Overview
Governmental entities and private corporations in the United States and worldwide, face an enormous challenge to improve the performance of the built environment. The CO2 and energy reduction targets that are being discussed in pending legislation will require huge investments in the existing building stock over the next 25 years, whereas the performance targets for new buildings will far exceed current practices.

This OnDemand Webinar will help all directly and indirectly involved parties to set sensible targets and benchmarks, execute realistic performance improvement plans, and perform the design and retrofits that meet the challenges laid out above. It targets in particular the managers of corporate real estate portfolios, federal building managers, facility groups at university campuses, and building managers at city, state and federal level. The OnDemand Webinar is also specifically addressed at professionals in design, retrofit and auditing firms who want to understand the developments in building benchmarking, how to express and measure the various performance aspects, understand the relationship to energy standards and green rating methods, and conduct audits for verification.

Learning Objectives:
You will be able to discuss the emerging agenda of sustainable and high performance buildings.
You will be able to review data quality and consistency issues.
You will be able to identify industry wide benchmarking efforts.
You will be able to describe tools and methods for energy benchmarking.

Agenda

Why Benchmark Building Performance?

• The Emerging Agenda of Sustainable and High Performance Buildings
• Setting Performance Targets Related to Functional Requirements and Societal Benefits
• The Growing Importance of Energy Benchmarking: From Single Building to Large Scale Portfolios
• The Risk That Buildings Underperform: Design Intent and Realization
• Dealing With Uncertainties in Target Setting and Benchmarking

Benchmarking Strategies

• How: Normative vs. Simulation Based Methods
• What: Prescriptive vs. Performance Based Approaches
• When:

- In Design: Design Performance Benchmarks

- At Delivery: Building Commissioning

- During Operation: Audits and Retro-Commissioning

• Issues: Data Quality and Consistency
• The Need to Support Decision Making:

- Invest in High Performance?

- When to Retrofit?

Industry Wide Benchmarking Efforts

• Green Assessment Methods

- Available Systems Such as LEEDŽ

- Differences Across Methods

• Existing Benchmarks

- Energy Star

- Building Energy Quotient

- Industry Averages

- e-BIDS

- High Performance Building Database

- LEEDŽ Existing Buildings

• Other Performance Aspects

- Indoor Environmental Benchmarking: Thermal Comfort, Indoor Air Quality, Mold, VOC, Lighting, Acoustics, Water Consumption

• Occupant Satisfaction and Organizational Effectiveness Benchmarking: Post Occupancy Evaluation

Tools and Methods for Energy Benchmarking

• Energy Standards

- U.S. Approach ASHRAE 90.1

- European Approach: CEN-ISO

• Energy Audits and Continuous Energy Commissioning
• The Large Scale Retrofit Agenda: When Are Deep Audits and Submetering Required?
• Cost Benefit Analysis
• The Energy5D Approach to Large Scale Energy Benchmarking and Retrofit

Application Study

• Large Scale Energy Benchmarking: The Case of the UPenn Campus (170 Buildings)
