JELD-WEN Products Support UC Davis Team

Solar Decathlon 2017

Students build solar-powered homes to promote clean energy awarenessThe Solar Decathlon i s a compet i t ion sponsored by the U.S . Depar tment of Energy.

Co l lege s tudent s are cha l lenged to des ign and bui ld fu l l - s ize, so lar-powered homes .

Student s can then take what they have learned f rom the exper ience and app ly i t in the

rea l wor ld as they s tudy to become engineer s , arch i tec t s , des igner s or other profes s iona ls .

J ELD -WEN sponsored the Univer s i t y of Ca l i fo rn ia (UC) Dav is team, prov id ing windows and

door s to bui ld the i r so lar-powered, drought- ready home. Th is was the second t ime UC Dav is

competed in the event .

Why is i t cal led a decathlon?

Houses are judged on overa l l des ign, innovat ion, energy and water ef f i c ienc y, s t ruc tura l

des ign and more. There are 10 areas of judging, each wor th 10 0 po int s :

• Architecture

• Market Potential (including choosing a target market)

• Engineering

• Innovation

• Communications (community outreach and engagement)

• Water

• Health and Comfort

• Appliances

HISTORY OF THE SOLAR DECATHLON

The So lar Decath lon launched in 20 02 and has occur red b iennia l l y s ince 20 05.

The 2017 event was he ld in Denver, Co lorado, and inc luded teams f rom U.S . and

internat iona l schoo ls .

The U.S . Depar tment of Energy cons ider s the So lar Decath lon one of i t s mos t success fu l

out reach ef for t s . The event br ings awareness to c lean energy and sus ta inab i l i t y top ic s

in an engaging, rea l -wor ld manner. I t a l so emphas izes the comfor t and cos t sav ings

as soc iated wi th an ef f i c ient home.

The event has s ince expanded out s ide the U.S . w i th compet i t ions in Europe, China,

L at in Amer ica and the Middle Eas t .

To be cons idered for the compet i t ion, co l lege teams of facu l t y member s and s tudent s

submit proposa ls and p lans . These are eva luated by engineer s , s c ient i s t s and bui ld ing

exper t s , and spec i f i c c r i te r ia mus t be met to qua l i f y. The proposa ls are rated on four

ab i l i t i e s : to des ign and bui ld an ent i re l y so lar-powered house; to ra i se funds; to suppor t

the pro jec t through integrated cur r i cu la; and to as semble a team to execute the bui ld .

Scor ing in these four areas i s combined wi th the eva luat ions of the profes s iona l board

to determine which teams are asked to par t i c ipate.

MARKET STRATEGY

A s par t of the compet i t ion, teams determined a target market for the i r house. UC Dav is ’ Our H 2Ouse (pronounced

“Our House”) targeted Sacramento (urban) and Yo lo (rura l ) count ies , t wo areas ver y focused on increas ing water

and energy ef f i c ienc y.

In addi t ion, the home’s adaptab le f loor p lan and mix of indus t r ia l and modern rus t i c s t y les added to i t s market

appea l . I t was intent iona l l y des igned to be an eco -f r iend ly and af fordab le home.

Designing and buildingTeams t yp ica l l y spend t wo year s des igning and bui ld ing homes! E x tens i ve

tes t ing goes into the cons t ruc t ion to ensure that i t max imizes ef f i c ienc ies .

So lar energy mus t be the so le source of energy, ab le to power l ight ing,

run app l iances , mainta in temperatures and much more.

INSP IRAT IONS AND DES IGN PH ILOSOPHY

Our H2Ouse is a zero net energy (ZNE) house designed

for drought condit ions, something many Californians

encounter. Our H 2Ouse can cut t yp ica l - res idence

water use in ha l f whi le mainta in ing comfor t and

af fordab i l i t y.

The team cited the UC Davis West Vil lage apartment

complex, the largest planned ZNE community in

the U.S., as a major inspiration. They also looked

at the 2015 UC Davis Solar Decathlon entry,

the “Aggie Sol” project.

The UC Dav is team de l i vered a whole -house

concept that he lps res ident s form bet ter l i v ing

hab i t s , which reduces unnecessar y water use.

The des ign makes i t easier for homeowners to cut

their water consumption through moni tor ing, user

feedback and water rec lamat ion.

J ELD -WEN donated windows, pat io

door s and inter io r door s to the UC

Dav is team, inc lud ing:

• EpicVue® clad-wood casement windows

• EpicVue clad-wood awning windows

• EpicVue clad-wood sliding door

• EpicVue clad-wood outswing patio door

• MODA™ Collection solid core interior doors

Choos ing the mos t energy- ef f i c ient

w indows and door s was c r i t i ca l for

the team. They carefu l l y cons idered

s ize and p lacement when draf t ing

the i r f loorp lan. Windows and door s

a l so impac ted the l ight ing des ign,

compet i t ion tour route and inter io r-

ex ter io r connec t ions of the house.

The story of windows and doors

WINDOWS

They chose Ep icVue windows for the i r energy - ef f i c ient

at t r ibutes such as Low- E 366 g las s and the i r s imple,

e legant des ign. The Ep icVue produc t s a l so made the inter io r

and ex ter io r connec t ion seamless . Th is gave the house the

i l lus ion of be ing b igger.

