Once spring cleanup is done, you may feel ready to tackle some renovation projects this summer. If so, you’re not alone: 62 percent of homeowners plan to undertake a home improvement project this year, according to a Harris poll. Homeowners will renovate to improve their home’s appearance, livability and energy efficiency, the survey found.
HVAC systems consume 25% to 30% of the energy in a typical commercial building; functionally intensive buildings with controlled environments and large process loads can consume more than this. Providing cooling comfort and energy efficiency in nonresidential buildings is an ongoing challenge for mechanical engineers. Emphasis on building performance and adoption of energy-efficient building codes is increasing.
