Interactive Thermal Comfort Tools add to CBE’s Public Offerings

Interactive Thermal Comfort Tools add to CBE’s Public Offerings

We launched a new suite of free and publicly available online resources to facilitate academic and professional studies of thermal comfort in buildings. These tools can be used to inform questions about thermal comfort, and to encourage the design of climate-responsive and comfortable low energy (and ZNE) buildings.

CBE Research on Ceiling Fans May Help Tackle Future Global Challenges

CBE Research on Ceiling Fans May Help Tackle Future Global Challenges

CBE research has quantified what we all know intuitively: ceiling fans can provide acceptable comfort at temperatures that otherwise would be stifling. This enables passive solutions in milder climates, and may reduce the reliance on air conditioning in climates where passive solutions alone are not sufficient.

New Funding Awarded: Energy Product Evaluation

New Funding Awarded: Energy Product Evaluation

In March, CBE’s research team received news of a successful proposal led by the UC Davis Energy and Efficiency Institute to form a new California Energy Product Evaluation (Cal-EPE) Hub. The objective of the Hub is to evaluate commercially available technologies that are relevant to institutional and commercial customer procurement processes, including products related to energy efficiency, renewable distributed generation, and distributed storage.

Comfort in Buildings, and Vehicles Too

Comfort in Buildings, and Vehicles Too

The emerging trend toward smart electric vehicles is creating new opportunities for synergistic innovations that are applicable to both buildings and cars. Model-based control concepts, greatly advanced by the automotive sector, are now being tested in the control of complex commercial buildings. These synergies, what we might call the building-automotive nexus, are also reflected in CBE’s body of research on thermal comfort.

Japan-based Daikin Joins CBE

Japan-based Daikin Joins CBE

This spring, CBE welcomes global HVAC manufacturer Daikin as one of its newest industry members. Having yet to fully establish themselves in North America, you could be forgiven for not recognizing their brand. However, with annual sales of over 17 billion dollars, Daikin is indeed a global leader in air conditioning equipment.

Using an Internet of Things Platform to Improve Comfort Prediction

Using an Internet of Things Platform to Improve Comfort Prediction

The emerging Internet of Things offers opportunities to improve how we design, measure and operate buildings. CBE’s research team conducted a six-month field demonstration of a system using IoT-connected heated and cooled office chairs. Results demonstrated high levels of comfort seen in few buildings. In addition, the data from occupants’ use of the chairs can be used to predict thermal comfort more accurately than methods previously available.

New Capabilities for the CBE Thermal Comfort Tool

New Capabilities for the CBE Thermal Comfort Tool

An important goal at CBE is to provide tools to assist industry professionals to create energy efficient and comfortable buildings. In 2013 we first launched the online CBE Thermal Comfort Tool as a way to help practitioners predict thermal comfort in buildings, based on ASHRAE Standard 55. We are excited to announce expanded capabilities in the most recent version of the tool.

CBE’s “Changing the Rules” Demonstrates an Occupant-Based Paradigm for HVAC Control for Energy Savings and Improved Thermal Comfort

CBE’s “Changing the Rules” Demonstrates an Occupant-Based Paradigm for HVAC Control for Energy Savings and Improved Thermal Comfort

CBE’s research team recently completed a project with goals of making buildings occupant-responsive in real time, and addressing outdated rules-of-thumb that lead to poor energy performance and occupant comfort. Findings demonstrated that “personal comfort” chairs led to comfort satisfaction for nearly all test subjects. The project team also developed and tested innovative HVAC control methods offering significant energy saving potential.
