Abstract

Driving energy saving building is always the important material base of social development in the process of modern society's high speed development, thus energy saving problem should obtain the great attention of all trades and professions, should become the problem of whole society pays close attention to jointly, makes joint efforts；The raising of national life level, so that specific gravity of the building energy consumption in entire energy consumption is increasing；Building energy conservation refers to the planning in building, design, creates and (reconstruct, enlarging), in transformation and use process, execute energy conservation standard, using energy-saving technology, skill, equipment, material and product, improve thermal and insulating performance and heating, air conditioner refrigerating heating system efficiency, reinforce the operational management of building energy consumption system, using renewable energy, under the premise of guaranteeing indoor environmental quality, the energy consumption of heat supply, air conditioner refrigerating heating, illumination, hot water supply is reduced.

Description

Driving energy saving building

Technical field

The present invention includes construction energy consumption and Energy in use two large divisions to building energy consumption；Energy consumption in building course, including Construction material, building components and fittings, the production and transportation of Architectural Equipment and the energy consumption in construction and installation；In use process Energy consumption, including heating, ventilation, air-conditioning, illumination, household electrical appliance, elevator and hot and cold water in building construction and structures validity period The energy consumption of supply etc.；We are generally defined as the range of building energy conservation to reduce the energy consumption in building use process, ordinary meaning On the building energy consumption said refer mainly to building Energy in use.

Background technique

Currently, energy for building waste in China's is extremely serious, and the speed that building energy consumption increases is considerably beyond China's energy The speed of production increase, if this highly energy-consuming building sustainable development is allowed down, national production of energy certainly will be difficult to for a long time Such waste type demand is supported, to have to be forced the large-scale energy-saving reconstruction of old buildings of tissue, this will expend more people Power material resources；Energy use efficiency is actively improved under construction, it will be able to which alleviation national energy short supply state significantly promotes state, China The long-term sustainable of people's economic construction develops.

Summary of the invention

Solution of the invention be roof heat preservation, it is heat-insulated be the energy-efficient emphasis of building enclosure, the section of roofing heat-insulating layer Can measure main points, one is roofing heat-insulating layer should not be selected, density is larger, the higher thermal insulation material of thermal coefficient, in order to avoid roofing weight Amount, thickness are excessive；The second is roofing heat-insulating layer should not select the biggish thermal insulation material of water absorption rate, to prevent roofing wet construction Shi Yinbao Warm layer largely absorbs water and reduces heat insulation effect, such as selects the higher thermal insulation material of water absorption rate, gas vent should be arranged to arrange on roofing Except the moisture for being not easy to be discharged in insulating layer；The method of roof insulation cooling has: aerial ventilation, roof water storage or timing water spray, room Top greening etc.；South China sunshine-duration summer is long, and intensity of solar radiation is big, to prevent a large amount of radiant heat intrusions indoor, Effectively insulating layer should be set on roof, this is an important construction measure for reducing air-conditioning energy consumption.

Specific embodiment

Present invention implementation is as follows, should reduce building appearance area in principle, suitable control shape coefficient of architecture is built The ratio between the volume that exterior surface product is surrounded with it, reduction building sides is wide, to improve existing micro climate；In the planar cloth of building Office's aspect, the selection of direction are critically important；It is indoor that winter should have suitable sunlight to inject, and cold wind is avoided to blow；Summer then subtracts as far as possible In few direct sunlight room and wall face, and there is good ventilation；As it can be seen that considering that building is with north-south from energy conservation and thermal environment Or preferably close to north-south, East and West direction is avoided, if cannot all be north-south, main room is preferably located at the winter leeward portion with southern exposure Position, reduces the heat dissipation capacity of building enclosure；Building appearance area should be reduced in principle, suitable control shape coefficient of architecture is built The ratio between the volume that exterior surface product is surrounded with it is built, reduction building sides is wide, increases depth or increases assembly.

Claims (1)

1. the present invention is that the heating of high energy efficiency, air-conditioning system and the measure of the indoor cooling and heating load of reduction are parallel, could veritably subtract Few heating, air conditioning energy consumption；Firstly, according to building the characteristics of and function, design the hvac equipment system of high energy efficiency, such as: Heat pump system, energy-storage system and district heating, cold supply system etc.；Then, it is supervised in use using energy management and monitoring system Superintend and direct and regulate and control indoor comfort level, indoor air quality and energy consumption；This is largely effective for adjusting sunshine, saving the energy , especially glass-wall building, it is necessary to consider good sunshade, dark conditions.
