In the commercial building segment, Priva’s business currently specializes in Heating, Ventilation and Air Conditioning (HVAC) control, floor control and energy management.However,...

Performance assessment of a “do it yourself” double skin green façade for an existing office building

This project is based on two sustainable construction methods, namely up-cycling (reuse of materials) and vertical farming (green facades). These two concepts are combined to form a ‘Do It Yourself’ double skin façade, a double skin façade made with re-used sliding doors, which is aimed to be capable of developing ‘Edible Green’, which refers to...

Design Guide for better usable operable façade elements for offices in the Netherlands

In practice, operable façade elements (OFE’s) in office buildings are often not appropriate to use to gain control over the thermal environment and indoor air quality. This study was performed to provide the means for architects and façade designers to design better usable OFE’s and improve personal control over indoor air quality and thermal...

Identification of walkable space in a voxel model, derived from a point cloud and its corresponding trajectory

Navigation from a room inside a building to another room inside a building which is across the street consists of three parts: first, the indoor part at the building where you start your journey. Secondly, the outdoor part and thirdly, another indoor part inside the building of destination. As regards to the outdoor environment, a navigation aid...

The Blue Bonus: Using Water to Enhance Office Space Experience

This study focuses on the concept of bonus factors in office buildings. Bonus factors are those elements of a building which have positive psychological effects on the building user: the office employee. In a literature review, six bonus factors are found: daylight, outside view, the use of plants inside, a natural climate which is both adaptive...

Indoor Localization using Narrowband Radios and Switched Antennas in Indoor Environments

Indoor positioning using Bluetooth addressed a great concern. The properties of narrowband usage, low energy consumption and universality on devices attract numerous customers and promote researchers to investigate potential of Bluetooth in indoor positioning field. It has already supported Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) in...

Bring Nature Indoor: by integrating an active living wall system within a Lung Rehabilitation Center at the Marine area

Over the last couple of decades, climate change and energy crises have led to an increased interest in reducing the building energy consumption. To reduce the energy consumption buildings are designed airtight. This leads to the accumulation of indoor air pollutants, which are associated with multiple health and discomfort problems. Poor indoor...

Indoor 3D Reconstruction from a Single Image

3D indoor reconstruction has been an important research area in the field of computer vision and photogrammetry. While the initial techniques developed for this purpose use sensor devices and multiple images for data acquisition and extracting 3D information and representation of the scene, with the advent of deep learning techniques, there has...

A non-intrusive sensor-based product that optimises work experience

In the last few years the smart building market has grown exponentially and is estimated to be worth around 100 billion by the year 2025. The amount of active competitors, combined with the required time and effort to launch a new sensor-based product, makes it difficult to enter the market and slows innovation. WeAreReasonablePeople (WARP), a...

Form follows climate: A naturally air-conditioned elderly community in Heerlen

The project is an elderly housing in Heerlen, the Netherlands. Since the elderly are vulnerable to climate change, It's aimed to offer them more options of social interaction by providing suitable climate for different functions. The rich climate hierarchy corresponding to spatial hierarchy is the key. Instead of common interior and exterior...

Exploring a pure landmark-based approach for indoor localisation

Humans interact more and more with their environment through technology, recent decades have seen a huge increase in the need for and availability of Location-Based Services (LBS). Recently landmarks have gotten a renewed interest in the field of LBS , although already a quite old phenomenon. In both the outdoor and indoor environment they are...

Passive solutions for individual comfort systems: Creating a microclimate for open plan offices

In many countries people typically spend over 90 percent of their time indoors. Therefore, the quality of the indoor environment has a big influence on the health and wellbeing of people. Standards for thermal comfort state that 80 percent of the occupants need to express satisfaction with the thermal environment to be thermally comfortable....

SCIPoC: Semantic Classification of Indoor Point Cloud: A study into the possibilities of classifying indoor point cloud using a Deep Learning approach

With the constantly evolving range of applications for technology the quality and amount of data constantly increases as well. In this growing data environment, there is a constant search to provide more value to all data that is available for as little effort as possible. Our research tries to add such additional value by diving into the...

3D Representations for Visual Insight

As a method that can accurately represent 3D spatial information, point cloud visualisation for indoor environments is still a relatively unexplored field of research. Our client for this project, the Dutch National Police, requested a variety of potential solutions for visualising (unfamiliar) indoor environments that can be viewed by both...
