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.”

Changzhou Tian'an Villa is located in Wujin District of Changzhou City.

Changzhou Tian'an Villa is located in Wujin District of Changzhou City.

Changzhou Tian'an Villa is located in Wujin District of Changzhou City. With a total construction area of about 500, this Project adopts a full set of Uponor radiant air conditioning system, which includes ground radiant system, ceiling radiant system, hydraulic conveying system, air conditioning automatic control system and fresh air dehumidification system. Uponor Engineering Department is responsible for the whole project’s conceptual design, product procurement, construction guidance, quality supervision, and system debugging.Owners, based on a preliminary understanding of the radiant system, can put forward their requirements on thermal comfort, indoor air quality, noise, airflow distribution, temperature and humidity control, future maintenance and other aspects.

1. Unlike traditional convection air conditioning (fan coil unit, air-air conditioning, etc.), radiant heat exchange makes up about 60% of the radiant system and the amount of body heat dissipated by radiant is largely increased, which is quite similar to what ASHRAE describes as human body heat exchange comfort model: 30% convection heat exchange, 45% radiant heat exchange and 25% evaporation heat exchange. Moreover, the radiant system could also reduce or increase the temperature of surrounding walls accordingly to cooling or heating conditions, so as to further improve the comfort and friendliness of indoor environment.

2. Compared with terminal equipment of traditional air conditioning that involves a lot of condensed wet surfaces, which may cause the condensate water pan to breed a large number of bacterium and seriously endanger human health, Terminal equipment of radiant conditioning is free of wet surface, and indoor humidity is also strictly controlled, which is conductive to improving the cleanliness of indoor air.

3. Terminal of radiant air conditioning is free of any moving parts, thus eliminating the indoor noise source fundamentally, and further creating an extremely pleasant and wholesome environment for the customers to live in.

4. For most people that have long been subject to air conditioning environment, it is likely for them to suffer the so-called "Air Conditioner Syndrome",which is mainly caused by insufficient fresh air indoor, growth of mould in air conditioning system, long-term blowing feeling and so on. As mentioned above, radiant system can fundamentally eliminate the three hidden dangers, and thus deserves the name as a new generation "immune air conditioning".

By adopting the high temperature cooling source, this system can also effectively reduce the operational energy consumption of air-conditioning system while improve its indoor thermal environment.Ground radiant system adopts Uponor's five-layer oxygen barrier 20mm Pex-a pipeline, so as to ensure the quality of circulating water of air conditioning, improve the heat exchange performance of cold and heat source equipment, and prolong the service life of system.Ceiling system adopts Teporis precast gypsum radiant panel, with cooling capacity of unit area in design condition reaching 85W/m2, therefore largely eliminating users' worries about the cooling capacity of the radiant system. Gypsum radiant panel comes with an insulation layer to ensure that cooling capacity is supplied to air conditioning area to the full extent, and avoid the waste of heating and cooling capacity. Radiant panel adopts modular construction, which is easy and convenient to install, and conductive to guaranteeing the aesthetic effect of interior decoration while ensuring the effect of air conditioning.Hydraulic conveying system is composed of water mixing center, balance valve and main transmission pipeline. Uponor water mixing center well integrates the control module, electric three-way valve and circulating water pump, which ensures the allocation of hydraulic system on demand and on time, and realizes the efficient operation of hydraulic system intelligently.Air conditioning automatic control system adopts a full set of Wave Plus+ Move Plus wireless control system, which helps to eliminate the wiring process of conventional control system, and largely reduce the costs of construction and maintenance. Moreover, it also manages to link the whole indoor and outdoor equipment together organically and thus ensures the efficient and coordinated control of the whole system. Dedicated dehumidifying fresh air ventilator adopts a dual-cooling mode characterized by refrigerant + air conditioning cooling water, which not only ensures the  dehumidification effect of system but also gives consideration to the energy consumption of fresh air dehumidification. Fresh air dehumidifier could also improve the air quality indoor, and control such key parameters as TVOC, PM2.5 and CO2 concentration that are widely concerned by the public.

The whole set of radiant air conditioning system has managed to provide the owners an ideal indoor microclimate environment characterized by high comfort, high energy efficiency, high air quality, and high intelligence. And Uponor, in turn, is highly recognized and acknowledged by the owners based on their actual experiences.

• Eight floating holiday homes on three footbridges 
• Underwater connection to houseboats 
• Integrated heating cable keeps cables frost-free

Life on the water decelerates: Slowly it flows along, quietly hitting the aluminium hull, the sun's rays reflecting on the smooth surface, birds can be heard, fish show themselves and the surrounding nature is so close. What was developed as a hip alternative in the hip big cities with rivers, canals and lakes is now also firmly moored in the Elbe-Weser Canal on three jetties of the new houseboat marina in Bad Bederkesa. The eight floating holiday houseboats are connected to the local drinking water supply and sewage system with 450 m pre-insulated Uponor Ecoflex Supra PLUS pipes. Thanks to the integrated heating cable, the pipes remained frost-free even in the first winter.
Villa Neureuther

Villa Neureuther

In Villa Neureuther in Garmisch-Partenkirchen, everything is geared towards comfort, and the quality is right down to the last detail. This also applies to the underfloor heating and cooling as well as the drinking water installation. Here ski stars Miriam and Felix Neureuther rely on systems from Uponor.

In the disciplines of slalom and giant slalom, Felix Neureuther is probably nobody's equal: the son of sports legends Rosi Mittermaier and Christian Neureuther was already skiing at the age of two. With 13 World Cup victories, 47 podium places and five World Cup medals, he has become a skiing legend himself. His wife Miriam also looks back on a very successful sports career in cross-country skiing and biathlon. The young family set the same high standards for their new home in Garmisch-Partenkirchen as they did for their sport. The location right next to their parents' house is a statement: the Neureuthers are grounded family people.
