AT PERENNIAL BUILDING, WE KNOW THE DECISIONS WE MAKE ABOUT THE BUILT ENVIRONMENT HAVE A LASTING IMPACT ON HEALTH, EQUITY, COMMUNITY & THE ENVIRONMENT. THAT’S WHY WE FOCUS ON HOW TO BUILD HIGH QUALITY, HEALTHY HOMES THAT ARE BETTER FOR THE ENVIRONMENT & HOW TO BUILD MORE AFFORDABLY SO IT’S WITHIN THE REACH OF MANY AND NOT JUST A FEW.
perennial : lasting for an indefinitely long time; enduring.
OUR MAIN FOCUS IS BUILDING WITH HEMP & LIME, OFTEN REFERRED TO AS HEMP-LIME OR HEMPCRETE.
Hemp-Lime construction is a natural, sustainable building material made from hemp hurd (chopped up stalk of the industrial hemp plant) and a lime based binder. It is used in place of traditional insulation and acts as the substrate for natural finishes. It can be cast-in-place, spray applied, installed as bricks or as panels. Hemp-Lime has many advantages over conventional construction…
for the PEOPLE
It’s natural and non-toxic
It provides great soundproofing due to its acoustical properties
Hemp-Lime is hygroscopic meaning it absorbs and releases moisture in the air at a rate that maintains the ideal interior average humidity levels between 40% to 60%
It regulates air quality
It maintains a steady interior temperature due to the thermal mass properties of the material which reduces heating and cooling costs
Hemp-Lime can be finished with many different materials such as lime render & plaster, wood, stone and brick to accommodate the homeowner’s preferred aesthetic
for the PLACE
Fireproof and earthquake resistant
Pest and rodent resistant
Mold and rot resistant
Hemp-Lime gets stronger with time due to the curing of the lime binder
It can be used for floors, walls and ceilings to provide a complete envelope for the home
for the PLANET
Hemp is a highly renewable resource
Hemp-Lime is a “carbon-negative” material: more carbon is taken out of the atmosphere by the growth of the hemp plant and the curing of the hemp-lime than is emitted as a result of its production and application on site.
