Putnam County Home, Putnam County, New York, USA

Optimum energy efficiency

The private residence of Malcolm Rowe in Putnam County boasts an immaculate energy envelope and has gained recognition as an Energy Star® Version 2.0, Home Energy Rating System (HERS) Index 47 labelled home. It is certified as a U.S. Environmental Protection Agency (EPA) Indoor AirPLUS labelled residence and is set to achieve received LEED® for Homes Silver certification. 

Rowe’s construction objective was to achieve ultimate thermal comfort and superior air quality. To achieve reach this goal, he hired Walden, N.Y.-based Aaron Ourada with Radiant Technology LLC. Ourada prioritized comfort at the top, followed closely by sustainability and energy efficiency. He achieved these goals by installing Uponor radiant heating and cooling systems, filtered whole-house ventilation and automated humidity controls.

Achieving ENERGY STAR® recognition at home

Integral to sustainable design, the home’s efficient thermal envelope includes R26 insulated concrete forms (ICFs) below grade on an R10 slab. R26 ICFs continue above grade to the framed R54 roof sprayed with three inches of closed-cell and six inches of open-cell insulation. The home’s efficiency is furthered through a water-to-water ground source heat pump (GSHP) for an Uponor radiant floor heating and cooling system. The heat pumps are fitted with a heater which reclaims energy for domestic hot water storage and dehumidification reheat. 

The home’s in-floor radiant heating and cooling is embedded in concrete for each floor; the basement is slab on grade, and the second and third floors are poured concrete over ICF decking. The concrete thermal mass construction acts as a thermal energy flywheel to offset overnight peak loads so the mass stores energy and regulates temperate fluctuations. 

For radiant cooling, the GSHP system reverses from heating mode to cooling, charging the buffer tank with chilled water instead of hot water. A variable-speed mixing pump controls the water temperature from the buffer tank to the radiant floor cooling system. 

To say the homeowner is pleased is an understatement. “The builder guided me through our joint vision for a highly energy-efficient house comprising a geothermal energy source, radiant heating and cooling, insulating spray foam and web-enabled monitoring and control systems,” he says. “All the planning paid off.”

The biological treatment plant is worth its price

The Murto family, from Savonlinna, Finland, live in a sturdy log cabin built in 1845. The waste water system of the house had last been overhauled in the 1970s and the old concrete wells and absorption field had reached the end of their lifecycle. The choice was between renovating the old wells and getting an Uponor biological treatment plant, and the decision was not difficult to make.

Renovation of the district heating piping system of six housing companies

Six housing companies located in the Hurttivuori district in Turku have a joint heating plant – Nokikana Oy. The terraced houses, which were built between 1975 and 1977, contain a total of 104 flats. Heating and water are supplied to all flats by a joint heating plant. Renovating the piping system became a necessity due to leaks. The plant's insulated elements were renovated in such a way that all residents were able to live in their homes for the entire duration of the renovation.

D'or Appartements

In one of the most beautiful parts of Budapest, at the bottom of the Sas hill, there is this 88 flat condominium called "D'or Appartements", which consists of 3 blocks. On the 1.23 acre property, there are three 5-story blocks of 32, 31 and 25 flats respectively. The most important aspect in the design of the flats was to create ideal living-space, thus homes between 46 m2 and 105 m2 can be found in the buildings.
