Therefore, in this work, we abstract the functionality of the HVAC system by using the existing distributed heating/cooling infrastructure in buildings to provide a low-cost centralized command and control mechanism namely Retrofitting low-cost Heating Ventilation and Air-Conditioning (RetroHVAC) system...
Efficiency on a budget: Easy, low-cost retrofitting 来自 国家科技图书文献中心 喜欢 0 阅读量: 18 作者: Alan Cotterill 摘要: Eleven years ago we bought a near-new four-bedroom brick-veneer house in Wagga Wagga, an inland town in NSW, in an area that experiences hot summers and cold ...
are more vulnerable to humidity. They are typically used for retrofitting and inside double- or triple-pane windows, known as soft-coat low-e windows. Sputtered e-coatings are capable of offering a much lower emittance rate than pyrolytic, as low as 0.02. ...
In light of this, the present manuscript proposes an ultra-low temperature refrigeration unit based on an indirect cascade system, developed by retrofitting a standard low-temperature R290 packaged unit. In this investigation, firstly, the suitability of the original components is assessed and, then,...
Yoghurt window coating proposed as emergency heatwave measure British engineer Tom Greenhill is proposing painting the outside of windows with yoghurt as a low-cost,low-energysolution to keep UKhomescool during heatwaves.More Vessev launches electric hydrofoil ferry that "flies above the waves" ...
Towards the goal of zero-carbon building retrofitting with variant application degrees of low-carbon technologies: Mitigation potential and cost-benefit an... To illustrate the impacts of the application of low-carbon technologies on zerocarbon building retrofitting, the mitigation values and abatement ...
Initial investment cost: select solutions within the budget to control the project's initial investment cost. Energy efficiency: opt for solutions with significant energy-saving effects to reduce operational costs and carbon emissions. b. Selection methods: weighted scoring method: assign weights to ...
One way of enhancing the structural performance of an existing masonry building is to reinforce the already damaged areas of the building or parts that are likely to be subjected to tensile stress or strain in the future. This needs to be carried out at minimal cost and with minimal disruption...
But the dollars and cents don’t stop there. You need to factor in the cost of using the bulb — and the great thing about LEDs is that using them doesn’t cost very much at all. For instance, a traditional 60-watt incandescent light bulb will add about $7 to your energy bill each...
It can be found that not only lifetime cost-benefit ratios but also the financial return period for each dollar invested seismic retrofitting can be identified conveniently. Additionally, they are useful information for making decisions about whether to retrofit a building or not....
