i’m very much interested in the swimming pool application, coz pool filtration is a regular activity & is the second biggest consumer of electricity next to aircons! together w/ chemical free disinfection, one can have a truly green pool that is good for the people using it as well as the environment. chemical free pools (using saltwater chlorinators, ultraviolet filtration, ozone generators, etc.) don’t harm the swimmer’s clothes, their eyes, skin & hair like what chlorine does (u won’t have teary eyes w/ chemical free pools!) cancer survivors would definitely go for chemical free pools….u also save money on chemicals…in d near future, only stubborn ones will still be using chemicals in their swimming ‘fools’…

if ur running on diesel generating sets to filter ur pool…then ur a polluter. u can prevent d diesel emission by going solar! of course one can retrofit their pool pumps w/ solar panels, but you’ll be needing a lot of solar panels to run an a/c pump (w/ all the losses from the inverter). btw, inverters are expensive & seldom last a long time (except….but i’ve seen expensive branded inverters that are already dead but not old enough…could be the users?) if you have a cheap inverter from (hmmm)….buy another one, you’ll definitely need to change it in the near future….retrofitted solar powered pumps are not robust. the solution to the problem is the direct current brushless motor (dcbm) technology, they’re 90% efficient (so less solar panels needed!). german quality stuff are proven long lasting products (lorentz solar pumps are working w/out problems for more than 12 years in africa & other harsh environments – hope my memory serves me well). there are many solar pump systems installed in the phils. that are no longer in service today….many are even donated by developed countries…

lorentz solar pumps can be accessed via android devices (almost everybody got one or two of these). the system can be monitored via bluetooth. a pump manager software can control (remote configuration/programming) & monitor the system via a cloud based management. this can create a worry-free system.

maintenance of dcbm pumps are not complicated especially the helical rotor technology…non-engineers can be easily trained on the ground…

this is the future! (of course other applications like farming & water supply are cool but for starters… swimming ‘fools’ r better!) if ur wasting money on pumping as well as polluting the environment, u better stop d pollution…

d climate reality proj’s 24 hours of reality: d dirty weather report…..

glass window refs

a lot of stores, restaurants, canteens, groceries, etc. have a glass window refrigerator that were mostly provided for free by refreshment suppliers.

 

most, if not all of tis refs have oversized compressors dat sucks a lot of energy! they r made 2make sure dat d products on display r very cold. some even have blowers dat continuously circulate d cold air inside. tis refs don’t care bout efficiency….a ref w/ regular door (no glass window) s more efficient since it keeps the inside cool & well insulated. moisture build-up outside d glass window s a good indicator! one can feel d coldness of d glass window wen touched (compared 2 a regular door insulated ref).

if you’re selling d products at a higher price, e.g. in restaurants, hotels, etc. d amount of electric consumption can b compensated by d high profit margin. but if you only have a sari2 store or a bakery & sells d products at d suggested retail price….man…think again…u might b just paying off ur electric bills w/ ur profits!

inefficient appliances like tis have a high carbon footprint…thus r not good 4d environment. of course cold drinks r cool…but der r oder ways 2cool a drink aside fr using free but inefficient refs! n d long run…they’re not free at all…..

f u can’t help but use tis free glass windowed refs….at least save some money by not using dem 24/7. unplug dem at night & transfer perishable goods in a regular ref dat u use 24/7. could be inconvenient but worth d savings! if d lights inside r busted, don’t replace dem! or u can bust tis lights out. dey generate heat dat d compressors need 2 cool down. suppliers add d lights so deir products can b seen even in daylight!

one restaurant unplugged deir glass window ref indefinitely & was amazed to see how much deir electric bill went down! dey just use tis as a display 4deir available products 4sale. wen someone buys a product, dey get a cold one fr a regular ref.

glass window ref s a cool way 2display products. in case u don’t need 2 display d products…don’t use dem…dey’re ain’t efficient in cooling things down….f u really nid 2 use it…don’t use it 24/7!

Arousing interest in renewable energy and energy efficiency

Arousing interest in renewable energy and energy efficiency
by Dr. Arturo Mariano I. Figueroa

 
“If a company would ask you this question, why should I hire you? Is it because you are an engineering board exam topnotcher? What if not? Is it because you are good in math? What if not? Is it because you are a good basketball player? What if not? But if you say, you are member of a team that was able to save 250,000 pesos per month in energy cost of your university, then the company would ask you this…When do you want to start?”

