Volume 10 / Issue 1 Dear Readers, the smart grid is on the critical path of america's energy future. It intersects energy supply, demand, and infrastructure. the federal government has authorized billions of dollars to implement the "smart grid" and "smart metering" in several states with leading electric utilities. Buildings consume about 40% of the energy used in the u.s., and most of that energy is used for heating and cooling, with peak demand often coincident with utility peak loads. We can expect the smart grid to be an increasingly important consideration for facilities as utilities roll out smart meters and for energy services that use them. In this issue of EnVisioneering Solutions, michael oldak, Vice president and general counsel, utilities telecom council, maintains that peak demand reductions would allow utilities to forestall or forego new power plant construction, and reduce or eliminate “peak plants” that are the least efficient and operating during peak hours, as “spinning reserve” in case needed. our cover story, beginning on page 2, outlines the perspectives raised by industry experts at the 14th enVisioneering symposium, the smart grid and Beyond, which took place in scottsdale, ariz., in november. among the most significant findings were that the concept of energy management will eventually extend from energy efficiency to also include load shedding and load shifting in response to grid or other supply, demand or environmental conditions. economic returns will be driven by utilities implementing real-time-, time-of-use and/or dynamic pricing to help harmonize peak, off-peak and critical peak supply and demand resources. meanwhile, building owners can hedge their energy bets by making their facilities more environmentally sustainable and energy efficient, smarter, and more flexible using best-available products. here we bring you three distinct case studies in this issue of Solutions - a swimming pool operator, a university, and a foodservice refrigeration plant - who have worked with danfoss and taken steps to reduce energy costs. Danfoss helps the Geneva Lakes Family YmCa in Lake Geneva, Wis., save almost $10,000 in energy bills. Story on page 17.
