Houston AIA is a Registered Provider with The American Institute of Architects Continuing Education Systems (AIA/CES). Credit(s) earned on completion of this program will be reported to AIA/CES for AIA members. Certificates of Completion for both AIA members and non-AIA members are available upon request.

This program is registered with AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material or product.

Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation.

The construction and operation of buildings accounts for almost 50% of the United States greenhouse gas emissions. But reusing and retrofitting our

existing buildings can reduce these emissions dramatically. Reusing what we have – buildings, landscapes and communities – is the best way to make the

biggest, most immediate impact in controlling climate change. New construction and major renovation comprises less than 10% of the country’s

real estate portfolio, so it is clear that making a substantial impact on our planet will require focusing on the greater than 90% of buildings that are not new. While older, traditional buildings use less energy on average than more

recent buildings, some worry that a push to green historic buildings will threaten valuable cultural resources.

Greening What’s Already Here

Learning ObjectivesAt the end of this program, participants will be able to:

1. Demonstrate how original character defining features in existing and historic

buildings can be reactivated to improve energy and resource efficiency.

2. Identify the cultural and preservation metrics in past, current and future

versions of the LEED rating system and how the recognition and use of

these metrics has been improving.

3. Discuss the importance of greening the operations of existing and historic

buildings.

4. Review the difference between LEED capital products and the LEED

operations and maintenance product, and why the maintenance product will

have a more significant impact on world resource use.

Climate Regions


Building reuse typically offers greater environmental savings than demolition and new construction.

It can take between 10 to 80 years for a new energy efficient building to overcome, through efficient operations, the climate change impacts created by its construction.

The majority of building types in different climates will take between 20-30 years to compensate for the initial carbon impacts from construction

Reuse Matters


The environmental benefits of reuse are maximized by minimizing the input of new construction materials.

Renovation projects that require many new materials can reduce or even negate the benefits of reuse.

Cliveden - Passive Approaches for Improved Environmental Control

• Separate humans from collections– Relocate offices out of the Main House– Relocate collections storage out of the Main

House

• Improve envelope performance– Reduce water penetration and humidity at

basement– Reduce air infiltration– Insulate and seal attic

• Replace attic insulation

• Refurbish site drainage to reduce water penetration at basement

Cliveden - Low Tech Improvements

Cliveden - New HVAC System

• Replace gas-fired boiler in Wash House

• Replace basement air handler

• Control heat by humidistat--maintain winter humidity levels above 25%, with steam humidifier back-up

• Cooling coil at the air handler to maintain summer humidity level below 70%

• Air circulation from basement to attic w/ returns in new air shafts and lined chimneys

• New chiller behind Wash House sized for future air conditioning in tenant spaces

Why Would an 1886 House Museum Care About LEED?

Sustainability Goals

1. The Haas-Lilienthal House is a symbol of San Francisco Architectural Heritage and “Heritage” would like to expand this symbol of the organization to act as a model of sustainable preservation.

2. “Heritage” intends to “green” the Haas-Lilienthal House to improve the resource use of the site, broaden the audience of the organization and to prove the relevance that a house museum can continue to have in our culture.

Sustainability Goals

Assess

• Analyze current physical assets

• Determine areas for improvement

• Set realistic goals• Establish measurable

objectives• Select LEED strategies
