The 8th International Forum

on Energy for Sustainable Development

12 June 2017

Astana, Kazakhstan

Key Messages to Accelerating Energy Efficiency in Buildings

Dr. Ksenia Petrichenko,

Copenhagen Centre on Energy Efficiency

Page 2: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

Addressing barriers to EE in buildings

Page 3: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

Key messages:

1. Importance of policy package2. Shift towards actual energy use3. High level of ambition4. Focus on enforcement5. Implementation work

Page 4: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

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

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

Page 10: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

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

GABC Global Status Report 2016: http://www.globalabc.org/

Page 12: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

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

China

Page 13: Key Messages to Accelerating Energy Efficiency in Buildings · through building envelope measures Step 2: reduce heating and cooling energy use through efficient HVAC systems Step

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,
