Still digging out from an end of the year crush of emails, we came across new on a recent study done by green building consultant Jerry Yudelson. Despite advances in green building in the U.S., Europe is still leading the pack, according to the study. In it, Yudelson documents a range of green building practices that engineers and builders are employing overseas but have yet to catch on in the U.S.
2. Use of earth tubes for preheating/precooling outdoor air.
3. Decoupling of ventilation and cooling, predominantly using displacement ventilation with
radiant cooling (chilled ceilings, radiant-slab systems for low-temperature heating and higher temperature
4. Increased incidence of using extensive thermal mass in thermally active building systems,
5. Mixed-mode (fan-assisted) natural ventilation through central stack atrium also used for
6. Chilled beams (to a limited extent in the right applications).
7. On-site use of renewable energy from wind and solar, to geothermal, and moving toward
cogeneration/tri-generation systems with biomass fuel.
8. District cooling and heating to allow for more effective application of renewable energy towards a low-carbon approach.
9. A well developed market that can support equipment manufacturers providing space-effective,
modular packaged systems that provide high efficiency and reliability (for such applications
as gray-water reuse, rainwater reuse, heat recovery ventilation, solar domestic water packages,
integrated boiler heating systems).
10. Exterior active solar control systems, such as moveable shades and shutters.
