This paper describes a benchmark consisting of a set of synthetic measurements relative to an office environment simulated with the software IDA-ICE. The simulated environment reproduces a laboratory at the KTH–EES Smart Building, equipped with a building management system. The data set contains measurement records collected over a period of several days. The signals correspond to CO2 concentra...

Our research addresses how to integrate exploration and localization for mobile robots. A robot exploring and mapping an unknown environment needs to know its own location, but it may need a map in order to determine that location. In order to solve this problem, we have developed ARIEL, a mobile robot system that combines frontierbased exploration with continuous localization. ARIEL explores b...

This study investigated the effect of moving from single-occupancy offices to a landscape environment. Thirty-two visual display unit (VDU) operators reported no significant change in visual discomfort. Lighting conditions and glare reported subjectively showed no significant correlation with visual discomfort. Experience of pain was found to reduce subjectively rated work capacity during VDU t...

Knowing the presence or the actual number of occupants in a space at any given time is essential for the effective management of various building operation functions such as security and environmental control (e.g., lighting, HVAC). In the past, motion detection using Passive Infrared (PIR) sensors has been widely deployed in commercial buildings and can provide data on “presence” status. Howev...

Carnegie Mellon University {jgluck, ckoehler, jmankoff, anind, yuvraj.agarwal}@andrew.cmu.edu ABSTRACT Heating, Ventilation, and Cooling (HVAC) systems are often the most significant contributor to the energy usage, and the operational cost, of large office buildings. Therefore, to understand the various factors affecting the energy usage, and to optimize the operational efficiency of building ...

BACKGROUND hospitals are under pressure to reduce waiting times and costs. One strategy that may be effective focuses on optimising the flow of emergency patients. OBJECTIVE we undertook a patient flow analysis of older emergency patients to identify and address delays in ensuring timely care, without additional resources. DESIGN prospective systems redesign study over 2 years. SETTING th...

A simulation algorithm is proposed that predicts the lighting energy performance of manually and automatically controlled electric lighting and blind systems in private and two-person offices. Algorithm inputs are annual profiles of user occupancy and work plane illuminances. These two inputs are combined with probabilistic switching patterns, which have been derived from field data, in order t...

Office cooling systems are controlled with on/off control according to typical occupancy patterns. During unoccupancy, the remain switched off reduce unnecessary energy consumption. occupancy, however, in operation decrease indoor air temperature, which is increased during set-point temperature. The time required temperature defined as “recovery time”. According recovery time, thermal comfort a...

Abstract Detailed buildings energy audits require dynamic simulation models based on hourly input data. This paper presents the calibration and validation of an office building model for heating cooling services. Simulation are carried out by DesignBuilder software. Measured supplied generation system used model. Employee behaviour with reference to occupancy profiles indoor temperature setting...
