Building Performance Management Flashcards
How is “Monitoring” of building performance defined. Provide key examples of requirements
for building performance monitoring
Monitoring, or technical monitoring (Tmon) is the measurement, assessment and analysis of a buildings or its subsystems compliance with predicted, legislated, contracted, standardized or otherwise required aspects and levels of building performance.
Examples:
* Indoor environmental quality (thermal environment, air quality, lighting environment, acoustics)
* Energy Performance (energy & power use, use of renewable resources)
* Occupant satisfaction (PPD, PMV, APD, AMV)
* Economic performance (project income, ROI, cash flow, operational cost)
Define the term “Performance Gap” as relevant to buildings.
Non-compliance with predicted, contracted or otherwise required aspects and levels of building performance.
What problems can the building performance gap result in?
Performance gap can result in problems such as:
* Excessive energy use
* Excessive emissions of carbon and other greenhouse gases
* Increased maintenance and operational cost
* Operation start-up loss
* Sub-par quality of building function and services
But also:
* Unsatisfactory indoor environmental quality
* Mismatch with business case
* Facility not meeting regulatory requirements
What is the “Data Gap” as relevant to buildings. What are the key causes for the building
data gap?
In most buildings, we lack quality assured data on key aspects of buidling performance. We typically do not plan (from early project phase) for adequately measuring building performance over the buildings lifetime. There are no standardized approach to measuring building perf. and there is no standardized approach to comparing or benchmarking key apsects fo building perf. There is also no mandatory requirement for data-driven buidling performance management.
Describe the three key types (=categories) of Quality Management Services in buildings.
Tmon (technical monitoring)
Building Comissioning Process (Cx)
Green certification, LEED, DNGB, BREEAM, HQE
Technical monitoring is data-driven testing of system performance. Technical monitoring gives better compliance with contractual or legal building performance requirements, since continuous measurments are made to meet the agreed upon target values (by owners/investors and third party service providers.
Building commissioning is a systematic process that ensures a building’s systems are designed, installed, tested, operated, and maintained according to the owner’s requirements and the building’s design specifications. It involves verifying and documenting that all of the systems and components in a building are functioning as intended.
Green certification: Green building certification involves a formal recognition that a building or construction project meets certain environmental and sustainability standards. These certifications are awarded by third-party organizations based on comprehensive assessments of various aspects of the building’s design, construction, operation, and maintenance.
Describe key advantages of good monitoring and performance analysis in buildings.
- Better Compliance with legislated or contracted build. perf. req.
- Energy efficiency due to better control of HVAC-operation
*Cost Savings - Data-Driven decision making
- Better understanding of building performance
- Improved indoor Climate
- Higher user satisfaction and well-being
*Digitalization of building performance management
What is a “Smart Building” according to IEA ERC Annex 81?
A Smart Building is a building that adaptively responds to changing conditions to maintain a comfortable indoor environment, and promote health, well-being and productivity of its occupants.
What is a “Data-driven Smart Building” according to IEA ERC Annex 81?
A Data-Driven Smart Building: specific category of Smart Building that actively applies live and historical data from sensors, IoT equipment, or any other data sources in order to achieve its targets.
Describe key challenges to utilizing smart technologies in buildings.
- Implementing occupant centric performance management and operation in times of energy/power shortage/crisis
