Case Study of Maple Hills - Costs & Benefits of
addressing both Sustainability and Public Health in
the Design of Communities
OVERVIEW
Built in 1972, the Steiner
Apartments buildings
were determined by
Physical Needs
Assessment reports to
have such significant
design, systems, and
structural deficiencies
such that they were not
economical to renovate.
VISION
 Demolish the run down-challenging Steiner Homes & Replace
with a new 48 unit apartment complex in the Avondale
Neighborhood in Chattanooga.
 Provide High-Quality Affordable housing with market rate
amenities including dishwasher, washer and dryer, and
refrigerator.
 Design and construction to assure quality & durability & to
maximize building lifetime & minimize maintenance.
 “LEED for Homes” Gold Certification, providing healthy,
affordable, green homes include ENERGY STAR appliances &
lighting, High-Efficiency water fixtures, heating & cooling systems
& energy efficient windows & doors and security system.
 Provide new residents a new sense of community at Maple Hills
for the families of Avondale.

INVOLVEMENT
• Public housing and community
residents and stakeholders met to
identify the strengths and
challenges of the Maple Hills
development during Fall-Winter
2010
• The Development Team met with
the Mayor and planning
departments to gain
recommendations
• Comments were incorporated into
a single plan, which became the
concept for the Maple Hills
redevelopment plan

SUSTAINABLE – BENEFITS
 IMPROVED PERFORMANCE & EFFICIENCY
 HEALTHIER INDOOR AIR QUALITY
 DURABILITY AND LONGER PRODUCT LIFE LOWERING
OPERATIONAL COSTS
 LOWER UTILITY COSTS FOR FAMILIES (25-50%) MAKING
UNITS TRULY AFFORDABLE
 HIGHER DEMAND FOR APARTMENTS & INCREASED
RETENTION
 COMMUNITY BENEFITS FROM LESS ENERGY USAGE
Integrated Design & Construction = Higher Performance for Minimal Premium
 Projects of this scope cannot be successfully accomplished without
SUMMARY
strong ties to the community, and the key to the success for the entire
effort were the partnerships in every facet of the development.
 The partnerships we developed allowed us to develop LEED GOLD
affordable housing without significant increases in costs.
 Provide a safe, high quality, durable and affordable development for
our community.
Together, we produced a new revitalized community in
Chattanooga as a the result of the collective vision of the
City, CHA, the Development Team, our residents and
committed community partners.

What is Green
Building?
Green Buildings are structures that
are cost effectively designed, built, and
operated in a manner that considers the
following elements:
•Energy Efficiency
•Healthy Indoor Air Quality
•Resource Efficiency
•Land Use and Site Issues
•Materials
•Equipment
•Education and Knowledge
Sharing
How does green design
happen?
• Mindset – Design team is motivated to
produce a green building
• Process – integrated design, all parties
engaged
• Tools – Metrics, benchmarks, modeling
programs
• Techniques / Products
United States buildings produce:
•
72% of electricity consumption,
•
39% of energy use,
•
38% of all carbon dioxide (CO2) emissions,
•
40% of raw materials use,
•
30% of waste output (136 million tons annually), and
•
14% of potable water consumption.
Source: Environmental Information Administration (2008). EIA Annual Energy Outlook. Water
Consumption from US Geological Survey--2000 data.
What are the benefits?
Environmental benefits:
* Enhance and protect ecosystems and biodiversity
* Improve air and water quality
* Reduce solid waste
* Conserve natural resources
Economic benefits:
* Reduce operating costs
* Enhance asset value and profits
* Improve employee productivity and satisfaction
* Optimize life-cycle economic performance
Health and community benefits:
* Improve air, thermal and acoustic environments
* Enhance occupant comfort and health
* Minimize strain on local infrastructure
* Contribute to overall quality of life
Doesn’t It Cost More?
•It depends on what it is being compared to.
•The implementation of many green features costs
less than other alternatives.
•Affordable residential building should cost no more
than 1-3% in additional construction costs for very
high energy and resource efficiency.
•Costs go down with integrated design and
experience.
•Energy savings, health benefits and community
wealth are unending to the occupants or users.
Building Materials
•Use durable products and materials.
•Choose low maintenance building materials.
•Buy locally whenever possible.
•Choose building materials with low embodied energy.
•Use building products from recycled and salvaged
materials whenever possible.
•Use responsible wood products whenever possible.
•Minimize use of pressure treated lumber.
•Minimize packaging waste.
Resource Efficiency
•Install water-efficient equipment, such as water saving
toilets, shower heads and faucet aerators.
•Value engineer all internal systems for ways to reduce
material use.
•Design water-efficient low maintenance landscaping.
•Design for durability and adaptability.
•Reduce construction waste.
HVAC Equipment
•Ground Source Heat Pump Beyond
•Split System Ductless
•Offset Registers
•Chill Beams
Healthy Indoor Air Quality
•Ensure the building has proper air exchanges
and pressures throughout.
•Eliminate unwanted leakages from places like
garages, crawl spaces and attics.
•Reduce use of toxic materials in building
interiors through the use of low VOC paints,
sealants and finishes.
•Avoid moisture problems, which lead to mold
and mildew growth.
