In, this paper we suppose that CEP contains all the energy
management issues within the entire construction period of. The
project. The CEP methods are different at different stages of
community construction.
At the CMP and CRP stages LEED-ND,,, BREEAM Communities
and other standards or rating system for low-carbon community
are widely used. For most countries and. Cities there is, no national
.Or local standard for CEP. Energy control indicators are rarely
contained in outcomes of CRP. LEED-ND is used for community
planning. Universally which promotes, low-carbon community
development. With the aid of these ecological community rating
systems. And, design handbooks urban planners and energy engineers
pursue low-carbon community energy system. Energy savings
.Targets and renewable energy percentage in these rating
systems are widely quoted as obligatory targets for low-carbon
community. Planning project. Based on these indicators related to
energy planners draw, up a community energy utilization plan to
regulate. Community energy system design and equipment installation.
This method is a top-down, operation model which is
.Similar to the current urban planning mode and familiar to urban
planners. In this pattern the low, carbonization of the. Community
energy system is driven by upper policy. CEP can be blended with
current urban planning, systems easily which. Is why CEP is widely
implemented in most community development project.
Sometimes however, this reference, process is difficult. Because
.The rating system is not always suitable for the project. CEP
currently needs an additional new team. Members of this team
include. Urban planners and energy experts.
At the CSP and, AD stages community energy system analysis /
simulation models (RETScreen,, H2ERS EnergyPlan,,,, DER-CAM
EAM etc.) are extensively used. Engineers and proprietors can
.Use these tools to design distribution or renewable energy systems.
They can also select energy efficient technologies. And plants
with constraint of total investment by these tools. They can use
local renewable energy (such as, solar energy. Wind energy and
biomass energy) and fossil fuels (such as, natural gas petrol and
coal) to satisfy neighborhood houses'. Heating cooling and, electricity
.Demands with high energy efficiency and low investment.
With the aid of these, computer tools community energy facilities
planning. And designing can be more efficient and easier.
In, recent years most research achievements have pertained to
community. Energy demand, prediction methods methods of
available energy resource evaluation and energy system structure
optimization. Algorithms.Including all critical contents of CEP.
Computers tools for building energy simulation can output the
load of a single. Building. The sum of the loads of each single
building becomes the total energy demand of the community.
Statistical regression. And load index are always used to predict
long-term community energy demand.
