Building Perfomance

Question 1

Define the term “Carbon Neutrality”.

Answer 1

Refers to the state of having a net-zero carbon footprint. This means that the amount of carbon dioxide (CO2) emissions released into the atmosphere is balanced by an equivalent amount of CO2 removed from the atmosphere or offset through various measures.

Can be done in the built environemtn by drcreasing the energy demand.

Question 2

How is “Monitoring” of building performance defined. Provide key examples of requirements for building performance monitoring

Answer 2

Monitoring of building performance refers to the evaluation of how well a service or system perform. Monitoring makes it possible to improve energy efficiency and find issues before the damage is done.

Question 3

Define the term “Performance Gap” as relevant to buildings.

Answer 3

Performance gap is when the predicted performance (ex by simulations) sont match with the measured in use performance. This can happen due to many things, for an example wrong or inaccurate design values, construction errors or maintenance failure

Question 4

What problems can the building performance gap result in?

Answer 4

Papperssvar

Question 5

What is the “Data Gap” as relevant to buildings. What are the key causes for the building data gap?

Answer 5

• In most buildings, we lack quality assured data on key aspects of building
  performance,
• We typically do not plan (from the earliest project phases) for adequately measuring
  and controlling building performance over the building’s lifetime,
• There is no unified or standardized approach to collecting data on building
  performance,
• There is no unified or standardized approach to comparing or benchmarking key
  aspects of building performance,
• In most cases, there is no mandatory requirement for (continuous, real-time or
  human-centric) data-driven building performance management.

Question 6

What is the Smart Readiness Indicator and what is its purpose?

Answer 6

The Smart readiness indicator (SRI) is a common EU scheme for rating the smart readiness of buildings. The Smart Readiness Indicator is set to be an instrument for the qualitative assessment of buildings’ technological readiness. It’s meant to encourage using smart building tech and help Europe’s buildings become more eco-friendly. At the same time, it wants to make sure people using the buildings are happy and healthy.

Question 7

Describe the three key types (=categories) of Quality Management Services in buildings.

Answer 7

Technical Monitoring, TMon
* Digital monitoring of data (measurable performance)

Building Commissioning Process, Cx
* Monitoring that requires more expert & on-site work e.g. life-cycle costs calculation, O&M documentation etc.

Green certification, LEED, DGNB, BREEAM, HQE
* The wide setup of “green” requirements and assessment if they´re met.

Question 8

Describe key advantages of good monitoring and performance analysis in buildings.

Answer 8

• Improved ability to deliver user-adapted and cost-efficient system solutions for
  newbuild and retrofitting projects; more efficient production,
• Better adaptation of building design and function for specific user needs,
• Improved indoor climate and energy modeling, decreasing the gaps between
  simulated and measured/perceived performance ,
• More efficient (real-time, continuous) building commissioning,
• Higher user satisfaction and well-being, higher productivity and profitability; better conditions for contracting and delivery of user-adapted services,
• Digitalization of building performance management (big data, IOT, cloud-services, advanced
  automation tools, AI) – smart/intelligent buildings
