Eco-friendly Zembis House

With energy efficiency and thermal comfort at its core, the Zembis house draws on natural surroundings, making use of as much natural light as possible.

Project Overview

Zembis House is a project of the homeowner, builder Peter Zembis. Set on the coastline of Brighton-Le-Sands on the southern outskirts of Sydney, the design was to reflect the lifestyle of a young family in creating a place of nurturing, entertainment and escape. 

With energy efficiency and thermal comfort at its core, the house draws on natural surroundings, making use of as much natural light as possible. 

The brief to architect Gareth Cole, Ecologie Group was to design an energy efficient, solar designed home encompassing architectural elements with practicality. The existing dwelling was a rundown single storey asbestos ridden shack, which was knocked down to build a four bedroomed sustainable home made from CSR Hebel with 7 star energy rating.

It accommodates a combined living dining kitchen area, two toy rooms, one study, four upstairs bedrooms, bathroom plus a powder room and ensuite off the main bedroom. 

"Hebel reduced the requirements for expensive steel framework and the installation of the first floor walls only took three days to complete."
Peter Zembis, E-con Group.

Challenges/ Requirements

The acoustic and thermal properties of Hebel were a key consideration of the design. Incorporating Hebel PowerPanel on the exterior of the dwelling and PowerFloor for the upstairs floors, owner builder Peter Zembis was able to achieve an incredibly comfortable and efficient living environment.

The Hebel PowerPanel system is a high performance masonry panel system which provides solid, secure, steel-reinforced walls boasting strong acoustic values for added privacy and sound insulation. With up to three times the insulation R-value of a traditional 110mm house brick, the unique combination of thermal resistance and thermal mass can assist in reducing energy costs.

Hebel PowerFloor is made of 75mm thick aerated concrete panels reinforced with corrosion protected steel. Extremely strong, yet lightweight and easy to install over steel or timber joists, PowerFloor gives the feel of a concrete floor at a significantly lower cost. With superior acoustic and thermal insulation properties to provide a more comfortable and tranquil home, the thermal efficiencies of PowerFloor reduce the reliance on heating and cooling appliances, enabling a comfortable home all year round.
