A New Trend for Indoor Lighting Design Based on A Hybrid Methodology

Most power system planners are interested in the savings of electrical power consumption. Various references demonstrate that the highest consumed power is by the lighting systems standing around 19% of worldwide energy consumption. This article presents novel design methodology leading to maximizing revenue due to savings in electrical energy consumption through energy efficient installations.

Experimental Investigation of Overall Energy Performance in Algerian Office Building Integrated Photovoltaic Window under Semi-Arid Climate

Building integrated photovoltaic (BIPV) energy has now become one of the most significant renewable energy alternatives for providing natural daylight and clean energy. As such, this study was conducted for the first time in Algeria to experimentally evaluate the BIPV window energy and lighting energy savings of a typical office building under the semi-arid climate condition.

Heliostats Daylighting System for Multi-floor Buildings

Daylighting has been considered as a major part of sustainable buildings for saving electric lighting and providing benefits such as, health, visual comfort, and productivity of the occupants. A daylighting system enables the sunlight to capture and deliver it in the interior spaces that cannot be illuminated through windows.

Annual Performance Assessment of Complex Fenestration Systems in Sunny Climates Using Advanced Computer Simulations

Complex Fenestration Systems (CFS) are advanced daylighting systems that are placed on the upper part of a window to improve the indoor daylight distribution within rooms. Due to their double function of daylight redirection and solar protection, they are considered as a solution to mitigate the unfavorable effects due to the admission of direct sunlight in buildings located in prevailing sunny climates (risk of glare and overheating).

Energy Saving Generated Through Automatic Lighting Control Systems According to the Estimation Method of the Standard EN 15193-1

The standard EN 15193-1:2017 “Energy performance of buildings - Energy requirements for lighting” introduced a detailed method to calculate the energy demand for lighting in buildings. The method contains a calculation of the daylight supply, which accounts for the impact of lighting control systems, both daylight-linked and occupancy-based. Th.

The Role of Orosi’s Islamic Geometric Patterns in the Building Façade Design for Improving Occupants’ Daylight Performance

The form of the building facade significantly affects the amount of useful daylight admitted in the interior space. Striking a balance between the visual comforts of occupants and taking advantage of daylight is always a challenge and, therefore, investigating complex, geometric forms of Orosi patterns can be an effective way of improving visual comfort alongside the aesthetic aspects.

Evaluation of Daylight Availability for Energy Savings

Dynamic daylight simulations are very useful instruments in daylighting design process. They allow an in depth analysis of indoor daylight availability levels and define if they are adequate to perform a particular visual task. Their results can be used to design shading devices or lighting control systems and compare different technical solutions.

Optical Characteristics of Traditional Portuguese Azulejos: Mixing Colors to Obtain “Cool” Building Façades

The need to reduce energy consumptions in buildings brings modern research to focus on the use of natural sources. In this context, the interest towards traditional architecture has been fueled, since one of the characteristics identifying it is the intuitive and intrinsic link between the building and the surrounding environment.

A Field-validated Multi-objective Optimization of the Shape and Size of Windows Based on Daylighting Metrics in Hot-summer Mediterranean and Dry Summer Continental Climates

This study aims to determine the optimum size of windows based on the window-to-floor ratio (WFR) for the main cardinal directions in Hot-summer Mediterranean (Csa) and Dry Summer Continental (Dsa) climates (Köppen–Geiger classification system) by carrying out a multi-objective optimization that relies on three dynamic metrics of Useful Daylight Illuminance (UDI-a (autonomous)), Daylight Autonomy (DA), and Annual Sunlight Exposure (ASE1000,250) in Radiance version 5.1..

Effective Use of Daylight in Office Rooms

The rational use of daylight can significantly reduce the cost of electricity for artificial lighting. This research aims at investigating the parameters of translucent structures of building envelope, and the value of daylight factor, for which maximum efficiency of daylight usage is achieved in office rooms.

Automatic vs Manual Control Strategy for Window Blinds and Ceiling Lights: Consequences to Perceived Visual and Thermal Discomfort

A case study to evaluate the occupants' satisfaction in relation to two different control strategies (fully automatic and manual) for blind and ceiling lights use in cell offices was carried on in Trondheim, Norway. A group of 11 participants with varying age, gender, and ethnicity, used two test cells of a laboratory as a workspace primarily carrying out office tasks at a personal computer for a total of 19 calendar days.

Development of Fresnel-based Concentrated Photovoltaic (CPV) System with Uniform Irradiance

Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell.

Daylighting metrics: an approach to dynamic cubic illuminance

Advances in research work in the field of numerical analysis of daylight performance have generated in-depth knowledge on photometric measurements of daylight quality. Most dynamic metrics are based on illuminance, which is a two-dimensional concept insofar as it is concerned with the density of luminous flux incident at a point on a surface.

Lighting to Enhance Wayfinding for Thai Elderly Adults in Nursing Homes

The main purpose of this study was to explore the effects of lighting and other environmental variables in terms of the colour, signage, and furnishings on the indoor wayfinding of Thai seniors in a nursing home. Three major studies were conducted. The first study aimed at exploring the effects of the lighting parameters in rooms in a nursing home environment, which were the opening type, luminaire type, lamp type, and the type of view-out on the wayfinding performance of Thai elderly people.
