Architecture has evolved

from a necessity

to an art form

to a business tool

Learn how to work with your architectto 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

Rehabilitate an existing site

Reuse/renovate existing structureSalvage materials for reuse/resale

Use salvaged/refurbished materials Factory finishes over site finishingConcrete rubble as sub-base fill for pavementFly ash or blast furnace slag in cement

Use natural ventilation and passive energy design for heating and coolingInstall waste heat recovery system to preheat air or water

Eliminate permanent irrigation systems

Case Study

Pacific Place Shopping MallSeattle, Washington

Developing a comprehensive ConstructionWaste 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

Use light-colored, low-albedo finishes

Provide recycling facilities for building occupants

Select finishes for ease of maintenance

Use a permanent monitoring systemDesign entryway to prevent contamination

Use indigenous plantingsCluster plantingsEliminate permanent irrigation systems

Goal 2:Reduce Operation & Maintenance Costs

Case Study

Southern California Gas Company’sEnergy 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

Energy Resource Center

Goal 3:Increasing Productivity

Orient buildings to capture natural light

Limit volatile organic compounds (VOC)

Allow tenants individual control over light and airUse of daylight

Maintain high indoor air quality standardsLimit VOC’s, dust/debris, bacterial growth

Use of light shelves and shading devicesKeep views to the exterior open

Provide water filtration system for drinking water

Case Study

Southern California Gas Company’sEnergy 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 MillerSQA 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%

Goal 4:Reduce Energy Costs

Use fluorescent fixtures in lieu of incandescent Use lighting sensorsNatural ventilation for coolingUse a waste heat recovery system

Use integrated renewable energy sourcesUse “net metering”Energy modeling

Shade western facadesUtilize tree lines to direct airflow

Use sun-shading devices and light shelvesOptimize building insulationOptimize glazing

Energy Efficiency

Renewable Energy

Landscaping

Exterior/Building Design

Case Study

Herman MillerSQA 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 MillerSQA Building

Electrical and mechanical systems were designedfor 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

Rehabilitate an existing site

Reuse/renovate an existing structure

Use of locally manufactured materials

Use of indigenous plantings

Siting

Waste Management

Materials Selection

Landscaping

Case Study

Herman MillerSQA 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

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.

Conclusion:

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 linewhile increasing the goodwill your business enjoys locallyand globally.

A survey of architects suggests that they are knowledgeableof sustainable design principles and ready to provide these services to their clients.

The next time you speak with an architect, consider thevalue of environmentally sustainable design services.
