Non-residential building occupancy modeling. Part I.


Idea: providing occupancy driven energy efficiency model. Since about 40% of building energy goes to HVAC(heating, ventilation and air conditioning) it is quite good idea to use these equipment when it is really required,e.g. switch on the air conditioner or ventilation when people in a room
The study discusses approaches towards optimizing energy consumption of commercial buildings. Such task is considered to be a part of more broad topics, e.g. smart buildings, green buildings. During the past years, the number of papers dedicated to energy efficiency optimization in buildings has been growing which confirms societal concern about finding the most efficient methods of improving energy usage by buildings. To maximize building’s energy efficiency various methods are known and can be split into re-organizational advances and strengthening currently employed management systems [1], [2]. This methods include triple glazing, different types of insulation techniques such as wall and windows insulation as well as heating and lighting control.Despite a range of approaches towards solving this problem, such as building envelope design, window parameters, climate conditions, the proposal will focus on HVAC(Heating Ventilation Air Conditioning) systems as well as appliances and lighting. In this section, the paper will argue about some associated research papers and represent outlook of this overview. Additionally, it will underline main methods and techniques in the topic of the study as well as consider primary challenges.

Speaking in a simple terms, if BMS (building management service) engineer or building owner will want to know occupancy predictions for a particular room/buidling sector at particular time. Having such occupancy model would be helful for many applications, including energy efficiency (manage lights, heating, ventilation). Also, speaking about shopping and entertainment malls, one might want to predict how many visitors boutique or shop may expect at a time or panning some advertising campaign to catch the time when number of people is maximum.

Things that required to build up a occupancy prediction model
As in most machine learning problems the first step is to acquire appropriate dataset. After some research, I encounterd several public datasets, the most interesting ones are UCI, OpenEI and GitHub buildings datasets.

Machine Learning. Part II.

Non-residential building occupancy modeling. Part II. Occupancy classification So dataset was taken from this place . The dataset comprised of different sources: surveys, data logging from sensors, weather, environment variables. Total feature list consist of 118 features and can be grouped as general (occupancy, time), environment (indoor, outdoor), personal characteristics (age, office type, accepted sensation range etc), comfort/productivity/satisfaction, behavior (clothing, window, interaction with thermostat etc ), personal values (choices on different set points). It contains data on 24 occupants whether it private office or joint one, the first task is to implement binary classification of each occupant using some input data from sensors and time. For rapid protoyping I will use python Tensor Flow wrapper Keras along Anaconda framework. First, loading all required libraries from keras.models import Sequential from keras.layers import Dense import numpy ...

Machine Learning. Part III

Non-residential building occupancy modeling. Part III. Defining occupancy patterns. Recalling from the last part II we have got building occupancy data-set. In this part I will apply k-means cluster algorithm in order to identify typical occupancy patterns with daily resolution. To better visualize input data we have, see the following table below: Month Day Weekday Minutes Temperature Relative humidity Air Velocity Occupancy out of 24 7 31 3 779 23 89 1.3411 0 8 1 4 823 24 88 3.578 2 ... ... ... ... ... ... ... ... So I changed initial data by transforming Matlab absolute time readings into month, day, weekday(where 1 - Sunday,2 - Monday etc.), day time in minutes (with 15 min time step); temperature,velocity and humidity is general outdoor data; and finally total building occupancy.
