Originally established in Whanganui, eHaus had issued licences to builders throughout New Zealand and was looking to establish a presence in Marlborough, which was perfect timing for Micky and Tash. “We were looking to move and establish our own company at the time, and approached eHaus,” says Micky. “What drew me to eHaus was that ultimately we were not just building to the Building Code, which is the minimum required performance of a house. We bought the licence for Marlborough and moved down in 2020, establishing Dean Building & Renovations (DB&R) as the breadwinner for the business. With our eHaus licence agreement, anything that is designed by eHaus for the Marlborough region, will be built by our company. I’m the Marlborough face of eHaus and go through the consultation with the client, support them through the pre-design process taking part in meetings with eHaus designers/architects to ensure there’s a common language.” While eHaus has a group of designers and architects around the country, many of whom are passive house certified, that doesn’t exclude clients who may already have their own designers, but want a high performing home. “We will work with the client’s designer to get the design to the standard for the energy performance they are looking to achieve. Energy efficiency is woven into the fabric of every eHaus using the passive house planning package (PHPP) design tool. This tool allows us to determine the most suitable form of the building, and instantly shows the impact of design decisions on the building’s energy efficiency.” Micky explains that five separate areas are targeted when building an eHaus. “The first is air tightness, mechanically ventilating as much air as we can. The second is the mechanical ventilation, and that is controlling the air movement so that it’s balanced. The third is insulation. We spend a lot of time calculating the insulation requirements, which are also dependent upon the location of the build. The fourth is thermal bridge free – keeping heat in just like a thermos flask. “The fifth is passive certified joinery including external doors and windows that need to be airtight. This means no condensation, mould or unwanted draughts. The joinery is often imported from Germany. Beautifully engineered with double or triple glazing to capture free solar energy and reduce heat loss.” DB&R/eHaus Marlborough is now completing its first eHaus designed home. Located within Blenheim’s prestigious Rose Manor subdivision, the house is a 215sqm, single-storey home, which Micky describes as reasonably understated, while showcasing energy efficiency and built to achieve Passive House certification. “The house is nearing completion and has passed the air-tightness test. All the insulation has been calculated and all standards have been achieved or exceeded. “That all comes down to a much healthier, more energy-efficient, comfortable home to live in.” Micky and the eHaus team are now in the design stage for the second home that will be built by eHaus Marlborough. www.evoelectrical.co.nz Servicing the wider Marlborough region, from Kaikoura to the Marlborough sounds.
