Daylight Performance and Optimization with Light Pipe in the Design of Modern Art Museum Abuja.
ABSTRACT
and art collect, , analyse and historical artefacts and various of the past. Light is a basic requirement in museum design for the appreciation of artwork.
However, achieving daylight in museum spaces particularly in a tropical climate is challenging due to its effect on artefacts and this has resulted in dependence on artificial light. Daylighting has an important role in sustainable architecture as it affects the energy consumption in a building and also promotes work efficiency through promoting good human health.
In view of this, it is necessary to improve daylighting in museums in order to reduce electricity demand and increase the comfort of the users and also as a tool for advanced architectural creativity.
Hence, the aim of this study is to test the daylight performance of light pipes for optimum lighting in museum design in tropical climates. The study makes use of a case study approach and quasi-experimental (simulation) to test the daylight performance of the tubular light pipe.
Literature review establishes the level of daylight requires in museum spaces, while case study find out the types of collections in Nigeria museums and daylight level in the selected museum galleries with light metre readings on sensor points at 900mm above floor level between 1:00 pm-3:0pm.
To test for the light pipe performance, a standard room of 3mx3mx3.6m was modelled, with a light pipe of different aspect ratio (diameter to length) in Ecotect and result visualise in radiance and Days.
INTRODUCTION
A vital front in the fight against global warming is the reduction of fossil fuel consumption and the resulting fall in Greenhouse Gas Emissions (GHG). One component of realizing this is to use natural lighting rather than electric light to illuminate indoor spaces.
According to Oakley, Riffat and Shao (2000), using daylight in buildings can result in a 20-30% drop in energy usage, a sizable saving. Similarly, Reinhart and Wienold (2011), sees daylight as an effective means of saving energy and reducing environmental impact.
While Chirarattananon, Hien, Chaiwiwatworakul and Chirarattananon (2010), opines that daylighting offers great potential for applications in tropical climates because daylight is voluminous and highly available near the equator.
Good quality daylight can influence physiological responses and improve health conditions in working environments (Mayhoub and Carter, 2011). It is, therefore, necessary to improve daylight performance in museums in order to reduce electricity demand and increase the comfort of the users and also as a tool for advanced architectural creativity.
A museum is a cultural institution, particularly in Nigeria it has to do with collection, preservation, display and interpretation of cultural objects for the advancement of knowledge.
It is the treasure house of the human race as it stores memories of people, their cultural dreams and hopes (Nnimmo, 2012). There are needs for every society to persevere its culture and historical material or intellectual properties for prosperity, therefore the need for museums becomes important.
Museums in Nigeria and Africa at large are facing a hard time surviving due to low patronage (Kabir, 2016). Preliminary visual observation indicated that most museums in Nigeria are ancient and colonial monuments. Which are considered old, quiet and lonely places.
Research by Baewon Koh and Meyer (2015), 2 shows that most of the daylighting energy-saving measures can help save money while enhancing museum aesthetics and staff productivity which in turn attract public interest.
