I have repeatedly blogged about my concerns with the current and future energy codes because the codes are not keeping up with technology for lighting efficiency (see my previous blog posts titled “Why are Lighting Energy Standards Decreasing” and “More Issues with the Energy Code – Lighting is Running Rampant”). The graphs below, developed by our friends at Optimal Energy, show some comparisons of Department of Energy (DOE) predicted efficacies for lighting technologies and the efficacy needed to meet code for some common space types.
I recently had the privilege to travel to Colombia with Engineers Without Borders to assess the needs and resources for an irrigation project for family farms. Colombia is very well suited for coffee and sugar cane, but the dry season is too harsh for more sensitive plants like basil, lettuce, spinach, and peppers. For this, farmers need drip irrigation, water catchment, water reservoir, and water diversion. Our group’s goal is to develop an affordable, sustainable, and replicable design as a pilot project for ten farmers in central Colombia. We are working with Food 4 Farmers, an international non-governmental organization (NGO), Nueva Realidad, a Bogota based NGO, and Nuevo Futuro, the local coffee cooperative. We knew what our goal was before we started, but we had no idea what to expect from the trip. Here are our impressions of the country with which our team returned.
While this is off the topic of energy efficiency and optimized building functionality, it’s relevant to sustainability, specifically the long-term health of businesses and the people they employ. The United States’ health care system is in crisis. As a nation, we spend over twice the amount on health care than other developed countries, but rank last in terms of health care outcomes, such as equity, efficiency, and mortality rates (see: How Bad is U.S. Health Care?). As the cost of health care rises, the financial hardship of staying well not only burdens those who need help the most – the sick and the poor – but also those businesses committed to providing health care to their employees.
According to various studies, the United States is beating its energy reduction and renewable energy production goals beyond any federal predications. Total energy consumption in 2016 was 17% lower than expected, wind power production was 79% higher, and solar production was 383% higher than the United States Department of Energy predicted in a February 2007 report, as stated in the October 5, 2017 Statista Portal. In addition, a 2017 U.S. Energy and Employment Report finds that 45% of the 1.9 million workers in the Electric Power Generation and Fuels technologies are in the low-carbon emission generation technologies (renewables, nuclear, and advanced/low emission natural gas).
I’m writing this blog from the floor of the Andover Public Library in Andover, MA. After a major windstorm, power is out all over New England and people are scurrying for the few available power outlets and sources of internet.
Earlier this month, the New England chapter of the American Institute of Architects’ (AIA) Committee on the Environment held their annual leadership summit in Burlington, Vermont. As the keynote speaker, Clark Brockman – principal at SERA Architects and a leader in his field – delivered a presentation on district scale solutions for net zero energy and water in communities.
Following the withdrawal of the United States from the Paris Climate Agreement and the abdication of responsibility at the federal level to address climate change, the action now moves to states, municipalities, businesses and individuals. Fortunately, there are a lot of exciting things happening right now in these arenas, which could go a long way toward filling the current leadership vacuum. This post will survey some of the efforts underway, with a focus on initiatives aimed at improving energy efficiency in buildings.
I appreciate NASA’s Global Climate Change website as a resource for scientific evidence of the existence of human-made climate change (https://climate.nasa.gov/evidence/). The facts are simple, such as the rate of global sea level rise during the last two decades being nearly double that of the last century. Of course, the most telling fact is that the planet's average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the beginning of global temperature record keeping (around 1890). Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001. Essentially every year is warmer than the year before and is the warmest year on record. That is, until the next year.
On Samsø Island in Denmark, Søren Hermansen led a community of 3,724 to achieve their zero-carbon goals in ten years. Today, every person on the island has a negative carbon footprint. What can cities in Vermont learn from Danish methodologies of stakeholder engagement so they can reach their carbon reduction goals?
When people hear that scientists predict only a 2-4 degree rise in global temperatures due to global warming, they often shrug. That doesn’t sound too bad. If a warm summer day is 85 degrees instead of 82, what’s the big deal? But a 2-4 degree rise in temperatures means much more than that, and it’s important to know what it means if we’re to understand why climate scientists call for an immediate reduction in carbon emissions world-wide.
