Training Objective for Building Module
Provide par+cipants withthe tools needed to create a
policy acFon plan forbuilding efficiency, through:
• Review of building efficiency policytypes
• In‐depth review of select policies,including examples
• Discussions based on your experiences
• Steps needed to design and implementbuilding efficiency policies
• On‐line resources, described in thepresenta+ons and hand‐outs

What is building energy efficiency?
Building Energy Efficiency(technical definiFon)
• The extent to which the energyconsump+on per m2 of floor area of the
building measures up to establishedenergy consump+on benchmarks for thatpar+cular type of building under definedclima+c condi+ons
Building energy consumpFon
benchmarks
• Representa+ve values for commonbuilding types against which a building’sactual performance can be compared

Why do we want building efficiency?
Buildings consume 40% of global energy
Many benefits
• Cheaper and faster than increasing energy supply
• Improved comfort
• Energy security
• Poverty allevia+on
• Job crea+on
• Improved produc+vity
• Environmental benefits

Why do we need building efficiency policies?
Many market barriers to efficiency
• Informa+onal
• Ins+tu+onal
• Behavioral
• Economic
To address so many barriers, needcomprehensive set of policies
But policy barriers exist too
• Although can draw lessons from like markets,local markets require local solu+ons
• Efficiency is hard to measure; requiresconsistent and credible data

Building Codes
• Prescrip+ve (minimum performance requirements for
building components; limited flexibility, easy to follow)
• Performance (maximum energy consump+on for wholebuilding; more economically efficient; more innova+ons)
Examples
• Effec+ve if enforced, addresses many barriersPros
• Enforcement, workforce training, mo+va+ngcompliance, can be highly poli+cal, largely ignores
exis+ng buildings
Keychallenges
• Base codes on 30‐year least lifecycle cost
• Increase market for low‐ and zero‐energy homes
• Require renova+ons to meet new codes

Incentives
• Reduce upfront costs: grants, tax credits, subsidies
• Improve access to financing: loans, interest rate buy‐
down, energy performance contracts, PACE
• Address split incen+ves: green leases
• Non‐financial: recogni+on programs, expedited permi]ng,
dispensa+on from other codes (e.g., height restric+ons)
Examples
• Cost o_en key barrier; works well in policycombina+ons
Pros
• Possible budget expense
Keychallenge
• Energy performance contracts
• Remove fiscal disincen+ves (e.g., fuel cost taxdeduc+ons)

Information Programs
• Awareness Raising: pilot programs; demonstra+on sites;
mandatory audits; public adver+sements
• Labeling and Cer+fica+on: building energy performancedisclosure; commissioning; high‐performance labels;
benchmarking
Examples
• Reach large audience; addresses new and exis+ngbuilding stockPros
• Improved informa+on ≠ ac+on; audit quality;
cer+fica+on is building‐specific
Key
challenges• Require efficiency audit and ra+ng (e.g., EU Building Pass)
• Encourage or require commissioning of new buildings
• Raise awareness of the value of dedicated energy
managers

Trainings and Capacity Building
• Efficiency included in basic building‐related curricula
• Trainings for standard se]ng, code enforcement,audits, data collec+on and evalua+on, buildingenergy management, integrated building design, and
financing op+ons
Human CapacityBuilding
examples
• Crea+on of energy agencies to implement
efficiency programs
InsFtuFonalCapacity Building
example
• Addresses a key barrier in many countriesPros
• Can be complex and +me‐consumingKey challenge
• Train and accredit building design and construc+on
specialists in integrated building systems
• Create networks of experts; provide training & webinars
• Train and deploy outreach agents

Public Leadership Programs
• Stronger codes for public buildings
• Efficiency goals & requirements to track and reportprogress
• Training and technical assistance for building managers
• Energy performance contrac+ng
Examples
• Large poten+al for energy savings and markettransforma+on, par+cularly for ESCOs; cost‐effec+ve use of public money
Pros
• Training building managers, ESCO capacityKey
challenge
• Ins+tute aggressive efficiency standards forgovernment buildings
• Expand the capacity for sub‐na+onal public agencies

Policy Combinations
Policy porolios—more valuethan the individual measurescombined
• Policies reinforce each other
• Market barriers are mul+ple—needmul+ple policies to overcome even one barrier
Examples• Mandatory audits & capacity building for auditors & financial
incen+ves (rebates, ESCO financing…)
• Labeling & financial incen+ves
• Building codes and subsidies or awards
• Public leadership programs and policies to support energyperformance contracts

Policy Combinations: IEA Recommendations
14
Among IEA’s 25 efficiency recommendations, 5 addressbuildings:
1. Mandatory and strengthened building codes for newbuildings
2. Support for passive energy houses and zero energybuildings
3. Incentives to retrofit existing buildings
4. Share information through building certificates
5.
Improved standards for windows and other glazedareas

Discussion Questions
What building policies do you want tolearn more about?
Which policies (1‐2) are the easiest toimplement in your country and would haveapplicability throughout the region?
Which policies (1‐2) offer the most cost‐effec+ve energy savings in your countryand could apply elsewhere in the region?
