Salmaan Craig to discuss thermoregulation of buildings at Le Lab ArtScience Talks

On Wednesday, January 11, Le Laboratoire Cambridge will host CGBC Research Associate Salmaan Craig, lecturer in materials science and energy at the Harvard Graduate School of Design, who will lead a talk on entitled “The Thermal Resonance of Massive Buildings.” Craig, a designer who specializes in materials design and building physics, conducts research on new types of ‘architecture-d materials’ for the thermoregulation of future buildings. This lecture is part of  the ArtsScience series, where architects, biologists, engineers, musicians and others talk about “creativity and culture at the edges of art, science and design.”

CGBC launches online forecasting tool to analyze building energy consumption

CGBC researchers have launched a new web app that uses statistical modeling and historical data to help predict building energy consumption. The Gaussian Processes Forecasting Tool allows users to upload data, configure features, train/validate a model and make predictions. For a deeper analysis, the app helps more advanced users to explore the impact of certain inputs on output.

Intended to help designers and planners forecast energy consumption of buildings, the app can use inputted data to produce a simulated total energy graph regression throughout the year to see which features have the highest impact. The data can also be configured for different metrics and accuracy, allowing users to explore patterns of energy consumption.

Building energy simulations often have to deal with uncertainty from input parameters, such as the number of occupants, schedule of occupants and occupant habits, as well as simplifications in modeling, whether physics-based or data-driven. Creating more accurate models can be difficult because no single tool can simulate the whole process and it might require more parameters and hence have more parametric uncertainty. With their new app, CGBC researchers have created a more accurate system by analyzing historical data to create a baseline to predict uncertainty in modeling of building data.

Existing tools normalize energy consumption by weather using simple regression methods, while the center utilizes machine learning with the Gaussian process which requires fewer training data points and higher prediction accuracy compared to other machine learning techniques. Additionally, it can evaluate the impact of system control parameters on energy consumption for potential optimization. While it was designed for use with a time-series plot, the app is flexible and can be used to analyze a range of data, such as stock market analysis, power generation and even health changes.

Harvard CGBC receives Microsoft Azure Research Award

Harvard CGBC recently received a Microsoft Azure Research Award, which gives the center sponsored access to Microsoft Azure, a cloud computing platform and infrastructure. It is used to build, deploy and manage applications and services through a global network of Microsoft-managed data centers, and the award offers free access to cloud computing resources for projects across the world. CGBC researchers will use the award to support a computational research and development agenda.  Specifically, the center will employ the platform for a range of the following research projects: using sensors, machine learning algorithms and prototypes to assess energy optimization of buildings; investigating intuitive and efficient smart building data visualization, monitoring and analyzing interior air quality; monitoring and analyzing building surfaces; documenting and annotating periodic building performance and personal status; and, assessing virtual environments and interfaces.

CGBC researchers publish article on natural ventilation design simulations, influence region

CGBC researchers’ recent article about the Influence Region in simulations for natural ventilation design was accepted and published in a new edition of Applied Energy, a journal that offers “information on innovation, research, development and demonstration in the areas of energy conversion and conservation, the optimal use of energy resources, analysis and optimization of energy processes, mitigation of environmental pollutants, and sustainable energy systems.” Zheming Tong, Yujiao Chen and Ali Malkawi investigated the accuracy of natural ventilation analyses relying on how the CFD domain and Influence Region is chosen. This study demonstrates the importance of assessing the sensitivity of the selected Influence Region in CFD simulations to reduce unintended modeling errors and computing expense.

Richard Rogers to deliver CGBC’s Annual Lecture 2016

On Tuesday, October 18, world-renowned architect Richard Rogers will deliver the 2016 CGBC Annual Lecture at the Graduate School of Design. Situated within the Harvard GSD Lecture Series, the lecture intends to expose a large audience of students, faculty and members of the public to the importance of green design and planning by highlighting the work of key leaders within this movement. Richard Rogers is a founding partner of Rogers Stirk Harbour and Partners and a Pritzker Prize Laureate. Over a career spanning more than fifty years, he and his partners have advised national & city leaders and designed many buildings including Centre Pompidou, Lloyd’s of London, the Bordeaux Law Courts, the Welsh Assembly, the Millennium Dome, the Leadenhall Building, and new terminals at Madrid Barajas and London Heathrow airports.  The CGBC Annual Lecture was inaugurated last fall by Norman Foster.

Harvard Office for Sustainability publishes 2015 University-wide Sustainability Report

On Wednesday, April 27, the Harvard Office for Sustainability published its 2015 University-wide Sustainability Report detailing some of the ways the university is creating a healthy, thriving, and sustainable community. The report discusses enhances to the well-being of people and the planet, with a focus on emissions and energy, campus operations, nature and ecosystems, health and well-being, and culture and learning. More than 1,300 energy efficiency measures have been implemented across campus. As a result, University-wide energy consumption has dropped by 2%, even after accounting for 15% growth in square footage and energy-intensive space. Excluding growth, energy use has been reduced by 16%.
