Architecture 2030Meeting the Challenge

Page 2: Arch 2030 Presentation

The 2030 Challenge

All new buildings, developments and major renovations shall be designed to meet a fossil fuel, GHG‐emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type.

60% in 201070% in 201580% in 202090% in 2025Carbon‐neutral in 2030 (using no fossil fuel GHG emitting energy to operate).

The 2030 Challenge

These targets may be accomplished by implementing innovative sustainable design strategies, generating on‐site renewable power and/or purchasing (20% maximum) renewable energy and/or certified renewable energy credits.

Envelope

Remember, code is the minimum allowed.  It won’t get you to your goal.

Instead, start with ASHRAE’s Advanced Energy Design Guides

Use energy modeling early to determine performance goals.

Climate zones change requirements.  Breckenridge is different than Denver.

Optimize window selections for orientations.

Look at new technologies.  SIPs, ICFs, etc.

Daylighting

At least they can’t say they don’t have anywindows.

Page 9: Arch 2030 Presentation

Daylighting

Building needs to be oriented properly.

Need to aggressively target the use of artificial lights.

Artificial lighting should be tied into daylighting, and should dim when conditions allow.

Windows need to a balance of thermal performance, solar performance, and visible light transmittance.

Direct light must be controlled!

Take advantage of the 300 days of sunshine a year in Colorado.

Mechanical

Efforts in envelope and daylighting should reduce mechanical systems sizes.

Look at innovative strategies: geoexchange, natural ventilation, evaporative cooling, energy recovery, chilled beams.

Integrate HVAC  with occupancy sensors.

Controls

Can improve efficiency of system, but won’t make up for lost efficiency in envelope, daylighting, or mechanical systems.Need to be flexible for future technologiesLook at systems that integrate all systems – lighting, mechanical, and schedules.

Dilemmas

Gas versus electric?Source Power:  Do we design for the now (coal burning plants), or for the future (renewable energy)?

Renewable energy sources – photovoltaic, wind.Supply has gone up, but so has demand (and cost).

Limited control of the building performance after turnover. Energy Star measures actual use. 

Increase the education of our building users.Include ongoing commissioning.

Final Thoughts

It reached the current (2008) goals of Architecture 2030.Need to monitor ongoing performance and compare to model.Projects started in the next two years will need to be even more efficient to meet the 2010 requirements.Eventually, we’ll need to include on‐site renewable energy (or purchase credits) to achieve the requirements.
