Towards policy for efficient buildings in Brazil

Addressing the challenge to improving building energy performance

Some work is already happening…

… but we have long way to go

The NDCs put pressure on the energy sector

Voluntary programs have played an important role

• Utilização da tecnologia BIM (Building Information

Modeling) no gerenciamento do projeto;

• Aproveitamento da iluminação natural.

There are still a number of fundamental challenges…

Fragmented market

Low awareness & visibility

Poor compliance levels

Lack of data

No coordinated activities

Split incentives and ownership

Different service levels

…but we are in a good position to start to address them

Limits on supply-side generation (cost and environmental)

Political visibility and willpower

Funding availability (Procel and ANEEL)

Range of experiences and test cases

>10 years of technical development

How do we get past the design and into implementation and feedback?

Key actions to overcome the challenges

What is happening and what is planned

Collect more data: get to know the building stock

HVAC market modelling and assessment – iCS/LBNL

PPH: survey on ownership and use of appliances – Procel

Commercial buildings consumption survey – EPE

Benchmarking database – CBCS

Inter-agency cooperation and planning

Simplify regulatory compliance

NBR 15.575

Standardise accounting and reporting

frameworks for:

Building codes

Subsidy programs

Voluntary certifications

Labelling programmes

Benchmarking and transparency

MEPs

Roll out energy labelling and minimum standards

Roll out energy labelling and minimum standards

Improve data management

Municipal governments can lead implementation

Implement building codes (more stringent than

national MEPs)

Incentivise sustainable buildings – property tax,

construction quotient, fees

Local transparency programmes

Efficiency in public buildings

Remove barriers to retrofit

Training and awareness

Cross-cutting studies are needed for support

Plan structured capacity building: Universities, technical colleges,

designers, facilities managers, regulators

Study comfort and indoor environmental quality in the context of

energy performance and occupant expectations

Start to address embodied energy of buildings as a key part of energy

performance

Create a culture of transparency around energy performance data

Develop and test models for financial incentives and subsidies for

efficient buildings (the carrots)

But the key challenges have started to be addressed

Fragmented market

Low awareness & visibility

Poor compliance levels

Lack of data

No coordinated activities

Split incentives and ownership

Different service levels

Apply a range of approaches

Market development

Staggered roll-out and capacity building

Targeted studies and data management

EE Action Plan and Procel aligned

Increase transparency of performance

Address building and equipment

Any questions?
