Cayman has been granted its first gold certification under the Leadership in Energy and Environmental Design (LEED) program.
A recently-built house at The Venetia development in South Sound was awarded the prestigious environmentally friendly status by the United States Green Building Council.
It is also the first residential project to receive the rating in the Caribbean, although there are a number of LEED Gold projects in the region certified under the commercial/institutional rating systems.
LEED for Homes is a green home-certification program which rewards buildings that are designed and constructed to be energy and resource efficient and more healthy and durable for the occupants.
The LEED Gold house is the personal home of Philip Nadeau – senior interior designer at DDL Studio Ltd. – who also designed and managed the project.
Obtaining LEED certification encompassed a technically rigorous process that included a home energy rating and regular onsite inspections throughout construction.
Philip worked closely with GreenTech Cayman which supplied technical assistance for the LEED certification. Their Green/HERS rater provided third-party verification and testing, and made the process efficient.
“Due to the highly efficient energy systems in the home, our first electricity bill was net-zero and, over the summer, was just $150 per month,” says Philip. “During the cooler months, our home produces as much energy from the solar panels as it uses from the electricity company.”
The four-bedroom contemporary Nadeau residence features insulated concrete forms construction, spray foam insulation, 6kW photovoltaic system, low-flow plumbing fixtures, hurricane-rated windows, drought-tolerant landscaping and efficient irrigation. Additionally, it has efficient air-conditioning systems, Lutron lighting controls, gas appliances, instant hot water heating, low volatile organic compound finishes and light-colored exterior surfaces.
Bella Verde, a speculative home under construction in Salt Creek, which Dart Realty is developing in partnership with GreenTech, is also aiming for LEED Gold certification in the near future.
