The Power of Information: Unleashing Energy Consumption Data

community_mapEncouraging energy efficiency among residents and businesses is hard work, not least because of the absence of accessible and easily understandable information about energy consumption. Most people don’t understand everything on their energy bills, don’t know if they’re using more energy than they should, and have no way to compare their energy use to that of their neighbors. This information is often guarded closely by utilities, presenting energy efficiency advocates with a formidable barrier.

In her thesis, Alexis Howland (MCP ’13) sketches the possibilities afforded by better energy consumption data. She surveyed efforts across the country to share energy efficiency data. Alexis focuses on incorporating these data into mapping applications—which could lay bare the differences in energy consumption among homes and add valuable information to the housing market. These efforts could be combined to allow no-touch energy assessments that offer actionable suggestions for homeowners who want to improve their energy efficiency.

In a survey of five previous attempts at energy mapping, Alexis notes a common theme: the developer’s inability to access or make public energy consumption data at the household level. This, Alexis explains, is due to privacy concerns that have so far prevented such data from being used to its full potential.

Alexis explores ways of unleashing these data. Several cities—including Boston—have recently passed ordinances that require the disclosure of energy consumption data, and the federal government has offered a framework for voluntary energy data disclosure through the Green Button Initiative. While these efforts must overcome serious privacy concerns, they have the potential to make public vital information about the way people and buildings nationwide use energy. Read more about Alexis’ survey of the opportunities for and barriers to energy mapping projects in her thesis.

Go Local! Energy Costs and Environmental Benefits of Microgrids

As our infrastructure ages, demand for power increases and climate disasters loom. Cities are facing rising costs and security risks around their energy supply, all while seeking ways to decrease their carbon impact. Unfortunately, the existing regime for supplying and distributing energy in the United States is a regional enterprise, with the majority of energy produced far from the main areas of demand. In order to take control of their energy consumption, many cities are attempting to establish localized energy infrastructure. By producing energy at the location of its consumption, cities can significantly lower the cost of energy, increase the use of low-carbon energy technologies, and improve energy reliability and security.

In 2012, Genevieve Sherman (MCP ’12) evaluated two U.S. cities’ attempts to create a microgrid and a district energy system in the heart of their downtown commercial districts. Since these areas are comprised of multiple stakeholders, she assessed the organizational structure they developed in order to delegate core roles in implementing new infrastructure: ownership, management, operations, rate setting and financing. Genevieve argues that in order to successfully implement these technologies, commercial district organizations must pursue a carefully crafted engagement, educational, and fact-finding process that will prepare all stakeholders to interconnect into a shared energy system.

A Better Way to “LEED” in Energy Ratings

Energy efficiency measures in residential buildings are some of the lowest-cost means of cutting energy use and greenhouse gas emissions. According to experts, by 2020, residential buildings will consume 20% of U.S. total energy use – more than the commercial sector – and will contribute 1,350 million tons of carbon dioxide equivalent (CO2e) to the U.S.’s annual carbon emissions. Still, despite the fact that building insulation, lighting upgrades, and efficient water heating all have a positive net present value (NPV) per ton of greenhouse gases abated, very few home energy upgrades and retrofits are taking place, as compared with the volume of inefficient housing that remains in the market.

In 2012, Nikhil Nadkarni (MCP ’12) studied four U.S. cities’ attempts to promote energy efficiency through building energy ratings and labeling. He found significant variety in the way these rating systems were utilized. Nikhil analyzes the weaknesses in the current approaches and argues for a new model, using a web-based database that promotes transparency and improved accessibility for consumers and assessors.

Using Community Meetings to Recruit Households into Home Energy Upgrades

Around 65 million homes in the USA could benefit from comprehensive upgrades to save energy. Serving these homes can decrease emissions, create jobs, stimulate local economies, and improve the health of indoor environments. However, marketing upgrades has proven difficult; households typically do not understand energy saving opportunities, are hesitant to take on financing to realize small net energy savings, and distrust programs and contractors.

Faced with these challenges, many upgrade program administrators have experimented with marketing upgrades via different community networks, such as neighborhood associations, churches, civil society organizations, common employers, or informal acquaintances. In his Masters thesis, Brendan McEwen (MCP 2012) explores the community based outreach strategies that can realize greater participation in upgrade programs. Brendan’s research suggests that hosting meetings that bring together a group of recruits, past participants, upgrade contractors, and program personnel, is an effective marketing mechanism, capable of providing a rich introduction to the concept of upgrades and fostering a sort of “peer pressure” to sign on for a home energy assessment. Brendan suggests program administrators should tap many different community networks, to recruit households into such meetings. More strategies and lessons from the field can be found in Brendan’s thesis.

Do Renters Miss Out on the Benefits of Energy Efficiency?

Increasing energy efficiency is a popular notion. It garners support from environmentalists to economists to every person who pays a utility bill. But when it comes to retrofits, more homeowners are benefiting from energy efficiency than renters. Patrick Coleman (MCP 2011) thinks this a problem worth looking into.

To do this, Patrick analyzed local city ordinances that aim to enhance the energy efficiency of rental properties in California, Wisconsin, Vermont, and Texas. He found that the barriers to energy efficiency improvements are significant, but the potential in rental housing looms large. The lack of information, fragmentation of housing and energy markets, and misaligned incentives, however, challenge retrofits. Also, the diversity of property owners, from individuals to multinational corporations, presents policymakers and program administrators with varied motivations and interests and makes coordination of resources extremely difficult.

Despite this, Coleman found that well-designed ordinances can 1) establish a minimum standard of energy efficiency in rental properties, 2) enable energy efficiency program administrators to focus their attention beyond basic measures to deeper retrofits, and 3) facilitate the valuation of energy efficiency in housing markets.

Coleman recommends partnerships between local governments, community-based organizations, and utility companies to motivate better energy efficiency in rental units. You can read more by checking out Patrick’s thesis.
