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 »

CBE Occupant Feedback Toolkit

CBE’s Occupant Feedback Toolkit is a fast and cost-effective way of collecting and understanding occupant feedback. Originally developed by the Center for the Built Environment (CBE) at the University of California, Berkeley for research purposes, this resource has become widely adopted by manufacturers, building owners and design professionals to evaluate energy-efficient systems and technologies, and to understand how ...more »

Solar Doctor: A check engine light for your solar panels

Many residential solar owners have small, undetected maintenance problems that are leading to massive downtime for their solar panels. Using classification algorithms that detect different types of problems, Solar Doctor provides an automated alert to customers whenever there's a problem. We also provide a detailed description of the maintenance needed and offer a referral service. Further, we plan to use our collected ...more »

Arcadia Power Universal Utility API

Solar installers do not have an easy way of grabbing a customers past utility bills - but that data is crucial to understanding the viability of a rooftop solar array. Arcadia Power has technology to allow any solar installer an easy API call to grab data from over 100 utilities.

Homeowners with residential solar need a “check engine light” for their solar panels

Many homeowners with solar panels have no idea when minor maintenance issues have degraded or stopped the energy production from their installations. According to Pecan Street’s report on the need for a “check engine light for solar panels,” typical repairs require $25 and less than an hour of labor, but can often take systems offline for weeks or months. Even sophisticated homeowners who are actively monitoring their ...more »

Next Generation Solmetric

The solar industry needs to solve a next generation shading analysis and azimuth tool platform for the industry. Since Vivent bought the assets of Solmetric, there has been a great gap in the industry providing new sales agents with the tools necessary to conduct a complete shading analysis for a commercial and residential property. With the advent of powerful smart phones our industry needs to solve a new solution for ...more »

Mostly Crowd Sourced RECS and CBECS

The CBECS (commercial buildings energy consumption survey) and RECS (residential building energy consumption survey) datasets are widely used for national and regional benchmarking and decision making. These data sets are expensive to collect and as a result are updated infrequently. Given the number of commercial and residential building audits that occur in the US annually, is may be possible to crowd-source much of ...more »

Comparing measured and simulated building performance data

Building performance analysts lack software tools to track and compare measured utility and sub-meter data, particularly with respect to simulation results. This results in an open feedback loop in the industry, with many analysts having a poor understanding of how buildings actually perform with respect to their models. A low cost and flexible way for analysts to catalog and compare simulation results to actual performance ...more »

Solar Energy Data Dashboard

The world is moving towards a crucial climate change meeting in December 2015 (COP21). In June 2015, the International Energy Agency (IEA) issued a World Energy Special Report which notes that there are "no signs of a weakening appetite for renewables," with solar expansion especially strong in Asia. From a methodological perspective, however, emission reductions in the energy sector after 2020 (described in the 450 Scenario) ...more »

Data for Validation of Retrofit Audit Simulation Tools

Many building energy simulation tools exist to help determine the most cost effective energy retrofit packages for existing buildings. Evidence indicates that these tools frequently over-predict the base building energy usage and the energy savings from the retrofits. A large database of pre- and post-retrofit energy use data is needed to validate and improve the models and associated model calibration methods. Such a ...more »
