a great motivation booster. We would collect huge amount of data and save energy if we could create a game where you can earn points/glory from energy efficiency actions at home or office. The amount of points earned per action should reflect the amount of energy saved. This would also provide a big picture to consumers that what is a big saving method and what ...more »

Window Awning Design for Optimum Shading

Show me a detailed design on how to shade my windows with awnings (or other fixtures) to maximize shade in the summer and minimize it in winter. That way I have to cool less in summer and heat less in winter.

 

The program should take into consideration the dimensions of the window, facing direction of the windows, the elevation, and latitude of the site to custom tailor the shading solution.