These were some of the striking words of Engr. Eric E.A. Raymundo when he addressed the participants attending the seminar on Renewable Energy and Energy Efficiency under the principles of Zero Carbon Resorts project held on February 4, 2012 at the Dean Angustias Sicangco Hall, Holy Angel University, Angeles City. There were 116 participants composed of faculty and senior engineering students from the University of Assumption, Don Honorio Ventura Technological State University, and the host Holy Angel University plus a lone participant from the Fontana Development Corporation located at the Clark Economic Zone. The seminar was sponsored by the Graduate School of Engineering under its Advocacy and Extension (ADEX) Program with the intention of promoting renewable energy and energy efficiency in the community.

During the seminar, Engr. Raymundo who is the Local Senior Technician (Philippines) of the GrAT (Center for Appropriate Technology) of Vienna University of Technology specifically discussed the ever increasing demand for energy consumption in the tourism industry and its participation for the large amount of CO2 emissions. Engr. Raymundo presented their project’s 3R solution, which is to reduce energy consumption, replace inefficient technologies and redesign buildings and systems. This three step method will help the industry not just to save money in the long run for its minimal energy costs, but also become a more environment friendly company.

It is important that we would be able to do our normal tasks given that we can also lessen our carbon emission. We just have to know how. The ZCR project helps us understand how we can start and its relevance in our daily lives. This strategic method will not only help the environment but will also entail the long-term savings in our homes, schools, etc. The principle is that renewable energy does not make sense without energy efficiency. It so happened that the Philippines provides a lot of room for the use of renewable energy. “It is more cost effective to save energy than to generate it from conventional or renewable sources”, says Raymundo.
Finally, he suggested that if students will get involved in the implementation of an energy management system (in accordance with ISO 50001) in this university, they can learn how to save money as well as help improve the overall environmental performance of Holy Angel University. Students will learn the knowledge and skills which they can utilize to help companies become more energy efficient in the future. Problem-solvers will be in demand in the near future especially when the price of fuel rises to a hundred pesos per liter!”

After the seminar, the participant from the Fontana Development Corporation felt the need to invite Engr. Raymundo to spread the message on renewable energy and energy efficiency to his colleagues.

The students of HAU also gave the positive reaction and were enticed to an idea that will open new doors for their future career.

light colored roofing

Urban heat island profile

Image via Wikipedia

white colored roof s 20 degrees celsius cooler than dark colored roof. see experiment below using an infrared camera.

spot 1 (white color) = 42.9 deg c

spot 3 (black color) = 64.8 deg c

painting ur roof w/ a high albedo (light colored & reflective) coating can help lower the air-conditioning expenses since dark colored roof absorbs the sun’s heat. in tropical countries like the phils., dark colored roofs should be avoided since we don’t want to heat our house coz we don’t have winter snow anyway.

dark colored roofs also contribute to ‘urban heat island effect’…..

so paint ur roof white for a cooler world…..

energy savers! do dey work?

DDR 2178 - Energy Conservation

there r lots of energy saver gadgets in d market 2day. since pple r hungry 2lower deir electric bills…dey wil do or buy anything dat will save dem money d easiest way! ‘energy conservation is doing d same things but using less electricity by implementing enercon measures’ & installing energy saving gadgets is not one of them!

tis gadgets r not cheap! good salesmen can really rip-u-off….in rural areas, pple connected w/ electric companies/cooperatives r even endorsing tis products….

dey come in different colors but dey have diff prices coz dey r sold by diff entities…

dey r being sold in malls & hardware shops all over d philippines. der is no company address so warranty claims is nxt 2imposible…dey claim very high returns….guess d only real winner in tis game is d seller…..

one should beware of pple selling expensive equipment & saying dat d fossil fuel companies r out 2get dem so dey work secretly! most likely ur buying heavy metal or cement inside a nice looking hi-tech box dat play around w/ d sine waves of d energy supply so d elec meter gets confused! u wil probably pay less 4electricity but others will pay for it since it will b included in the ‘systems loss’. & of course be careful dat u won’t caught any fire w/ dbackyard quality equipment….

i got one extreme power saver installed in my house. it sucks up 20watts wen no other load is present according 2my power meter. it lowers d energy consumption by almost d same wattage wen loads r present specially induction motors, e.g. refs & washing machines. d salesman told me great savings especially if i buy more units!
