![]() By looking at the total energy expenditure to Of work and energy already invested in the site. To address site selection early in the project development process to ensure that issues like solarĪccess are considered.35 An existing site with existing buildings represents a substantial amount Systems and the use/reuse of existing structures and infrastructures. Materials, commuting, security, accessibility, energy consumption, and the impact on local eco. Site selection and building orientation haveĪ large impact on building efficiency, as do external factors such as energy spent transporting Infiltration all have a huge impact on energy use. The building envelope has the greatest impact on energy efficiency sinceĮach function is specific to the characteristics of the building. The use of building controls for implementing peakĭemand reduction is an effective strategy.ĥ6 Renewable Energy Guide for Highway Maintenance Facilitiesīuilding Envelope. Of space types within the building or site. Nonetheless, there are still some opportunities for demand reduction, depending on the mix This is lessīeneficial for maintenance facilities since the maintenance areas are typically not air conditioned. In the summer, and high demand charges are established for summer peak periods. In much of the United States, utility peak demands are set ![]() Of equipment operation or other meansâthe use of on-site generationâare best able to benefitįrom reductions in demand charges. Facilities that are able to reduce their demand through strategic scheduling That increase air conditioning requirements and hence electric power generation requirements) Short periods simply to meet spikes in demand resulting from extremes in weather (e.g., hot spells Its requirement for investment in âpeaking plants,â which are generators that are used for relatively However, from the utilityâs perspective, reducing peak demand is very beneficial since it reduces In a way that simply moves the energy use to another time period (referred to as load shifting). Reducing peak demand may not save much energy if the reduction is temporary or if it is done Understanding the facilityâs electric use profile is the key to reducing peak demand. Typically, demand is measured over a short durationâĪ 15-minute time periodâwhich represents the instantaneous power draw of the facility. Many utility rates, especially those for commercial buildings, include energy usageĬharges plus charges based on demand. This strategy is mostīeneficial when the electric rate schedule includes high demand charges for power use during the Utility-defined peak demand periods as a means of reducing utility bills. ![]() Spaces will have higher heating, lighting, and ventilation loads compared to the industry averageįor commercial spaces, while buildings used for non-shop activities should follow much moreĭemand reduction refers to the strategy of reducing electric power requirements during Operation, accounting for 36% of total consumption, followed closely by lighting at 21%. Tion in most commercial buildings, and this holds true for maintenance facilities of all types.Īccording to the International Energy Agency, space heating is by far the most energy-intensive There are a few driving factors behind energy consump. Reduce the power generation requirements, which will either reduce the quantity of renewableĮnergy that needs to be generated or decrease the conventional energy that still needs to be Having efficient and functional facilities can greatly Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.Įnergy efficiency is a key piece of the puzzle when evaluating energy strategies and especiallyĬapital-intensive renewable energy projects.
