LEED certification rewards measurable performance, not good intentions — every credit needs documented evidence, and missing that evidence late in a project is far more costly than planning for it early. As a LEED-certification consultant based in Jakarta, ALTA Integra guides projects through LEED certification from initial scorecard strategy through to final documentation submission.
Our scope covers credit-feasibility scorecarding at the earliest design stage, energy and water modelling to substantiate performance credits, material and indoor-environmental-quality documentation tracking throughout construction, and direct liaison with GBCI reviewers through the submission and response cycle. We identify the most achievable credit pathway for a project's actual budget and site constraints, rather than chasing every possible point regardless of cost.
We track documentation from design through construction so nothing is scrambled together at the deadline, and we support the project through GBCI's review comments and resubmission process until certification is formally awarded.
WELL certification centres the building around the people who use it — air, water, light, and comfort measured against their actual effect on occupant health, not just code compliance. As a WELL-certification consultant based in Jakarta, ALTA Integra leads WELL certification with a human-centric approach, improving air, light, comfort, and wellbeing for occupants.
Our scope covers feature-by-feature gap analysis against the WELL Building Standard's concepts, indoor-air-quality and water-quality testing to substantiate precondition and optimisation features, light and acoustic performance documentation, and coordination of the policy and operational features (cleaning protocols, mental-health resources) that WELL certifies alongside the physical building. WELL uniquely certifies operations, not just design, so we work with building management as much as the design team.
We coordinate the independent WELL Performance Verification testing required for certification, and support the project through IWBI's review process — because WELL points are earned through demonstrated performance, not documentation alone.
Certification scorecards demand proof, not projections — energy modelling is how a project demonstrates, before construction, that it will actually hit the performance targets a credit requires. As a certification energy-modeling consultant based in Jakarta, ALTA Integra runs energy modelling and simulation to verify performance targets and support certification compliance.
Our scope covers whole-building energy simulation calibrated to certification-specific baselines (ASHRAE 90.1 Appendix G, or the relevant local baseline), parametric comparison of mechanical and envelope strategies against energy-credit thresholds, water-use modelling for water-efficiency credits, and documentation packaged specifically for the reviewer's expected format, not just an engineering report. Certification reviewers work from standardised templates, so modelling output that isn't formatted to match creates avoidable review delays.
We track model assumptions against as-built conditions through construction, and where an as-built change threatens a credit's compliance, we flag it early enough for the design team to respond — because a certification model is only useful if it stays accurate through to hand-over.
Indoor environmental quality is where sustainability and human experience meet directly — air, acoustics, lighting, and thermal comfort are what occupants actually feel every day, regardless of a building's energy score. As an indoor-environmental-quality consultant based in Jakarta, ALTA Integra optimizes air quality, acoustics, lighting, and thermal comfort to create healthier, higher-performing interiors.
Our scope covers low-emitting-material specification and indoor-air-quality testing, daylighting and view-access analysis for occupant wellbeing credits, thermal-comfort verification against ASHRAE 55, and acoustic-performance documentation coordinated with our own acoustic-engineering practice. These four factors interact — better daylight can mean more heat gain, better acoustic isolation can mean less natural ventilation — so we optimise them together rather than crediting each in isolation.
We verify indoor environmental quality with post-occupancy measurement wherever a certification pathway allows it, because occupant satisfaction surveys and field data are the real test of whether a certified building performs the way its scorecard claims.
Daylight and thermal comfort credits are among the most scrutinised in any green-certification scorecard, because they're also among the easiest to get wrong through oversimplified simulation. As a green-certification daylight and comfort consultant based in Jakarta, ALTA Integra assesses daylight and thermal comfort through simulation to balance wellbeing, energy, and certification credits.
Our scope covers spatial daylight autonomy (sDA) and annual sunlight exposure (ASE) simulation to the certification's exact framework, thermal-comfort modelling against PMV/PPD and adaptive-comfort models depending on the space type, glare analysis at actual occupant eye-level rather than a simplified floor-plate average, and coordination between daylight and thermal strategies since more glazing for daylight credit can undermine a thermal-comfort credit elsewhere.
We model to the specific software and framework each certification body expects (they are not interchangeable), and cross-check results against field measurement where feasible — because a credit submitted on a modelling technicality that doesn't reflect real occupant experience is a fragile credit to defend under review.
Investors, tenants, and regulators increasingly ask for carbon data a building can't produce after the fact — ESG reporting requirements are moving faster than most portfolios' data infrastructure. As an ESG and carbon-strategy consultant based in Jakarta, ALTA Integra aligns building performance with ESG goals and carbon-reduction targets to support sustainable, future-ready assets.
Our scope covers embodied- and operational-carbon baseline assessment, carbon-reduction pathway modelling aligned with science-based targets, ESG-reporting data-infrastructure design (metering, sub-metering, and data-collection points built in from the start), and portfolio-level carbon benchmarking so ownership can compare assets consistently across a diverse portfolio. We treat carbon accounting as an engineering deliverable requiring real measurement infrastructure, not a spreadsheet exercise done after the fact.
We coordinate with sustainability and finance teams so carbon strategy connects to the metrics investors and regulators actually ask for, and we design metering and reporting systems that keep producing usable ESG data for the building's operating life, not just at hand-over.
