Lomax Builders Ltd breathes new life into Victorian School Thanks to Minus7’s award-winning hybrid technology, Lomax Builders Ltd blends stylish, subtle design with efficient eco-friendly innovation in their refurbishment of a beautiful Victorian School House. “With so many choices on the market, it’s hard to know what you’re getting” said David Lomax “but Minus7 have been really good. When people ask me, would you use them again? I say Yes!” Zero net carbon; zero net running costs by design. Archetech - Page 52 Using the best of solar thermal, photovoltaic, heat pump and energy storage technologies in one simple aesthetically pleasing building-integrated solution, Minus7 enables the ownerlandlord of the School House to charge a reduced price for heat to tenants, creating an additional revenue stream alongside the rental income. “The theory behind Minus7 is mindblowing; it just makes so much sense” The system is comprised of three parts – a roof, a Solar Energy Processor and thermal stores, fulfilling the heating and hot water needs of happy tenants who control the system via traditional thermostats and timers. Working with conventional roof construction methods, Minus7 bespoke roof tile planks blend in seamlessly without need for unsightly bolt on panels. Weighing 27kilos per square metre – the equivalent of Welsh slate - two areas of St Mark’s Boys School House roof have been replaced with Minus7 tileplanks in slate grey. Quietly and discretely, they absorb energy day and night, down to temperatures of minus 7 degrees Celsius. This energy is then stored in three thermal stores, completely hidden under an area of decking in the courtyard, allowing the distinctive Victorian character of this beautiful building to be retained. The solar energy processor further ensures Minus7 meets its bespoke contractual annual heat provision performance guarantee, provided with every Minus7 project. Appealingly simple Lomax Builders Ltd has been so impressed with Minus7’s performance and customer care that they are now starting their third large development utilising Minus7 technology. Minus7’s in-house design and installation team provides creative suggestions appropriate for each project’s aesthetic and innovative needs. Remote monitoring services provides complete transparency of the energy generated, used and stored, allowing the Minus7 after-care service team to proactively ensure the system is working as efficiently as possible, without disrupting its occupants.
