STRATEGY FOR VISUAL COMFORT CONTROL – THROUGH HDR LUMINANCE MAPPING BY A LOW-COST CONTROLLER SYSTEM

Ph.D. Thesis by Dr. Charlotte Goovaerts, Vrije Universiteit Brussel (VUB), Department of Architectural Engineering

Daylighting in offices creates a comfortable and healthy working environment for its users. Additionally, it can decrease the electricity consumption for artificial lighting. However, maximizing the amount of daylight can cause some issues. In Northern European climates, visual discomfort is the most negative side effect from windows. Also, excessive short-wave directly-transmitted solar radiation and long-wave indirectly-transmitted energy can cause thermal discomfort and an increased energy demand for cooling. […]

EXPERIMENTAL STANDARDS IN SUSTAINABILITY TRANSITIONS: INSIGHTS FROM THE BUILDING SECTOR

Ph.D. Thesis by Dr. Lara Anne Hale, Doctoral School of Organisation and Management Studies, Copenhagen Business School | Image by Adam Mørk

It is already challenging to make small changes to buildings – painting the window panels, upgrading the kitchen, or even (as many Copenhageners are familiar with) installing a shower. But there is a pressing need for more extensive change – we need to learn how to build again and build more sustainably. As part of the EU Marie Curie project […]

A COMPREHENSIVE GUIDE TO DAYLIGHT, ENERGY AND INDOOR CLIMATE PERFORMANCE OF BUILDINGS

A good indoor climate with generous daylight levels and provision of fresh air from outside is the key to making homes, offices, kindergartens and schools healthy buildings to live and work in. Daylight, Energy and Indoor Climate Book is a gathering of essential knowledge on the effects of windows, and how they affect various aspects building and human performance.

“With the Daylight, Energy and Indoor Climate book (DEIC), we aim to share our insight and knowledge by providing specific advice and […]

APPLICABILITY OF CLIMATE-BASED DAYLIGHT MODELLING

Ph.D. Thesis by Dr. Eleonora Brembilla, Loughborough University

Climate-Based Daylight Modelling (CBDM) can be defined as the assessment of the luminous conditions within the built environment that makes use of representative climate data to recreate realistic sky luminance distributions, at hourly or sub-hourly consecutive steps, by means of physically accurate lighting simulation tools. CBDM made its appearance among other Building Performance Simulation disciplines relatively recently, marking a profound change from the previously established daylighting analyses, such as the Daylight Factor and Sun […]

TEMPORAL EFFECTS IN GLARE RESPONSE

Ph.D. Thesis by Michael G. Kent, the Department of Architecture and Built Environment, University of Nottingham

Discomfort glare is considered to be an annoyance or distraction caused by sources of non-uniform or high luminance within the field of view of an observer. There are still significant gaps in our understanding of the conditions that characterise the magnitude and occurrence of discomfort glare, this being especially evident in the presence of large sources of luminance such as windows. The large degree of […]

DAYLIGHTING DESIGNED THROUGH ARCHITECTURE. CLIMATE-BASED LUMINOUS AND THERMAL ANALYSIS OF SOME DAYLIGHT-RELATED ARCHITECTURAL FEATURES

Ph.D. Thesis by Dr. Paula M. Esquivias Fernández, University of Sevilla, Department of Architectural Construction (ETSA)

The objective of this thesis is to provide a decision tool to evaluate the daylighting potential of a space considering also its thermal component in order to balance the presence of daylight illuminances and solar heat gains to provide enough daylight for visual tasks avoiding situations of discomfort, such as glare or overheating.

This research is based on the evidence that the amount of daylight that enters […]

BRINGING THE PAST TO THE FUTURE – INTERVIEW WITH IVA2018 JURY MEMBER SASA BEGOVIC

posted by International VELUX Award 2018

Wood and acoustic panels, suggest that the hall is a large living room for athletes. Steel girders of 55 meters span and different heights enable the natural light illumination of the sports hall.

“Learn about your history, learn about your craft and learn about what is happening around you” says Saša Begović, founding partner and premier architect of 3LHD Architects, urging students to search their own heritage for inspiration for their International VELUX Award projects.
