Abstract

The current paradigm of building design is evolving rapidly and building developers are beginning to dopt sustainable building practices across Canada. Attaining a sustainable built environment is challenged by the complexity of decision-making and stakeholders need to examine a large number of sustainability metrics to support a 'good decision'. Each sustainable building development has a design path unique to the values of the building stakeholders.This project outlines a framework that assists decision-makers in achieving a building design that is closely aligned to their values and requirements.

This paper outlines a decision-support system that brings together a broad set of sustainability metrcs, both quantitative and qualitative, into a multi-criteria decision analysis tool where decision-makers can contrast and compare the simulated performance of competing building dsigns. The performance modeling tools include environmental life cycle analysis (Athena EIE), financial modeling by life cycle costing (UBC ID), energy modeling (eQuest). Benchmark information, required for informing decision-makers of baseline conditions, is derived from the UBC_LCA database, UBCPT, and UBC Operations data. Social benchmarks are determined from the UBC Post occupancy protocol under development at UBC. These metrics and benchmarks are synthesized and integrated into the multi-critera decision analysis framework as optional attributes from which decision- makers can select as decision criteria.

set of sustainability indicators are developed from metrics specified by ISO 21912-1, LBL, ASHRAE andUBCs own criteria developed as part of the UBC Buchanan and CIRS projects. Finally, the paper discusses how decision-makers can express their preference for each critria so that their expertise and values are accurately reflected when analyzing the criteria performance results. Methods to check for 'future-proofing' are also discussed in terms of checking the life cycle models for resilience to future change.
