New York has set an ambitious goal of cutting co2 emissions in Manhattan by 50 per cent by 2050 and 80 per cent in the whole city. The House at Cornell Tech is an essential step towards this. In a densely packed metropolis where the built environment creates 70–75 per cent of greenhouse gas emissions, nearly all generated by heating and cooling systems, better buildings are the solution.
This approach to building, which was pioneered in Germany, maximizes the use of passive measures (or solutions) to reduce the energy need using insulation in the design of the building. Strict limits on energy use for heating, cooling, and thermal comfort are applied as a criterion to focus on efficiency first.
High-quality insulation is central to passive construction, creating an optimal indoor climate by minimizing the need for active heating and cooling. In the House, architects exclusively used ROCKWOOL stone wool products. A 280mm thickness of CAVITYROCK® semi-rigid insulation boards as well as AFB® and ROCKBOARD® are used to wrap the building in an insulated blanket.
It’s estimated that The House will save 882 tonnes of CO2 emissions per year – the equivalent of planting 5,300 new trees – helping New York City in its quest to lighten its environmental footprint.
