The main objective of this project is to provide and deploy a web-based survey tool that allows building stakeholders to assess the performance and success of the design of their space. This tool facilitates the acquisition of accurate and reliable feedback from the building occupants (i.e., the people who actually exist and interact with the space’s environment). This feedback creates an open-dialogue between the building’s occupants, managers, owners, etc.
In addition to the surveying tool, this project aims to provide users with an interacting reporting tool that allows decision makers to easily evaluate and identify problem areas and design solutions to improve occupant experience. Further, the reporting tool allows users to benchmark their space against similar buildings in one of the largest building databases in the world. These diagnostic compatibilities allow building stakeholders to make informed management decisions, and to assess the effectiveness of building features and design strategies.
Finally, this tool and report can also be used to fulfill requirements for a number of building certification programs (e.g., LEED).
Significance to Industry
While there has been considerable focus on measuring and regulating the resource efficiency of buildings, less attention has been paid to the issue of how well buildings meet their design intent for the occupants. Building occupants represent a wealth of information about how well a building actually works. The challenge is to collect and analyze this input in a systematic and meaningful manner.
This survey and interactive reporting tool allows designers, developers, owners, operators and tenants to objectively gauge how well building services and design features are working. This information is especially useful to building owners and tenants interested in optimizing environments that truly support an occupant’s goals and needs
CBE developed a web-based survey with an integrated, flexible branching structure, and automated, easy to understand interactive reporting tool. Its branching structure allows for the collection of more detailed data where appropriate, without burdening all survey respondents with overly detailed or inappropriate questions.
The current CBE survey focuses on seven areas of indoor environmental performance, including thermal comfort, air quality, acoustics, lighting, cleanliness, spatial layout, and office furnishings. It has been implemented in over 1,000 buildings to date, with over 100,000 individual occupant responses (as of March 2017). Additional survey modules have been created to gather data on additional topics such as security, accessibility, transportation, and green building features.
Survey results are viewed via an advanced interactive reporting tool. This reporting tool allows researchers, building owners, and design teams to view data to study specific questions and trends.
We are implementing the survey for a number of private and institutional clients on an on-going basis. At times we have focused mass deployments of surveys to study specific building types and features. For example, in the past we implemented a series of surveys in LEED buildings in order to study the relative IEQ performance of these building in comparison to other buildings in the survey database. Currently we are deploying surveys to a number of buildings with radiant systems to capture metrics on buildings with these systems and compare their IEQ performance to those buildings that do not have radiant systems. This is also allowing us to create the largest database of radiant buildings worldwide.
Top performing buildings that use the CBE survey are invited to participate in the annual Livable Buildings Awards, which showcase buildings that perform well in terms of sustainability, overall design, and occupant satisfaction.
