BIM – An Innovative Tool for the Local Construction Industry by Clarabel Versace

The local construction industry tends to use traditional methods for delivering contracts. Few if any, are implementing the latest technologies and the same issues keep recurring during the construction phase. Lack of communication between the different design companies and the contractors leads to workability issues and substantial variations resulting in deadlines and budgets not being met. The latest advancement in the construction industry is Building Information Modelling (BIM). BIM has been implemented successfully in various countries during the past decade. This presentation focuses on BIM, particularly at the design stage and aims to find out its benefits for the local industry. This presentation focuses on the design stage with a good look into the design software to understand how it works and why it is beneficial for BIM. However, other phases are taken into consideration, with a case study on an existing local project where BIM software was used.

 

Minimal Retrofitting Passive Measures for Traditional Maltese Townhouses, with Special Emphasis on the Elimination of Wall Ventilators: A Case Study in Kirkop, Malta by Farren Grixti

When dealing with townhouses in Malta, it has been significantly difficult to find a balance between maintaining thermal comfort and yet providing adequate ventilation that aids the wellbeing of occupants. Ventilation has been long recognised to be crucial for enabling good indoor air quality and occupant comfort as a result of the fresh air that is provided. This study highlights how such residential stone buildings can have minimal retrofitting approaches in order to make use of passive strategies, along with the provision of a simple fan operated heat recovery improvised design system.

The study focuses on the elimination of the current standard ventilation holes - that even though deemed necessary by local regulations for internal ventilation, are however uncontrolled and have proven to be main sources for heat losses and cold air infiltration in winter. Such evidence is supported by means of infrared thermal camera imaging and the use of data loggers so as to study their effect on internal temperatures, relative humidity and carbon dioxide levels. Furthermore, retrofitting of existing residences is essential in order to progress towards energy efficiency, carbon reduction targets and sensible mitigation of climate change.

 

The Impact of Internal and External Polyisocyanurate Insulation Systems on the Domestic Household: A Cost Analysis by Samuel Vella

As the norm, most new buildings in Malta are apartment blocks. In fact, this presentation takes into account the most exposed living space available for users to buy - the penthouse, which is a highly sought after, so to say, apartment. The aim of this study is to determine the most thermally efficient and cost-effective insulation method between external and internal installation, while also taking into consideration the capital and running costs of each specimen and thus, comparing them to the normality of not having any insulation installed.

The results were obtained by simulating every scenario with the use of the renowned Design Builder Energy Plus Software, with the five (5) results representing a traditional envelope built with HCB (Hollow Concrete Blocks) and a concrete roof without insulation, 30mm and 50mm internally fitted PIR on both walls and roofs, and lastly 30mm and 50mm externally fitted PIR on both walls and roofs. All these specimens are available in Malta, and as such, all specifications and pricing are derived locally.
