ABSTRACT

Museums are places of natural and human creativity as well as history. The aim of museums is to provide examples of each classification available for a field of knowledge. Museums employ two main strategies for its lighting which includes: daylighting and artificial lighting. This study was able to identify and discuss the different daylighting systems, and the existing museums which used daylighting were analysed properly to see how daylighting was harnessed in their respective internal spaces. The research methodology used for this research work includes case studies and extensive literature reviews. Deductions from these case studies showed the various natural lighting techniques used which include clerestory windows, luminous ceilings and cove luminaires. All of these played a major role in harnessing daylight in the museums studied. In the course of research, Lighting is significant in museum artifact display, as it helps with the interaction between the artifact and the human in a defined space. Daylighting, as it is significant to the artifact, if not properly controlled, can cause discomfort in the eyes of the observer, at the same time be destructive to the objects on display. Other methods used for introducing daylighting into the spaces include the use of diffuse lighting throughLuminous ceilings,skylights, cove luminaires and also clerestory windows which help light reflects deeper into the exhibition halls. The design parameters and considerations indicate that buildings using these methods use less energy to lighten up their spaces, at the same time improving visibility and appreciation of artifacts.

ABSTRACT

It is well ascertained that for water to penetrate a wall, this three conditions must be true at the same time and location: Water on the surface of the wall, An opening through which water may pass, Any one of five external forces which include surface tension, momentum, air pressure differences, gravity flow and capillary action. Capillary Action (Capillarity) is the movement of water (or any liquid) through a tube. Moisture which is the relative amount of water vapor contained is the air is generated through several source and cause lot of harsh effect on the building and its content. Possible strategies that will mitigate this effect are what this paper seek to highlight and resolve critically by emphasising the possible guidelines that will that will mitigate regular occurrence.

ABSTRACT

Buildings are meant to complete their service life before undergoing deterioration, but this has become a mirage in the building lifecycle because of negligence in the careful conceptualization of designs. Design for maintainability, with emphasis on access to maintenance deals with creating proper designs that will incorporate accessibility that will enhance and enable maintenance. This will mitigate building defects, combat inappropriate and buildings that are not conceptually sustainable in designs and thereafter increase the maintenance culture of buildings in Nigeria. The negligence of the subject matter has caused buildings to encounter multiple defects, deterioration, and obsolescence in edifice that would have served their functions completely before the end of their service-life. Therefore, this paper seeks to adopt an analytical approach through the comparism of related journals, books to resolving this ever-trending challenge in the building and construction sector.

Keywords: Design maintainability, building life cycle, sustainability, accessibility.
