Sika Corporation has donated building materials to the U.S. Department of Energy Solar Decathlon 2011 in support of EMPOWERHOUSE and ENJOY House. The U.S. Department of Energy Solar Decathlon challenges 20 collegiate teams from around the world to design, build and operate solar-powered houses that are cost-effective, energy-efficient and attractive. This year’s college teams displayed their homes on the National Mall in Washington, D.C. from September 23 to October 2.
ENJOY House by Team New Jersey members Rutgers, the State University of New Jersey, and New Jersey Institute of Technology incorporates a new way of approaching high-performance, energy-efficient residential design. The house utilizes precast, concrete insulated panels and passive solar strategies to reduce heating and cooling loads. Sika Corp. donated G410 roofing membrane and adhesive, along with accessories and metal to waterproof the precast concrete deck. The Precast Concrete was produced utilizing Sika’s Viscocrete technology, Air Entrainment and a new product – Sika Watertight Concrete Powder. This combination resulted in a High Performance and Waterproof concrete structure. All of the precast panel joints, windows and doors were sealed utilizing various Sika sealants. The team effort included precast concrete produced by Northeast Precast, the applicator/installer Dumar Services, LLC with Martin Dubois leading the team, and the General Contractor Skanska Construction.
EMPOWERHOUSE is a community-based approach to building affordable, net-zero housing that addresses all aspects of domestic life. This superefficient, solar-powered house was designed and built by architecture and engineering students from Parsons The New School for Design, the Stevens Institute of Technology and the Milano School of International Affairs, Management and Urban Policy. In addition to technical support, Sika AG subsidiaries donated G410 roofing membrane and adhesive, sealants for windows and concrete, admixtures that included a high range water reducer and air entrainment, and a new product – Sika Watertight Concrete Powder. The Sika Sarnafil applicator/installer was Delta Contracting Services led by Chris Dubois.
ENJOY House’s design was aimed at creating an affordable, functional, energy-efficient precast concrete house suited to the climate of New Jersey and intended for a couple that retires to the New Jersey shore. In addition to being ADA accessible, the house incorporates evacuated solar thermal tubes that heat domestic hot water and provide pre-heating for the hydronic radiant floor; high-performing, energy-efficient windows; a photovoltaic system with a daily output of 36 kWh, and energy recovery ventilators and dehumidifiers that keep cool air inside the house while providing fresh air from outside.
The EMPOWERHOUSE team is working with community partners, including Habitat for Humanity Washington D.C. and the D.C. Department of Housing and Community Development, to bring EMPOWERHOUSE beyond the National Mall. The team is constructing a second house in the D.C. neighborhood of Deanwood. After the Solar Decathlon, the two houses will be joined together to create a two-family home, and will be a model for affordable, net-zero housing that can be replicated around the globe.
Entrants must create a house that is affordable, attractive, and easy to live in; maintains comfortable and healthy indoor environmental conditions; supplies energy to household appliances for cooking, cleaning, and entertainment; provides adequate hot water; and produces as much or more energy than it consumes
This is the second participation in such an event for Sika Corporation. In 2009, Sika Sarnafil sponsored a team from the University of Florida, one of only two U.S. participants in the biannual global competition.
