A dormer bungalow in Grouville, constructed using a high specification build system from local firm JecoHomes, has become the first in Jersey to be designed and built to a rigorous European green energy standard.
Le Jardin de Bas, which was built using construction materials and a ventilation system that ensures maximum energy savings, is the first in the Island to receive the EnerPhit certification from Passivhaus (or Passivehouse), a European energy performance standard.
The recently built 3300ft2 5-bedroom home, which involved a radical re-design and large extension of a small existing property, features a jointing system that helps to create an airtight building, while airflow is maintained by combining mechanical ventilation with a heat recovery system (MVHR). Using this MVHR system, heat from the outgoing warm stale air is applied to heat incoming fresh air, helping to further reduce heating demand and energy consumption.
As an illustration of the effectiveness of the construction techniques employed, the home has no need for radiators, other than those in the bathroom for towels and a wood burning stove in the lounge, which is a feature rather than an essential. The property is home to three adults and two teenage children and the homeowners, who are delighted with the savings made, have reported that their energy bills in the first 18 months of occupation are only just over £100 a month.
JecoHomes has worked with partners to build a portfolio of environmentally responsible properties in recent years, each tailored to meet the specific requirements of property owners. Projects have included luxury homes, a granite cottage and an oak frame pool house.
Greg Woods, of JecoHomes, commented: “Homeowners generally want a home where they can reduce energy costs wherever possible. It’s good for the environment and saves them money in the long term. We work alongside architects and construction partners to build homes that are kind to the environment and reduce heating costs. We are delighted that our latest project has achieved this prestigious performance standard.”
Passivhaus homes have been built in countries throughout Europe, the far East, Australia, New Zealand and North America since the modern performance standards were set in Germany and now Jersey has its first such property.
Greg added: “A home that is designed well and uses renewable technologies does not have to look different to any traditional home. It can be built with granite, or with rendered walls and the architectural style can be anything you choose. When constructing a property, the heating and ventilation systems are concealed within the structure and are virtually unseen.”
“I would encourage anyone who is interested in knowing more to contact us or visit our website to see what can be achieved.”
