설비건설업을 하다보면 여러 가지 자재들을 사용해야 한다. 하지만 비슷한 제품을 우리가 시공하는 현장에 어떤 제품이 적합한 것인지 궁금할 때가 많다. 더욱이 제품 특징 및 단가 등을 알고 싶을 때 일일이 찾아봐야 하는 번거로움이 따른다. 본지는 회원사의 설비자재에 대한 궁금증을 해소하기 위해 지난해 6월호부터 특정 자재를 선정하여 제품의 특징, 용도 등을 담은 '자재의 모든 것'을 게재한다.

The amount of water resources that can be used tend to be decreased gradually. In contrast, the rapidly increasing water consumption is a problem that need to be addressed. Renovation and equipment replacement to improve energy efficiency and to reduce expenditure for building usage is required. But the excessive initial investment cost and the prolonged of pay back period may be uneconomical choice. Water usage for cleaning the toilet bowl accounts for 27%of the total water usage. Water-saving valve that can select the amount of water for cleaning toilet bowl can be reduced expenditure. After installing water-saving valve, analysed the economic effects. Water-saving valves compared with flush valves, and researched the amount of water usage. Then analyzed for the economic effects. Water-saving valve was used 5.6 ${\ell}$/time for cleaning toilet bowl. In contrast, flush valve was consumed 8.4 ${\ell}$/time. Water-saving valve's water-saving rate was 33.3%. The initial payback period for Water-saving valve was 459.5 days. By a small investment in water saving valve, the economic benefits can be obtained.
