Key Messages to Accelerating Energy Efficiency in Buildings
Dr. Ksenia Petrichenko,
Copenhagen Centre on Energy Efficiency
Addressing barriers to EE in buildings
Key messages:
1. Importance of policy package2. Shift towards actual energy use3. High level of ambition4. Focus on enforcement5. Implementation work
Message 1: Policy Package to drive the change
Codes, standards, regulations, etc.
Green loans,Rebates,Taxes, etc
Voluntary schemes, Capacity building,
Awareness
Targets, roadmaps
Sticks Carrots Tambourines
There is no single policy, which can address all existing barriers EFFECTIVE POLICY PACKAGE is needed
Business models, private sector engagement

Global Map of Building Energy Codes
Policy development of building energy codes is continuing to
become more prevalent globally
GABC Global Status Report 2016: http://www.globalabc.org/
Standards - driver for energy savings
2020: all new residential to be NZE
2030: all new commercial buildings to be NZE
2025: all new state buildings and major retrofits to be NZE
2025: 50% of existing state-owned buildings to be retrofitted as NZE
2030: 50% of existing commercial buildings to be retrofitted as NZE

Message 2: Importance of actual energy use
Prescriptive
• Requirements on individual building components
Trade-off
• Specific rules on overall performance values typically to allow trade-offs between elements of the building envelope
Performance-
based
• Energy performance requirement for the whole building such as kWh/m2
Outcome-based
• Energy performance requirements for the actual energy use of a building demonstrated through the operation

Actual vs designed energy consumption
Monitoring designed and actual heat use of low-energy dwellings and the effect of user behaviour on the final energy demand

Efficient design versus efficient practices….
Based on 230.200 detached Danish houses with an energy label. Gram-Hansen and Hansen (2016)
Denmark
Rebound effect:in efficient buildings actual energy use is often higher than the theoretical one due to occupants' behaviour
Strategies:Recognition in policy design, standards & labeling, awareness raising, smart meters, consumer feedback & enhanced billing, benchmarking, identity signalling, positive examples
Message 3: High level of ambition
Step 1: reduce the need for space heating and cooling through building envelope measuresStep 2: reduce heating and cooling energy use through efficient HVAC systemsStep 3: integrate RE supply

Examples exist, but scale is small

Message 4: Focus on enforcement
IEA 2013. Policy Pathway - Modernising Building Energy Codes
• Certified inspection companies to analyze building architectural plans • Building license is granted after a positive compliance report review • Certified engineering inspection companies perform inspections during construction• Local quality supervision agency performs compliance checks during the building process• Random annual inspections through the Ministry of Housing• Occupancy permits issued only if buildings pass all compliance checks

Message 5: Engaging different levels of governance
Country
City
District
Building
National targets and policies to be translated into policies and actions at the city level
City-level targets and policies to drive the construction and renovation projects
City-level projects and initiatives to drive the policy change at the city and even national levels

Deep Dive Case Study: Mexico City
September 2014 commitment from Mexico City government to:
– Implement a building energy code
– Retrofit public buildings
Launch workshop for common vision: March 2015
– 100 multi-stakeholder participants – including city government, federal government, businesses, finance, civil society and consulting
Action plan underway: 4 workgroups chaired by Mexico City staff and an SEforALL partner, project managed by WRI
– Technical workshop on building retrofits and finance
– Recommendations on action by government and stakeholders delivered in October; Actions announced at COP 21 in December
– Program implementation phase 1: January 2016-October 2016
– June 2016: New energy code adopted; public building audits approved
– December 2016: Audits of 4 public buildings completed
– Ongoing: code implementation capacity building, retrofit finance,

Scaling up: work in deep dives
• Customised procedures for buildingretrofits
• Municipal building retrofit project
Bogota
• Adaptation and implementation of national regulation on construction
• Construction of a new private building
Eskişehir
• Implementation of energyperformance certification
• Energy efficiency into district-scaledevelopment projects
Da Nang
• Building efficiency standars and incentives
• Energy efficiency solutions for a hotel demo project Rajkot
• Implementation of India’s ECBC and requirement for solar HW systems
• Energy efficiency standards for social housing programs
