Abstract

Increasingly challenging climatic conditions could significantly impact on the environmental performance of healthcare facilities. Current climate and environmental related challenges are complex which need to be addressed by first analysing the potential impact of climate change on building performance, and then using this to develop responsive environmental design solutions. Given the degree of complexity and the number of multiple variable parameters that need to be considered, the approach proposed by this paper is referred to as ‘parametric environmental design’. The evidence to support the development of a proposed parametric environmental design framework has included related: literature review; multiple case study; post occupancy evaluation; environmental review; energy use audit; energy performance benchmarking; thermal scenario development; thermal scenario testing; focus group workshop; environmental design; and environmental monitoring. This paper focuses on the thermal scenario development and testing aspects through the use of parametric modelling and environmental simulation for thermal analysis. The aim of this paper is to assess the potential role of parametric environmental design in facilitating low energy healthcare facility design and performance, and this will be fulfilled through the use of the following methods: literature review and tool testing for evaluation of the features and capabilities of building information modelling (BIM), and parametric modelling and environmental simulation tools that support the development of purpose-built parametric models for thermal analysis; and thermal scenario development and testing for thermal analysis of 4 purpose-built parametric models of a healthcare single bedroom for the elderly to be situated in 4 cities in England. This paper determined that 4 purpose-built parametric models – all with the same volume, and representative of a healthcare single bedroom for the elderly (as a sample of a healthcare facility) situated in 4 cities in England – had differing heating requirements, and this necessitated active and passive environmental design strategies and controls to facilitate low(er) heating energy use. Furthermore, parametric modelling and environmental simulation as an aspect of a proposed parametric environmental design approach facilitated this assessment.
