Hi, 90.1-2007 confuses me a little. Our project (4 story, 9000 m²/90000 ft²) is located in climate zone 1b. The proposed building is heated by an electrical heatpump.

I've gone through the threads and can't find a response for a question like this, there must be one, but we have a theater project with all of the speciality lighting associated with this use.

Dear all, We are doing a factory project in pakistan, which have a 1200 kw process machinery load, after energy modeling without process load we are saving 55 % from baseline but after adding proce

“We are working on an existing classroom and office building at the University of Hawaii, which will undergo a complete remodeling under LEED-NC v.3.0.

Table G3.1 in Appendix G requires only conditioned space be simulated as being both heated and cooled in the proposed design.

Hello, When I generate the EAc1 Summary Report in HAP I have a negative percent savings in space cooling and heating in the performance rating table.

Hello Marcus. The fenestration supplier of a project gave us SHGC values from a simulation. We would like to know if it is acceptable for LEED simulation.

The efficiency of the boiler that I’m modeling has to respect Table 6.8.1F of ASHRAE 90.1:2007.
