2 a mental image: CONCEPT

3 a sensation interpreted in the light of experience




Architecture has evolved

from a necessity

to an art form

to a business tool

Learn how to work with your architect

to achieve projects of greater value


Six Goals that Determine the Value of a Project

1. Reduce Construction Costs

2. Reduce Operation & Maintenance Costs

3. Increase Productivity of Occupants

4. Reduce Energy Costs

5. Shorten Construction Schedule

6. Increase the Return on your Investment

All 6 goals can be achieved while maintaining high aesthetic design standards and meeting or beating time constraints


Achieving the 6 Goals Impacts 10 Areas of Design

1. Siting

2. Waste Management

3. Materials Selection

4. Energy Efficiency

5. Renewable Energy

6. Indoor Air Quality

7. Landscaping

8. Exterior/Building Design

9. Water Conservation

10. Water Quality


Goal 1:

Reduce Construction Costs


Waste Management

Materials Selection

Energy Efficiency


Rehabilitate an existing site

Reuse/renovate existing structure

Salvage materials for reuse/resale

Use salvaged/refurbished materials

Factory finishes over site finishing

Concrete rubble as sub-base fill for pavement

Fly ash or blast furnace slag in cement

Use natural ventilation and passive energy design for heating and cooling

Install waste heat recovery system to preheat air or water

Eliminate permanent irrigation systems


Case Study

  • Pacific Place Shopping Mall
  • Seattle, Washington
  • Developing a comprehensive Construction
  • Waste Management Plan achieved:
  • 10,798 tons of concrete hauled offsite for recycling
  • 1,157 tons of scrap iron and metal sold
  • 12,034 tons of concrete crushed and reused for another project
  • 764 tons of wood recycled to paper pulp
  • Savings from tipping fees and monies from salvage were calculated at $140,000.

Goal 2:

Reduce Operation & Maintenance Costs


Waste Management

Materials Selection

Indoor Air Quality


Use light-colored, low-albedo finishes

Provide recycling facilities for building occupants

Select finishes for ease of maintenance

Use a permanent monitoring system

Design entryway to prevent contamination

Use indigenous plantings

Cluster plantings

Eliminate permanent irrigation systems


Goal 2:

Reduce Operation & Maintenance Costs


Exterior/Building Design

Water Quality

Water Conservation

Shade impermeable surfaces

Implement on-site biological waste water treatment

Specify water conserving fixtures

Use gray water system

Use water conserving cooling towers

Implement water efficient landscaping


Case Study

  • Southern California Gas Company’s
  • Energy Resource Center
  • Energy Resource Center (ERC) provides:
  • Recycling bin for cardboard & office paper
  • Kitchen bins for cans, glass, & plastic
  • Recycling containers in every workspace
  • These programs recycle approximately 2 tons of materials monthly for a cost savings to ERC operations of $36,000.00 annually

Goal 3:

Increasing Productivity


Materials Selection

Energy Efficiency

Indoor Air Quality

Exterior/Building Design

Water Quality

Orient buildings to capture natural light

Limit volatile organic compounds (VOC)

Allow tenants individual control over light and air

Use of daylight

Maintain high indoor air quality standards

Limit VOC’s, dust/debris, bacterial growth

Use of light shelves and shading devices

Keep views to the exterior open

Provide water filtration system for drinking water


Case Study

  • Southern California Gas Company’s
  • Energy Resource Center
  • The Energy Resource Center (ERC) has implemented an approach to indoor air quality addressing four basic factors:
  • HVAC design & operating considerations
  • HVAC pathways kept from contamination sources
  • Activities performed by the facilities occupants
  • Implemented a strict “No Smoking” policy
  • ERC staff averaged 14.57 “sick” hours /employee vs.. 16.27 “sick” hours/employee for field staff and 21.38 “sick” hours/employee for the company wide management training group

Case Study

  • Herman Miller
  • SQA Building
  • Three key concepts guided the design for this building:
  • Occupant comfort, health, & communications
  • Exterior/Interior environment integration
  • Use of natural daylighting
  • As a result of these design concepts, worker effectiveness rose from 98.54% to 99.53% and work quality rose from 98.97% to 99.23%

Comparison Between

Window Proximity & Health Complaints


Goal 4:

Reduce Energy Costs

Energy Efficiency

Renewable Energy


Exterior/Building Design

Use fluorescent fixtures in lieu of incandescent

Use lighting sensors

Natural ventilation for cooling

Use a waste heat recovery system

Use integrated renewable energy sources

Use “net metering”

Energy modeling

Shade western facades

Utilize tree lines to direct airflow

Use sun-shading devices and light shelves

Optimize building insulation

Optimize glazing


Case Study

  • Herman Miller
  • SQA Building
  • Extensive use of natural light:
  • Use of windows and clerestory oriented to the south for maximum solar gain
  • Use of light shelves
  • Use of Highly efficient light fixtures
  • Use of dimmable light controls with sensors
  • As a result annual energy savings are calculated at $35,000.00.

Case Study

Herman Miller

SQA Building

Electrical and mechanical systems were designed

for maximum efficiency

Use passive solar heating and natural ventilation for thermal comfort

As a result natural gas costs have decreased 7% and electric costs have decreased 18%


Goal 5:

Shorten Construction Schedule


Waste Management

Materials Selection


Rehabilitate an existing site

Reuse/renovate an existing structure

Use of locally manufactured materials

Use of indigenous plantings


Case Study

  • Herman Miller
  • SQA Building
  • Use of building materials produced locally
  • Use of landscape plantings indigenous to the area
  • As a result, the 295,000 square foot building was constructed in only 18 months

Goal 6:

Increasing Return on Investment


Exterior/Building Design

Provide transit and pedestrian links to mass transit

Design with future resale in mind


Case Study

Offices for Gap Inc.

San Bruno, California

This building was designed to be reused as either commercial space, or a residential complex. Slab to slab clearances are held at 12 feet instead of 10 feet, and a modular plan for ease of reconfiguration to apartments.



You may have noticed that these efficiency gains are an

outgrowth of environmentally sustainable design.

This is no coincidence.

Sustainable design yields benefits to your bottom line

while increasing the goodwill your business enjoys locally

and globally.

A survey of architects suggests that they are knowledgeable

of sustainable design principles and ready to provide these

services to their clients.

The next time you speak with an architect, consider the

value of environmentally sustainable design services.
