It has been argued that the public can’t tell the difference between a building and a green building, from the outside buildings “look” the same. And advocates have argued the improved productivity is the key metric, although measuring that is a really challenge.
The Hong Kong Building Energy Code version 2012 rev1 and 2015 Lighting Power Density (LPD) requirement does NOT apply where the room lighting load does not exceed 100 watt (2012 rev1 page 13) and 70 watt (2015 page 14) respectively.
by implication the target is the TOTAL power (lighting and control gear). So what does that mean? for BEC 2015, it means a store room with total power is less than 70w you are not required to comply with the 9w/sqm LPD or the lighting control requirement.
Autocad 2017 follows the now annoying and traditional model, frequent incremental updates to extract the most money from users as possible. This latest version, takes longer to load than I can bear, and adds little functionality over the 2000 version, it should be better but sadly it is not.
Sure there are some minor incremental improvements, but nothing to write home about. In my world which is essentially 2D drafting, useful features are now hidden, requiring time consuming research for the 2017 version.
If you are a CAD user you know that screen real estate is important for productivity, the more you can see on the screen, the more you can do without wasting time zooming, right! But the new 2017 out of the box, wastes that real estate with enormous icons across the top of the screen. those are valuable pixels we need for work! there must be some way to switch to text, but research is needed to fix it, and I don’t have the time to go hunting for solutions. To me it proves that Autodesk is not serious, beginners will find the huge icon useful I guess, but I have been using Autocad for more than 20 years, I have my own shortcuts, to suit my work and I bet other users have the same set up, But every time Autodesk issue a new version I have to track down and edit the .pgp file.
Soon 2018 version will be issued, an architect somewhere will use it, forcing the rest of the design team to follow suit. Perhaps it is time to add an extra clause in the fee agreement to cover the cost for these incessant and largely unnecessary upgrades. Autocad block handling has never caught up to users real needs, perhaps by version 2020 they will catch up and understand some BASIC drafting needs, but don’t hold your breath.
Since 2000 Hong Kong installed approximately 9000 (wet) cooling towers according to EMSD, these provide heat rejection for comfort air conditioning, it follows the HKSAR Government policy to reduce energy consumption by 1,360 million kWh, and resultant greenhouse gas emissions by 950,000 tonnes annually.
Trying to do the “right thing” can seem somewhat overwhelming, sustainability has countless facets, we face too many issues where to start? You can’t change the whole world overnight right! One approach that works, pick ONE thing.
Focus on that single issue, overtime it will become second nature, once the habit is formed, then you can tackle the next topic. For me switching from canned shaving foam means the metal can, and propellent gas impacts are averted. Pick one thing!
