Thermal Performance Compliance Analysis of Porta-Cabin Shelters Using EN ISO 13786 and EN ISO 6946

Abstract

Porta Cabin Shelters are temporary dwellings constructed with Sandwich Panels, and used in operational sites by Oil and Gas Firms in Nigeria and Africa. This study carried out thermal performance analysis of Standard Porta Cabin Shelters used in Nigeria Liquified Natural Gas (NLNG) operational Sites using EN ISO 13786: 2017 and ISO 6946:2017 Calculation Methods and Procedures. The Calculation results were tested against the European Building Regulations Part L for compliance. This study reveals that the Porta Cabin shelters failed the compliance test. Analysis for possible compliance was undertaken and the outcome shows that construction of the roof, ceiling and walls with insulator (Sandwich Panels with Polyurethane Foam (PUF) as core materials thickness within the range of 80mm to 120mm) comply with the provision of European Building Regulations. Further analysis shows that adding about 80mm to 110mm thickness of insulator layer to the floor thermal layers will correct the major non-compliance in the floor construction and enhance thermal comfort of the shelters.
