This project, commissioned by the Co-operative Research Centre for Low Carbon Living (CRCLCL), aims to advance an important aspect of the National Energy Productivity Plan: specifically, Item 12, ‘improving energy productivity in government’.

This study was commissioned by Sustainability Victoria to deliver a greater understanding of the size and impact of lower-grade commercial office buildings across Victoria. 
The main goals of this report are:

The ultimate test of the business case for high performance low carbon building is to consider how the human benefits of these buildings could be reliably quantified to prove beyond all doubt the positive Return on Investment (ROI). After all, staff costs, including salaries and benefits, typically account for about 90% of business operating costs.

This study examines the sources of evidence that influence decision-makers who design or develop office buildings, and aims to explain why some managers engage more in evidence-based practice (EBP) than others. A mixed methods approach is conducted that combines quantitative results from 187 senior managers in the built environment and qualitative data from 18 interviewees. The respondents evaluated the use and trustworthiness of different sources of evidence, followed by an assessment of practitioners’ adoption and understanding of EBP.

The relationship between levels of energy efficiency and differing forms of commercial office workspace tenure is theoretically affected by the economic principal-agent problems of moral hazard and adverse selection. Tenure involving contracts gross with energy utilities is subject to the moral hazard of overconsumption of energy which results in lower measures of energy efficiency. Tenure involving contracts net of energy utilities is subject to underinvestment in energy efficiency leading to the adverse selection of buildings put to market.

High-temperature absorption chillers (double-effect and triple-effect) have a higher coefficient of performance (COP) than single-effect chillers. This can reduce the collector’s footprint and cost in a solar-cooling plant. Though single-effect, absorption chiller-based solar-cooling systems have been studied for the past 20 years, very little information is available on the performance benefits of high-temperature solar-cooling systems.

The main objective of this rapid review was to identify and organise recent peer-reviewed empirical evidence for the energy efficiency of new (not retrofitted) green-rated office buildings.

The WorldGBC has demonstrated that low carbon, resource efficient and environmentally sensitive buildings can enhance the health, wellbeing and productivity of building users. That is a very strong element of the business case for green buildings.
The report forms one of the first major outputs from WorldGBC’s Better Places for People campaign, designed to fast-track the demand for and supply of buildings which support and enhance the health, wellbeing and productivity of the people within them. Fundamentally therefore, this is about action.

Employers, building owners, designers, developers, and investors throughout the world are learning, in response to an increasing body of evidence, that office design affects the health and wellbeing of occupants in many ways and so it is a smart business move to create green buildings that are healthy.
Staff are the most valuable resource in most organisations, typically accounting for 90% of business operating costs, so even a 1% improvement in productivity can have a major impact on the bottom line and competitiveness of any business.

Thirty years of public health research have demonstrated that improved indoor environmental quality is associated with better health outcomes. Recent research has demonstrated an impact of the indoor environment on cognitive function. We recruited 109 participants from 10 high-performing buildings in five U.S. cities. In each city, buildings were matched by week of assessment, tenant, type of worker and work functions. A key distinction between the matched buildings was whether they had achieved green certification.

This project describes a due diligence analysis on a ‘green’-rated office building. The building was assumed to be a system consisting of envelope, services, occupants, economic and urban environment. A parametric differential sensitivity analysis tested the effects of short and long term changes.
