Lifecycle Health Assessment Model for Sustainable Healthy Buildings

Abstract

A system to analyze, assess and manage the health performance of resources and spaces throughout the project lifecycle shall be established to ensure sustainable healthy buildings. Decisions made in the planning, design, construction, and operation and management (O&M) phases must help sustain the health performance of buildings at the level specified by clients or the relevant laws. For this reason, it is necessary to develop a model to ensure the consistent management of performance, as such performance varies according to the decisions made by project participants in each phase. The purpose of this research is to develop a Lifecycle Health Assessment Model (LHA) for sustainable healthy buildings. The developed model consists of four different modules: the Health-friendly Resources Database (HRDB) module, which provides health performance data regarding resources and spatial elements; the Lifecycle Health-performance Tree (LHT) module, which analyzes the hierarchy of spatial and health impact factors; the Health Performance Evaluation (HPE) Module; and the Lifecycle Health Management Module, which analyzes and manages changes in health performances throughout the lifecycle. The model helps ensure sustainable health performances of buildings.

Health performance and cost management model for sustainable healthy buildings

“…14 The objective is to provide healthy spaces for the healthy lives of building residents. Therefore, the health performance of spaces should be quantitatively evaluated and managed.…”

“…5 To complement the maintenance of the health performance of a building sustainably, the life cycle health management (LHM) model was proposed. 14…”

“…Construction cost, quality and time are technical health performance factors, as shown in Figure 2. 14

…”

“…The management should be based on the degree of health performance as baseline requirement as stipulated by legal criteria (based on government’s building standards) throughout the building’s life cycle. 14 Using previous studies, 5,17,18 the factors affecting the health performance of a building are analysed; to identify and to determine the elements needed to achieve healthy buildings. The management model is proposed by considering the stakeholders’ responsibilities and building health factors such as indoor air quality (IAQ), noise, lighting and heating ventilation and air conditioning (HVAC) that could satisfy the client’s needs.…”

“…11 Moreover, clients' satisfaction is being recognized as one of the most significant challenges confronting the modern construction industry. 11 In a similar way, several studies have been done on the construction issues such as sustainable building, [12][13][14] building life cycles, 15,16 health performance evaluation factors, 17,18 management of finishing buildings, 19 hazardous materials 20 and cost and time overruns. 21 Addressing the health and well-being problems of buildings could require a raising of construction cost.…”
