Latest: BEMA-CDS complete, report now available
The Building Energy Mapping and Analytics Concept Development Study (BEMA-CDS) scoped the current state of development of energy mapping and analytics, supporting characterizing energy end-use, efficiency and renewable energy technology integration opportunities in the built environment.
Building energy mapping and analytics are recognized as critical for geo-targeting energy policies, programs, codes, incentives, and technology integration to accelerate the transition to a low-carbon built environment and economy.
The scope of the CDS included undertaking to:
- Characterize the state of development of energy mapping and analytics in the building stock broadly; and
- Inform and propose IT architectural practices and standards to enable mapping and analytics of residential energy use and efficiency specifically.
Concept and Motivation
Over 400 Canadian municipalities have completed community energy and emissions plans for which they acquire data and conduct or procure modelling. Electric and natural gas utilities procure Conservation Potential Reviews (CPR) and establish Demand Side Management (DSM) programs to achieve energy conservation and efficiency targets in buildings. Nationally, Canadian federal government departments conduct surveys and building energy modelling to inform policy and program development, changes to equipment standards and energy performance requirements in the National Building Code.
Energy usage is derived from different sources and methods including measured energy demand data, modelled building simulation data; various statistical and aggregation techniques are applied inconsistently by different organizations to estimate current and projected end-use and efficiency opportunities. Although data are used by municipal, utility and federal government policies, programs and planning processes at different spatio-temporal resolutions, at a fundamental level, the data is essentially the same. What is required for all of these processes is an understanding of the building stock: the relevant characteristics of various building archetypes and their associated energy usage impacts.
Strategic policy, planning and program efforts of municipalities, utilities and federal policy, program, codes and standards that govern these processes are not, however, harmonized in terms of how to incorporate data, characterize the building stock, and evaluate energy usage efficiency opportunities. The lack of geospatial data coordination in particular results in duplication of effort, lost energy savings and lost opportunities for climate change mitigation and resilience. Access to and use of consistent, authoritative geospatial data on the building stock and its energy performance is a systemic challenge that no one organization can fix alone.
NRCan-CE-O is leading research called the Canadian Energy End-use Mapping (CEE Map) project. The project’s objective is “to help governments and utilities see housing energy end-use and efficiency opportunities on the map.” The project is funded by the Program of Energy Research and Development (PERD), the NRCan Innovation Fund and the GeoConnections Program. The CEE Map project will develop one or more online interactive mapping applications that will expose much-needed housing energy use and optimization data to non-building science professionals, in a format they can use. The CEE Map project builds upon and advances past NRCan, CE-O research on energy mapping and building-archetype applications. Experience gained, partnerships developed, and IP generated (eg. Integrated Community Energy Mapping (ICEM), which includes the SCEC3 model and TaNDM methodology), will inform both the CEE Map project and this OGC CDS.
Building Energy Scenarios
Three principal usage scenarios for building energy mapping and analytics were chosen to motivate the questions posed in the BEMA-CDS Request for Information (RFI). Other usage scenarios may also be relevant in the future.
1. Community Energy and Emissions Planning
2. Utility Conservation Potential Review & Demand Side Management Program Planning
3. Federal/Provincial/Territorial Building Energy – Policy Programs, standards, building codes
This graphic produced for the Tract and Neighbourhood Data Modelling (TaNDM) Project, which developed a new map-based methods for creating energy and emissions inventories with measured energy data aggregated by building type. The CEE Map project will draw on these methods, and apply them to the integration and aggregation of modelled building energy data.
