Enhancing the human experience: algorithms to drive individual workplace comfort

1 CommentBy

When it comes to workplace comfort, researchers at Purdue University are proving the theory that one size doesn’t fit all.

An ongoing study at the Purdue University Center for High Performance Buildings (CHPB), in partnership with JLL, is looking at the effect of customizable indoor environment conditions on employee productivity and satisfaction and building energy consumption. The goal of the two-year project, “Development of self-tuned indoor environments,” is to use measures of individual preferences to come up with smart building technology solutions.

“Essentially we are developing algorithms that can learn occupant preferences accurately and efficiently,” said Associate Professor of Civil Engineering Panagiota Karava, one of the researchers on the project.

Founded in 2013, the CHPB has quickly emerged as a leader in the smart building innovation space. Supported by partnerships with industry leaders, the CHPB takes a multi-disciplinary approach to its research projects, by bringing in experts in mechanical, civil and electrical engineering, as well as specialists in psychology and human behavior.

JLL has partnered with the CHPB on 13 research projects, including this one. The study is collecting data from over 200 participants in private and open-plan offices in an on-campus building that is a living laboratory. Each private office is equipped with dimmable electric lights, motorized shades and a Variable Air Volume system. In one sub-study, sensors measured temperature, light levels and occupant actions as participants were asked to engage in a regular 8-hour workday and interact with the customizable control systems from their desks. … Read More

A groundbreaking approach known as Total Impact (TI) is helping companies to realize the impact they have not only on workplace and employees, but also on society, the environment and the economy. The methodology builds off existing financial reporting as well as corporate sustainability and integrated reporting.

JLL is currently piloting a TI assessment in the UK. While JLL is still in the process of calculating impacts, Sophie Walker, UK Head of… Read More

Energy storage: achieving the cardinal rule of electricity

0 CommentsBy

The cardinal rule of electricity is that supply must equal demand at all times. When you flip a light switch, you expect the lights to go on. This rule has challenged utilities, regional transmission organizations, independent system operators and commercial, industrial and residential consumers since the time of Edison. Generally fossil-fired and nuclear generation must run continuously while renewable energy is subject to the intermittency inherent in solar and wind resources. … Read More