The windows a lso had favorab le so lar heat ga in coef f i c ient

(SHGC) number s . The SHGC is the f rac t ion of inc ident

so lar rad iat ion admit ted through a w indow, both d i rec t l y

t ransmit ted and absorbed then subsequent l y re leased inward.

The number ranges bet ween zero and one; the smal le r the

number, the les s so lar heat t ransmit ted.

The windows a lso met U -fac tor va lues . U -fac tor i s the

amount of heat f low through a produc t . The lower the

number, the more energy ef f i c ient the produc t i s .

The casement and awning windows c i rcu late a i r

throughout the space. Th is reduces the need for other

coo l ing equipment .

INTER IOR DOORS

The MODA Col lec t ion door s used featured three so l id pane ls

pr imed and ready to pa int . MODA door s feature a P roCore ®

So l id Core, which reduces sound t ransmis s ion by up to 50

percent compared to a ho l low door. Th is core a l so he lps

res i s t the dent s and d ings of normal usage. The team c i ted

the weight of the MODA door s as another fac tor in the i r

se lec t ion. A heav ier door i s of ten cons idered to be of h igher

qua l i t y. The team chose Swiss Cof fee , an of f-whi te co lor,

to f in i sh the inter io r door s .

EXTER IOR DOORS

The team was de l ighted wi th how the ex ter io r door s c leanly

integrated into the bui ld ing enve lope. Team member Geof f rey

Mangalam, s tudent pro jec t manager, commented, “The door s

of fer a ver y s leek and modern appearance, which contras t s

ver y n ice l y w i th the ex ter io r rus t i c wood accent s .”

Addressing efficiencyOur H2Ouse unique ly addres sed water and energy ef f i c ienc y. Not

only d id the UC Dav is team cons ider the energy ef f i c ienc y of

the ac tua l produc t s , they a l so wanted to use produc t s that were

ef f i c ient l y manufac tured.

The team used a new wal l s y s tem ca l led BamCore , featur ing pane ls

made in a low embodied energy process us ing U.S . t imber bamboo.

These panels don’t require wood studs, which reduces thermal bridging.

Another cha l lenge was the reduc t ion of a i r l eakage, of ten the

main source of energy inef f i c ienc y, into and out of the house. The

team used AeroBarr ier™ and Aeroseal ® to p lug t iny seams, c rack s

and ho les that would a l low for condi t ioned a i r l eakage and /or

uncondi t ioned a i r inf i l t rat ion.

The team employed the Sunverge ® energy p lat form, featur ing a

combined so lar inver ter and bat ter y as we l l as a smar t and adaptab le

energy management s y s tem. Th is he lped opt imize energy produc t ion

and usage by determin ing gr id - and home - leve l ac t i v i t y and demand.

The team a lso augmented the w indows wi th a so lar- intu i t i ve,

thermochromic coat ing f rom RavenWindow ®. I t automat ica l l y t int s

to prevent excess heat ga in.

Intermediate bulk conta iner s co l lec t grey water (re lat i ve l y c lean was te

water) and ra inwater. I t ’s then reusab le, e l iminat ing the need for

ex ter io r potab le water usage.

The house a l so features dua l energy and water moni tor s of a l l

ind iv idua l e lec t r i ca l c i rcu i t s and hot and co ld water l ines . Occupant s

have access to th is usage data feedback so they can bet ter manage

usage and reduce i t where necessar y.

Shar ing some thought s on the i r exper ience

“We a l l l earned how to create a success fu l team, inc lud ing

how to fos ter camarader ie, communicat ion, coord inat ion and

engagement . Work ing wi th a d iver se group, i t ’s never easy

to appea l to ever yone, but we had a lot of success s imply

because peop le cared.”

Geof f rey Mangalam

“The So lar Decath lon i s a great exper ience that teaches

you many th ings you would never learn in a c las sroom.

I t prov ides you wi th knowledge and exper ience that w i l l

F lorence Chung

“The compet i t ion i s a rea l l y integrated learn ing process that

b lends academic learn ing wi th profes s iona l , rea l - l i fe,

hands- on exper iences .”

Ke i th Ruan

“I thought the bes t th ing about the So lar Decath lon i s

that I took par t in an incred ib ly cha l leng ing pro jec t that

d i f fe rent iates me f rom many other co l lege s tudent s .”

Sustainability mattersAt JELD -WEN, we are commit ted to bui ld ing windows, door s and component s in a manner

that promotes env i ronmenta l s tewardship. In 1960, ef f i c ient resource use such as rec yc l ing

and mater ia l reuse made sense because i t was good bus iness . We began the use of f inger-

jo int and engineered wood component s because i t produced a bet ter produc t .

We be l ieve that a hea l thy env i ronment and hea l thy bus iness prac t i ces go hand in hand.

We are dr i ven by a phi losophy to be good s tewards , and do th is by des igning long - las t ing,

energy - sav ing windows and door s . Our manufac tur ing process uses rec yc led was te mater ia l s .

We a lso manufac ture produc t s c lose to market s to min imize fue l consumpt ion and greenhouse

gas emis s ions .

We were ver y happy to work w i th UC Dav is on th is pro jec t and hope that i t prov ides an

atmosphere of learn ing around the many oppor tuni t ie s for ef f i c ient use of resources .
