CHPS Changing the Game

Six marketing roundtable sessions

Objective 1: Create consensus on improvements to the CHPS program

Objective 2: Create consensus on how to move forward as an industry

CHPS Recommendation #1:

Use a Term That Has a Common

Meaning for Providers and Customers

• Permanent modular vs. temporary portable/ relocatable

• Prefabricated classroom

• Off-site built classroom


Provide Recognition Levels

• Provide some amount of additional recognition to superior projects

• Address quantitative and qualitative improvements

CHPS

CHPS Verified Leader - New Construction Example

• CA & TX New construction projects must earn minimum of 64 points - CO must earn 60 points – Claim at least 2 points in LEI and CL

– 5 points in SS, WE and ME

– 10 points in EE, and

– 12 points in EQ

New Buildings On Existing Campuses

• Major modernizations and new buildings on existing campuses must earn at least 50 points in CA, TX, 48 points in CO and 45 Points in MA

Recommendation #2:

Provide Recognition Levels


Address the Correct Audience

• CHPS can serve as a clearinghouse of information

• Address school owners and design professionals

• Look for key organizational partners


Education is Key

• Educate on the benefits

• Address cost as well as lifecycle analysis

• Need to educate both providers and customers


Make Responsibility for Each

Prereq/Credit Clear to Customer • Some prereqs and credits require

additional tasks by provider after siting

• These are different from tasks that must be completed by school owner

• CHPS should make this clear by making space on the scorecard for provider to show responsibility for completion


Certify a Base Model and Allow for

Add-ons or Other Models

• One of the main benefits of prefabricated buildings is customizability

• CHPS should allow for add-ons

CHPS

• More than 55 million children spend

their days in 133,000 schools in the

US

• Students attending schools in poor

condition score lower on

standardized tests than students

who attend schools in good

condition

• Nearly 6 out of 10 schools reported

at least one major building element

in disrepair

• ASCE Infrastructure Report Card

gave Schools a “D”

Why Existing Schools?

CHPS

• Most of the Schools of the Future

are Already Built

• Invest in High Performance Capital

Improvements and Save Your

General Fund Now and for the Life

of the School

• As soon as it’s built a new school

becomes an existing school

• That’s Where the Money is!

Why Existing Schools?

CHPS Operations Report Card

• A CHPS program for existing school buildings

• Assess current conditions and recommend improvements

• Recognize high-performance and high-improvement schools

• Web-enabled toolkit designed for district-wide deployment

• Engage a wide variety of school staff: – Maintenance staff

– Teachers and admins

– Students

– Principals or superintendents

Scored Categories

• Energy Efficiency

• Thermal Comfort

• Visual Comfort

• Indoor Air Quality

• Acoustics

CHPS Importance of Lighting Quality

• Quality natural daylight and high

performance electric lighting has

been found to increase performance

and productivity and increase

student test scores

• Reducing reliance on electric

lighting can reduce operating costs References:

CHPS Importance of Good Acoustics • Speech communication is an critical

part of the learning process

• As many as 1/3 of kids in typical

classrooms have extra sensitivity to

poor acoustics due to ESL, HOH, LD,

ADD, speech disabilities, and

relatively frequent colds

• Speech intelligibility research shows

that HOH kids lag peers in

educational achievement

• Intrusive noise distracts students;

high background noise can promote

problematic student-to-student

communication, negatively impacting

“classroom management”

CHPS Background Noise Level Fundamentals

Background Noise (35 dBA)

Speech 50 dBA (intelligible)

15 dB S/N Ratio

Importance of Good Acoustics

CHPS Elements of Indoor Air Quality (IAQ)

CHPS How to Assess and Score

• 100-point scale for each category

• Energy Efficiency – ENERGY STAR Portfolio Manager

• Auto-tracking of utility bills in some areas

• ENERGY STAR score will be the scorecard score

• IAQ, Acoustics, Thermal Comfort, and Visual Comfort – Occupant surveys

• Teachers and staff, no students

– Building assessment • General information

• Detailed sampling
